The rocket carrying the PARUS T1A satellite failed to reach orbit. Space One, a Japanese space startup, said its second attempt to launch a rocket carrying satellites into orbit had been aborted minutes after liftoff Wednesday and destroyed itself, nine months after the company’s first launch attempt ended in an explosion. Space One’s Kairos No. 2 rocket lifted off from a coastal site in the mountainous prefecture of Wakayama in central Japan. The company said it had aborted the flight after concluding that it was unlikely to complete its mission. “We are very sorry that we could not achieve as far as a final stage of the mission,” Space One President Masakazu Toyoda told a news conference Wednesday. “We don’t consider this a failure because we are getting valuable data that will help our pursuit toward a next challenge.” He said he hoped to find the cause to address the problems as soon as possible to achieve a success next time. Company executive and space engineer Mamoru Endo said the abnormality in the first stage engine nozzle or its control system is likely to have caused an unstable flight of the rocket, which started spiraling in midflight and eventually destroyed itself about three minutes after liftoff, using its autonomous safety mechanism. The Kairos No. 2 rocket was carrying five small satellites, including one from the Taiwanese space agency and several from Japanese startups. The Taiwanese satellite was PARUS-T1A a 3U CubeSat that featured an FM crossband repeater, as well as an APRS digipeater to provide global amateur activities at the same frequency of ISS APRS channel 145.825MHz. A second Taiwanese amateur satellite, PARUS-T1, carrying an APRS store-and-forward system, is still scheduled for launch next month on a SpaceX mission. Both satellites were constructed by students at National Formosa University. Space One said it had fixed the cause of the debut flight failure, which stemmed from a miscalculation of the rocket’s first-stage propulsion. Japan hopes the company can pave the way for a domestic space industry that competes with the United States.

Their space mission was extended again. That means they won’t be back on Earth until spring, 10 months after rocketing into orbit on Boeing’s Starliner capsule. The two test pilots planned on being away just a week or so when they blasted off June 5 on Boeing’s first astronaut flight to the International Space Station. Their mission grew from eight days to eight months after NASA decided to send the company’s problem-plagued Starliner capsule back empty in September. Now the pair won’t return until the end of March or even April because of a delay in launching their replacements, according to NASA. *NASA shared a holiday snapshot of astronauts Don Pettit and Suni Williams on Dec. 17. [Credit: NASA Johnson]* NASA’s next crew of four was supposed to launch in February, followed by Wilmore’s and Williams’ return home by the end of that month alongside two other astronauts. But SpaceX needs more time to prepare the brand new capsule for liftoff. That launch is now scheduled for no earlier than late March. Last month, news articles suggesting that Ms. Williams was experiencing health problems during her unplanned extended stay in orbit set off widespread rumors on social media. NASA’s medical chief, Dr. James Polk, assured the public on November 14 that Williams is healthy and not suffering from any medical problems. “I think there’s some rumors around outside there that I’m losing weight and stuff,” Williams said in an interview on November 12. “No, I’m actually right at the same amount. Things shift around quite a bit, you know? ” Not only is she healthy, according to her and NASA, but they made Williams commander of Expedition 72 crew. As KD5PLB, she continues to be an active participant in ARISS contacts during her time aboard the ISS.

Imagine how much more difficult it would be to diagnose a helicopter accident that took place 69 million miles away with none of the usual data present to help. NASA had to do just that after its Ingenuity Mars Helicopter suffered an accident on Jan. 18, 2024, that has since left it grounded in a crater on Mars. And now, after months of collecting data, the space agency may have finally figured out what happened. On April 19, 2021, the NASA Ingenuity Mars Helicopter made history by lifting off the Jezero Crater’s floor and becoming the first aircraft to fly on a celestial entity other than Earth. The helicopter was supposed to fly only five experimental flights over 30 days to demonstrate that flight on Mars was possible. But it exceeded all expectations, conducting 72 flights over three years, setting all sorts of altitude records in the process, ending with that early 2024 accident. *The wreckage of the Inguity Mars Helicopter as seen by the Mars Rover Perseverance. The helicopter is on the right and the broken rotor is approximately 49 feet away on the left. [Photo: NASA/JPL-Caltech/LANL/CNES/CNRS]* The final moments of the helicopter’s flight were more or less a mystery at first. Ingenuity lifted off like it had 71 times before. Then camera footage showed that it began initiating descent after just 19 seconds of flight. By the time 32 seconds had elapsed, the helicopter was on the Martian surface again and had halted communications. Six days later, the helicopter beamed back images that showed it had sustained severe rotor-blade damage and would no longer be able to fly. Now, NASA believes that the navigation system was ultimately to blame. The navigation system used the helicopter’s downward-facing camera to track visual features on the ground. During this final flight, the helicopter was flying over a portion of the Jezero Crater that is known for textured, featureless sand ripples. The navigation system was thus unable to find any suitable ground features to track for a landing. From there, several things went wrong. NASA says that the helicopter made hard contact with a sand-ripple slope, causing it to pitch and roll. The sudden change in altitude was too much for the rotor blades, and four of them broke off at their weakest points. This caused the rotor system to vibrate excessively, which ripped one of the blades clean off. Finally, the incident generated an excessive power draw that caused communications to fail. *NASA’s graphic depicts the most likely scenario for the accident, in which Ingenuity landed hard on a sand-ripple slope, causing irreparable rotor-blade damage.[NASA/JPL-Caltech]* “When running an accident investigation from 100 million miles away, you don’t have any black boxes or eye witnesses,” said Håvard Grip, Ingenuity’s first pilot and research technologist at JPL Robotics. “While multiple scenarios are viable with the available data, we have one we believe is most likely: Lack of surface texture gave the navigation system too little information to work with.” Nobody expected Ingenuity to last as long as it did. Its flights gave researchers excellent aerial views of our red neighbor. Even now, as it lies in the sands of the Jezero Crater, Ingenuity can no longer fly but still beams back weather and avionics data to NASA. The avionics data along with the flight data from Ingenuity’s 72 flights — combined with Ingenuity’s incredible longevity — are helping NASA develop smaller, lighter avionics for future aircraft on Mars. “Because Ingenuity was designed to be affordable while demanding huge amounts of computer power, we became the first mission to fly commercial off-the-shelf cellphone processors in deep space,” said Ingenuity project manager Teddy Tzanetos. “We’re now approaching four years of continuous operations, suggesting that not everything needs to be bigger, heavier and radiation-hardened to work in the harsh Martian environment.” Tzanetos and his team are already working on another Mars helicopter. It’s approximately 20 times heavier than the Ingenuity and is being designed to carry several pounds of science equipment while autonomously exploring remote locations on Mars.

(ANS thanks AMSAT-UK for the above information.) + Two Chinese astronauts aboard their country’s orbiting space station spent nine hours working outside in the cold vacuum of space, the longest recorded spacewalk, the Chinese space administration has said. The astronauts on China’s Shenzhou-19 mission, Cai Xuzhe and Song Lingdong, finished their first “extravehicular activities” — spacewalking in popular parlance — this week, apparently nudging past the previous record of eight hours and 56 minutes set by two American astronauts in 2001, according to China’s Manned Space Agency. The feat was another sign of China’s ambitions to project its power and prestige in space. (ANS thanks The New York Times for the above information.) + The internet news site MSN recently published a feature on the history of amateur radio and astronauts in orbit, beginning with Owen Garriott, W5LFL, in 1983 and continuing to the present ARISS program. “How Amateur Radio Is Connecting Astronauts In Space With Kids On Earth” was written by Leonard David. See it at http://bit.ly/4gnfE3y (ANS thanks msn.com for the above information.) + The first Block 2 version of the giant SpaceX Starship, Ship 33, recently rolled out for testing and completed its first static fire test. It will be stacked on Booster 14 before it is targeted to complete the first flight of the Block 2 reusable upper stage in January. This upgraded Ship adds catch hardware and an additional ring, making it 1.8 m taller and now totaling 124.4 m (408 feet) when eventually stacked on top of Booster 14. The added height will allow it to pack 300 tons more propellant.

Here is a great opportunity to listen to the ISS. The transmission should be high power and easy to hear and decode with a rubber duckie. Since there are no leaves and trees to interfere it can be fun. 73 de VE2LJV Samuel Galet Sent from my Galaxy -------- Original message -------- From: Mark Thompson via AMSAT-BB <amsat-bb(a)amsat.org> Date: 2024-12-20 4:46 a.m. (GMT-05:00) To: digitalatv(a)groups.io Cc: AMSAT BB <amsat-bb(a)amsat.org> Subject: [AMSAT-BB] ISS SSTV Experiment, 14:55 UTC - December 25th to 14:20 UTC - January 5th ISS SSTV Experiment, 14:55 UTC - December 25th to 14:20 UTC - January 5th [image.png] _._,_._,_ ________________________________

Upcoming ARISS Contact Schedule as of 2024-12-20 05:00 UTC

Upcoming ARISS Contact Schedule as of 2024-12-20 05:00 UTC Quick list of scheduled contacts and events: TBD (***) ARISS school contacts are currently planned to resume the week of 2025-01-13 to 2025-01-19. (***) Many times a school may make a last minute decision to do a Livestream or run into a last minute glitch requiring a change of the URL but we at ARISS may not get the URL in time for publication. You can always check https://live.ariss.org/ to see if a school is Livestreaming. The crossband repeater continues to be active. 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. All dates and times listed follow International Standard ISO 8601 date and time format YYYY-MM-DD HH:MM:SS The complete schedule page has been updated as of 2024-12-20 05:00 UTC. (***) Here you will find a listing of all scheduled school contacts, and questions, other ISS related websites, IRLP and Echolink websites, and instructions for any contact that may be streamed live. https://www.amsat.org/amsat/ariss/news/arissnews.rtf https://www.amsat.org/amsat/ariss/news/arissnews.txt The successful school list has been updated as of 2024-12-17 20:30 UTC. https://www.amsat.org/amsat/ariss/news/Successful_ARISS_schools.rtf ####################################################################################################################################### 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 07:30 – 19:30 UTC. The most common times to find a crew member making casual periods are about one hour after waking up and about an hour 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 sometimes active. Check the status at https://www.ariss.org/ or http://www.issfanclub.eu to see if the packet system is active or not. As always, if there is an EVA, a docking, or an undocking; the ARISS radios are turned off as part of the safety protocol.

(***) Watch for Livestream at https://www.youtube.com/live/DBafZYpxolI Sally Ride Elementary School, Orlando, Florida, direct via K1AA The ISS callsign is presently scheduled to be NA1SS The downlink frequency is presently scheduled to be 145.800 MHz The latest information on the operation mode can be found at https://www.ariss.org/current-status-of-iss-stations.html The scheduled crewmember is Sunita Williams KD5PLB The ARISS mentor is AA4KN Contact is go for: Tue 2024-12-17 18:49:38 UTC 30 deg Many times a school may make a last minute decision to do a Livestream or run into a last minute glitch requiring a change of the URL but we at ARISS may not get the URL in time for publication. You can always check https://live.ariss.org/ to see if a school is Livestreaming. The crossband repeater continues to be active. 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. All dates and times listed follow International Standard ISO 8601 date and time format YYYY-MM-DD HH:MM:SS The complete schedule page has been updated as of 2024-12-16 22:00 UTC.

(***) https://www.amsat.org/amsat/ariss/news/Successful_ARISS_schools.rtf ####################################################################################################################################### 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 07:30 – 19:30 UTC. The most common times to find a crew member making casual periods are about one hour after waking up and about an hour 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 sometimes active. Check the status at https://www.ariss.org/ or http://www.issfanclub.eu to see if the packet system is active or not.

ARISS News Release No. 24-92
by David H Jordan 16 Dec '24

16 Dec '24

*ARISS News Release No. 24-92* *Dave Jordan, AA4KN * *ARISS PR* *dave.jordan(a)ariss-usa.org <dave.jordan(a)ariss-usa.org>* *FOR IMMEDIATE RELEASE* *ARISS Contact is Scheduled with Students at * *Sally Ride Elementary School, Orlando, Florida, USA* December 15, 2024—Amateur Radio on the International Space Station (ARISS) has received schedule confirmation for an ARISS radio contact between an astronaut aboard the International Space Station (ISS) and students at the Sally Ride Elementary School located in Orlando, FL. ARISS conducts 60-100 of these special amateur radio contacts each year between students around the globe and crew members with ham radio licenses aboard the ISS. Sally Ride Elementary, located in a large suburban area of Orlando, FL, is an aviation and aerospace magnet school serving about 400 children, from prekindergarten to fifth grade. Named after Dr. Sally Ride, the first American woman to fly in space, the school campus was formed out of two merged public schools. In addition to their Aviation and Aerospace Magnet Program, students in the school’s STEM classes have designed rockets and solar cars, built airplanes and hot air balloons, and solved engineering problems. Students are also participating in the TomatoSphere NASA project in which they compare the growth of two groups of tomato seeds: one that had spent 36 days on the ISS and one that did not. The school organized their first ‘Astro Night’ allowing students to observe celestial bodies in our solar system (our Moon and Saturn) using higher power telescopes provided by the Central Florida Astronomical Society. In preparation for this ARISS contact, students have been learning about radio communication, and how to build an antenna from members of the Orlando Amateur Radio Club. Students were also able to directly observe the ISS passing over their area. This will be a direct contact via Amateur Radio allowing students to ask their questions of astronaut Sunita Williams, amateur radio call sign KD5PLB. The downlink frequency for this contact is 145.800 MHz and may be heard by listeners that are within the ISS-footprint that also encompasses the relay ground station. The amateur radio ground station for this contact is in Orlando, FL. Amateur radio operators using call sign K1AA, will operate the ground station to establish and maintain the ISS connection. The ARISS radio contact is scheduled for December 17, 2024 at 1:49:38 pm EST (Orlando, FL) (18:49:38 UTC, 12:49 pm CST, 11:49 am MST, 10:49 am PST). Live streaming of the event is expected to be made available to the general public. Check our social media listed below for any updates. *_______________________________* As time allows, students will ask these questions: 1. Why did you decide to become an astronaut? 2. I get a sticker when I visit the doctor. Do you have doctors in space? 3. How often do you talk to your family? 4. I want to be an astronaut; what advice do you think I need to make my dreams come true? 5. Do you have a favorite food you eat in space? 6. Have you ever been on a spacewalk? 7. How long have you been in space and how many days before you return? 8. What do you do for fun in the ISS? 9. How do you train your body to go to space? 10. When in space, what do you miss the most from Earth? 11. Do your clothes get dirty in space like mine when I play outside? 12. What do you do in space? What is your role? 13. Are you excited to talk to us today? 14. What is the oldest experiment that is still in the space station? 15. Who is driving the ISS if everyone is sleeping? 16. How do you celebrate holidays or birthdays in ISS? 17. Do you have a favorite teacher who was an influence on you? 18. When you were my age, what was your favorite and least favorite subject? 19. Do your ears pop and hurt when you launch into space and return to Earth? 20. Can you see other planets, comets, and stars from the ISS orbit? 21. What kind of animals have gone to space? 22. Do you grow plants in ISS? 23. When you come back to earth do you have minor side effects? 24. What do you like the most about being an astronaut? *About ARISS:* Amateur Radio on the International Space Station (ARISS) is a cooperative venture of international amateur radio societies and the space agencies that support the ISS.

AO73 / FUNcube1 Mode change
by graham＠shirville.com 15 Dec '24

15 Dec '24

Hi Everyone, A quick note to advise that AO73 /FUNcube 1 has been switched from autonomous mode to continuous transponder mode for the holiday period. This means that the transponder is available for use 24/7. The regular telemetry is still being transmitted but at a low power setting of around 40mW! It is anticipated that we will revert to autonomous mode with full power telemetry when in daylight sometime after January 5th 2025. In the meantime - have even more un on the transponder. Best wishes from the FUNcube team!

The deployment was part of JAXA’s J-SSOD#30 mission and included DENDEN-01, LignoSat, ONGLAISAT, YODAKA and YOMOGI satellites. Two of these satellites, LignoSat and YOMOGI, have received previous IARU coordination to operate over amateur radio frequencies. LignoSat was developed by Kyoto University and Sumitomo Forestry Co., Ltd. This CubeSat tests the use of wooden materials in space by measuring strain, temperature, and geomagnetism, along with detecting single event upsets (SEU). Amatuer radio satellite enthusiasts were ready to decode telemetry from the satellite this week, but unfortunately there has been no reported reception of either CW or AX.25 packets on the satellite's coordinated frequency of 435.820 MHz. [https://www.amsat.org/wordpress/wp-content/uploads/2024/12/LignoSat-1U-Wood…]<https://www.amsat.org/wordpress/wp-content/uploads/2024/12/LignoSat-1U-Wood…> LignoSat, a 1U solar-powered satellite with wood panels, will orbit earth for six months. [Credit: Kyoto University<https://www.kyoto-u.ac.jp/en>] DENDEN-01 was developed by Kansai University and partner institutions. Its mission includes testing advanced nanosatellite technologies, such as temperature-stabilizing devices, thin solar modules, and compact S-band communication systems. The satellite also supports educational activities and data analysis using a compact hyperspectral camera. ONGLAISAT is a 6U CubeSat co-developed by the Taiwan Space Agency, the University of Tokyo, and ArkEdge Space Inc. It features a telescope for high-resolution Earth imaging using Time Delay Integration (TDI) technology. This mission aims to produce clear and high signal-to-noise ratio images for Earth observation. YOMOGI was developed by the Chiba Institute of Technology. Its mission combines environmental monitoring and engineering education. The satellite observes red tide in Tokyo Bay, monitors water pollution in Uganda, and uses APRS to send sensor data to ground stations. Many 4800 baud GMSK telemetry packets have been received and decoded over the last few days indicating that the satellite is functioning well. More information can be found on SatNOGS regarding recent observations: https://db.satnogs.org/satellite/HHVN-9456-4962-8588-2802#data [https://www.amsat.org/wordpress/wp-content/uploads/2024/12/YOMOGI-1U-APRS-S…]<https://www.amsat.org/wordpress/wp-content/uploads/2024/12/YOMOGI-1U-APRS-S…> YOMOGI will capture images of the Earth surface using both Bandpass and RGB cameras. [Credit: Chiba Institute of Technology<https://www.it-chiba.ac.jp/english/>] YODAKA was developed by ArkEdge Space Inc. and other collaborators. It features a store-and-forward communication mission, collecting and retransmitting text messages from users on Earth, as well as a camera mission to capture Earth imagery. These activities support educational programs at Iwate Prefectural Hanamaki Kita High School and rural revitalization efforts in Hanamaki City. The deployment highlights collaboration between JAXA, Space BD Inc., Mitsui Bussan Aerospace Co., Ltd., and the J-CUBE program, which fosters academic and commercial utilization of CubeSats. Amateur radio operators and educational institutions are actively participating in tracking and analyzing data from these satellites.

Called the Proba-3 mission, the two spacecraft will conduct formation flying and create artificial solar eclipses to capture images of the Sun's outer atmosphere, which is usually hidden by its brightness. The satellites launched aboard India's Polar Satellite Launch Vehicle (PSLV) at 5:34 am EST (10:34 UTC) and were placed into an elliptical orbit with a low point of 356 miles (573 kilometers) and a high point of 37,632 miles (60,563 kilometers). Early next year, the Coronagraph satellite, carrying instruments to image the Sun, and the Occulter satellite, equipped with navigation sensors and thrusters, will separate to begin their experiments. The Occulter will position a disk to block the Sun’s surface, casting a shadow on the Coronagraph satellite. [https://www.amsat.org/wordpress/wp-content/uploads/2024/12/Proba-3-Coronagr…]<https://www.amsat.org/wordpress/wp-content/uploads/2024/12/Proba-3-Coronagr…> Proba-3 completed its final operations tests at Redwire’s Belgium facilities in October [Credit: Redwire Space<https://x.com/RedwireSpace>] This arrangement allows scientists to create artificial eclipses, blocking sunlight to reveal the solar corona. Natural solar eclipses offer only brief observation windows, and traditional coronagraphs on single spacecraft face challenges like diffraction. Proba-3 addresses these limitations by keeping the two satellites 150 meters apart, enabling clearer imaging of the Sun's outer atmosphere. Proba-3 uses advanced navigation technology, including inter-satellite radio links, cameras, and a laser-ranging system. This system maintains millimeter-scale precision between the satellites, allowing them to create artificial eclipses lasting up to six hours. The mission aims to conduct at least 1,000 hours of such observations during its two-year operational phase.

[Credit: ESA<https://www.esa.int/> / P. Carril] The mission’s scientific goal is to observe a part of the corona that existing instruments cannot study. This region is critical for understanding solar phenomena such as coronal mass ejections and the acceleration of the solar wind, which affect space weather and Earth. The mission will also capture high-frequency images to study plasma waves and jets that may heat the corona and drive the solar wind. Proba-3 also serves as a test of formation-flying technology. ESA officials hope the techniques demonstrated will be used in future missions, such as Mars Sample Return or space debris removal. "Proba-3 is an important step toward more complex space operations," said Josef Aschbacher, ESA's director general. "This mission shows how smaller spacecraft can work together to achieve goals that were not possible before."

NASA Administrator Bill Nelson emphasized that this timeline keeps the U.S. ahead of China's goal to land on the moon by 2030, highlighting the competitive nature of the space race. The delays follow concerns about the Orion capsule’s heat shield, which cracked during reentry after the uncrewed Artemis I test mission in 2022; Artemis II will proceed with adjustments to the capsule’s trajectory, while future missions will feature an upgraded heat shield. Artemis, initiated under former President Trump’s administration, aims not only to return astronauts to the moon but also to establish lunar bases as a stepping stone for Mars exploration, despite rising costs and development delays. The program's reliance on SpaceX’s Starship for lunar landings has raised questions about its cost-effectiveness, especially under the incoming Trump administration. Nelson expressed optimism about Artemis's continuity under NASA’s next administrator, Jared Isaacman, amid ongoing bipartisan and international support for lunar exploration.

This marks a milestone for SpaceX, as it will be the company's first time launching a nuclear-powered payload, a domain previously dominated by United Launch Alliance (ULA). The RTG will generate electricity from plutonium-238, chosen because Titan's dim and cloudy atmosphere precludes the use of solar power. Dragonfly will explore Titan's surface by hopping between locations using its eight rotors, investigating organic molecules essential to understanding the building blocks of life. Originally set for a 2026 launch, delays due to redesigns, COVID-19 impacts, and supply chain issues have pushed the timeline to July 2028, with costs escalating to $3.35 billion. This mission, one of NASA's most ambitious robotic endeavors, underscores the transition to new-generation rockets for launching nuclear payloads, with SpaceX's Falcon Heavy beating ULA's Vulcan rocket in competitive bidding for this historic mission.

Re: Satellite names and TLEs
by Nico Janssen 15 Dec '24

15 Dec '24

David, Let me elaborate a bit on Joe's great comments. The source of the TLEs in the Satellite Catalog (SatCat) is the 18thSDS. They publish only the TLEs of non-classified objects through Space-Track.org, which is the interface between the 18thSDS and 'the outside world'. The TLEs for classified objects are generated and published by amateur observers. For some reason many people continue to use the name NORAD when referring to the SatCat. But NORAD has NOT been involved in the SatCat since the early seventies of the previous century. Since that time several other military organizations have been responsible for the maintenance of the SatCat. Currently it is the 18thSDS. The unique identification numbers for the objects in the SatCat are called Catalog Numbers (CatNr), so not NORAD Numbers. Some other names are also used, e.g. Object Numbers or, more recently, Satellite Numbers (SatNo). But that last name suggests that the objects are always satellites, while of course they can be Rocket Bodies (R/B) or pieces of debris. So again, the name NORAD does NOT apply. Best to remove that word completely from your vocabulary ;-) . Another misunderstanding is that the 18thSDS identifies new satellites after their launch. That is not what happens. In the radar tracking network they can only see 'blips' on their radar screens. But they can not tell which blip belongs to which satellite. They can generate TLEs for all the observed objects without knowing which satellites are involved. So they depend on outsiders to identify the satellites for them. I try to help by carefully matching measured doppler curves with doppler curves that are calculated using the available TLEs. Usually my ID information is used in CelesTrak's SatCat. But the 18thSDS applies the strict rule that they may only accept ID information coming from the Owner/Operator of the involved satellite. Unfortunately many satellite owners don't know that they are responsible for identifying their satellite and then inform the 18thSDS accordingly. Also many foreign entities don't (want to) inform the 18thSDS of their satellite IDs. Therefore you see many unidentified objects in the SatCat, even though IDs are available through other sources. 'Satellite names' is another long discussion... 73, Nico PA0DLO On 13-12-2024 21:47, David Spoelstra via AMSAT-BB wrote: > > I’m trying to understand the process of naming satellites and putting > their TLEs in the official sources. > > > It seems like Space-Track is the official source of TLEs.

Re: Satellite names and TLEs
by Jean Marc Momple 14 Dec '24

Nico, Totally agree as per experience with MO-112. As there was another satellite deployed from the ISS a few minutes there was ambiguity about which is which, I confirmed same by tracking MO-112 and informed both Space Track and Dr Kelso of Celestrak and a few days after deployment all the TLE were populated correctly. Indeed if the sat operators do inform the institution and identify their bird it makes life easier for all. I take this opportunity to make an appeal to the worldwide HAM community, we all benefit a lot from free software which are voluntary huge work by the authors such as Celestrak mentioned above (there many others and the list is too long to list here) but the essential message from me is please: buy a cup for coffee for them by a donation to encourage them with such such initiatives and more continue to help our operations. I personally do donate a few $ for all software I use as these guys doing such a great work deserve a minimum of recognition from all of us using their superb tools. 73 Jean Marc (3B8DU) > On Dec 14, 2024, at 7:22 PM, Nico Janssen via AMSAT-BB <amsat-bb(a)amsat.org> wrote: > > David, > > Let me elaborate a bit on Joe's great comments. > > The source of the TLEs in the Satellite Catalog (SatCat) is the 18thSDS.

14 Dec '24

*ARISS News Release No. 24-91* *Dave Jordan, AA4KN * *ARISS PR* *dave.jordan(a)ariss-usa.org <dave.jordan(a)ariss-usa.org>* *FOR IMMEDIATE RELEASE* *ARISS Contact is Scheduled with Students at * *Zespół Szkół Łączności, Warsaw, Poland* December 14, 2024—Amateur Radio on the International Space Station (ARISS) has received schedule confirmation for an ARISS radio contact between an astronaut aboard the International Space Station (ISS) and students at the Zespół Szkół Łączności located in Warsaw, Poland. ARISS conducts 60-100 of these special amateur radio contacts each year between students around the globe and crew members with ham radio licenses aboard the ISS. Zespół Szkół Łączności (Communications School Complex) in Warsaw (about 800 students ages 14-19) consists of two schools: Technikum Łączności, a technical high school specializing in telecommunications, and XCVI Liceum Ogólnokształcące, a general education high school. A number of the school’s science clubs allow students to participate and learn more about Space communication (ZSL SPACE), telecommunication/cyber security (IT Factory Academy), and machine learning (Cisco Academy). Students have also competed in NASA Space Apps Challenge Hackathon, Moon Camp Challenge competition, CanSat competition (students designed and built a mini communication satellite, SaTech), STEM competition of Warsaw University of Technology, and Astro Pi (missions Zero and Space Lab). In preparation for the ARISS contact, the school's SP5KEU amateur radio club has been reactivated to engage students in team-based STEM projects using telecommunications and amateur radio technologies. The school's cooperation with various organizations and scientific institutions enables students to develop practical skills in real-life conditions. Members of the Amateur Radio Club (LOK) of Warsaw (SP5KAB) are supporting the school during this ARISS contact. School staff are also collaborating with the Polish Amateur Astronomy Association (PTMA) in preparation for this contact. This will be a direct contact via Amateur Radio allowing students to ask their questions of astronaut Nick Hague, amateur radio call sign KG5TMV. The downlink frequency for this contact is 145.800 MHz and may be heard by listeners that are within the ISS-footprint that also encompasses the relay ground station. The amateur radio ground station for this contact is in Warsaw, Poland. Amateur radio operators using call sign SP5KAB, will operate the ground station to establish and maintain the ISS connection. The ARISS radio contact is scheduled for December 16, 2024 at 9:35 am CET (Poland) (8:35 UTC, 3:35 am EST, 2:35 am CST, 1:35 am MST, 12:35 am PST). The public is invited to watch the live stream at: https://www.youtube.com/live/DBafZYpxolI *_______________________________* As time allows, students will ask these questions: 1. What was your first thought when you saw Earth from space? 2. How do you repair damage to the exterior of ISS caused by space debris? 3. Is it easy to fall asleep in space? 4. What was the most surprising thing you have seen or experienced that you didn't expect before the mission? 5. How do you stay healthy and fit in space? 6. How do you prepare your meals? 7. What do your family and friends say about you living in space? 8. Do you feel any changes in your body due to weightlessness? 9. What do you find challenging while living in the ISS? 10. Is it possible to take a picture of stars when the station is in sunlight? 11. What was the most unusual experiment that you have conducted? 12. Do you have any dreams related to space flights? 13. What is your most memorable moment from this mission? 14. Have you experienced situations that require quick reaction and improvising? 15. Do you have a similar or different routine for working on the ISS every day? 16. If you were to give future generations advice, what would it be? 17. What do you do in your free time? 18. What impresses you the most about being in space? 19. Does the ISS use AI to operate in space? 20. How hard is it to get used to living on the ISS? *About ARISS:* Amateur Radio on the International Space Station (ARISS) is a cooperative venture of international amateur radio societies and the space agencies that support the ISS. In the United States, sponsors are 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 promote exploration of science, technology, engineering, the arts, and mathematics topics. ARISS does this by organizing scheduled contacts via amateur radio between crew members aboard the ISS and students. Before and during these radio contacts, students, educators, parents, and communities take part in hands-on learning activities tied to space, space technologies, and amateur radio.

Re: Satellite names and TLEs
by Mark Johns, K0JM 14 Dec '24

14 Dec '24

1. The owner of the satellite generally publishes the pre-launch TLEs, which are only estimates. 2. NORAD identifies the object and assigns an object number. Sometimes, with multiple satellites on the same launch, it can take days or weeks to determine which object is which. But the object number, once assigned, remains unchanged. 3. AMSAT -- specifically, the AMSAT VP-Operations, assigns OSCAR numbers when requested to do so by the owner of the satellite. Not every owner makes this request (hence, RS-44 or LILACSAT-2, etc.). 4. Not every agency outside of amateur radio circles recognizes OSCAR numbers, and so they use the pre-launch name or something else. Keplerian elements released by AMSAT always do go by the OSCAR number, but CeleTrak and others may not. Actually, the names don't mean much. You can call a satellite anything you want. The real identifier is the NORAD object number. That's the only part of the TLE that is consistent. -- Mark D.
