HADES-D Designated SO-121, Active For General Use

HADES-D satellite has been commissioned. After a trial period in which its behavior has been tested at the radioelectric, systems, and energy performance levels, the FM repeater is left active for general use.

At the request of AMSAT-EA, AMSAT has designated HADES-D as Spain-OSCAR 121 (SO-121). AMSAT congratulates AMSAT-EA, thanks them for their contribution to the amateur satellite community, and wishes them continued success on this and future projects.

The repeater works with FM/FSK (MSK144 has been tested too) with an uplink frequency of 145,875 MHz and a downlink frequency of 436,663.5 MHz (a bit lower than the 436.666 MHz expected). We have been able to verify that the modulation is more appropriate by narrowing the bandwidth, so it is recommended to use NFM in those devices allowing it.

AMSAT-EA is drafting a use and operation manual, which will be published shortly and which will indicate in detail some of the characteristics of the satellite and its working modes. Although it is not definitive, Amsat-EA is considering some special operating options such as reserving a day of the week exclusively for digital communications following the example we know with the AO-92.

Finally, please, remember that, as far as we know, HADES-D is the first satellite with FM repeater service mounted on a pocketqube platform. This standard is the smallest in terms of normalized satellite sizes. HADES-D size is 8x5x5 cm. Its panel surface and battery size are much smaller than the rest of the satellite repeaters in use, so HADES-D is not comparable to most of them either in radiated power or signal strength. HADES-D should be considered a QRP satellite.

ClarkSat-1 Deployed from ISS

ClarkSat-1 was one of two cubesats deployed from the International Space Station (ISS) via the Japanese “Kibo” module on Monday, December 18. Also known by the name “AMBITOUS,” and by the callsign JS1YLT, the satellite was described as follows in frequency coordination applications:

ClarkSat-1 is a 1U size satellite, and about 22 students of Clark Memorial International High School having amateur radio qualification or intending to obtain it will be engaged in the development of the satellite, and operate it by using the amateur radio band.

+ Optical Camera Mission To take pictures of the Earth and downlink them in 430 MHz band (GMSK, 4,800 bps). The pictures are to be received at control station and general amateur stations are also expected to receive them and report to us as the downlink schedule will be published on our website and social media.

+ Digi-talker Mission 40 to 120 seconds long Digi-talker signal (Voice or SSTV pictures in Robot 36 format recorded before launch) including the call sign and school name will be transmitted from the satellite and be expected that the general amateur stations will receive the signal and report back to us.

High school students with amateur radio license will be engaged in the development of the satellite, and high school students will operate the satellite. These activities will improve the amateur radio and satellite communication skills of the students. The project will also serve as a model case for the development of amateur satellites by the younger generation, and stimulate the interest of the younger generation in amateur radio and satellite communications. The satellite information, such as orbital position and operation time, will be actively disseminated to the world through the website and social media, so that radio amateurs all over the world will have an opportunity to receive image data and digi-talker signals transmitted from the satellite.

A downlink on 435.130 MHz has been coordinated by the International Amateur Radio Union (IARU) for ClarkSat-1. The ClarkSat-1 team requests signal reports sent to “[email protected]”. Satellite status reports will be posted on X.com @sat1_AMBITIOUS

WRC-23 Concludes with Wins for Amateur Radio

After four hectic weeks of the 2023 World Radiocommunication Conference (WRC-23), and a preceding week of Radiocommunication Assembly meetings, WRC-23 concluded on Friday, December 15. Amateur radio fared very well overall, despite the enormous pressures across the radio spectrum from LF to terahertz. This is a tribute to the effort of the International Amateur Radio Union (IARU) team, who at times had to work from 8:00 a.m. to as late as 2:00 a.m. the next morning, as well as on the weekends.

At the top of the amateur radio priority list was Agenda Item (AI) 9.1b, regarding the coexistence of the secondary amateur and amateur-satellite allocation with the primary radionavigation satellite service in the 1240 – 1300 MHz band. This had seen 4 years of strenuous effort prior to WRC and resulted in a recommendation being agreed upon at the Radiocommunication Assembly, followed by WRC-23 participants agreeing to mention the recommendation in a new footnote for the allocation. Both the recommendation and the footnote are an excellent outcome for the amateur services.

Other items were relevant to the amateur service and were prioritized beforehand:

AI 1.12: 40 – 50 MHz radar sounders. These are now largely limited to the polar area.

AI 1.14: 231.5 – 252 GHz re-allocations for Earth sensing. Fortunately, our secondary 241 – 248 GHz allocation is unchanged, and the primary allocation of 248 – 250 GHz is unaffected.

AI 9.1a: Space weather sensors was an item of major interest. A clear definition for such sensors was confirmed, with frequency protection being agreed upon as an agenda item for WRC-27.

AI 1.2: More broadband in the 3.3 GHz and 10 GHz bands (in Region 2). This is a difficult challenge, as the amateur services are secondary with numerous (mainly South American) countries allocating mobile broadband by way of footnotes. Instead of a region-wide designation for IMT at 10.0 – 10.5 GHz in Region 2, there is a footnote limited to a dozen countries.

WRC-23 agreed to an agenda for the next conference under AI 10. This AI had an unprecedented number of proposals for WRC-27 and preliminary ones for WRC-31. Following the relatively quick agreement on AI 9.1b, the IARU team switched most of its efforts to the following future proposals to reduce the impact on the amateur services, as numerous amateur bands were under consideration.

WRC-27

The WRC-27 agenda will have 19 items. The following are the most relevant to the amateur services:

1300 – 1350 MHz: A previous proposal for this band, adjacent to 23 centimeters, was suppressed, providing certainty for our secondary allocation.

Space Weather: This potential AI was initially very concerning, as the 0.1 – 20 MHz and 28 and 50 MHz bands were initially under consideration, until concerns were raised, and a team effort resulted in these allocations being removed from the topic.

Lunar Communications: This future agenda item initially included 70 centimeters and other bands where Earth-moon-Earth could be restricted. Fortunately, the UHF aspect of this AI was modified to exclude 430 – 440 MHz.

10 GHz: We were fortunate that this band was withdrawn from another round of consideration for mobile broadband, especially in Region 1.

WRC-31

A record number of preliminary item resolutions were agreed on. The following two are especially relevant:

Wireless Power Transmission (WPT): Both near-field and beamed are being considered as part of the International Telecommunication Union radio regulations, whilst minimizing the impact from interference.

275 – 325 GHz Allocations: This will include an opportunity for the amateur and amateur-satellite service.

The IARU team worked effectively to minimize the amateur bands from future studies, which is a great result for amateur radio.

IARU is very pleased with the overall result of WRC-23. The IARU team has already started to discuss and consider how to engage and resource for the next cycle leading up to WRC-27. IARU WRC Coordinator and Vice President Ole Garpestad, LA2RR, expressed his pleasure with the results and complimented the extraordinary effort of the dedicated team of IARU volunteers who worked long hours to achieve the results that will benefit all amateurs.

The IARU team includes ARRL Technical Relations Specialist Jon Siverling, WB3ERA. WRC-23 ran from November 20 – December 15, 2023.

Changes to AMSAT-NA TLE Distribution for Dec. 22

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/.

HADES-D/SO-121 has been positively identified with NORAD Cat 58567

The following satellite has been added to this week’s AMSAT-NA TLE distribution:

ARISS NEWS

Amateurs and others around the world may listen in on contacts between amateurs operating in schools and allowing students to interact with astronauts and cosmonauts aboard the International Space Station. The downlink frequency on which to listen is 145.800 MHz worldwide.

No contacts have been scheduled from 2023-12-21 to 2024-01-14. The complete schedule page has been updated as of 2023-12-21 05:00 UTC.

SSTV from the ISS was to be sent on 145.800 MHz using the PD120 format. The event was scheduled for Sat 2023-12-16 at 10:15 UTC through Tue 2023-12-19 around 18:00 UTC. Unfortunately there is an issue that is still attempting to be resolved, so no signals were received. Hopefully the event can be rescheduled in the near future. The Service Module radio is temporarily stowed.

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

The crossband repeater continues to be active (145.990 MHz up {PL 67} & 437.800 MHz down), but operation has been interrupted due to undocking maneuvers this past week. 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.

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

Satellite Shorts From All Over

+ NASA has released a three minute video retrospective of its accomplishments in 2023. The video may be viewed at https://www.youtube.com/watch?v=YQWespzOtzI (ANS thanks NASA for the above information)

+ NASA’s Deep Space Optical Communications experiment beamed an ultra-high definition streaming video on Dec. 11 from a record-setting 19 million miles away (31 million kilometers, or about 80 times the Earth-Moon distance). The demo transmitted the 15-second test video via a cutting-edge instrument called a flight laser transceiver. Uploaded before launch, the short ultra-high definition video features an orange tabby cat named Taters chasing a laser pointer. Taters is the pet of an employee of NASA’s Jet Propulsion Laboratory, and the cat is reported to be totally unimpressed by the accomplishment. (ANS thanks NASA for the above information)

+ December 6 marked the 25th anniversary of the International Space Station. On Dec. 6, 1998 the first two elements of the station, Unity and Zarya, were mated by the crew of space shuttle Endeavour’s STS-88 mission. Since then, 273 people from 21 countries have visited the station. (ANS thanks The Orbital Index and NASA for the above information)

+ NASA’s Mars Rover, Perseverance, recently marked 1,000 “sols” (Martian days) on the red planet, after landing at Jezero Crater on February 18, 2021. It’s companion Mars helicopter, Ingenuity, the first robot ever to explore the skies of a world beyond Earth, made its 70th flight on Friday, Dec 22. (ANS thanks The Orbital Index and NASA for the above information)

+ Voyager 1 has stopped returning useful data to Earth due to a problem with the spacecraft’s Flight Data System (FDS) computers. It could take several weeks for engineers to develop a new plan to remedy the issue. Launched in 1977, the spacecraft and its twin, Voyager 2, are the two longest-operating spacecraft in history [behind AO-7, that is]. In addition, commands from mission controllers on Earth take 22.5 hours to reach Voyager 1, which is exploring the outer regions of our solar system more than 15 billion miles (24 billion kilometers) from Earth. That means the engineering team has to wait 45 hours to get a response from Voyager 1 and determine whether a command had the intended outcome. (ANS thanks NASA for the above information)

+ A French small rocket project, aptly-named “Baguette-One”, received more funding from the French government to continue developing a low-cost hybrid rocket engine. Baguette One should take flight in the beginning of 2026 and aims to put small satellites up to 250 kilograms into orbit. (ANS thanks The Orbital Index and LeMonde for the above information)

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. You can apply for the ARISS SSTV Award by uploading your decoded image and completing the Application Form using the information provided at https://ariss.pzk.org.pl/sstv. Don’t forget that you can receive a QSL Card from the International Space Station by receiving and decoding a SSTV image. More information about how to obtain a QSL Card can be found at https://www.ariss.org/qsl-cards.html.

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 Top 100 Rovers December 2023 Rankings

The December 2023 rankings for the Top 100 Rovers (Mixed LEO/MEO/GEO) in satellite operations, as determined by @GridMasterMap on Twitter, has been released. The ranking is determined by the number of grids and DXCC entities activated, taking into account only those grids where a minimum number of QSOs logged on the gridmaster.fr website have been validated by a third party. Grid numbers do not directly reflect the exact number of activations. Satellite operators are encouraged to upload their LoTW satellite contacts to https://gridmaster.fr in order to provide more accurate data.

+ Upcoming Contacts

No upcoming school contacts are scheduled.

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.

The packet system is listed as temporarily stowed. Look for SSTV transmissions on 145.800 MHz between December 16th through December 19th.

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.

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.

the 2023 coins will no longer be available.

To commemorate the 40th anniversary of its launch
on June 16, 1983, this year’s coin features
an image of AMSAT-OSCAR 10.

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.

[ANS thanks NASA for the above information.]

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.

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.

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.

Happy 10th Birthday FUNcube-1 (AO-73)

November 21, 2023, marks the tenth birthday of our very first CubeSat mission, FUNcube-1 (AO-73).

A very short time after the launch from Yasny in Russia and within a few minutes from deployment, the very first frame of data from the low power transmitter on board, was detected and decoded by ZS1LS in South Africa. He was able to relay the data over the internet from his Dashboard to the Data Warehouse and the numbers, appeared, as if by magic, at the launch party being held at the RSGB National Radio Centre at Bletchley Park.

After a very brief check out, the FUNcube team were able to switch the transmitter to full power, again at the very first attempt, and were quite amazed at the strength of the signal from the 300mW transmitter on 145.935 MHz. The transponder was then switched on and successfully tested, the first contact was between G6LVB and M5AKA who were both operating from the Bletchley Park car park.

The team finished the day with a request to AMSAT-NA for an Oscar number and were delighted to receive the AO73 Oscar 73 designation!

Since then, FUNcube-1, with a launch mass of less than 1kg, has operated continuously with only a very few interruptions. In excess of 53,500 orbits, 1.3 billion miles travelled, 61 million telemetry data packets transmitted, and with more than 10.9 million unique data packets downloaded and stored in the Data Warehouse.

The FUNcube team still receive many requests for Fitter message uploads for school events…please contact us by email to [email protected] giving us at least two weeks notice.

The FUNcube team continue to be very grateful to all the many stations around the world that continue to upload the telemetry that they receive to our Data Warehouse. They really need this data to provide a continuous resource for educational outreach.

AMSAT Servers Back In Service After Brief Outage

At approximately 21:04 UTC Tuesday November 21, our vendor Linode detected a failing disk on the hardware that runs our web, telemetry, source code control and Echolink servers and began to effect emergency data protection operations. AMSAT’s Engineering department is clearly working hard, because within 10 minutes they alerted the AMSAT IT department that they were having trouble accessing the server that holds the source code for our satellite projects.

Meanwhile Linode proceeded to “evacuate” our servers from the failing hardware, and migrated them to new hardware.

All services were restored by approximately 21:20 UTC and the servers appear to be happily settling in to their new home.

There is no sign of any data loss, but as always if you see anything out of the ordinary please write [email protected]

HERON Mk. II Reaches Orbit

The University of Toronto Aerospace Team (UTAT) Space Systems’ HERON Mk. II satellite lifted off from Vandenberg Space Force Base in California, aboard a Falcon 9 rocket of the SpaceX Transporter-9 mission.

As a rideshare mission to space, the Transporter-9 delivered HERON Mk. II — alongside 89 other small satellites — to an orbit approximately 540 kilometres above Earth’s surface. Marking the culmination of nearly a decade of work by student Space Systems engineers, the HERON Mk. II’s path to the launch pad was one of dedication and perseverance.

The UTAT are a team composed primarily of engineering students that designs and builds small satellites known as CubeSats. Team’s first satellite, HERON Mk. I — short for Human Experiment Relay On Nanosatellite — was a CubeSat developed from 2014–2016. For various reasons, the project did not end in a launch opportunity, and so HERON Mk. I was retired.

Since our team was performing work that required members to be on campus, the COVID-19 pandemic disrupted our original spacecraft assembly plans.

Any organization wishing to send a satellite into space and communicate with it via radio waves first needs to obtain the appropriate radio frequency (RF) licenses from Innovation Science and Economic Development Canada. Unfortunately, the process of obtaining these licenses for the HERON Mk. II satellite took significantly longer than expected and delayed the launch. Because of the delay, the team was forced to abandon the original biological mission.

Therefore, the team decided to shift the primary focus of the HERON Mk. II mission toward validating UTAT Space Systems’ RF communications capabilities and providing amateur radio and satellite operations experience to our members.

While waiting for the frequency licenses to be issued, a group of our teammates began designing an amateur ultra-high frequency (UHF) ground station. This is the apparatus that allows us to communicate with HERON Mk. II from the ground, via radio waves at a frequency of 437.12 megahertz. Now fully operational, the ground station currently resides on the sixth-floor roof of the Bahen Centre for Information Technology.

In September, a few team members travelled to Spaceflight’s facilities in Bellevue, Washington, where they placed HERON Mk. II inside its deployer that would later be mounted inside the Falcon 9 rocket for the SpaceX Transporter-9 mission.

Once the Falcon 9 rocket reached its intended orbit in space, HERON Mk. II was ejected from the rocket at 3:04 pm EST, and soon deployed its UHF antenna. The UHF antenna plays a crucial role in preventing any electromagnetic interference with the other satellites, which might otherwise distort the signals sent between HERON Mk. II and the ground station.

During the initial commissioning period, we will be actively trying to establish the first communications via the ground station. Afterward, HERON Mk. II will begin a year of regular operations during which the team will regularly monitor the satellite’s health.

The lessons learned from mission operations and monitoring the satellite’s health will inform the development of future satellite missions undertaken by UTAT Space Systems.

With the launch of HERON Mk. II, UTAT Space Systems has lowered the barrier to entry for space programs even further by becoming the first organization in Canada to receive the entirety of its satellite development funding from a student levy. This marks yet another paradigm shift in the industry, demonstrating that students are capable of sourcing their own space mission funding, rather than solely relying on government grants or commercial sponsorships.

From an educational perspective, the HERON Mk. II mission will enable team members to learn more about satellite operations and amateur radio and to gain knowledge that will carry forward to UTAT Space Systems’ future missions.

Starship Flies Higher

Seven long months after Starship’s first integrated flight test in April, Ship 25 launched atop Booster 9 on a second test flight, again targeting a ballistic trajectory with a planned splashdown north of Hawai’i.

This time, all 33 Raptor 2 engines on Booster 9 completed a full first-stage burn, producing a 300-meter-long exhaust plume and roughly twice the thrust of any other object flown by humanity.

The 121-meter monster rocket also completed what appeared to be a successful hot stage separation, with B9 shutting down all but three of its Raptors (which were throttled to 50%) followed by S25’s six engines starting up to push the ship away from the booster.

Hot staging reduces gravity losses and keeps the upper stage continuously under thrust for fuel settling.

After stage separation, B9 completed a somewhat vigorous flip and, perhaps due to propellant slosh or damage, had trouble relighting its Raptor engines. (Engines that ingest tank pressurization gas instead of propellant generally end up functioning quite destructively.)

After several “high energy” events at the aft end of Booster 9, an explosion originating from its common bulkhead rapidly disassembled the booster.

After separation, Starship’s upper stage burned until seconds before entering its planned coast phase—climbing to an altitude of 148 km and over 6.7 km/s, reaching space and very nearly hitting orbital velocity.

However, S25 appeared to trigger its automated flight termination system during terminal guidance, possibly due to a leak in its oxygen tank—debris from the explosion were caught on NOAA radar extending past Puerto Rico.

The thermal protection system (TPS) made up of 18,000 tiles, appeared to lose a significant number of tiles during the launch, especially ones that were glued on near weld points, making the ship unlikely to have survived reentry even if the flight had made it that far.

S28’s TPS tiles are said to have an improved adhesion process that has been tested with a suction cup plus force meter to verify attachment. One additional clear success was the performance of SpaceX’s much improved “stage zero”—the water deluge system appeared undamaged and very little other damage and debris have been spotted by ever-vigilant tank watchers.

Due to a complete loss of both stages, the FAA will conduct another mishap investigation, although many hope it will be significantly more streamlined due to the improved FTS functionality and better performance of the launch system—in particular, the Fish and Wildlife Service may not be involved this time.

The always-optimistic Musk suggests a next test flight for Starship in 3-4 weeks, and with plenty of hardware waiting in the wings (S28 and B10 are likely up next), the timeline will probably be determined yet again by the mishap investigation and mitigation process. NASA seems keen to get on with it though as the agency believes its lunar lander mission may take up to 20 Starship launches

ITU RA-23 Adopts Resolution for Space Spectrum

The ITU Radiocommunication Assembly 2023 (RA-23), a precursor to the World Radiocommunication Conference, WRC-23, wrapped up on November 17 with a lot of new resolutions covering 6G standards, sustainable usage of space spectrum and gender equality.

RA-23, which was held last week in Dubai, adopted the new Recommendation ITU-R M. 2160 on the “IMT-2030 Framework,” which sets the basis for development of 6G, a.k.a. IMT-2030. The next phase will be the definition of relevant requirements and evaluation criteria for potential radio interface technologies.

The assembly also adopted a a new resolution on space sustainability to facilitate the long-term sustainable use of radio spectrum and associated satellite orbit resources used by space services, in in accordance with Resolution 219 (Bucharest, 2022). The ITU says this resolution will benefit the satellite sector and support further cooperation with other United Nations organizations.

RA-23 also finished a new ITU-R Recommendation on the protection of the radio navigation-satellite service and amateur satellite services, and adopted a a new resolution on the use of IMT technologies for fixed wireless broadband.

The assembly also agreed to revise ITU-R Resolution 65 to facilitate studies looking at the compatibility of current regulations with potential 6G IMT radio interface technologies for 2030 and beyond.

Resolution ITU-R 8-3 was also revised to promote the participation of engineers and scientists from developing countries in radiowave propagation campaigns in tropical and subtropical regions with limited data monitoring.

The RA-23 resolutions arrive just ahead of WRC-23, which commenced November 20 in Dubai and will run until 15 December 2023. Hot items on the agenda include the ongoing battle between the satellite and mobile sectors for 5G spectrum, especially as non-terrestrial networks become part of 3GPP’s 5G standards, the development of direct-to-device satellite services, and revisiting rules about satellite power limits for LEO satellites, to name a few.

Satellite Shorts From All Over

+ EIRSAT-1 is expected to launch on a Space X Falcon 9 rocket from the Vandenberg Air Force Base in California, USA, on November 29, 2023. It will have a downlink on the IARU coordinated frequency of 437.100 MHz, see https://iaru.amsat-uk.org/finished_detail.php?serialnum=639. Information on the beacon can be found at https://github.com/ucd-eirsat-1/beacon. EIRSAT-1 was built by students from University College Dublin under the framework of ESA Academy’s Fly Your Satellite! programme (FYS). (ANS thanks AMSAT-UK for the above information)

+ The European Space Agency conducted a long-duration firing of an Ariane 6 prototype Nov. 23, one of the final tests before the agency is ready to set a date for the rocket’s inaugural launch. ESA said Ariane 6 “passed” the test in a statement shortly afterwards, describing it as a “seven-minute full firing” of the engine, rather than the nearly eight minutes advertised beforehand. (ANS thanks SpaceNews.com for the above information)

+ The tool bag recently lost by NASA astronauts during a spacewalk is now orbiting Earth and is surprisingly visible to stargazers. The object can appear as bright as a 6th-magnitude star. The tool bag changes slightly in brightness, suggesting the object is tumbling as it orbits our planet. Although the tool bag was ahead of the International Space Station (ISS) by about a minute or two shortly after the incident, it is gradually appearing farther ahead of the ISS as it loses altitude. By mid-November, the tool bag should be ahead by about ten minutes. (ANS thanks EarthSky.org for the above information)

+ With the Sun in the way of our messages, Curiosity and Perseverance, along with Ingenuity, MRO, Odyssey, and MAVEN, are hunkered down during the Mars solar conjunction communication blackout. Curiosity has now spent 4,000 sols exploring the red planet and has driven 32 km. (ANS thanks The Orbital Index for the above information)
