Help Support GOLF and Fox Plus [cid:image002.jpg ＠ 01DB1748.057094F0] Join the AMSAT President's Club today and help Keep Amateur Radio in Space! https://www.amsat.org/join-the-amsat-presidents-club/ ________________________________ ARISS Slow Scan TV Transmissions Begin Tuesday ARISS is planning a Slow Scan Television (SSTV) experiment from the International Space Station, scheduled to start on Tuesday, October 8, at 16:00 GMT and running until Monday, October 14, at 14:10 GMT. [cid:image003.jpg ＠ 01DB1748.057094F0] There will be an interruption on Friday, October 11, for planned school contacts over Europe. The transmission frequency will be 145.800 MHz FM, using SSTV mode PD120. The ISS callsign will be RS0ISS. The SSTV transmissions will be made using the station in the Russian ISS Service Module. The equipment used is a Kenwood D710 transceiver running about 25 watts output which provides a very strong signal enabling reception using simple equipment. Images received by amateurs world-wide during previous transmissions can be seen at http://www.spaceflightsoftware.com/ARISS_SSTV. Amateurs can receive the SSTV pictures directly from the space station by connecting the audio output of their two-meter transceiver via a simple interface to the soundcard on a Windows PC or an Apple iOS device. On Windows PC’s the free application MMSSTV can be used to decode the signal, on Apple iOS devices you can use the SSTV app for compatible modes. For Linux systems try QSSTV. The ISS puts out a strong signal so even a 2M handheld with a 1/4 wave antenna will be enough to receive it but one's chances of success are significantly improved with the use of a handheld beam antenna. The FM transmission uses 5 kHz deviation which is standard in much of the world. Many FM rigs can be switched been wide and narrow deviation FM filters. For best results you should select the filter for wider deviation FM. Handhelds all seem to have a single wide filter fitted as standard. Reports are requested: please send ARISS uploading your decoded pictures in the official ARISS SSTV gallery: https://www.spaceflightsoftware.com/ARISS_SSTV/ Useful information to receive the pictures can be found here at https://amsat-uk.org/beginners/iss-sstv/ Follow ARISS on X for official updates during the event https://x.com/ARISS_Intl.

Purchase M2 LEO-Packs from the AMSAT Store. [cid:image005.png ＠ 01DB1748.057094F0] When you purchase through AMSAT, a portion of the proceeds goes towards Keeping Amateur Radio in Space. https://amsat.org/product-category/hardware/ ________________________________ SDRplay Announces the nRSP-ST Networked Receiver SDRplay Limited has announced the imminent launch of the nRSP-ST, an all-in-one, plug-and-play networked SDR receiver. The nRSP-ST was demonstrated publicly for the first time at the UK National Hamfest this week. (Editors Note: AMSAT News Service does not typically run new product announcements, but the nRSP-ST seems to provide satellite enthusiasts and operators with a radically new opportunity to deploy multiple stations to collect telemetry over wide-spread areas. This announcement does not constitute an endorsement by ANS.) [cid:image006.jpg ＠ 01DB1748.057094F0] This SDR addresses the needs of radio enthusiasts who want a plug-and-play solution for remote reception. In addition to providing this functionality, SDRPlay claims to have addressed typical internet bandwidth limitations with the creation of a novel “IQ Lite” mode, which delivers channels of IQ data more efficiently. The device also introduces the ability to control and store IQ recordings at the remote location. SDRPlay thinks the nRSP-ST will be ideal for anyone wanting a wideband remote receiver without needing computer skills and hours of set-up time and ongoing maintenance at the remote location. The nRSP-ST key features include: * A truly “plug and play” integrated, networked general coverage receiver that combines a receiver, a host computer and other functionality in one box. Apply power and connect to the internet (Ethernet or Wi-Fi) and the nRSP-ST is automatically accessible. * The 14-bit ADC full featured wideband SDR receiver covers all frequencies from 1kHz through VLF, LF, MW, HF, VHF, UHF and L-band to 2GHz with no gaps. * Remotely monitoring of up to 10MHz of spectrum at a time from a choice of 3 antennas. * Multi-platform SDRconnectTM software that supports local operation or remote access on Windows, MacOS or Linux platforms. * Supports multiple client connections with a simultaneous mixture of connection modes. * All modes support visualization of up to 10MHz spectrum bandwidth. * Two remote connection options: use a remote SDRconnect client or use the built-in web-server for remote access from any web browsing capable device, including Android/iOS tablets and phones. * The ability to record IQ and audio files to a NAS (network attached storage) device if available on the LAN. * Flash upgradable for future feature enhancements. * The nRSP-ST with SDRconnectTM is configurable for whatever network bandwidth is available: * In “Full IQ” mode, the nRSP-ST provides IQ data transfer of the visible spectrum bandwidth (e.g.for high-speed LAN or superfast internet connectivity). * In “IQ Lite” mode, the nRSP-ST provides IQ data of channels up to 192kHz wide (e.g. for digital decoding by the client). * In “Compact” mode the nRSP-ST provides compressed audio (ideal for slower internet connections). SDRPlay is aiming to launch the nRSP-ST in the Fall of 2024 with a price of under $500 USD.

Abstracts and papers should be sent to Dan Schultz, N8FGV at n8fgv ＠ usa.net *[ANS thanks Dan Schultz, N8FGV, AMSAT Symposium Proceedings Editor for the above information]* ------------------------------ ARISS SSTV Event Continues Until Monday October 14 ARISS is planning a Slow Scan Television (SSTV) experiment from the International Space Station started this past Tuesday and is scheduled to run until Monday, October 14, at 14:10 GMT. The transmission frequency will be 145.800 MHz FM, using SSTV mode PD120. The ISS callsign will be RS0ISS. The SSTV transmissions will be made using the station in the Russian ISS Service Module. The equipment used is a Kenwood D710 transceiver running about 25 watts output which provides a very strong signal enabling reception using simple equipment. Images received by amateurs world-wide during previous transmissions can be seen at http://www.spaceflightsoftware.com/ARISS_SSTV. Amateurs can receive the SSTV pictures directly from the space station by connecting the audio output of their two-meter transceiver via a simple interface to the soundcard on a Windows PC or an Apple iOS device. On Windows PC’s the free application MMSSTV can be used to decode the signal, on Apple iOS devices you can use the SSTV app for compatible modes. For Linux systems try QSSTV. The ISS puts out a strong signal so even a 2M handheld with a 1/4 wave antenna will be enough to receive it but one’s chances of success are significantly improved with the use of a handheld beam antenna. The FM transmission uses 5 kHz deviation which is standard in much of the world. Many FM rigs can be switched been wide and narrow deviation FM filters. For best results you should select the filter for wider deviation FM. Handhelds all seem to have a single wide filter fitted as standard. Reports are requested: please send ARISS uploading your decoded pictures in the official ARISS SSTV gallery: https://www.spaceflightsoftware.com/ARISS_SSTV/ An SSTV Award is also available. To get this award one should receive and decode at least one picture in the session. The quality of the received image does not have to be perfect, but good enough to be able to identify. Rules for earning the award are available at https://ariss.pzk.org.pl/sstv/. Useful information to receive the pictures can be found here at https://amsat-uk.org/beginners/iss-sstv/ Follow ARISS on X for official updates during the event https://x.com/ARISS_Intl. *[ANS thanks ARISS and AMSAT-UK for the above information]* ------------------------------ *2024 Coins Are Still Available!Help Support GOLF and Fox Plus.**Join the AMSAT President’s Club today!* ------------------------------ Call for ARISS Proposals from U.S. Educators The Amateur Radio on the International Space Station (ARISS) Program is seeking formal and informal education institutions and organizations, individually or working together, to host an Amateur Radio contact with a crew member on board the ISS. ARISS anticipates that the contact would be held between July 1, 2025 and December 31, 2025. Crew scheduling and ISS orbits will determine the exact contact dates. To maximize these radio contact opportunities, ARISS is looking for organizations that will draw large numbers of participants and integrate the contact into a well-developed education plan. The deadline to submit a proposal is November 17th, 2024. Proposal information and more details such as expectations, proposal guidelines and the proposal form can be found at www.ariss.org. An ARISS Introductory Webinar session will be held on Wednesday, October 16 at 7 PM ET. The Zoom link to sign up is: https://us06web.zoom.us/meeting/register/tZcpfuqpqzwiGdSZl0IXCPV6XP2OznBnaOIN The Opportunity Crew members aboard the International Space Station will participate in scheduled Amateur Radio contacts. These radio contacts are approximately 10 minutes in length and allow students to interact with the astronauts through a question-and-answer session. An ARISS contact is a voice-only communication opportunity via Amateur Radio between astronauts and cosmonauts aboard the space station and classrooms and communities. ARISS contacts afford education audiences the opportunity to learn firsthand from astronauts what it is like to live and work in space and to learn about space research conducted on the ISS. Students also will have an opportunity to learn about satellite communication, wireless technology, and radio science. Because of the nature of human spaceflight and the complexity of scheduling activities aboard the ISS, organizations must demonstrate flexibility to accommodate changes in dates and times of the radio contact. Amateur Radio organizations around the world with the support of NASA and space agencies in Russia, Canada, Japan and Europe present educational organizations with this opportunity. The ham radio organizations’ volunteer efforts provide the equipment and operational support to enable communication between crew on the ISS and students around the world using Amateur Radio.

The mission, dubbed "Flight 5" by SpaceX, lifted off from Starbase in Boca Chica, Texas, at 8:25 a.m. Eastern time. The launch represented a significant step in SpaceX's long-term goal of achieving rapid reusability for its massive Starship/Super Heavy system. The key innovation in this test was the planned recovery of the Super Heavy booster, known as Booster 12. After liftoff, the booster performed a series of precise maneuvers to guide itself back to the launch site. The booster was caught by a pair of mechanical arms-often referred to as "chopsticks"-mounted on the launch tower. About seven minutes after liftoff, the arms closed around the top of the booster, just below its grid fins, successfully completing the first-ever "catch" of a returning booster. [https://www.amsat.org/wordpress/wp-content/uploads/2024/10/SpaceX-IFT-5-Chopsticks-Booster-Catch-scaled.jpg] Final phases of Flight 5 Booster 12 catch as seen from the top of SpaceX's second Starship tower at Starbase. [Credit: @SpaceX] SpaceX officials expressed excitement over the achievement, which is critical for the company's vision of rapid reflight capability. The ability to land the booster directly on the launch pad and prepare it for another flight within days or even hours is a key component of SpaceX's goal to make space travel more efficient. "I don't know what to say!" Gwynne Shotwell, SpaceX president and chief operating officer, posted on social media along with a video of the landing, capturing the surprise and enthusiasm following the success. The mission's second stage, Starship, flew on a suborbital trajectory, reaching a peak altitude of 212 kilometers before reentering the atmosphere. Unlike the booster, Starship was not intended to be recovered. It performed a controlled splashdown in the Indian Ocean, where it exploded several seconds after touchdown. SpaceX noted improvements to Starship's heatshield from previous flights, which allowed it to survive reentry in better condition. [https://www.amsat.org/wordpress/wp-content/uploads/2024/10/SpaceX-IFT-5-Booster-Mechazilla-Arms.jpg] Super Heavy used its three center Raptor engines to precisely steer into position between the Mechazilla arms. [Credit: SpaceX] The launch came just hours after the Federal Aviation Administration (FAA) granted SpaceX an updated launch license. The revised license, issued after concerns about environmental impacts, allows SpaceX to conduct the next flight-Flight 6-without needing a new authorization. The changes to the license included adjustments to the areas where debris, such as the interstage ring, might land, and an analysis of sonic boom impacts from the returning Super Heavy booster. The environmental analysis, a requirement for the revised license, determined that there would be no significant impacts from the mission. However, SpaceX is still required to conduct monitoring and take measures to protect the local wildlife surrounding the Boca Chica site. The FAA granted SpaceX the ability to proceed with Flight 6 under the same conditions, but the company must comply with strict regulations, including submitting monitoring data and environmental reports.

The spacecraft lifted off at 12:06 p.m. Eastern Time aboard a SpaceX Falcon Heavy rocket from Pad 39A at NASA's Kennedy Space Center in Florida. The launch, described by NASA commentator Derrol Nail as unveiling "the mysteries of an enormous ocean lurking beneath the icy crust of Jupiter's moon Europa," marks the beginning of an ambitious astrobiology mission. The Falcon Heavy's 27 first-stage Merlin engines roared to life as the rocket ascended, with the two side boosters detaching about three minutes into flight. Separation of the second stage occurred shortly afterward, and Europa Clipper was deployed on its interplanetary trajectory nearly an hour later. Mission control successfully established communication with the probe, confirming that the spacecraft's solar arrays had deployed as planned, signaling a smooth start to its mission. [https://www.amsat.org/wordpress/wp-content/uploads/2024/10/NASA_Europa_Clipper_Spacecraft_Over_Moon_Europa-scaled.jpg] Artist's illustration depicts NASA's Europa Clipper spacecraft in orbit over Jupiter's icy moon Europa. [Credit: NASA/JPL-Caltech] Monday's launch faced a slight delay due to Hurricane Milton, which made landfall on Florida's Gulf Coast last week, forcing NASA to close the Kennedy Space Center temporarily. Originally scheduled for October 10, the launch was pushed back while teams secured Europa Clipper inside a SpaceX hangar near Pad 39A. This marked the 11th Falcon Heavy launch and only the second time the rocket has been used for an interplanetary mission. The Europa Clipper mission has faced a long and complex path to the launchpad. Initially, NASA intended to launch the probe using its Space Launch System (SLS), a powerful moon rocket still in development in the mid-2010s. However, repeated delays in the SLS program, along with NASA's commitment to using the early SLS vehicles for its Artemis moon missions, forced the agency to opt for a commercial alternative. A 2021 budget proposal allowed NASA to choose SpaceX's Falcon Heavy, though the shift meant the mission's journey to Jupiter would take nearly six years instead of three. [https://www.amsat.org/wordpress/wp-content/uploads/2024/10/Europa-Clipper-Solar-Array.jpg] Europa Clipper's massive solar arrays have a span of more than 100 feet (30.5 meters) when unfolded. [Credit: NASA/Kim Shiflett] At the heart of the mission is Europa, a moon thought to harbor a vast subsurface ocean beneath its icy crust. Europa has long intrigued scientists as one of the best places in the solar system to search for signs of life. However, NASA emphasizes that Europa Clipper's mission is not to find life directly but to assess the moon's habitability. The spacecraft, carrying a suite of nine science instruments, will study the composition of Europa's ocean, investigate its icy shell, and look for any signs of recent activity. After a journey of nearly six years, Europa Clipper is expected to enter orbit around Jupiter in April 2030, where it will begin an extended series of flybys of Europa. Over the course of its mission, the probe will make close passes to the moon, gathering data that could inform future missions, including a potential lander. The mission is set to conclude in 2034, with NASA planning to crash Europa Clipper into Jupiter's moon Ganymede to avoid contaminating Europa's pristine environment.

The European Space Agency's Hera mission took off on October 7, 2024, aboard a SpaceX Falcon 9 rocket from NASA's Kennedy Space Center. The mission aims to study the consequences of NASA's 2022 mission, which deliberately crashed a spacecraft into the asteroid Dimorphos, changing its orbit. The Hera mission, slated to arrive at Dimorphos and its larger companion asteroid Didymos in 2026, is expected to offer a detailed "crash scene investigation," according to European scientists. NASA's DART mission had tested whether a kinetic impact, or crashing a spacecraft into a celestial body at high speeds, could alter the object's trajectory. While neither asteroid poses a threat to Earth, Dimorphos was chosen for the experiment because of its size, which is comparable to asteroids that could potentially be hazardous in the future. [https://www.amsat.org/wordpress/wp-content/uploads/2024/10/Hera-Spacecraft-Undergoes-Vibration-Testing.jpg] Hera's main spacecraft undergoes vibration testing at ESA's ESTEC Test Centre in the Netherlands. [Credit: ESA/SJM Photography] Observations following DART's collision with Dimorphos in September 2022 revealed that the spacecraft succeeded in altering the asteroid's orbital period by about 32 to 33 minutes. However, many questions remain unanswered, such as whether the impact merely left a crater or completely reshaped Dimorphos. The Hera mission is tasked with solving these mysteries by providing detailed data on the structure and composition of both asteroids, which will further refine planetary defense strategies. Hera is scheduled to reach the Didymos system in late 2026, after a mid-March 2025 flyby of Mars to gain the necessary momentum. During the flyby, Hera will test its suite of instruments and observe Mars' moon Deimos, capturing data that will support Japan's upcoming Martian Moons eXploration mission. Once Hera arrives at the Didymos system, it will spend six weeks conducting surveys of both asteroids, using a variety of instruments to study their shapes, masses, and thermal properties. [https://www.amsat.org/wordpress/wp-content/uploads/2024/10/Hera_Milani_CubeSat_Team.jpg] The Milani CubeSat will perform close-up mineral prospecting of the Dimorphos asteroid and survey its surrounding dust. [Credit: ESA] Hera will also release two CubeSats, Juventas and Milani, to conduct more specific investigations. Juventas will use radar to probe the interior of Dimorphos, while Milani will study the mineral composition and dust environment of both asteroids. These CubeSats will communicate their findings to Hera and relay the data back to Earth, providing scientists with unprecedented insights into the double-asteroid system. Ultimately, the Hera mission could end with experimental landings on either Didymos or Dimorphos, further extending its ability to study the asteroids up close. Scientists hope the data collected will deepen understanding of how asteroid deflection technology can be used to protect Earth from future threats. As Patrick Michel, principal investigator of the Hera mission, noted, while DART was a success, Hera will complete the story by offering crucial details that could inspire future planetary defense initiatives.

The booster emitted sparks and debris, but the rocket continued its ascent and reached orbit. This mission is part of the certification process for the Vulcan rocket, which will soon carry national security payloads for the U.S. Space Force and the National Reconnaissance Office (NRO). ULA included a dummy payload and technology experiments to gather data and validate the rocket's performance. The booster issue is under investigation, but the key mission objectives were met, according to ULA CEO Tory Bruno. The Vulcan rocket, powered by Blue Origin's BE-4 engines, will replace ULA's Delta 4 and Atlas 5 rockets, positioning the company for future success in the competitive space market. (ANS thanks Spaceflight Now for the above information) + Four astronauts aboard the International Space Station (ISS) are awaiting their return as mission managers monitor unfavorable weather conditions off the coast of Florida. The Crew-8 mission, which includes NASA astronauts Matthew Dominick, Mike Barratt, and Jeanette Epps, along with Roscosmos cosmonaut Alexander Grebenkin, is nearing its conclusion after seven months in space. While they prepare for their journey home, the crew spent the week relaxing and engaging in pre-departure activities. A weather briefing occurred on Wednesday, October 16, at 11 a.m. EDT, assessing conditions for their splashdown. Mission managers are now targeting a new undocking time of no earlier than 3:05 a.m. EDT on Sunday, October 20. (ANS thanks SciTechDaily for the above information) + The FAA authorized SpaceX to resume Falcon 9 flights on October 11, following a suspension caused by an upper stage anomaly during the Crew-9 mission on September 28. The anomaly occurred when the Merlin engine burned 500 milliseconds longer than planned, resulting in reentry outside its designated zone. SpaceX conducted an investigation, and the FAA approved their corrective actions, though neither disclosed specific details of the findings. A special exception had been made for the European Space Agency's Hera mission on October 7, as it posed no public safety risk. With the issue resolved, Falcon 9 operations fully resumed on October 15. SpaceX marked its return with a double Starlink mission, launching from both Vandenberg and Cape Canaveral on the same day. (ANS thanks SpaceNews for the above information) + Following Hurricane Helene, T-Mobile and Starlink activated their satellite texting service in preparation for Hurricane Milton to ensure Florida residents could stay connected despite potential cellular outages. After the Federal Communications Commission granted emergency approval, the service enabled T-Mobile users to send and receive basic texts, including 911 messages, even if the network went down. Starlink's Direct to Cell satellites were also employed to send emergency alerts to all phones and carriers in the affected areas. Users could determine if their phone connected to a Starlink satellite by the presence of one to two bars of signal and the network name displaying "T-Mobile SpaceX." The satellite service worked best outdoors or near windows, although users sometimes had to retry sending messages if they didn't go through on the first attempt. SpaceX has also delivered over 10,000 Starlink kits in response to Hurricane Helene, as part of ongoing recovery efforts.

After some delay, the microwave transponder should be available soon. The concept was presented at the AMSAT annual symposium on two successive years. The design has not changed significantly since then. See https://catsat.arizona.edu for current info. The project was run by the University of Arizona students with major support by Rincon Research Corp. (onboard DSP and HF electronics) and FreeFall Aerospace (patch, HF whip, and high-gain 10 GHz. inflatable antenna.) The spacecraft bus was supplied by Gomspace. Something strange happened during launch or satellite deployment, and the satellite is believed to be damaged by an unknown mechanism. The UHF command and control antenna appears not to have deployed and the main spacecraft computer reboots an irregular pattern. The student team has done an excellent job of keeping the spacecraft under control while troubleshooting the problems, but this has slowed the commissioning process. CatSat with inflated spherical microwave antenna *[Artist’s rendering: University of Arizona]* *SATELLITE MODES OF PARTICULAR INTEREST TO HAMS* 1. The HF experiment (also known as the WSPR experiment) captures the entire HF band by sampling it with a 50 MHz analog to digital converter. Digital processing in an FPGA creates up to four sub-bands which are stored in CatSat memory. The tuned frequency and bandwidth of these four receivers will likely be changed from time to time on a schedule to be determined. Then the captured pre-detection data will be stored in CatSat’s AstroSDR memory until it can be dumped to our 6.1 meter dish in Tucson. There the sub-band data streams will be extracted and placed on the internet where interested hams will have access. The intent is to provide an opportunity for hams to experiment with ionospheric propagation as viewed by a satellite without having to actually build a ground station. If they work HF stations using FT-8 or WSPR when the satellite is active they will be able to use the internet to access what the satellite was hearing. They may even discover some novel propagation mechanism. 2. At the start of each data capture 32k samples of I-Q data will be captured at 50 MHz sample rate. These data can be Fourier transformed to create a spectral power plot of the entire HF band at that location. 3. The 10 GHz downlink modulation is DVB-S2. At the time of planning the downlink, there was a lot of AMSAT interest in using DVB-S2 as a downlink modulation for proposed high orbit birds. That drove our decision. Receiving this link will be a challenge for most stations, unless the inflatable antenna experiment is successful and we point that antenna at your location. 4. 5.663 GHz to 10.47 GHz transponder with 200 kHz Bandwidth. During design review of CatSat it was realized that there was space for an additional 5 GHz patch antenna on the spacecraft. The AstroSDR could receive 5.663 GHz and translate it to the IF input of the 10.47 GHz transceiver. So a 200 KHz linear transponding mode was added. It is one of the first ham satellites to use these microwave bands.

The changes are intended to make it easier for the growing U.S. commercial space industry to expand sales while also protecting national security and foreign policy interests. Certain items involving remote sensing spacecraft or space-based logistics assembly, and servicing spacecraft will no longer need licenses for shipment to Australia, Canada, and the United Kingdom, the Commerce Department said in the statement. Some less sensitive satellite and spacecraft parts and components will no longer require licenses for shipment to over 40 countries. The countries include Canada, Australia, Japan, South Korea and most of the European Union, a person familiar with the matter said. In addition, the Commerce Department will do away with license requirements for the least sensitive items like electrical connectors for most of the world, but not countries of concern like Russia and China, the person said. A proposed rule also was published regarding the transfer of jurisdiction of certain space-related defense articles from the State Department to the Commerce Department, making it easier to export them to close allies and partners. The rules come after a proposed rulemaking nearly five years ago and a December 2023 National Space Council request.

Intelsat confirmed the news in a press release on Oct. 21, declaring the satellite a “total loss.” The U.S. Space Force said it is tracking around 20 associated pieces but “has observed no immediate threats” to other satellites so far (Roscosmos said it was tracking 80 fragments). The cause of the explosion is not yet known, but the news is another blow for Boeing following Starliner’s failed crew test flight, problems with the 737 Max and delays to the 777x. Intelsat said it’s working to move customers to its other satellites or third party spacecraft. “A Failure Review Board has convened to complete a comprehensive analysis of the cause,” the company wrote. The satellite was uninsured, a spokesperson told SpaceNews. EpicNG* [Artist’s rendering: Intelsat]* The explosion fragments could still pose a risk to other satellites. “The problem is that there is a lot of uncertainty regarding the orbits of these fragments at the moment,” said a spokesperson for Spaceflux, a UK company that tracks objects in orbit. “They can be potentially dangerous for other satellites but we do not know that yet.” Intelsat 33e is one of six “EpicNG” satellites built by Boeing, and uses the latter’s 720MP satellite platform equipped with 16 hydrazine-powered engines built by Aerojet Rocketdyne. The type is widely used for telephone, internet and satellite TV/radio broadcast services. It entered service three months late due to an issue with its primary thruster, and another propulsion issue reduced its service life by 3.5 years. The first EpicNG satellite, Intelsat 29e, was declared a total loss in 2019 after just three years in service, reportedly due to a meteoroid impact or wiring flaw.

New bulletin files will be posted immediately after reliable elements become available for new amateur satellites.

This is the future that Reflect Orbital imagines is possible. The startup is developing satellites that would deploy large mirrors to precisely reflect sunlight onto specific points on the ground. Rings of satellites in sun-synchronous orbit would follow the terminator, or the line that separates night and day, providing additional sunlight before dawn and after dusk. Illustration of illuminated sites* [Image: Reflect Orbital]* According to Reflect’s two co-founders, CEO Ben Nowack and CTO Tristan Semmelhack, this extra sunlight could increase the amount of solar power delivered to the electricity grid. Instead of building more solar farms, the pair thinks we can simply increase the amount of power generated at the ones that already exist. The pair say they are still playing with the final configuration for its production-scale vehicles, like the exact size of the reflective array or the final number of satellites that will make up the constellation. But they are starting small, and the first orbital mission will fly a subscale prototype with a reflector that’s 10 by 10 meters. Many of the debunking videos cite the 10 by 10 meter figure, which is too small to reflect an economically meaningful amount of sunlight on the ground. A news article from earlier this year also said that the constellation will be just 57 satellites. But Semmelhack said these figures are inaccurate; 57 satellites ringing Earth will guarantee a half hour of service twice per day, once in the morning and once in the evening, the minimum to achieve the plans to “extend the day.” The pair also say that 10 by 10 meters is “just a starting point”: Full-scale production vehicles will deploy arrays that are much larger, around 50 by 50 meters or bigger, with the planned constellation growing to “thousands to tens of thousands” of satellites. “The 10 by 10 is our demonstration that will be brighter than a full moon, roughly 400,000 times less bright than the sun at noon,” Nowack explained over email. “Our production service is targeting 1/5 noon sunlight brightness and will use 100’s ? 1000’s of larger vehicles focused at one spot. A 50 by 50 satellite is actually on the small end.” But even given these additional details, the satellites would still need to be capable of maintaining highly precise control over their mirrors on orbit, and do this across many thousands of satellites. It will be a huge challenge.

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 also ACTIVE (145.825 MHz up & down). Ham TV and SSTV systems are currently 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. 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 The latest list of frequencies in use can be found at https://www.ariss.org/contact-the-iss.html [ANS thanks Charlie Sufana, AJ9N, one of the ARISS operation team mentors for the above information] ------------------------------ Upcoming Satellite Operations Guyana: Aldir, PY1SAD (ZZ1M), operates from Georgetown as 8R1TM between Oct. 12 and Nov. 24 on 160-10m (CW, SSB, digital modes) and via satellites. QSL via LoTW, eQSL, qrz.com. (From DXNL 2427 ? October 9, 2024) 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.

AMSAT Ambassador Program, for the above information] ------------------------------ Satellite Shorts From All Over + HADES-D (SO-121) is decaying fast so it will only last a few days. Current height is near 355 km. Control operators are manually turning on the internal amplifier, so some passes could be in high power, depending on the zone. This has to be done each day because the on board computer is resetting this configuration each 24 hours. (ANS thanks Félix Páez, EA4GQS, of AMSAT-EA for the above information.) + In addition to SO-121 (above), UVSQ-Sat, XW-2D and XW-2B are predicted to decay from orbit within days or weeks. (ANS thanks AMSAT-AR [ http://lu7aa.org/reenter.asp] for the above information.) + The ARRL has released LoTW configuration file version 11.29 adding support for QSOs via MESAT-1 (as MO-122) and SONATE-2 (as SONATE). (ANS thanks ARRL for the above information.) + FUNcube (AO-73) is now in Autonomous mode, meaning high power telemetry when in daylight, and transponder in when the satellite is in eclipse. Controllers are watching the effect on its 11 year old batteries. If the batteries suffer badly they will revert to Eclipse mode. All telemetry will be gratefully received ? see http://data.amsat-uk.org/ui/fc1-fm for details. (ANS thanks David Johnson, G4DPZ, Honorable Secretary, AMSAT-UK, of the FUNcube Team for the above information.) + Crew-8 members, NASA astronauts Matthew Dominick, KCØTOR, Michael Barratt, KD5MIJ, Jeanette Epps, KF5QNU, and Roscosmos cosmonaut Alexander Grebenkin, RZ3DSE, all woke up late on Oct. 21, having shifted their sleep schedules in anticipation of Monday’s departure from the International Space Station. However, they spent the rest of the day continuing their daily exercise routines and standard housekeeping tasks aboard the orbiting lab. NASA and SpaceX officials delayed the undocking until late Wednesday, Oct. 23 due to unfavorable weather conditions near the multiple splashdown zones off the coast of Florida. Splashdown was early Friday, Oct. 25. During routine medical assessments on the recovery ship, an additional evaluation of the crew members was requested out of an abundance of caution. One crew member remained hospitalized Friday evening. (ANS thanks NASA for the above information.) + NASA will use SpaceX’s Crew Dragon for its two crew rotation missions to the International Space Station in 2025 as it continues to evaluate if it will require Boeing to perform another test flight of its Starliner spacecraft. In an Oct. 15 statement, NASA said it will use Crew Dragon for both the Crew-10 mission to the ISS, scheduled for no earlier than February 2025, and the Crew-11 mission scheduled for no earlier than July. Crew-10 will fly NASA astronauts Anne McClain and Nichole Ayers along with astronaut Takuya Onishi from the Japanese space agency JAXA and Roscosmos cosmonaut Kirill Peskov. NASA has not yet announced the crew for the Crew-11 mission. (ANS thanks SpaceNews for the above information.) + The Mauritius Amateur Radio Society (MARS) portable team, on Oct. 20, enabled many young Scouts of the Mauritius Scout Association (MSA) to communicate with other Scouts around the World on QO-100 GEO satellite.
