ARISS Announces 40th Anniversary Conference at NASA Kennedy Space Center

In recognition of the positive impact of amateur radio on human spaceflight, an exciting celebration is on the horizon. Space enthusiasts, astronauts, educators, and amateur radio operators are coming together to commemorate the 40th Anniversary of a groundbreaking event. This pivotal moment occurred when Astronaut Owen Garriott, W5LFL, pioneered amateur radio communication from space during his mission on the STS-9 Space Shuttle Columbia flight, spanning from November 28 to December 8, 1983.

Astronaut Garriott, during his free time on the STS-9 mission, became the first person in space to communicate with amateur radio operators on the ground. Moreover, his radio signals were the first ever to be directly heard from space by the public, using nothing more than simple FM receivers and scanners. This milestone forever changed astronaut communication, opening up interaction with amateur radio operators and the public, who previously had limited access to speak with spacefarers.

Over the past four decades, Garriott’s pioneering mission has paved the way for countless interactions between astronauts and Earthlings through the medium of amateur radio, on the Space Shuttle, Mir space station, and the International Space Station. Over a million people on Earth have directly participated in these astronaut radio contact engagements, with a particular emphasis on educational youth contacts. This initiative, coupled with pre-contact education programs, has ignited the spark of curiosity and interest in Science, Technology, Engineering, and Math (STEM) among youth worldwide.

As the 40th anniversary of human spaceflight amateur radio approaches, the ARISS (Amateur Radio on the International Space Station) team is inviting volunteer teams, astronauts, space agency officials, educators, and space and amateur radio enthusiasts to join them in commemorating and celebrating this inspirational journey. The event, titled the “40th Anniversary Celebration of the Positive Impact of Amateur Radio on Human Spaceflight” is scheduled to take place from February 22 to 24, 2024, at the Center for Space Education: Astronauts Memorial Foundation, located adjacent to the NASA Kennedy Space Center Visitors Center in Florida.

The conference promises an array of engaging activities, including tours of the NASA Kennedy Space Center Visitors Center, exhibits on human spaceflight amateur radio, networking sessions, STEM education demonstrations, and two days filled with astronaut panel sessions. Attendees can also look forward to presentations by STEM career alumni and recollections shared by educators and volunteer team alumni who supported hardware development, flight operations, and youth STEM engagement for the Shuttle, Mir, and ISS missions.

In a special request, the organizers of the event are seeking the stories of students who participated in the SAREX (Shuttle/Space Amateur Radio Experiment), Mir, and ARISS programs over the last 40 years and have since pursued careers in STEM. These students or those who know them are encouraged to get in touch with the organizers through in-person participation, video submissions, emails, or letters. Additionally, educator testimonials regarding the impact of these programs in schools are welcomed.

Amateur Radio on the International Space Station (ARISS) is a collaborative initiative between international amateur radio societies and space agencies supporting the International Space Station (ISS). In the United States, sponsors include the American Radio Relay League (ARRL), Amateur Radio Digital Communications (ARDC), Radio Amateur Satellite Corporation (AMSAT), NASA’s Space Communications and Navigation program (SCaN), and the ISS National Lab—Space Station Explorers. The primary goal of ARISS is to foster exploration of science, technology, engineering, the arts, and mathematics topics through organized scheduled contacts between ISS crew members and students via amateur radio. These contacts are accompanied by hands-on learning activities related to space, space technologies, and amateur radio.

For registration and special event pricing at local hotels for the 40th Anniversary Conference, visit the event website at https://www.ariss.org and select the “40th Anniversary” tab.

Upcoming International Space Station Slow Scan TV Transmission Test

The International Space Station (ISS) is set to conduct a Slow Scan Television (SSTV) transmission test between October 27 and November 1, 2023. The test will serve to verify the performance of replacement SSTV equipment onboard the station. However, the test will be divided into two windows due to an Extra-Vehicular Activity (EVA) taking place during that time frame.

The first window for SSTV transmissions will open on Friday, October 27, at 12:15 UTC and will run until Sunday, October 29, at 18:50 UTC. The second window will begin on Tuesday, October 31, at 10:05 UTC and conclude on Wednesday, November 1, at 18:10 UTC. During these windows, the SSTV transmissions will take place on 145.800 MHz using the PD120 format.

It’s important to note that, similar to the earlier October test, the SSTV transmissions may not be active at all times within the specified windows. Therefore, enthusiasts and radio operators eager to capture these images should monitor the frequencies and times closely.

The ARISS (Amateur Radio on the International Space Station) SSTV gallery will be available for individuals to share the images they receive. The gallery can be accessed at https://www.spaceflightsoftware.com/ARISS_SSTV/index.php. For more information on the SSTV images transmitted from the ISS, you can visit the Gallery Website. This website will showcase some of the best SSTV images received during the test period.

No ARISS SSTV awards will be given for this event through the https://ariss.pzk.org.pl/sstv/ website. Stay tuned for further updates and don’t miss the chance to participate in this unique opportunity to capture images from space. For official updates and notifications related to the SSTV test, individuals are encouraged to follow ARISS on Twitter (@ARISS_Intl).

ISRO’s Gaganyaan Successful Test Flight Sets Stage for Crewed Space Mission

India’s space agency, the Indian Space Research Organization (ISRO), has taken a significant step forward in its ambitious Gaganyaan project by successfully conducting the first in a series of test flights. The project aims to send astronauts into space by 2025, making India the fourth country, after the Soviet Union, the United States, and China, to achieve this milestone.

The Gaganyaan spacecraft took to the skies at 10:00 local time (04:30 UTC) on Saturday from the Sriharikota launch site. Notably, this was the second attempt on the same day, as the first launch was put on hold just five seconds before its scheduled liftoff.

The primary objective of this test flight, known as the Flight Test Vehicle Abort Mission-1 (TV-D1), was to ascertain the spacecraft’s ability to safely rescue the crew in the event of a rocket malfunction. This “crew escape system (CES),” a critical component, had to prove its effectiveness during the test.

S Somanath, the Chairman of ISRO, announced the success of the mission, eliciting cheers and applause from his colleagues. The positive outcome of this test flight now paves the way for a series of unmanned missions, including sending a robot into space next year.

The Gaganyaan project, named after the Sanskrit word for “craft” or “vehicle to the sky,” has been developed at a cost of 90 billion rupees ($1 billion; £897 million). Its mission objective is to send a crew of three astronauts into low-Earth orbit, circling at an altitude of 400 kilometers (248 miles), for a duration of three days. Success in this endeavor will position India alongside the elite spacefaring nations.

However, before embarking on this monumental mission, ISRO needed to confirm the safe return of the human-carrying capsule. This crucial safety aspect was addressed in the TV-D1 test flight, where the ability to ensure the crew’s safety by moving them at least 2 kilometers (1.2 miles) away from the rocket in case of an emergency was demonstrated.

As part of the post-launch procedure, a series of parachutes were deployed to guide the module safely to the waters of the Bay of Bengal, approximately 10 kilometers from the Sriharikota coast. The Indian navy, with a ship and a team of divers, was prepared to recover the module and return it to shore.

The Gaganyaan test vehicle, equipped with cameras and instruments, collected valuable data and imagery during the mission. ISRO expects that this data will aid in conducting further tests and preparing for the final Gaganyaan mission.

With the successful completion of this test, ISRO is set to send a humanoid robot, named Vyommitra (Sanskrit for “space friend”), into space within an unmanned Gaganyaan spacecraft next year. The agency has also been diligently preparing Indian air force pilots, selected to be part of the crew, by subjecting them to a battery of tests, including extensive physical exercise, lab investigations, radiological assessments, clinical tests, and evaluations of their psychological fitness.

The Gaganyaan test flight generated substantial interest in India, even though it came more than half a century after astronauts from the Soviet Union and the United States embarked on journeys to low Earth orbit. China became the third nation to achieve spaceflight in 2003. India’s recent historic lunar landing near the Moon’s south pole in August 2023 and the launch of the Aditya-L1, its first Sun observation mission, have also elevated its space achievements.

In a bold vision for the future, India announced plans to establish a space station by 2035 and send an astronaut to the Moon by 2040, reaffirming its commitment to expanding its presence in space exploration.

NASA’s Voyager Spacecraft Receive Software Patch to Extend Their Mission

In an ongoing effort to extend the life of NASA’s Voyager 1 and Voyager 2 spacecraft, a team of dedicated engineers and scientists is working diligently to address the myriad challenges posed by the aging deep-space explorers. Launched nearly half a century ago, these iconic vessels have ventured into the far reaches of interstellar space, where their primary mission is to study cosmic rays, the magnetic field, and the plasma environment.

These missions, despite their age, continue to provide valuable scientific data. Nevertheless, as the years have gone by, the Voyagers have encountered several technical issues that necessitate creative solutions to ensure their continued functionality. Suzanne Dodd, Voyager project manager at NASA’s Jet Propulsion Laboratory, emphasized the importance of prolonging the mission’s longevity.

“These are measures that we’re trying to take to extend the life of the mission,” Dodd stated.

One of the primary challenges faced by the Voyager team is the lack of redundancy in the spacecraft. After more than four decades in space, the Voyagers no longer possess backup systems, meaning that a failure of a single component could jeopardize the entire mission.

“Everything on both spacecraft is single-string,” Dodd explained. “There are not any backup capabilities left. In some cases, we powered off stuff to save power, just to keep the instruments on.”

To address recent issues and ensure the continued success of the missions, NASA has taken innovative approaches. Ground controllers at JPL recently uplinked a software patch to Voyager 2, as a test before deploying the same patch to Voyager 1. The patch aims to rectify a computer issue that had persisted since 2022, where the Voyager 1 computer responsible for orienting the spacecraft was sending garbled status reports.

Furthermore, engineers have developed a new strategy for operating the spacecraft’s thrusters. These thrusters are essential for keeping the main antenna on each probe pointed at Earth, and there is a buildup of propellant residue in the narrow lines that feed hydrazine fuel to the thrusters. While this approach may result in occasional data loss, it will significantly extend the overall mission by preventing the complete blockage of the propellant inlet tubes.

“These two spacecraft are still operating, still returning uniquely valuable science data, and every extra day we get data back is a blessing,” Dodd emphasized.

Another pressing issue is the spacecraft’s declining power levels, as they rely on nuclear batteries that gradually produce less electricity each year. The power situation is currently stable and predictable, but as the batteries continue to degrade, NASA anticipates having to deactivate Voyager’s science instruments one by one late in the decade. Once the transmitter’s power requirements exceed the available power, the mission will come to an end.

Nevertheless, the Voyagers continue to push the boundaries of space exploration. Both spacecraft are now in the realm of interstellar space, representing the farthest human-made objects from Earth. These pioneering missions have not only provided an invaluable wealth of scientific knowledge but have also become a testament to the ingenuity and resourcefulness of NASA’s engineering and science teams.

“If you only look at the power situation, the Voyagers should make it until 2030, and maybe slightly longer,” Dodd stated. “But there are a lot of other issues that could pop up and cause a mission to fail.”

With contact still maintained with the Voyagers, albeit with a small team, it is NASA’s hope that these venerable spacecraft will continue their journey and provide insights into the mysteries of the universe for years to come.

“They’ve overcome lots of issues, and the engineers have been very clever in overcoming those issues,” Dodd concluded. “I think the focus now is let’s get to 50 and have the biggest party we can.”

+ NASA has revealed that it has already processed 70.3 grams of rocks and dust collected by the OSIRIS-REx mission from asteroid Bennu. That means the mission has way exceeded its goal of bringing 60 grams of asteroid samples back to Earth — especially since NASA scientists have yet to open the primary sample container that made its way back to our planet in September. Apparently, they’re struggling to open the container and could not remove two of its 35 fasteners using the tools currently available to them. The scientists are processing the samples inside a specialized glovebox with a flow of nitrogen in order to keep them from being exposed to our atmosphere and any contaminants. They can’t just use any implement to break the container’s fasteners open either: The tool must fit inside the glovebox, and it also must not compromise the samples’ integrity. NASA has sealed the primary container sample for now, while it’s developing the procedure to be able to open it over the next few weeks. (ANS thanks Engadget for the above information)

+ SpaceX will launch four European navigation satellites for the ESA due to delays in European launcher development. The agreement entails two Falcon 9 launches in 2024, each carrying two Galileo navigation satellites, pending approval from the European Commission and EU member states. Europe’s preference was to use its own rockets, like Ariane 6 and Vega-C, but technical issues led them to seek SpaceX’s services. The ongoing conflict between Russia and Ukraine ruled out the use of Soyuz rockets. These Galileo satellites are crucial for maintaining an independent European global satellite navigation system, and they contain encrypted communication equipment for European military use. This marks the first time in 15 years that Galileo satellites will launch from outside Europe and the first instance of SpaceX launching European satellites with classified equipment. (ANS thanks TechCrunch for the above information)

SpaceX intends to reach 100 flights this year, requiring a significant acceleration in launch cadence. They aim to achieve approximately 12 flights per month in 2024. Most of these missions will be dedicated to the Starlink internet-satellite megaconstellation. While Falcon 9 and Falcon Heavy rockets have dominated SpaceX’s missions so far, they are working on their reusable Starship rocket for future exploration, with a second test flight pending approval from the U.S. Federal Aviation Administration. SpaceX aims for rapid hardware development through frequent test flights despite regulatory challenges. (ANS thanks Space.com for the above information)

AMSAT Board Appoints Officers, Hears Reports

The AMSAT Board of Directors met on Thursday, Oct. 19 in Dallas, Texas in advance of the annual meeting and Symposium.

Since Board members whose terms were expiring were all re-elected, the Board was as previously constituted. Frank Karnauskas was welcomed as the new Alternate Board member.

+ All officers were re-appointed by acclamation:
    President — Robert Bankston, KE4AL, Dothan, AL
    Executive Vice President — Paul Stoetzer, N8HM, Washington, DC
    Vice President – Engineering — Jerry Buxton, N0JY, Granbury, TX
    Vice President – Operations — Drew Glasbrenner, KO4MA, Brooksville, FL
    Vice President – Educational Relations — Alan Johnston, KU2Y, Philadelphia, PA
    Vice President – Development — Frank Karnauskas, N1UW, Tucson, AZ
    Treasurer — Steve Belter, N9IP, West Lafayette, IN
    Secretary — Jeff Davis, KE9V, Yorktown, IN

+ President Robert Bankston gave his President’s Report. His focus was on improving transparency and accountability between AMSAT leadership and membership. This would include better reporting of finances, better standards for publishing our accomplishments, more attention to Member Services for member satisfaction, and redesign of the AMSAT website.

+ Treasurer Steve Belter was not in attendance, but the Treasurer’s Report was given on his behalf. The financial status of the organization is healthy.

+ Alan Johnston, Vice President – Educational Relations, reported that the CubeSat Simulators are getting good use in the amateur community, as well as in universities and high schools. The Simulator circuit boards have been selling well, and the fully built loaners are circulating constantly. An upgraded Simulator board, v.2, is in beta, and testers will be recruited from among builders of version 1. A new v.2 kit should become available next year.

+ The engineering report by Jerry Buxton, Vice President – Engineering, and Jonathan Brandenburg, KF5IDY, Assistant Vice President – Engineering. The engineering team now consists of more than 35 volunteers, each working 4 to 5 hours per week, on various projects for Fox-Plus, GOLF, ASCENT, and other related efforts. Recruiting of engineering volunteers is ongoing.
   Engineering challenges include supply chain problems and inflationary pressures. As technology advances quickly, some components become unavailable in the space between planning and construction. Export Administration Regulations (EAR) make international cooperation difficult.
   The GOLF (Greater Orbit, Larger Footprint) program was approved in 2017 as an incremental development path for return to High Earth Orbit (HEO). Applications for the first two satellites in this program, GOLF-TEE and GOLF-1, have both been accepted by NASA. The satellites are under construction, and the first will be delivered to NASA in late 2025, but there is no time frame for launch at this time.
   ASCENT (Advanced Satellite Communication and Exploration of New Technology) allows a “sandbox” for future satellite systems to be explored for eventual flight. Some of these projects are being incorporated into GOLF, including the deployable solar panels and the 3U cubesat structure.
   Fox-Plus, a 1U cubesat, is currently under construction utilizing the Linear Transponder Module similar to those that have been supplied to partners such as HuskySat and MESAT-1. The first Fox-Plus satellite will be completed no earlier than late 2024, with no time frame for launch at this time.

+ Vice President – Operations, Drew Glasbrenner, gave a rundown on satellites in orbit. We have a number of old satellites that keep chugging along, and the Operations team manages these resources as possible.

+ Vice President – Development, Frank Karnauskas, reported on plans to celebrate the 50th anniversary of AO-07 and the publicity surrounding it. There was also discussion of the AMSAT News Service bulletins and how they are distributed.

+ The IT report focused on the availability of @amsat.org email accounts. Costs of maintaining this service have increased immensely, and there have been many problems with spam filters crushing mail sent through this service.

+ Board Member Bruce Paige, KK5DO, reported on AMSAT Field Day and the awards programs. The AMSAT Store, reached through the amsat.org website, continues to do a brisk business with the SatPC32 tracking program being the best seller.

+ Export Control and Economic Sanctions Compliance Training was the last item on the agenda. President Bankston briefed the Board on current legal requirements.

AMSAT Board Discusses Policies and Procedures

President Robert Bankston reconvened the Board of Directors on Friday morning, Oct. 20. Bankston opened with a discussion of AMSAT’s policies and procedures, specifically the financial policies and procedures.

Discussion ensued regarding communicating information regarding Engineering projects and a public release of schedules. In some cases, legal agreements preclude release of specific launch information.

Discussion also continued regarding budgeting procedures for Engineering projects. Bankston compiled a list of further items for new business to discuss by the end of the meeting. Further new business discussion followed.

Paul Stoetzer raised the issue of a document repository to manage corporate documents for improving management and communication. It was broadly agreed that AMSAT would seek a solution in concert with the IT team.

Drew Glasbrenner was recognized to discuss a potential updated satellite tracking software.

A concern was raised that more senior AMSAT leadership should attend various conferences and events. It was agreed that there would be an increase in the amount budgeted for attendance at conferences in the 2024 Budget.

There was discussion of allocating funds for services would be contracted for user services, since AMSAT no longer has any employees.

A discussion also ensued on the AMSAT IP Policy. It was agreed that ideas for updating it would be developed and discussed in January.

Alternate Director Frank Karnauskas was recognized to discuss the need to define positions before filling them with volunteers. Some feel that positions need to be flexible in order to fit the willingness of volunteers.

Jerry Buxton opened discussion of ITU/FCC satellite authorization. He suggested obtaining external support to handle applications for satellite authorization. Drew Glasbrenner, as the AMSAT licensee, concurred. It was broadly agreed that it would be a benefit.

As the 50th anniversary of AO-7 draws near, plans are in the works for celebrating the anniversary.

Also discussed were potential locations for the 2024 Symposium. It was broadly agreed that Florida would be the location.

President Bankston mentioned his desire for re-engagement with our sister AMSATs around the world on satellite programs. The Board broadly agreed that the President should reach out to international AMSAT leadership and begin discussions.

The need was discussed for an updating of the Getting Started Guide and the need for a new editor.

President Bankston adjourned the meeting so that all could move on to attending the 41st AMSAT Symposium.

ESTCube-2 Fails to Deploy After Launch

A pair of payloads that were among 12 carried to orbit aboard the Arianespace-managed Vega VV23 flight failed to be deployed and likely burned up in the atmosphere still attached to the rocket’s upper stage.

The Vega VV23 flight was launched on October 9 at 01:36 UTC from the Guiana Space Centre in French Guiana. The rocket carried the THEOS-2 and FORMOSAT-7R/TRITON satellites as its primary payloads and ten smaller satellites as secondary payloads.

Following a successful launch, Arianespace published a press release confirming that the two primary payloads and eight of the ten secondary payloads had been deployed. However, the launch services provider added that “the separation of the last 2 cubesats is still to be confirmed.”

The launch utilized the Small Spacecraft Mission Service (SSMS) dispenser, which was designed by SAB Aerospace for Avio and is operated by Arianespace with the support of SAB Launch Services.

In an email sent by Arianespace to the affected teams that European Spaceflight has seen, the launch services provider explained that the ESTCube-2 and ANSER-Leader cubesats likely failed to separate from their respective deployers.

“Following the VEGA VV23 launch last Sunday, ARIANESPACE has now the strong suspicion that your satellites ESTCube-2 and ANSER-Leader were unfortunately not separated from their respective deployers,” said the email.

ESTcube-2, a 3U cubesat, was built by the Estonian Student Satellite Foundation and was supposed to carry a 9600bps digipeater similar to the former FalconSat-3, as well as several other amateur-related experiments.

Scientists Confirm Ancient Solar Storm

The largest known solar storm struck Earth more than 14,000 years ago, according to a new study of the growth rings in ancient trees. A similar storm striking Earth at present would likely knock out radio communications and satellites while causing widespread blackouts.

Carbon-14 (C14), the rarest carbon isotope on the planet, is primarily formed by cosmic rays emitted by the Sun through solar flares and coronal mass ejections interacting with the Earth’s atmosphere. The radioactive carbon isotope can eventually be absorbed by living organisms — like trees, plants and animals — throughout their lifetimes. The amount of C14 in certain organisms can reflect how abundant the isotope was in the atmosphere and, by extension, the amount of solar activity present at a given time.

A team of scientists discovered evidence of the storm by measuring the levels of C14 in rings of ancient pine trees that lived in the French Alps more than 14,000 years ago.

The researchers hypothesized that the abrupt spike was likely from a massive solar storm that was probably two times larger than all other major storms on record.

To verify their hypothesis, the researchers turned to ice cores, or cylinders of ice drilled from ice sheets and glaciers. They discovered that the C14 spike in the trees corresponded with an unusual concentration of beryllium-10 from between 14,301 and 14,292 years ago found in a Greenland ice core.

Tim Heaton, a professor of applied statistics at the University of Leeds and a co-author of the new study in the journal, Philosophical Transactions of the Royal Society A, noted that, “Extreme solar storms could have huge impacts on Earth. They would also create severe radiation risks to astronauts.”

Changes to AMSAT-NA TLE Distribution for Oct. 19

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. Elements in the TLE bulletin files are updated daily. TLE bulletin files are updated to add or remove satellites as necessary Thursday evenings around 2300 UTC, or more frequently if new high interest satellites are launched. More information may be found at https://www.amsat.org/keplerian-elements-resources/

The following satellites have been removed from this week’s AMSAT-NA TLE distribution:

Robusta 1B NORAD Cat ID 42792 Decayed from orbit on or about 16 October 2023
LO-87 LUSEX NORAD Cat ID 41557 Decayed from orbit on or about 19 October 2023

EVA Event Upcoming on ISS

Two NASA astronauts aboard the International Space Station will conduct a spacewalk Monday, Oct. 30, to complete maintenance activities at the orbital complex. 

Live coverage of the spacewalk begins at 6:30 a.m. EDT on NASA Television, the NASA app<https://www.nasa.gov/apps/>, and the agency’s website<https://www.nasa.gov/nasatv/>. The spacewalk is scheduled to begin about 8:05 a.m., and last about six-and-a-half hours.

NASA astronauts Jasmin Moghbeli, KI5WSL, and Loral O’Hara, KI5TOM, will exit the station’s Quest airlock to remove an electronics box called the Radio Frequency Group from a communications antenna on station. They also will replace one of 12 trundle bearing assemblies on a solar alpha rotary joint. The bearings enable the station’s solar arrays to rotate properly to track the Sun as the station orbits the Earth. When looking at the space station, the antenna is on the starboard (right side) truss, and the rotary joint is on the port, or left side.

U.S. spacewalk 89 will be the first for both Moghbeli and O’Hara. Moghbeli will serve as extravehicular activity crew member 1 and will wear a suit with red stripes. O’Hara will serve as extravehicular crew member 2 and will wear an unmarked suit.

Station managers continue planning for another spacewalk with O’Hara, as well as ESA (European Space Agency) astronaut Andreas Mogensen, to collect samples for analysis to see whether microorganisms may exist on the exterior of the orbital complex. That spacewalk, which now is U.S. spacewalk 90, has been postponed to no earlier than December.

+ Researchers at Purdue University’s College of Science found metals high in Earth’s stratosphere. Those metals are altering the chemistry in our planet’s atmosphere in ways we don’t fully understand, and may be causing damage to the earth’s protective ozone layer. The team concluded that the aerosols of over 20 chemical elements, including lithium, aluminum, copper, and lead, come from vapour boiling off of the surfaces of spent boosters and other space debris as it re-enters the atmosphere and burns up.

Estonia’s ESTCube-2 Digipeater in Orbit

ESTCube-2 is a 3U Cubesat largely designed and built by undergraduate students at the University of Tartu, Estonia. It was launched into sun-synchronous orbit as an auxiliary payload on the European Space Agency (ESA) Vega flight VV23 from the Guiana Space Centre at Kourou on October 8 at 01:36 UTC.
Among ESTCube-2’s several missions, it will conduct in-orbit signal strength mapping in the 2m and 70cm amateur bands, using periodical full band received signal strength indicator (RSSI) measurements in order to check how polluted these two radio amateur bands are in low Earth orbit.
In addition, a cross-band AX.25 digipeater mode will be used to allow amateur radio operators to use satellite for two-way digital communication. 9600 bps G3RUH AX.25 data uplink will be in 2m amateur band and transmission of digipeated packet in 70cm amateur radio band. Transmission speed and modulation will be the same as for uplink. [Similar to the now re-entered FalconSat-3.] There are plans to include periodic short audio announcements (similar to FOX-1) to indicate that the digipeater is active.
The high-speed communications system is a COTS transmitter system called HiSPiCO from IQ Technologies. It is used when downloading preselected Earth observation scientific camera full-resolution images using the 2.4 GHz amateur radio band. (See https://www.iq-spacecom.com/products/hispico for details.) Data will be downlinked using QPSK modulated up-to 1 Mbps data-rate signal. Software tools (e.g. GNU Radio, web browser- based) will be published before the satellite launch, in order to enable reception of high speed downlink by the amateur radio community.
The optional multi-station radio frequency ranging experiment will be used to determine satellite distance to Earth in order to improve accuracy of satellite orbit determination. For the experiment, the 70cm radio amateur band will be used in conjunction with four or more amateur ground stations using SDR-based equipment that can provide stable and accurate frequency and time measurements. The satellite downlink will be listened to from several ground stations at the same time.
To educate the next generation of radio amateurs, the satellite will transmit analog messages from space using an NBFM signal containing pre-recorded audio greetings. This activity will infrequently take place according to a schedule published publicly to schools and the AMSAT/HAM community. The transmitted signal will be received by participating Estonian secondary and high schools, using their own built radio antennas and SDR-based receiver systems. This activity is targeted primarily to promote amateur radio and satellite communication (and in general STEM fields) among the younger generation.
The Primary transceiver, shared with the amateur payloads, is using the 70 cm amateur radio band for uplink and downlink purposes. It will be used as the housekeeping beacon for a simple overview of the satellite status and as the main transceiver for receiving tele-commands and firmware upgrades. As well transmitting mission data, like telemetry from each subsystem (< 256 bytes per subsystem) and payload data, e.g. compressed, low resolution image thumbnails (~100 KiB), in AX.25 data packet format with 9600 baud data-rate with G3RUH modulated signal. The spacecraft will have experimental capability to change data-rate up-to 38600 baud using 2GFSK (or 4GFSK for testing) different modulation schemes. During the mission, it is planned to transmit a housekeeping telemetry beacon periodically (~1 KiB), typically once per minute, containing telemetry, health data packets from every subsystem.
The 70 cm amateur radio band downlink will be used to send Plasma brake tether experiment [link] and housekeeping data of the payload module such as temperature measurements, information about the attitude of satellite, energy production etc. (< 256 bytes).
After performing measurements of a material science experiment on corrosion resistant coating, the 70cm amateur radio band downlink will be used to transmit a very small amount of acquired sensor data (~ 200 B per day). The satellite will measure the electrical continuity of the coating material to determine its lifespan after exposure to atomic oxygen in LEO.
Proposing UHF 9k6 using GFSK/G3RUH modulation or 38k4 GFSK/4GFSK or, alternatively, FM voice downlinks, and on S Band downlink DQPSK modulation with 1 Mbps data-rate, downlinks on 435.800 MHz and 2425.000 MHz have been coordinated by the International Amateur Radio Union (IARU).
The Vega C VV23 launch plan was to put ESTCube-2 into a 555km Sun-Sychronous Orbit (SSO). Actual orbit parameters have yet to be confirmed. More info is at https://www.estcube.eu/projekt/ESTCube-2 and https://www.estcube.eu/blogi/Raadio

Changes to AMSAT-NA TLE Distribution for October 13, 2023

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 Thursday evenings around 2300 UTC, or more frequently if new high interest satellites are launched. More information may be found at https://www.amsat.org/keplerian-elements-resources/
The following satellites have been removed from this week’s AMSAT-NA TLE distribution:
AstroBioCubsat NORAD Cat ID 53107 Probably defunct, USSF no longer providing element sets.
Aurorasat NORAD Cat ID 56312 Decayed from orbit on or about 9 October 2023
Lightcube NORAD Cat ID 56314 Decayed from orbit on or about 12 October 2023

Comments on making general contacts
I have been seeing a lot of traffic on Facebook and I suspect on other social media sites with people asking why they are not hearing the crew make general contacts.  First off the crew is very busy on the ISS and they simply may not have the time to just pick up the microphone and talk.  Also, one needs to be aware of their normal daily schedule.  I have listed below the constraints that we at ARISS have to follow in order to schedule the school contacts.  Hopefully this will help you better schedule your opportunities.
Typical daily schedule
Wakeup to Workday start= 1.5 hours
Workday start to Workday end=12 hours
Workday end to Sleep= 2 hours
Sleep to wakeup= 8.5 hours
The crew’s usual waking period is 0730 – 1930 UTC. The most common times to find a crew member making casual periods are about one hour after waking and before sleeping, when they have personal time. They’re usually free most of the weekend, as well.
SSTV events are not that often.  So please check out https://www.ariss.org/ for the latest information or watch for the ARISS announcements.
And don’t forget that the packet system is active.
As always, if there is an EVA, a docking, or an undocking; the ARISS radios are turned off as part of the safety protocol.
