ARISS Marks 40th Anniversary of STS-9 with Special Slow Scan Television Event

In a collaborative effort spanning ARISS teams worldwide, a special Slow Scan Television (SSTV) event is currently underway to mark the 40th Anniversary of NASA Space Shuttle mission STS-9. SSTV transmissions from the International Space Station (ISS) are being broadcast on 145.800 MHz using the PD120 format. The scheduled times for the event are from December 16 at 10:15 UTC | 5:15 AM ET through December 19 around 1800 UTC | 1:00 PM ET.

On November 28, 1983, the Space Shuttle Columbia carried Owen Garriott, W5LFL (SK), into orbit. He was equipped with a specially customized Motorola MX-340 two-meter handheld radio and an antenna attached to the shuttle’s window. The first amateur radio contact from space took place shortly before crossing the west coast on December 1, 1983, when Columbia executed a roll maneuver exposing the antenna toward Earth. W5LFL began calling CQ, and at 02:38 UTC, Lance Collister, WA1JXN, in Frenchtown, MT, answered the call, marking the first amateur radio QSO with a human in space.

A flurry of QSOs followed over the next several days before Columbia returned to Earth on December 8th. Notable amateur operators in the log included Senator Barry Goldwater, K7UGA, and King Hussein of Jordan, JY1. Slow Scan Television has also been an integral part of Amateur Radio in Human Spaceflight since its early days, with Tony England, WØORE, paving the way by sending ten images via Slow Scan Television on Space Shuttle Challenger mission STS-51F in the summer of 1985.

Answers to your Frequently Asked Questions (FAQ) about this ISS Slow Scan Television Event, such as how to decode SSTV images and track the ISS, can be found at https://www.spaceflightsoftware.com/ARISS_SSTV/faq.php.

HADES-D Satellite: Successful Telecommand Response and FM Repeater Tests Ongoing

The HADES-D satellite, launched aboard SpaceX’s Transporter-9 (TR-9) mission on November 11, 2023, has successfully completed a month in orbit. AMSAT-EA reports that, following its separation from the ION SCV-013 Orbital Transfer Vehicle two weeks ago, HADES-D is responding well to telecommands from the ground control station.

Current tests on the FM voice repeater show promising results, demonstrating its effectiveness. However, adjustments to the squelch level are under consideration due to the current configuration requiring increased power for activation. HADES-D’s health status has been confirmed through telemetry, CW, and FM voice beacon receptions from various Earth locations.

Telemetry signals in FSK, CW, and FM voice beacon, operating at 436.666 MHz downlink, transmit to Earth at 0.25 Watts. Demodulation and decoding software for satellite telemetry are available on AMSAT-EA’s website under the Project tab (https://www.amsat-ea.org/proyectos). The FM repeater, with a 40mW power output, may require a robust antenna for optimal receive performance.

Developed alongside the URESAT Antonio de Nebrija, both utilizing the pocketQubes 1.5P platform, HADES-D features advanced solar panels and increased processing capacity. These advancements enable the satellite to transmit telemetry and repeat signals at higher speeds. The incorporation of an FM transponder for voice communications also allows for message retransmission in FSK. Efforts are ongoing to confirm the final Two-Line Elements for streamlined operations.

WRC-23 Reaches Acceptable Conclusion on 23-Centimeter Issue

The International Telecommunication Union (ITU) World Radiocommunication Conference 2023 (WRC-23) continues through December 15, 2023, in Dubai, United Arab Emirates (UAE).

The International Amateur Radio Union (IARU)’s primary effort focused on Agenda Item 9.1 topic b to address amateur use of the 23-centimeter band and co-frequency use by several radionavigation satellite service (RNSS) systems in the 1240 – 1300 MHz band.

IARU’s work that began four years ago with a preparatory study in the ITU Radiocommunication Sector (ITU-R) to address this agenda item has finally come to a close. Our concerted engagement in the ITU-R working parties, study groups, and WRC preparatory meetings ensured that the amateur services were properly represented during the development of two published ITU-R reports: M.2513 and M.2532. An ITU-R Recommendation, M.2164, followed these, which formed the basis for the discussions at WRC-23.

During the WRC-23 deliberations, strong positions were expressed by all parties involved.

The result is a well-supported compromise for a footnote in the Radio Regulations regarding amateur and amateur satellite service operation in the 1240 -1300 MHz range. The footnote reminds administrations and amateurs of the need to protect the primary RNSS from interference, and it provides guidance for administrations to allow both services to continue to operate in this portion of the spectrum.

Administrations are the bodies that govern amateur radio in their respective countries, such as the Federal Communications Commission (FCC) in the United States.

The Conference Plenary compromise was formally adopted on December 8 and is not subject to further consideration during the final week of WRC-23. The IARU team continues its work on other WRC issues, including developing agendas for future conferences.

IARU President Tim Ellam, VE6SH, noted, “This is a very good result for the amateur services. The decision reached at WRC-23 on this agenda item makes no change to the table of allocations nor incorporates by reference M.2164 into the Radio Regulations. The addition of a footnote that provides guidance to administrations in the event of interference to the RNSS is a good regulatory outcome for amateurs and the primary users of this band.”

The WRC also agreed to suppress Resolution 774, which closes the issue and satisfies the agenda item. Read more in ARRL News at https://www.arrl.org/news/wrc-23-reaches-acceptable-conclusion-on-23-centimeter-issue

How the 18th Space Defense Squadron Averts Catastrophe at 17,000 Miles Per Hour

In the vast expanse of space, where countless manmade objects hurtle through Low Earth Orbit at speeds exceeding 17,000 miles per hour, a dedicated group of guardians stands watch to prevent potential collisions that could disrupt crucial communication, navigation, and scientific satellites. The 18th Space Defense Squadron (SDS), part of the Space Force, operates from its headquarters at Vandenberg Space Force Base, California, employing advanced technology and surveillance systems to track and identify potential collision risks in real-time.

The 18th SDS, often referred to as the “lighthouse of space,” utilizes the U.S. Space Surveillance Network (SSN) to monitor over 45,000 objects in Earth’s orbit. Ground-based sensors, including the Ground-Based Electro-Optical Deep Space Surveillance System, capture rapid digital photos of the night sky, revealing satellites as tiny streaks. Computers analyze these streaks to calculate the satellites’ positions, providing vital data for collision risk assessments, as explained in a recent press release from the Space Operations Command.

Key components of the SSN include ground-based radar systems such as the AN/FPS-85 and AN/FYS-3 Phased Array Radars, capable of tracking hundreds of targets simultaneously. The ‘Space Fence,’ located in the Marshall Islands, employs an array system that broadcasts constant bands of energy, tracking objects passing through its coverage. On-orbit platforms like the Space-Based Space Surveillance satellite ensure year-round tracking above earthly obstructions like weather and daylight.

Maintaining an ever-growing catalog of space objects on Space-Track.org, the 18th SDS collaborates with its counterpart, the 19th SDS, to predict satellite trajectories and avert potential collisions. In the crowded expanse of low Earth orbit, the squadron remains vigilant, recognizing the heightened risk posed by unexpected satellite fragments that could lead to disastrous collisions.

Space Operations Command (SpOC) recently outlined four categories of fragmentation events: anomalous debris-causing events, breakup events, collisions, and mission-related events. Anomalous events occur due to factors like corrosion or fatigue, leading to slow-speed fragment dispersal. Breakup events, generating large amounts of rapidly spreading debris, can be unintentional or intentional, as seen in anti-satellite missile tests. Collisions, exemplified by the 2009 incident involving a Russian military satellite and a commercial Iridium satellite, prompt heightened awareness and response. Mission-related events involve the fragmentation of payloads or unintentional separation of non-payload components.

Members of the 18th SDS remain vigilant for changes in orbital parameters, indicators of potential satellite stress or gas release, which could precede fragmentation events. Specialized software assists in tracking satellite trajectories and determining the origin and trajectory of debris in case of fragmentation. Timely warnings to affected satellite operators enable them to make necessary adjustments, minimizing collision risks.

Despite the 18th SDS’s capabilities, over a million objects under 10 cm remain untrackable but pose significant collision threats. The act of maneuvering to avoid collisions consumes satellite fuel and shortens their lifespan. Recognizing the limitations, a recent call by the research group RAND advocates for an international space traffic management system (STM) to enhance coordination and communication among satellite operators.

The current state of managing space objects is described by RAND researchers as “informal, ad hoc, and often ill-coordinated,” approaching a tipping point. Urging proactive governance structures, the researchers emphasize the need for the space community to build systems ensuring the safety and sustainability of critical space assets, services, and activities before a crisis necessitates action.

CubeSat Technology and 3D Printing Combine for Emergency Broadband in Disaster Zones

Researchers from the Centre Tecnològic de Telecomunicacions de Catalunya (CTTC), the University of Luxembourg, and the Universitat Oberta de Catalunya (UOC) have developed a nanosatellite technology aimed at delivering swift emergency broadband connectivity to disaster-stricken regions. This innovative solution combines CubeSat technology with 3D printing, allowing for rapid deployment to enhance communication for emergency services in complex situations.

Professor Carlos Monzo Sánchez of the Universitat Oberta de Catalunya emphasizes the project’s significance, stating, “Our project provides a solution that means a communications network to provide help in emergency situations can be established quickly.” The core technology is the CubeSat standard for nanosatellites, known for their cost-effectiveness and small size, manufactured on a 3D printer in just 90 minutes.

The CubeSats are then elevated above disaster zones using balloons, utilizing LoRa (low-power long-range radio) communication with the ground. Raúl Parada, a researcher at CTTC and the paper’s first author, explains, “Our solution enables communication over long distances and provides a scalable system for a large number of users that is reusable anywhere and at any time.”

The team’s prototypes leverage the Semtech SX1278 LoRa transceiver, connected to a simple metal ruler antenna. The 1U CubeSat, housing the transceiver, is equipped with a sensor package comprising a Bosch Sensortec BME280 environmental sensor, a TDK InvenSense MPU-9250 inertial measurement unit (IMU), a Hanwei MQ-135 air quality sensor, and a Roithner LaserTechnik GUVA-S12SD ultraviolet light sensor. These sensors are linked to an Arduino Nano microcontroller, with a GPS receiver added later to facilitate satellite recovery.

Emphasizing the practicality of their design, Monzo explains, “Our solution is designed to provide a rapid service in complex scenarios, and as such, we have prioritized its ease of deployment over its use as a telecommunications solution in normal situations.” The researchers aim to refine the infrastructure further, focusing on minimizing deployment times and ensuring adaptability to a wide range of situations.

The team’s work has been published in the journal Aerospace under open-access terms, marking a significant stride in leveraging technology to enhance emergency response capabilities in disaster-stricken areas.

Satellite Shorts From All Over

+ AO-73 (FUNcube-1), managed by AMSAT-UK and AMSAT-NL, has reactivated its transponder after a meticulous year of battery management. Launched a decade ago, the satellite faced challenges with its battery struggling to reach the nominal 8.3V charge. Recent efforts, including strategic transmitter shutdowns during eclipse periods, have improved the situation. The battery voltage now varies between 8.13V in sunlight and 7.8V at the end of an eclipse, a significant improvement. AO-73 is currently transmitting low-power BPSK telemetry on 145.935MHz, featuring an inverting mode U/V transponder uplink ranging from 435.130 to 435.150 MHz, with a downlink set at 145.970 to 145.950 MHz. The satellite maintains a high spin rate of approximately 30 rpm, requiring manual tuning for the 70 cm input due to the receiver’s temperature drift. This development reopens exciting opportunities for radio operators interested in exploring AO-73’s capabilities after its temporary hiatus. (ANS thanks David Bowan, G0MRF, AMSAT-UK for the above information)

+ NASA’s Voyager 1 probe, now in interstellar space, is experiencing a communication glitch, preventing the transmission of scientific or systems data. The 46-year-old spacecraft can receive commands, but its flight data system (FDS) is no longer communicating as expected with the telecommunications unit (TMU). The FDS compiles data into a package for transmission, but it’s currently stuck in a repeating pattern of ones and zeros. Voyager’s engineering team is investigating, but a solution may take weeks. The spacecraft’s age and technology from the 1970s present unique challenges, and previous malfunctions required creative software workarounds. Despite past issues, finding solutions for Voyager’s challenges is a slow process, involving consultation of decades-old documents. (ANS thanks Josh Dinner, Content Manager & Writer, Space.com, for the above information)

+ Blue Origin is set to resume New Shepard suborbital launches no earlier than December 18th, marking the vehicle’s first potential flight in over 15 months. The uncrewed mission, NS-24, will follow a mishap in September 2022 when a structural failure in the BE-3PM engine led to a capsule landing safely while the propulsion module crashed. The Federal Aviation Administration closed its investigation in September 2023, outlining 21 corrective actions for Blue Origin, including technical modifications and organizational changes. The delay in resuming flights prompted speculation about the company’s priorities, but it has since won a NASA contract for a lunar lander, introduced an orbital transfer vehicle, and progressed with the New Glenn orbital launch vehicle and Orbital Reef space station projects. During this hiatus, Virgin Galactic began commercial service with its SpaceShipTwo, VSS Unity, but announced plans to shift to quarterly flights in 2024 and eventually halt operations to focus on new suborbital vehicles. (ANS thanks Jeff Foust, writing for SpaceNews, for the above information)

+ NASA astronaut Frank Rubio grew tomatoes in space using hydroponic techniques to demonstrate space agricultural methods on the International Space Station (ISS). After harvesting one of the first tomatoes grown in space, Rubio misplaced it during a public event with school kids, sparking a humorous search on the ISS. In the microgravity environment, anything unanchored can float away, and despite spending hours searching, Rubio never found the tomato. The mystery ended when the remaining ISS crew announced they had located the tomato, clearing Rubio of suspicions that he had eaten it. Rubio’s historic mission on the ISS, lasting over a year, set a record for the longest a US astronaut has spent in microgravity, initially planned for six months.

ISS Resupply Will Interrupt ARISS Activity

NASA will provide live launch and docking coverage of the Roscosmos Progress 86 cargo spacecraft carrying about three tons of food, fuel, and supplies for the Expedition 70 crew aboard the International Space Station.

The unpiloted spacecraft is scheduled to launch on Friday, December 1,2023 at 09:25 UTC (4:25 A.M. EST) on a Soyuz rocket from the Baikonur Cosmodrome in Kazakhstan.

NASA coverage will begin at 4 A.M. on the NASA+ streaming service via the web <https://plus.nasa.gov/> or the NASA app <https://www.nasa.gov/connect/apps.html>.

The Progress spacecraft will be placed into a two-day, 34-orbit journey to the station, leading to an automatic docking to the Poisk module at 6:14 a.m. Sunday, Dec. 3. Coverage of rendezvous and docking will begin at 5:30 a.m. on NASA Television and the agency’s website. As always, all amateur radio activity aboard the ISS is suspended during docking maneuvers.

The spacecraft will remain at the orbiting laboratory for approximately six months, then undock for a destructive but safe re-entry into Earth’s atmosphere to dispose of trash loaded by the crew.

ISS SSTV Event December 7-8, 2023

Russian cosmonauts on the International Space Station (ISS) are planning to transmit Slow Scan TV (SSTV) images on 145.800 MHz FM probably using the SSTV mode PD-120.

The transmissions are part of the Moscow Aviation Institute SSTV experiment (MAI-75) and will be made from the amateur radio station RS0ISS in the Russian ISS Service module (Zvezda) using a Kenwood TM-D710E transceiver. It appears the theme for this session will highlight one of MAI’s cosmonaut graduates – Yuri Usachov. Currently scheduled days and times are:

Thu 2023-12-07 08:55 UTC to 14:25 UTC
Fri 2023-12-08 08:15 UTC to 14:10 UTC

Days and times are subject to change due to the operational requirements of the ISS.

Reminder – No ARISS award will be available for this session since it is not transmitted globally.

Changes to AMSAT-NA TLE Distribution for December 1, 2023

The following satellite has been removed from this week’s AMSAT-NA TLE distribution:

NEUDOSE NORAD Cat ID 56315 Decayed from orbit on or about 28 November 2023

The following satellites have been added to this week’s AMSAT-NA TLE distribution:

HADES-D NORAD Cat ID 58294 IARU coordinated downlink on 436.666 MHz
VERONIKA NORAD Cat ID 58261 IARU coordinated downlink on 436.680 MHz
KAFASAT NORAD Cat ID 58317 IARU coordinated downlinks 435.835 MHz and 2404.400 MHz

AMSAT thanks Nico Janssen for positively identifying these spacecraft and associating them with object numbers.

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 crossband repeater continues to be active (145.990 MHz up {PL 67} & 437.800 MHz down). If any crewmember is so inclined, all they have to do is pick up the microphone, raise the volume up, and talk on the crossband repeater. So give a listen, you just never know.

As always, if there is an EVA, a docking, or an undocking; the ARISS radios are turned off as part of the safety protocol.

Note, all times are approximate. It is recommended that you do your own orbital prediction or start listening about 10 minutes before the listed time.

The latest information on the operation mode can be found at https://www.ariss.org/current-status-of-iss-stations.html

Upcoming Satellite Operations

None scheduled at this time.

A growing number of satellite rovers are currently engaged in sharing their grid square activations on https://hams.at. By visiting the website, you gain easy access to comprehensive information about the operators responsible for activating specific grid squares. Additionally, you have the ability to assess the match score between yourself and a particular rover for a given pass, while also being able to identify the upcoming satellite passes that are accessible from your location.

Hamfests, Conventions, Maker Faires, and Other Events

AMSAT Ambassadors provide presentations, demonstrate communicating through amateur satellites, and host information tables at club meetings, hamfests, conventions, maker faires, and other events.

AMSAT Ambassador Clint Bradford, K6LCS, says, “Think a 75-minute presentation on “working the easy satellites” would be appropriate for your club or event? Let me know by emailing me at k6lcsclint (at) gmail (dot) com or calling me at 909-999-SATS (7287)!” Clint has NEVER given the exact same show twice: EACH of the 150+ presentations so far has been customized/tailored to their audiences.

Satellite Shorts From All Over

+ Eirsat-11 was successfully launched on Friday, December 1, 2023 from Florida aboard a Space X ride. On the first pass over Europe EIRSAT-1 was almost 10 minutes late on the preliminary TLE set and almost 4 minutes early on the projected TLE set. The launch team will try to develop better parameters. Since this was a classified launch, TLEs may not be published by he usual sources, so the team will have to develop its own TLE set. [ANS thanks Nico Janssen, PA0DLO, for the above information.]

+ A fascinating article describes the development of the CubeSat standard by AMSAT member Bob Twiggs, KE6QMD, and co-inventor Jordi Puig-Suari, an aerospace engineering professor at California Polytechnic State University. Searching for a way to simplify the projects—and cut out build time — Twiggs thought, “What if we made [the satellite] a cube and put solar cells on all sides so no matter which way it rotated, it was going to get charged?” With some spare solar cells from NASA’s Jet Propulsion Laboratory, he went down to a local shop and found a 4 X 4 X 4-in. transparent box. It was also around that time—in 1999—that an infamous error caught Twiggs’ attention. That year a mix-up between Imperial and metric units by a Lockheed Martin engineering team caused NASA’s Mars Climate Orbiter to burn up in the red planet’s atmosphere, ending the mission early. “I said, ‘It’s about time students learn metric,’” he says. “I wonder what this [4-in. box] is in metric? Well, it turned out to be just almost 10 cm.” Read the entire article at https://tinyurl.com/ANS-337-Twiggs. [ANS thanks Aviation Week Network for the above information.]

+ An innovative experiment flying aboard NASA’s Psyche mission just hit its first major milestone by successfully carrying out the most distant demonstration of laser communications. The tech demo could one day help NASA missions probe deeper into space and uncover more discoveries about the origin of the universe. The experiment beamed a laser encoded with data from far beyond the moon for the first time. The test data was sent from nearly 10 million miles (16 million kilometers) away and reached the Hale Telescope at the California Institute of Technology’s Palomar Observatory in Pasadena, California.
