AMSAT Mail Alias Service to End — FINAL NOTICE!

A long-standing member service, the AMSAT Mail Alias Service was scheduled to end on August 31, 2024, but a day or two of grace period has been added.

Members should understand that the email alias service, the news and bulletin board subscription lists and the membership portal are three separate systems.

Persons using the Mail Alias Service should immediately migrate to a different email account so they do not lose receipt of personal emails. Notify your friends and business accounts of the change.

Persons wishing to continue to receive AMSAT News Service Weekly Bulletins and AMSAT-BB posts or official messages from AMSAT itself should update their subscription addresses at https://mailman.amsat.org/

Members are especially asked to make sure they are NOT using a [email protected] as their registered email address in the AMSAT membership portal. Members can easily change their registered member email address by logging into the portal and updating their profile at https://mailman.amsat.org/.

A mail alias on AMSAT.ORG permitted people to send an email to members without knowing their actual internet email address. They just needed to know their amateur radio callsign.

Unfortunately, the unchecked rise in domain name hacking and email account high-jacking has made it impossible to sustain this service at a cost-effective level. The number of [email protected] email accounts that had been hijacked and converted to zombie spam accounts over the years had led many internet service providers and gateway centers to ban all @amsat.org email addresses, including those business accounts of AMSAT officers and officials. The tireless efforts of AMSAT’s all volunteer IT staff has worked for years to repair much of the damage, but AMSAT still get complaints from members who are not getting their personal emails, ANS bulletins or AMSAT-BB posts because of persistent delivery problems.

It has come to the point where the AMSAT volunteer IT staff can no longer keep up with the maintenance requirements to keep the alias mail list clean and to work with email gateways to remove blocks. And, after considerable investigation into alternative paid email services, AMSAT leadership decided that the money required to keep an email alias system alive would be better spent on building and flying satellites for its members.

Japanese Company Takes First Step Toward Removing Space Junk

There are more than 2,000 mostly intact dead rockets circling the Earth, but until this year, no one ever launched a satellite to go see what one looked like after many years of tumbling around the planet.

In February, a Japanese company named Astroscale sent a small satellite into low-Earth orbit on top of a Rocket Lab launcher. A couple of months later, Astroscale’s ADRAS-J (Active Debris Removal by Astroscale-Japan) spacecraft completed its pursuit of a Japanese rocket stuck in orbit for more than 15 years.

ADRAS-J photographed the upper stage of an H-IIA rocket from a range of several hundred meters and then backed away. This was the first publicly released image of space debris captured from another spacecraft using rendezvous and proximity operations.

Since then, Astroscale has pulled off more complex maneuvers around the H-IIA upper stage, which hasn’t been controlled since it deployed a Japanese climate research satellite in January 2009. Astroscale attempted to complete a 360-degree fly-around of the H-IIA rocket last month, but the spacecraft triggered an autonomous abort one-third through the maneuver after detecting an attitude anomaly.

ADRAS-J is the first mission to approach a piece of space debris, which comes with more challenges. The H-IIA upper stage lacks laser reflectors and targeting aids that would help an approaching spacecraft navigate its way closer.

A few years ago, the Japan Aerospace Exploration Agency (JAXA) cinched a public-private partnership with Astroscale to demonstrate technologies the private sector could use to remove large pieces of space debris littering low-Earth orbit. The same robotic technologies could also apply to satellite servicing or refueling missions.

With more financial assistance from JAXA, Astroscale is developing a follow-on mission called ADRAS-J2 to dock with the same H-IIA rocket visited by the ongoing mission, then steer it on a trajectory to reenter the atmosphere. Astroscale hopes a successful demonstration of this capability on the ADRAS-J2 mission will lead to more contracts from commercial or government operators to remote large pieces of space junk from orbit.

An H-IIA upper stage similar to the one visited by Astroscale’s demo mission broke apart in 2019, creating more than 70 new debris fragments in low-Earth orbit. A predicted close flyby by one of the pieces from the H-IIA upper stage prompted the International Space Station to fire its engines to move out of its path in 2020.

Halibut Electronics Releases New EggNOGS Kit for Satellite Antennas

Halibut Electronics has announced the release of its latest product, the EggNOGS kit, designed to facilitate the construction of Egg Beater antennas. This kit is aimed at amateur radio enthusiasts and satellite operators who wish to enhance their communication capabilities, particularly with the SatNOGS network. Priced at $79.00, EggNOGS is available for purchase through Halibut Electronics’ website at https://electronics.halibut.com/product/eggnogs/.

The EggNOGS kit is engineered to address the complexity of building Egg Beater antennas, which are known for their use in satellite communications. The kit includes a range of specialized components that are not typically available at local hardware stores. These components feature a band-specific phasing board that creates a 90-degree phase shift, a critical element in the construction of effective quadrature-fed antennas.

Currently, the EggNOGS kit supports several frequency bands: 137.5MHz, 145.9MHz, 388.0MHz, 401.0MHz, and 436.5MHz. However, due to high demand, the kits for the 137.5MHz and 145.9MHz bands are temporarily out of stock and are expected to be back in inventory by August 28th. Customers can place back orders for these bands in the interim.

The EggNOGS kit is designed to be versatile, compatible with various types of quadrature-fed antennas beyond just Egg Beaters. It can be used with turnstiles, helicals, and other balanced VHF/UHF antennas. Additionally, it works with any radio system, including low-power transmitters, making it a flexible option for a range of communication needs.

The kit includes essential parts such as circuit boards for signal routing and phasing, a common mode current choke, and stainless steel mounting hardware. Builders will need to source additional materials, such as a section of PVC pipe and materials for the aerial loops and ground plane, from local hardware stores. The default feed point connector is SMA, but there is an option to upgrade to BNC or Type-F connectors.

The EggNOGS kit is capable of handling moderate transmit power, with the upper limit still being determined but expected to range between 15W and 50W. The kit is confirmed to handle up to 10W without issues. Halibut Electronics invites feedback from users who may need phasing boards for additional frequencies not currently offered, with the possibility of expanding the product line based on customer demand.

UNNE-1 and MARIA-G Launch Delayed Until 2025

Due to the significant damage to the RFA’s One launcher stage during the static firing test at SaxaVord’s spaceport in the Shetland Islands, Scotland (UK) on August 19th, AMSAT-EA’s UNNE-1 and MARIA-G satellites launch will be delayed.

They were originally planned for launch on September 30th, and now it is not expected before 2025. Video of the BBC’s coverage of the incident is available here:
https://www.youtube.com/watch?v=DgEn6-8ekJQ

UNNE-1 and MARIA-G are both based on the currently orbiting HADES-D (SO-121) hardware, providing a repeater service for voice and data communications in FM and FSK-derived modes. They have been designed and built by AMSAT-EA together with private sector companies and with the collaboration of Universities and educational centres.

Both satellites will offer licensed radio amateurs around the world the opportunity to make FM and FSK QSOs, including FT modes, such as FT-4 and FT-8, or AX.25/APRS. The satellites will also transmit telemetry with their status, voice messages and CW.

UNNE-1 includes an Arduino-based board with software from Nebrija University of Madrid. The students have developed a small decoding game with a space story as a background. The satellite sends a clue each week in its FSK telemetry so that radio amateurs can solve the challenge. This game will be detailed on the AMSAT EA website and on the Nebrija University one.

MARIA-G also includes two CW reception games/challenges implemented by students from the María Guerrero high school in Collado Villalba, also from the region of Madrid.

One of the games consists of receiving the coordinates of a significant place on Earth (for example a city, a monument…) and the other about receiving a code that will correspond to a question about Science. Both games will have a dedicated web page.

MARIA-G also includes a small experiment, developed by the Fraunhofer-Gesellschaft research center in Germany. It consists of a proof of concept for the transmission of a TS-UNB waveform from a low Earth orbit. Therefore, it will transmit a TS-UNB message according to the ETSI-TS-103-357 standard. It is intended solely as a research and development project with no commercial intention.

The ITU modulation classification would be 100K W2DWW but the bandwidth will be reduced. The operation of this experiment will be carried out by AMSAT-EA.

The UNNE-1 and MARIA-G satellites are part of the Erminaz mission, a joint effort of AMSAT-DL, AMSAT-EA and LibreSpace Foundation, each organization flying its own satellites and using LibreSpace’s PicoBus deployer.

The mission management with the German Space Agency (DLR) and the launcher (RFA), as well as with the UK authorities, has been carried out jointly, with AMSAT DL leading it.

Paul D. Graveline, K1YUB, Silent Key

With heavy hearts, AMSAT and The AMSAT Journal mourn the passing of Journal assistant editor, Paul D. Graveline, K1YUB, on August 19, 2024.

Paul served as an assistant editor for the past seven years, starting with the July/August 2017 issue. In addition to his editing and authoring contributions to the Journal, Paul also served as an active member of the CubeSatSim Educational Materials Team for AMSAT’s Educational Relations program.

Here is how Paul described his ham radio exploits:

“Like many future hams in the 1960s, I became interested in radio by listening to shortwave stations on my grandfather’s old huge Philco radio.

“In 1960, I got a Hallicrafters S120 short wave receiver for Christmas, and I was hooked. A year later, K1DEN got me interested in ham radio. I was issued KN1YUB as a novice, and in 1963, I upgraded to General and K1YUB, which I still use today. Most of my ham operating has been using CW.

“By 1973, I passed my Advanced and Extra which required 20 wpm skills.

“In the 1980s, I worked and taught Novice and General license courses at Tufts Radio in Medford, MA. My time at Tufts included numerous ham conventions from Denver to Clearwater.

“Along with K1TW, I helped reestablish the shortwave focused Boston Area DXers which met on the third Friday of every month. Nearly 35 years later, we still do!

“More recently, I have been spending time in activities to support ham radio.

“For a number of years, I’ve been an Assistant Editor for The AMSAT Journal as well as being engaged, along with KU2Y, KD2XS , KK6NOW and WD6DRI, on an AMSAT project developing the CubeSat Simulator as a learning tool.

“I began following the space weather bulletins from Dr. Tamitha Skov, WX6SWW, better known as “The Space Weather Woman,” a few years back and now am a member of her steering committee, as well as being the Coordinator for her new Super Community project with the objective of sharing space weather knowledge across stakeholder communities like Aurora Chasers and Ham Radio operators. I did a cover story of Dr. Skov in The AMSAT Journal.”

Paul’s good humor, dedication, enthusiasm and many contributions to AMSAT and the larger amateur radio community will be greatly missed.

Changes to AMSAT-NA TLE Distribution

Two Line Elements or TLEs, often referred to as Keplerian elements or keps in the amateur community, are the inputs to the SGP4 standard mathematical model of spacecraft orbits used by most amateur tracking programs. Weekly updates are completely adequate for most amateur satellites. TLE bulletin files are updated daily in the first hour of the UTC day. New bulletin files will be posted immediately after reliable elements become available for new amateur satellites. More information may be found at https://www.amsat.org/keplerian-elements-resources/.

No changes have been announced for this week.

Satellite Shorts From All Over

+ The FUNcube Data Warehouse will be going off line on Saturday, August 31, as it transitions to a new server. The service may be down for about three days as the team has to migrate the large amount of data collected over 11 years and ensure that the service is running correctly. The dashboards will catch up if they are left connected, once the service comes on line. The team will probably turn on the collection service before the UI so that there is not to much data loss. (ANS thanks Dave Johnson, G4DPZ, of the FUNcube Team for the above information.)

+ NASA will return Boeing’s Starliner to Earth without astronauts Butch Wilmore and Suni Williams, KD5PLB, aboard the spacecraft, the agency announced last week. The uncrewed return allows NASA and Boeing to continue gathering testing data on Starliner during its upcoming flight home, while also not accepting more risk than necessary for its crew. Wilmore and Williams, who flew to the International Space Station in June aboard NASA’s Boeing Crew Flight Test, have been busy supporting station research, maintenance, and Starliner system testing and data analysis, among other activities. They will continue their work formally as part of the Expedition 71/72 crew through February 2025, and will fly home aboard a Dragon spacecraft with two other crew members assigned to the agency’s SpaceX Crew-9 mission. Starliner is expected to depart from the space station and make a safe, controlled autonomous re-entry and landing in early September. (ANS thanks NASA for the above information.)

+ NASA astronaut Nick Hague, KG5TMV, and Roscosmos cosmonaut Aleksandr Gorbunov will launch no earlier than Tuesday, Sept. 24, on the agency’s SpaceX Crew-9 mission to the International Space Station. NASA astronauts Zena Cardman, KJ5CMN, and Stephanie Wilson, KD5DZE, previously announced as crewmates, are eligible for reassignment on a future mission. The updated crew complement follows NASA’s decision to return the agency’s Boeing Crew Flight Test uncrewed and launch Crew-9 with two unoccupied seats. NASA astronauts Butch Wilmore and Suni Williams, KD5PLB, who launched aboard the Starliner spacecraft in June, will fly home with Hague and Gorbunov in February 2025. (ANS thanks NASA for the above information.)

+ The U.S. National Science Foundation National Radio Astronomy Observatory (NSF NRAO), and its administrator Associated Universities, Inc. (AUI), have created SuperKnova, an online educational platform that provides inclusive, equitable access to radio technology learning and training. Thanks to a generous grant from Amateur Radio Digital Communications (ARDC), learners can now enroll in two self-paced courses to learn the fundamentals of radio communications. The Technician Amateur Radio License and EMS Course introduces learners to the electromagnetic spectrum using amateur (ham) radio as a vehicle. (ANS thanks the National Radio Astronomy Observatory for the above information.)

+ Alick Gardiner, 2E0HDV, has undertaken a “retro radio” project to utilize the APRS packet digipeater aboard the International Space Station with equipment dating back to the 1980s!

ROBUSTA-3A in Orbit

When the long-delayed inaugural launch of the European Space Agency’s (ESA’s) new Ariane 6 rocket finally occurred on July 7, it suffered an upper stage failure that left some payloads in the wrong orbits. Fortunately, before the anomaly developed, the Ariane 6 successfully deployed ROBUSTA-3A, a satellite with an amateur radio payload. The target was a 580 km circular orbit with an inclination of 96 degrees.

ROBUSTA-3A (a.k.a. “Méditerranée”) is a 3U cubesat, designed and built by students and faculty of Université de Montpellier in southern France. Over a decade in development, involving around 300 students from the University of Montpellier and all over the world, ROBUSTA-3A will be its seventh satellite developed entirely in-house, having learned much from the development and launch of smaller ROBUSTA-1U satellites. The project has offered hands-on training, engineering and scientific experience to the next generation of space engineers and researchers.

The satellite’s primary mission is weather observation, specifically to track “Cevenol events.” These are intense storms and incredibly heavy rains that cause extensive flooding, often in the form of flash floods, that hit the plains and the foothills of southern France. Once considered “100-year storms,” they have been occurring with greater frequency due to global climate change. Most of the weather data is downlinked on a commercial S-band microwave frequency.

“If the data we will be collecting improves the geographic and temporal accuracy of weather forecasts for cévenol events, it would help authorities give early warning to the population and allow rescue services to better target the areas at risk,” explains Romain Briand, assembly integration and testing manager at the University Space Center of Montpellier.

Robusta-3A under development by Centre Spatial Universitaire de Montpellier (CSUM)

However, ROBUSTA-3A aims to do even more than chart water vapour from space.

The satellite carries an experimental Attitude Determination and Control System (ADCS) that will seek to optimize solar panel exposure and correctly aim sensors and microwave downlink antennas. Using a set of Sun sensors, magnetometers, and reaction wheels in a pyramidal configuration, the system should provide precise attitude control, especially during orbital maneuvers.

The satellite will also employ a cold gas thruster propulsion system which operates with solid iodine as propellant. This system will demonstrate orbit maintenance, phasing, and lifetime extension of small satellite missions, and could also help with end-of-life decommissioning and debris mitigation.

As an extra mission, the CubeSat will test how computer memory from chip manufacturer 3D PLUS withstands the radiation of space. This French company specialises in highly-reliable electronic components and their computer memory recently landed on the Moon as part of the India’s Chandrayaan-3 lander.

Finally, ROBUSTA-3A also carries a 9k6 GMSK AX.25 store-and-forward digital system with a UHF transmitter output of up to three watts — a very powerful downlink! As the satellite is sill in commissioning, operating protocols and uplink frequency have not yet been released. However, amateurs should expect something similar to the FalconSAT-3 store-and-forward system that was popular until that satellite deorbited in January of 2023. ROBUSTA-3A is currently transmitting short telemetry bursts on its International Amateur Radio Union (IARU) coordinated downlink frequency of 436.750 MHz.

SONATE-2 APRS Digipeater in Operation

Professor Hakan Kayal from Julius-Maximilians-Universität (JMU) Würzburg in Bavaria, Germany posted on X this past week, “Thanks to everyone using SONATE-2’s APRS digipeater over the weekend. A total of 421 messages were digipeated.”

The Bayerische Julius-Maximilians-Universität Würzburg’s SONATE (SOlutus NAno satelliTE) satellite is a technology demonstration mission for highly autonomous payloads and artificial intelligence in the 6U CubeSat class. As part of the SONATE-2 mission, novel hardware and software technologies of artificial intelligence (AI) are to be verified in miniaturized format in earth orbit. By using such AI technologies, the satellite can independently analyze the environment and start autonomous recordings. Deep learning plays a special role as a versatile image processing tool. In addition to the classification of targets already known at the start of the mission, the payload should also have the option of on-board training for the detection of anomalies as previously unknown objects or phenomena.

The operation of an amateur radio payload is important to the educational mission of SONATE-2. The development and operation of the satellite is used for the education of students of the university. In cooperation with the DLR School Lab in Neustrelitz, Germany, it is planned to use the amateur radio payload for the education of high school students.

The amateur payload of SONATE-2 consists of a VHF transceiver that was already built for the predecessor mission SONATE over the course of several student projects. For SONATE-2 additional student projects extended the transceiver functionalities. It will provide regular SSTV downlinks with images from the optical sensors included in the AI payload as well as an APRS digipeater and CW beacon.

On the education side, the mission will serve as a foundation for different aspects of the university aerospace and computer science engineering program. In the context of practical courses, as thesis authors or as student assistants, students can participate in the development of all subsystems of the space and ground segment, including the amateur radio payload and the technology demonstration payload. In the context of mandatory lectures and exercises on space operations every student will also be included in the operations of the satellite.

The German Aerospace Center (DLR) offers a School Lab for high school students at the location of the external ground station in Neustrelitz, Germany. Besides experiments on space and satellites, the School Lab includes amateur radio contacts to the ISS under the supervision of licensed local radio amateurs, which they wish to extend to other satellites like in this cooperation with the SONATE-2 mission.

Besides the amateur and educational mission parts, the SONATE-2 mission also has a research objective for the demonstration of novel artificial intelligence technology in the space environments. While the AI payload is mainly operated using a separate up/downlink in the space operation service in S-band, the satellite bus and the amateur payloads are operated in the amateur service. Housekeeping telemetry in the amateur service also contains status information of the non-amateur payload.

According to Kayal, not many similar projects are currently being undertaken.

“Let’s assume that a small satellite is to investigate a new asteroid in the solar system in the future. It cannot be trained for this task on the ground, because the object of investigation is largely unknown. There is no training data, so the measurements and recordings can’t be made on the ground,” Kayal added.

Transmitting this data to Earth for initial processing and subsequently training the AI via remote control would result in significant time delays for missions located at a considerable distance from Earth.

Opting for a heightened level of autonomy with direct on-board AI support would greatly enhance the mission’s efficiency. This approach would expedite the detection of intriguing objects and phenomena on the asteroid, considerably reducing the time required for their identification.

To facilitate this, four on-board cameras capture the essential imagery required for training the AI. Initially, the AI acquires knowledge of conventional geometric patterns on Earth’s surface, among other things, which subsequently empowers it to autonomously identify anomalies.

In addition to these AI experiments, SONATE-2 carries a suite of other small satellite technologies that are ready for in-orbit testing. These technologies include an automated lightning detection and recording system, as well as an electric propulsion system developed in collaboration with the University of Stuttgart.

Kayal added, “In terms of complexity, SONATE-2 is unparalleled among nanosatellites.”

Wireless Technology Workshop in India

A special workshop on ‘Wireless Technology and its Practical Solutions’ was conducted for Rajkot – Police Wireless Department at Gujarat (India) on 20th July 2024. The venue was the Police Training Center at Rajkot Headquarter. It was a highly informative 3 hours session from 10:00 AM to 1:00 PM.

Regional Coordinator of AMSAT-INDIA & The Amateur Radio Society of India, Mr. Rajesh Vagadia, VU2EXP, gave insight into various Radio Communication protocols, types of modulation, modes & various applications used in Amateur Radio & Police department.

Rajesh Vagadia, VU2EXP (hamphotos.com)

As this workshop was targeted for 25 technical wireless officers & radio operators, we focused on the radio communication enhancing methods, utilizing various techniques, using different antennas for specific applications and diagnosis of wireless setup with various measuring instruments incl. SWR/Power Meter, NanoVNA/Antenna Analyzer. We extended a handful of maintenance tips for Radio, Antenna, Feed line & repeaters to optimize radio communications.

We also gave an overview of Ham Radio & its various events, Understanding of Digital Communication, Satellite Communication, Features of newer Digital protocol incl. DMR, D-STAR & Fusion. There was good interaction with participants, lots of doubt & queries were cleared satisfactorily. Good number of radio stuff was displayed incl. HTs, VHF Base Radio, IC-705 SDR HF Radio, RTL SDR Dongle, Antenna Tuner, CAT Control, Soundcard Interface, Morse Key, CW Paddle & Keyer, CubeSat model, Balun, LNA, SWR/Power meter, NanoVNA, Dummy load, PSU, Feed lines, EFHW Antenna, Telescopic Antenna, Connectors, Adaptors, ARISS Awards, QSL Cards etc., which helped participants to view, discuss & understand our entire stuff better.

We always give practical demos, but, here in the audience was a heavy user of CW & RT from the police dept. We didn’t give a demo of that kind hi..hi.., but surely gave demos of Digital Communication – sending text messages between two VHF Setup and a second demo of sending SSTV Images between two local vhf stations! For the audience it was interesting to learn how we ham convert simple ASCII codes to corresponding audio frequencies (for Digital Communication) and RGB pixel values of Image to Slow Scan Television format to transmit & receive ‘IMAGES’ via our standard radios! That’s why we proudly call Ham Radio the oldest Social Media!

It was a nice & fruitful workshop overall. I am thankful to Commissioner of Police Rajkot Shri Brajesh Kumar Jha Sir for approval of this workshop and Shri S K Jadeja Sir (PI Wireless) for nicely coordinating this workshop. I am thankful to our AMSAT-INDIA & ARSI (The Amateur Radio Society of India) for their great support and guidance to make this workshop highly successful.

We wish Rajkot Gujarat Police will utilize the gained knowledge & implement into the system for better productivity!

Small Satellites of the Future Grow Larger

Small satellite companies that have grown out of the New Space boom are retiring the cubesat platforms that made them to focus on larger, more powerful next-get small sats that promise to unlock new possibilities with advanced AI and real-time laser-based inter-satellite communications.

Over the past 15 years, small satellites have revolutionized how things are done in space. Built quickly from cheap, off-the-shelf components, and small enough to hitch an affordable ride to orbit on the back of bigger missions, these devices and the young, agile New Space companies behind them taught the old-school space industry a few lessons.

But New Space is coming of age and the firms behind the small satellite revolution must live up to expectations less favorable to their trade-mark experimental ethos. The lowest cost and shortest time to orbit may no longer be the technology’s biggest draw as users want maximum return on investment and require granted reliability. The firms behind the disruptive tech, however, have grown up together with their market share and are tapping into emerging innovation, looking to unleash a whole load of new applications in the coming years.
The Evolution of the Smallsat

Satellites started small. The first U.S. satellite, Explorer 1 — launched in 1958 — weighed only 14 kilograms. But the technology, prized for opening a whole new perspective on our planet, quickly bulked up, enabled by the increasing lifting powers of fast-evolving rockets. Soon, complex satellites the size of a school bus took over, observing the planet from above, broadcasting TV signals across continents and sensing the environment around them.

It was only in the mid-1980s that researchers renewed their interest in smaller satellites with masses of tens to a couple of hundred kilograms. The true small sat revolution, however, began in 1999, with the invention of a cubesat. Based on standardized satellite units of 10 by 10 by 10 centimeters in size, cubesats opened space to anyone with enough technical skill to assemble and operate them. Soon, university teams from all over the world began launching their own experimental spacecraft to provide their students with hands-on space tech experience.

By 2014, San Francisco-based Planet Labs launched its first commercial constellation of 28 three-unit (3U) Earth-observing cubesats called Doves. More than 120 Doves are in orbit today, capturing an image of each place on Earth more than once a day. Other companies followed suit. As of today, cubesats have made it to orbit around Mars and the Moon and observed the impact of NASA’s Double Asteroid Redirection Test (DART) into the asteroid Didymos in 2022 in real-time.

Larger small satellite platforms — up to 500 kg in mass — have also grown in popularity. In fact, these larger small satellites today dominate space around Earth thanks to SpaceX’s constellation of Starlink internet-beaming satellites.

Consulting firm Novaspace predicts that 26,104 small satellites — including minisatellites of 100 to 500 kg in mass, microsatellites between 10 and 100 kg and nanosatellites as light as 1 to 10 kg — will launch in the next decade.

And although the smallsat revolution is already behind us, new technologies are emerging that promise to supercharge the sector in the coming years. Via Satellite spoke with a number of experts in the field about what the smallsat of the future will look like.

ASRTU-1 Scheduled for November Launch

Published flight manifests indicate that the Chinese amateur radio satellite ASRTU-1 has been scheduled for launch in November of this year aboard a Russian rocket. As always, launches are subject to a wide variety of variables, and space agencies are not always 100% forthcoming about their activities. So while you may not want to mark the calendar just yet, hopeful signs are pointing toward a launch in the coming months.

Artist’s sketch of ASRTU-1

ASRTU-1 is a 12U Cubesat mission designed by Russian and Chinese university students for education and amateur radio. Harbin Institute of Technology has successfully developed several amateur radio satellites, including LilacSat-2 (CAS-3H), LilacSat-1 (LO-90), DSLWP-A (LO-93) and DSLWP-B (LO-94). The partner institution is Bauman Moscow State Technical University, which constructed two satellites, Baumanets-1 in 2006 and Baumanets-2 in 2017, both of which unfortunately failed to reach orbit due to launch failures unrelated to the satellite payloads.

The amateur radio station onboard ASRTU-1 will provide FM and telecommand uplinks, as well as FM, telemetry, and digital image downlinks. A new SDR based transceiver was developed to provide communication and experimental resources to radio amateurs, including a V/U FM transponder, a UHF telemetry downlink, and a 10.5G image downlink.

The repeater uplink will be on 145.875 MHz FM using a 67 Hz CTCSS (PL) tone. Downlink will be on 435.400 MHz FM. The telemetry beacon will be on 436.210 MHz using 9k6 bps BPSK.

In addition to the FM repeater, the satellite will also provide an open telecommand system to allow radio amateurs to send commands to control the satellite to take and download images. X Band image downloads using 1 Mbps/10mbps QSPK will downlink on 10.460 GHz.

ASRTU-1 has been scheduled for a Roscosmos launch from Vostochny Cosmodrome, Asiatic Russia, in Q4 2024 into a 530 km Sun-synchronous Orbit (SSO). Downlinks and the repeater uplink have been coordinated by the International Amateur Radio Union (IARU).

Satellite Shorts From All Over

+ The MESAT-1 team are continuing to test and commission the satellite. It is currently in Health Mode transmitting continuously and the downlink power is now about 6dB higher. So it should be easier to hear and decode. If you have had trouble decoding it then now is a good time to try again. Software may be downloaded from https://www.amsat.org/foxtelem-software-for-windows-mac-linux/ (ANS thanks Chris E. Thompson, VE2TCP / G0KLA / AC2CZ, for the above information.)

+ SpaceX is now targeting mid- to late August for the launch of Polaris Dawn, a mission funded by billionaire entrepreneur Jared Isaacman. The upcoming flight, which will employ SpaceX’s Crew Dragon spacecraft and Falcon 9 rocket, had been slated to lift off no earlier than July 31. SpaceX announced the delay today (July 26), during a press conference focusing on the company’s upcoming Crew-9 astronaut mission to the International Space Station (ISS) for NASA. The NASA mission will include Zena Cardman, KJ5CMN, Nick Hague, KG5TMV, Stephanie Wilson, KD5DZE, and Aleksandr Gorbunov, Roscosmos. Crew-9 will launch no earlier than Aug. 18, and Polaris Dawn will fly sometime after that, the company said. The Polaris Dawn mission is scheduled to include the first-ever private spacewalk. (ANS thanks Space.com for the above information.)

+ The U.S. military is installing modular state-of-the-art satellite jammers capable of disrupting Russian or Chinese communications, should the need arise. Even though the hardware is ground-based, the U.S. Space Force will oversee installation and operation. The technology is already past prototyping. The military tested the system at two different locations earlier this year. The Department of Defense allocated funds to build 24 remote installations, with 11 scheduled to deploy before the end of the year. (ANS thanks SatNews.com for the above information.)

+ SpaceX Falcon 9 returned to flight with three Starlink launches in 30 hours after only 15 days of being grounded due to its recent upper-stage anomaly (a brittle, and presumably cracked, pressure monitoring line) and conducted its 300th reflight of a booster. (ANS thanks The Orbital Index for the above information.)

ANS-189 AMSAT News Service Weekly Bulletins

DATE 2024 July 7

Firefly Delivers New Amateur Satellites to Orbit

The Firefly Alpha FLTA005/NASA ELaNa 43 mission, nicknamed “Noise of Summer,” launched successfully at 04:04 UTC on July 4 (Wednesday evening, July 3 in the U.S.) and deployed eight new cube satellites to Low Earth Orbit (LEO). Five of these cubesats carry amateur radio equipment.

The cubesats were placed into a sun-synchronous Earth orbit, meaning that all locations on earth will see high-elevation passes roughly between 8:00 and 10:00 a.m. and between 8:00 and 10:00 p.m. local time daily, with lower elevation passes earlier and later.

Among the newly-deployed satellites, the one of greatest interest to the amateur radio community is MESAT1. Built by the University of Maine, in cooperation with AMSAT, this satellite carries a 30 kHz wide V/U Transponder plus a 1k2 BPSK telemetry downlink. Telemetry downlink 435.800 MHz with transponder downlink 435.810-435.840 MHz, and transponder uplink 145.910-145.940 MHz. Amateurs are encouraged to use AMSAT’s FoxTelem software to collect telemetry.

MESAT1 involves three missions designed by high school students in Maine. The science payloads are climate focused and include ALBEDO, IMAGER, and HAB. These will identify urban heat islands, determine concentration of phytoplankton in water bodies, and help predict harmful algal blooms. Four multispectral cameras on board will relay the data down to University of Maine’s ground station for further processing. Amateurs are encouraged to use AMSAT’s FoxTelem software to collect telemetry and assist in these science projects.

Also deployed was CatSat, a technology demonstration of an inflatable antenna for high-speed communications, built by the University of Arizona. CatSat’s deployable antenna consists of a Mylar balloon. The front half of the balloon is transparent, allowing microwaves to pass through. The back half of the balloon is aluminized, creating a reflecting antenna. After reaching low Earth orbit, CatSat’s antenna will deploy and inflate to a diameter of just over one-and-a-half feet CatSat’s demonstration will be to transmit high-definition Earth photos to 10 GHz, X-band ground stations at ~50 megabits per second.

In addition to images, data about the structure of the Earth’s ionosphere will be gathered by listening-in to thousands of beacons from ground-based ham radio stations. CatSat will relay WSPR and FT8 signals from HF. Downlinks on 437.185 MHz and 10470.00 MHz.

Other satellites with IARU-coordinated amateur frequency downlinks include:

Serenity, which uses a 4k8 FM with AX25 downlink on 437.100 MHz. Serenity was built by Teachers in Space, Inc., a 501(c)(3) nonprofit educational organization in North America that stimulates student interest in science, technology, engineering, and mathematics (STEM). They provide teachers with real space science experiences, space flight opportunities, and industry connections.

KUbeSat-1, revives small satellite research at the University of Kansas and starts a new KUbeSat program that will offer space access to student research. The main payload on KUbeSat-1 is the Primary Cosmic Ray Detector which will use a new method to measure the energy and species of primary cosmic rays hitting the Earth. The secondary payload is the High-Altitude Calibration, (HiCalK) that builds on decades of research surrounding Very High Frequency signals generated by cosmic ray interactions with the atmosphere. UHF downlink using 9k6 GMSK. A downlink on 437.085 MHz.

SOC-i (Satellite for Optimal Control and Imaging) is a technology demonstration mission of attitude control technology and a camera that serves as an instrument to demonstrate SOC-i’s pointing abilities. Developed at the University of Washington, SOC-i has a UHF downlink using 4k8 GMSK. downlink 437.125 MHz.

Ariane 6 Maiden Flight With GENESIS-A Module

The maiden flight of the new European launcher, Ariane 6, is scheduled for July 9, 2024, with a launch window of 3:00 p.m. to 7:00 p.m. local time from the European spaceport in French Guiana (July 9 20:00h to July 10 00:00h CEST). Among many other payloads, it carries our (inside YPSAT) GENESIS-A module, attached to the second stage of the launcher. The module will transmit FT8 and live SSTV images in Robot 36 format.

FT8 transmissions are made every 16 seconds, while SSTV’s are every 5 minutes.

The working frequencies are as follows:

Downlink 144.175 MHz FT8 Mode:

– Callsign AO4ARI HO60 if the antenna has been deployed
– Callsign AO4ARI HO61 if the antenna has not been deployed

Downlink 144.550 MHz SSTV Robot 36 mode with live image and Hades text

A carrier with a frequency of 144.550 MHz (same frequency as SSTV) is left between FT8 tones.

This information is compiled in PDF in the following document on our web:
https://www.amsat-ea.org/app/download/13458580/AMSAT+EA+-+GENESIS-A+transmissions+description.pdf

The only thing ESA has given us is the trajectory over the ground while flying over Europe, but we don’t have TLEs or anything that we can semi-automate. It is available on our website:
https://www.amsat-ea.org/s/cc_images/cache_19006006.jpg?t=1720182961

It will be very difficult to receive it but we thank you all if you try and if you spread this information to have all possible operators tuned into FT-8 that day. The module will fall into the sea with the second stage after a few hours.

Logbook of The World Returns To Service

Effective 12:00pm ET / 16:00 UTC on July 1, Logbook of The World® (LoTW®) has been to service.

As work progressed on the network, some users encountered LoTW opening briefly during which some 6600 logs were uploaded. The logs were not processed until this weekend as we tested that the interfaces to LoTW were functioning properly.

We are taking steps to help manage what will likely be a huge influx of logs. We are requesting that if you have large uploads, perhaps from contests or from a DXpedition, please wait a week or two before uploading to give LoTW a chance to catch up. We have also implemented a process to reject logs with excessive duplicates. Please do not upload your entire log to “ensure” your contacts are in LoTW as they will be rejected. Lastly, please do not call ARRL Headquarters to report issues you are having with LoTW. You can contact support at [email protected].

Through the end of the year, you may experience planned times when LoTW will be unavailable. We have been using this time to evaluate operational and infrastructure improvements we would like to make to LoTW. Those times will be announced.

We appreciate your patience as we worked through the challenges keeping LoTW from returning to service. We know the importance of LoTW to our members, and to the tens of thousands of LoTW users who are not ARRL members. LoTW, just behind QST, is our second most popular ARRL benefit.

LUSAT, Dead or Alive?

LO-19, co-ordinated by AMSAT Argentina, the LUSAT (named after the LU amateur designation for Argentina) microsatellite was launched on the first ARIANE ASAP flight V35 with SPOT 2, on the 22 January 1990 (01:35:27 GMT) into an 780 km sun-synchronous, 98 degree inclined orbit.

It carried a Digital Store and Forward packet communications transponder similar to AO-16. Downlink was AX.25 at 437.125 MHz SSB 1200 bps RC-BPSK. It is box shaped with dimensions of 213 × 230 × 230 mm, with four solar panels and weighs 13.76 kg.

Long past its expected useful life, in recent years LUSAT has only been transmitting an unmodulated carrier signal.

On June 29, Gustavo Carpignano, LW2DTZ, reported that recent observers had failed to detect the carrier. Gustavo declared LO-19 dead.

However, on July 1, Nico Janssen, PAØDLO, reported receiving the carrier, but at a signal strength much weaker than over previous years. Nico suggested that, perhaps, the onboard power amplifier has failed.

Well-equipped ground stations may wish to give a listen to test what they can hear.

LEGO Bricks Printed out of Space Dust

There have been many proposals for building structures on the Moon out of lunar regolith. But here’s an idea sure to resonate with creators, mechanical tinkerers, model builders and the kid inside us all.

What about using actual LEGO bricks?

Researchers ground up a 4.5-billion-year-old meteorite and used the dust to 3D print LEGO-style space bricks. They actually click together like the plastic variety, with so far only one downside: they only come in one color, grey.
Universe Today

Want to see some of these lunar LEGOs? LEGO will showcase the space bricks at some of its stores.

Creating building materials on the Moon or Mars from the material on hand means construction materials don’t have to be transported from Earth. This would be a huge savings in launch costs because less weight would have to be boosted from Earth.

A group of scientists from ESA (European Space Agency) were inspired by LEGO bricks, and with the advances in 3D printing, had the idea to print space bricks and test how they would work for construction.

The only problem was that except for the Moon rocks brought back by the Apollo astronauts – which are highly guarded for scientific study only — there’s not any lunar regolith available on Earth to experiment with.

But meteorite dust is a close cousin to lunar regolith. The ESA team was able to get a meteorite that was discovered in Northwest Africa in 2000 and is about 4.5 billion years old. It is made of metal grains and chondrules, similar to Moon dust.

Inspired by LEGO, ESA scientists have used dust from a meteorite to 3D-print LEGO-style ‘space bricks’
to test out construction ideas for a future Moon base. Credit: The LEGO Group

They mixed the meteorite dust with a some other things, like a polymer called polylactide and regolith simulant and 3D printed bricks that mimic and behave just like LEGO bricks. While they aren’t smooth like regular LEGO bricks, ESA said the space bricks gave ESA’s space engineers the flexibility to build and test a variety of structures using this new material.

“It’s no secret that real-world scientists and engineers sometimes try out ideas with LEGO bricks,” said Emmet Fletcher, Head of ESA’s Branding and Partnerships Office. “ESA’s space bricks are a great way to inspire young people and show them how play and the power of the imagination have an important role in space science, too.”

“Nobody has built a structure on the Moon, so it was great to have the flexibility to try out all kinds of designs and building techniques with our space bricks,” said . ESA Science Officer Aidan Cowley. “It was both fun and useful in scientifically understanding the boundaries of these techniques.”

For a list of where the lunar LEGOs will be on display worldwide, see https://www.universetoday.com/167675/lego-bricks-printed-out-of-space-dust/#more-167675

The LEGO website has additional details at https://www.lego.com/en-us/aboutus/news/2024/june/lego-bricks-scientists-build-astronaut-shelters-on-the-moon

Hopefully the lunar LEGOs will inspire both children and adults about space and to encourage them to build their own LEGO Moon bases.

Satellite Shorts From All Over

+ What GOES up … NOAA’s latest Geostationary Operational Environmental Satellite, GOES-U, launched on the first Falcon Heavy of the year on June 25 from Launch Complex 39A at Kennedy Space Center. The mission, the last of the GOES-R series of geostationary weather satellites, continuously monitors weather systems over the Western Hemisphere. Assuming that next week’s planned burn to lift the satellite to geosynchronous orbit is successful, this satellite will be re-designated as GOES-19 and will, in coming months, take over the GOES-East duties from the aging GOES-16. (See ANS 182 last week for more details.)

+ Musk come down … Elon Musk’s SpaceX has won a contract valued at up to $843 million to build a vehicle capable of safely deorbiting the International Space Station once the station is decommissioned in 2030. While many people have suggested raising the ISS’s orbit and turning it into a museum, the amount of fuel needed to move the approximately 420-ton station to a high enough orbit to remain stable for long durations is prohibitive.

+ Blow up … Russian Resurs-P1, an almost-six-ton defunct Earth observation satellite that stopped orbit maintenance in 2017 but continued operations until 2022, unexpectedly exploded last week into hundreds of fragments. Expected to reenter later this year, Resurs-P1 was orbiting at ~350 km, close enough to the ISS’s orbital altitude that the event forced ISS astronauts into shelter for an hour while debris was tracked.

+ Or go up, come down, and blow up (unexpectedly) … during a static fire test of the first stage of China’s close-to-finished Tianlong-3 rocket, the hold-down hardware failed to do its singular job: hold down the rocket. Moments after ignition, the rocket shot 1.5 km into the sky above the city of Gongyi, China. With no guidance system, gravity took over, resulting in a massive fireball on impact. Very fortunately, there were no casualties as the rocket mostly went straight up and straight back down.

Starliner Brings Another Ham to ISS

Working around multiple helium leaks and thruster problems, the crew of Boeing’s Starliner spacecraft wrapped up a challenging rendezvous and a delayed-but-successful docking with the International Space Station Thursday in a major milestone for the new ship’s first piloted test flight.

With commander Barry “Butch” Wilmore and co-pilot Sunita Williams, KD5PLB, monitoring the Starliner’s automated approach, the Starliner’s docking mechanism engaged its counterpart on the front of the station’s forward Harmony module at 17:34 UTC on June 8 as the two spacecraft were sailing 260 miles above the Indian Ocean.

After extensive checks to verify an airtight seal, hatches were opened and Wilmore and Williams floated into the lab complex to an enthusiastic welcome from the seven Expedition 71 crew members: cosmonauts Oleg Kononenko, RN3DX, Nicolai Chub and Alexander Grebenkin, RZ3DSE, along with NASA astronauts Matthew Dominick, KCØTOR, Michael Barratt, KD5MIJ, Jeanette Epps, KF5QNU, and Tracy Dyson.

Wilmore and Williams plan to spend about a week aboard the outpost before returning to Earth aboard the Starliner. While they’re there, the station crew will install a replacement urine processor pump module that was loaded aboard the Starliner at the last minute to fix the lab’s water recycling system and allow normal use of the toilet in the U.S. segment of the station.

Running years behind schedule after multiple problems that cost Boeing some $1.4 billion to correct, the Starliner was launched Wednesday with a known helium leak in the system used to pressurize the spacecraft’s propulsion system. Launch had been delayed a month, in part because of work to confirm the ship could safely be launched with the leak as is.

After reaching orbit, two more helium leaks developed that prompted flight controllers to close valves leading to the affected plumbing, or manifolds, while they analyzed leak rates and potential work arounds. Closing the manifolds took down five of 28 reaction control system jets in the ship’s service module and three of 20 more powerful “OMAC” thrusters.

Docking had to be delayed because five RCS jets were “deselected” by the capsule’s flight software when telemetry showed they were not performing exactly as expected. It was unclear if there would be sufficient maneuverability for the docking to proceed.

Throughout the process, Wilmore flew the Starliner manually, holding position about 650 feet from the space station. When ground teams concluded the spacecraft had enough thruster redundancy to proceed, the Starliner’s automated control system took over and flew the ship in for a problem-free docking.

As if the team hadn’t had enough problems to deal with, a fourth and a fifth helium leaks were detected after docking. In any case, per standard procedure, flight controllers closed all the Starliner’s helium manifolds after the linkup to prevent any residual leakage while attached to the station.

Despite the leaks, NASA officials said more than enough helium remains on board to ensure a safe return to Earth at the end of a normal-duration or even extended mission.

On June 14, NASA and Boeing teams pushed back the target undocking and landing date for the Starliner spacecraft from the International Space Station by four days. They shifted from June 18 to now no earlier than June 22.

The reason for the extended stay is in part due to a need to gather more information about the Starliner capsule with the benefit of having an astronaut crew assigned to study aspects of the spacecraft with additional detail.

The helium leaks are all located in the Starliner’s drum-shaped service module, which is discarded to burn up in the atmosphere before the crew capsule re-enters for landing. Thus, there is no possibility of post-flight analysis of the problems.

Voyager 1 is Back To Life, But For How Long?

NASA engineers have succeeded in breathing new life into Voyager 1, the spacecraft launched in 1977 and once again communicating after it went silent seven months ago. But now comes another challenge: Keeping Voyager 1 scientifically useful for as long as possible as it probes a realm where no spacecraft has gone before.

Voyager 1 and its twin, Voyager 2, are treasured at NASA not only because they have sent home astonishing images of the outer planets, but also because in their dotage, they are still doing science that can’t be readily duplicated.

They are now in interstellar space, far beyond the orbits of Neptune and Pluto. Voyager 1 is more than 15 billion miles from Earth and Voyager 2 nearly 13 billion miles. Both have passed the heliopause, where the “solar wind” of particles streaming from the sun terminates.

“They’re going someplace where we have nothing, we have no information,” NASA Deputy Administrator Pam Melroy said. “We don’t know anything about the interstellar medium. Is it a highly charged environment? Are there a lot of dust particles out there?”

Ed Stone, who guided the mission from 1972 until 2022, died on June 9. (Luis Sinco/Los Angeles Times/Getty Images)

Even as the Voyagers continue their journeys, engineers and scientists at the NASA Jet Propulsion Laboratory in Pasadena, Calif. are mourning the loss of Ed Stone, the scientist who guided the mission from 1972 until his retirement in 2022. Stone, a former director of JPL, died June 9 at the age of 88.

Voyager 1 has four scientific instruments still operational in this extended phase of its mission, but it suddenly ceased sending intelligible data on Nov. 14. A “tiger team” of engineers at JPL spent the ensuing months identifying the problem — a malfunctioning computer chip — and restoring communication.

What no one can change, though, is the mortality of a spacecraft with a limited power supply. Voyager 1 is running on fumes, or, more precisely, on the dwindling power from the radioactive decay of plutonium. The Voyagers use a radioisotope thermoelectric generator. But an RTG doesn’t last forever. Voyager 1 and Voyager 2 will eventually go silent as they continue to cruise the galaxy.

“At some point, we’ll have to start turning off the science instruments one by one,” project scientist Linda Spilker said. “Once we’re out of power, then we can no longer keep the spacecraft pointed at the Earth. And so [the Voyagers] will then continue on as what I like to think of as our silent ambassadors.”

In a sense, this is all a bonus because the primary mission for the two Voyagers was the exploration of the outer planets. Both visited Jupiter and Saturn, and Voyager 2 went on to Uranus and Neptune in what was known as the “Grand Tour” of the outer solar system, enabled by a rare orbital arrangement of the planets. The Voyagers delivered spectacular close-up images of the outer planets, and the mission ranks among NASA’s greatest achievements.

The gravitational slingshot from the planetary encounters sent Voyager 1 out of the elliptical plane of the solar system and did the same to Voyager 2 in a different direction.

About four years ago, Voyager 1 encountered something unexpected — a phenomenon scientists have dubbed a pressure front. Jamie Rankin, deputy project scientist, said the instruments on the spacecraft picked up a sudden change in the magnetic field of the interstellar environment, as well as a sudden increase in the density of particles.

What exactly caused this change remains unknown. But NASA scientists are eager to get all the data flowing normally again to see whether the pressure front is still detectable.

The 2024 AMSAT Field Day Rules

The AMSAT Field Day 2024 event is open to all Amateur Radio operators. Amateurs are to use the exchange as specified in ARRL rules for Field Day. The AMSAT competition is to encourage the use of all amateur satellites, both analog and digital. Note that no points will be credited for any contacts beyond the ONE allowed via each single-channel FM satellite. Operators are encouraged not to make any extra contacts via theses satellites (Ex: SO-50). CW contacts and digital contacts are worth three points as outlined below.

Analog Transponders

ARRL rules apply, except:

Each phone, CW, and digital segment ON EACH SATELLITE TRANSPONDER is considered to be a separate band.
CW and digital (FT-4, RTTY, PSK-31, etc.) contacts count THREE points each.
Stations may only count one (1) completed QSO on any single channel FM satellite. If a satellite has multiple modes such as V/u and L/s modes both turned on, one contact each is allowed. If the both ISS stations are operational, one QSO on each mode (1 phone and 1 digital), Contacts with the ISS crew will count for one contact if they are active. Greencube (1 digital).
The use of more than one transmitter at the same time on a single satellite transponder is prohibited.

Digital Transponders

Satellite digipeat QSO’s and APRS short-message contacts are worth three points each, but must be complete verified two-way exchanges. The one contact per FM satellite is not applied to digital transponders.

The use of terrestrial gateway stations or internet gateways (i.e. EchoLink, IRLP, etc.) to uplink/downlink is not allowed.

For ‘Store and Forward’ hamsats, each satellite is considered a separate band. Do not post “CQ” messages. Simply upload ONE greeting message to each satellite and download as many greeting messages as possible from each satellite. The subject of the uploaded file should be posted as Field Day Greetings, addressed to ALL. The purpose of this portion of the competition is to demonstrate digital satellite communications to other Field Day participants and observers. Do not reply to the Field Day Greetings addressed to ALL.

The following uploads and downloads count as three-point digital contacts.

(a) Upload of a satellite Field Day Greetings file (one per satellite).

(b) Download of Satellite Field Day Greetings files posted by other stations. Downloads of non-Field Day files or messages not addressed to ALL are not to be counted for the event. Save DIR listings and message files for later “proof of contact.”

You may make contacts with GreenCube, IO-117, and each one will count as 3 points as do other digital contacts.

Please note AMSAT uploaded messages do not count for QSO points under the ARRL rules.

Sample Satellite Field Day Greetings File:

KK5DO FD EL29 class 2A 20 participants

Note that the message stated the call, operating class, where they were located (the grid square) and how many operators were in attendance.

Operating Class

Stations operating portable and using emergency power (as per ARRL Field Day rules) are in a separate operating class from those at home connected to commercial power. On the report form simply check off Emergency or Commercial for the Power Source and be sure to specify your ARRL operating class (2A, 1C, etc.).

AND FINALLY…

Add photographs or other interesting information that can be used in an article for the Journal.

You will receive an e-mail back (within one or two days) from me when I receive your e-mail submission. If you do not receive a confirmation message, then I have not received your submission. Try sending it again or send it to my other e-mail address.

Certificates will be awarded for the first-place emergency power/portable station at the AMSAT General Meeting and Space Symposium in the fall of 2024. Certificates will also be awarded to the second and third place portable/emergency operation in addition to the first-place home station running on emergency power. A station submitting high, award-winning scores will be requested to send in dupe sheets for analog contacts and message listings for digital downloads.

You may have multiple rig difficulties, antenna failures, computer glitches, generator disasters, tropical storms, and there may even be satellite problems, but the goal is to test your ability to operate in an emergency situation. Try different gear. Demonstrate satellite operations to hams that don’t even know the HAMSATS exist. Test your equipment. Avoid making more than ONE contact via the FM-only voice HAMSATS or the ISS, and enjoy the event!

Satellite Shorts From All Over

+ The U.S. spacewalk 90 planned for Thursday, June 13 at the International Space Station did not proceed as scheduled due to a spacesuit discomfort issue. NASA astronauts Tracy C. Dyson and Matthew Dominick, KCØTOR, completed taking off their spacesuits about an hour before the crew was anticipated to exit the Quest airlock. With consideration to NASA’s Boeing Crew Flight Test and other spaceflight operations, the next spacewalk will be Monday, June 24, followed by another on Tuesday, July 2, as was previously planned. The June 24 spacewalk will focus on radio frequency group hardware removal, while the content of the July 2 spacewalk is under evaluation and will be shared as available. The crew members on the station are healthy, and spacesuits are functioning as expected.

AMSAT Deutschland e.V. and the Bochum Observatory are taking the positive experience of the anniversary conference in 2023 as an opportunity to inform AMSAT members and other space enthusiasts about current and future prospects for national and international space projects with a varied program. As the Radom is also the location of ESA’s education office in Germany (esero Germany), a goal is to make the symposium even more attractive in future and at the same time focus even more on current European space travel.

+ SpaceX’s enormous rocket took off again from South Texas on June 6, this time with the sole goal of bringing both the booster and ship softly back to Earth in (roughly) single pieces. An on-time launch of the world’s most powerful rocket delivered excitement from start to finish. Despite an engine out on launch and landing (with 33 engines total, Superheavy doesn’t care), the first stage was able to complete a nominal ascent, hot-staging, temporary hot-staging ring jettison, boost back, and landing burn—all with enough precision that previously deployed buoy cams were able to capture its soft splashdown.

+ Russian cosmonaut and ISS commander Oleg Konenko became the first person to reach 1,000 cumulative days in space as of June 4. The milestone comes amid his fifth flight to space and during his third stint as the commander of the ISS. His most recent trip to the orbiting laboratory began with a launch aboard the Soyuz MS-24 spacecraft on Sept. 15, 2023, alongside cosmonaut Nikolai Chub and NASA astronaut Loral O’Hara, KI5TOM. He’s scheduled to return with Chub and NASA astronaut Tracy Dyson in September 2024. [ANS thanks Spaceflight Now for the above information.]
