IO-117 Greencube at 2400 baud and not accessible - AMSAT Italia?
by John Antonuk - AL7ID 25 Sep '23

25 Sep '23

Hi, As you may know the digipeater on IO-117 "Greencube" switched to 2400 baud a few days ago.It seems that Icom IC-9700 radios do not have sufficient transmit bandwidth to make this work. It had been announced that this switch from 1200 to 2400 was to be for 72 hours.We are now at 96 hours and counting. I have not had any luck finding contact information for the satellite operators. On the website https://www.s5lab.space/index.php/digipeater-greencube/ it is shown that AMSAT Italia helped them develop the project. Maybe somebody has a contact at AMSAT Italia that can contact University of Rome to get the status and request return to 1200 baud. thanks very much. 73, John Antonuk AL7ID(a)yahoo.com

I mounted my Arrow antenna on a bike stand to free up my hand to write the callsigns…. Some people use a camera tripod but I had limited success with that. The bike mechanics stand was a game changer for me. Only downside is that it is heavy, so going potable with it is not optimal. 73 Erik K2ERK - FN20 > On Sep 24, 2023, at 12:06, TJ Campie via AMSAT-BB <amsat-bb(a)amsat.org> wrote: > > Good morning folks, been trying to get on the birds again after a bit of a break (got a new radio that makes it a lot easier - RT3S with opengd77).

This mission marked the 85th launch of the Soyuz 2.1a in 2023 and the 6th launch from the Baikonur Cosmodrome in the same year, contributing to the 149th orbital launch attempt of 2023. The Soyuz MS-24 mission, also known as Expedition 70/71, had initially been scheduled for March 16, 2023. However, due to technical issues with the docked Soyuz MS-22 spacecraft, the crewed mission was reassigned to Soyuz MS-24. The spacecraft, designated Soyuz MS-24, carried American astronaut Loral O'Hara along with Russian cosmonauts Oleg Kononenko and Nikolai Chub. The mission launched under the auspices of the Russian space agency, ROSCOSMOS, utilizing the Soyuz 2.1a launch vehicle. The lift-off took place from Launch Complex 31/6 at the Baikonur Cosmodrome. The spacecraft's destination was the International Space Station (ISS), situated in a low Earth orbit approximately 400 kilometers above Earth's surface at a 51.66° inclination. The crew of Soyuz MS-24, upon reaching the ISS, would join the existing station crew members, which included NASA astronauts Frank Rubio and Jasmin Moghbeli, KI5WSL, Russian cosmonauts Dmitry Petelin, Konstantin Borisov, Sergei Prokopyev, as well as Denmark's Andreas Mogensen, KG5GCZ, and Japan's Satoshi Furukawa, KE5DAW. The Soyuz MS-24 crew was composed of Commander Oleg Kononenko, Flight Engineer 1 Nikolai Chub from ROSCOSMOS, and Flight Engineer 2 Loral O'Hara from NASA. Commander Oleg Kononenko, RN3DX, had previously completed four spaceflights and accumulated 916 days in space, exceeding the previous record of 878 days held by Gennady Padalka. Nikolai Chub, on the other hand, was embarking on his first journey to space as Flight Engineer 1, having been selected as a Roscosmos cosmonaut in 2012. Loral O'Hara, KI5TOM, Flight Engineer 2, was an astronaut candidate with NASA's 2017 Astronaut Candidate Class, making Soyuz MS-24 her maiden spaceflight. Soyuz, introduced in 1966, has long served as the multi-use medium-lift launch vehicle for the Soviet/Russian space program. Its versatile capabilities encompass launching civilian and military satellites, cargo, and crewed missions to the ISS. The Soyuz-2 rocket stands approximately 46.3 meters tall, with a diameter of 2.95 meters, and a total lift-off mass of about 312,000 kilograms. Its payload capacity to low-Earth orbit ranges from 6,600 to 7,400 kilograms. The Soyuz MS spacecraft, in this case, Soyuz MS-24, is the latest iteration of Russia's renowned three-person spacecraft. Although its external appearance has remained relatively consistent since its first flight in the 1960s, internal systems and capabilities have been modernized over time. The spacecraft consists of three sections: the orbital module, the descent module, and the service module. The orbital module is where the crew primarily resides while in orbit and docks with the ISS. The descent module is the section that returns to Earth intact, carrying the crew during launch and reentry. The service module houses the main engine for orbital maneuvers, thrusters for docking, and life support systems. The Soyuz MS-24 mission docked with the ISS approximately three hours and 15 minutes after liftoff, adding to the station's international crew and enabling further scientific research in the unique environment of space.

Named the "Iridium Catalysed Electrolysis CubeSat Thruster" or ICE-Cube Thruster, this innovation holds the promise of revolutionizing the propulsion systems for small satellites, particularly CubeSats, by offering a compact, efficient, and eco-friendly solution. Satellites weighing under 10 kilograms, constituting approximately 90% of today's satellite launches, present a unique set of challenges when it comes to developing components for them. Among the most critical challenges is designing rocket thrusters tailored to the limitations of CubeSats. These thrusters must not only be diminutive in size but also uncomplicated, unpressurized, low-power, and devoid of toxic materials. Funded by the European Space Agency (ESA), the ICE-Cube Thruster meets these stringent criteria, with its primary attribute being its diminutive size. The entire thruster chip, comparable in length to a human fingernail, features a combustion chamber and nozzle measuring a mere 1 millimeter. It demands a mere 20 watts of electric current to operate. A test campaign achieved 1.25 millinewtons of thrust at a specific impulse of 185 seconds. To provide a sense of scale, this thrust output is roughly half a billion times less powerful than the engines used on the Space Shuttle. However, the true innovation of the ICE-Cube Thruster lies in its propellant choice, ordinary water. Water, known for its non-explosive and non-flammable properties, is utilized as the propellant of choice. An onboard electric current induces electrolysis within the thruster, breaking down the water into hydrogen and oxygen. These gases are then fed into the combustion chamber, where they ignite, producing the necessary thrust to maneuver the CubeSat. This utilization of water as propellant not only aligns with sustainability goals but also reduces overall payload requirements. The absence of the need for pressurization in storing the propellant streamlines storage and handling systems, making them lighter and more straightforward. However, the challenge lay in fabricating the combustion chamber and nozzle for the thruster, a task that required adopting a technique akin to microelectronics. The researchers utilized Micro-Electrical Mechanical Systems (MEMS) techniques, typically used for machining silicon wafers for processors to sub-micrometer tolerances. The successful testing of the ICE-Cube Thruster was conducted through an ESA General Support Technology Programme De-Risk activity, validating its feasibility in a controlled laboratory environment. The data acquired during this testing phase will serve as a vital guide in the development of a flight-representative "Engineering Model" of the propulsion system, including the electrolyser. This development is slated to be led by URA Thrusters in collaboration with Imperial College.

The year-long testing process concluded with GOES-U proving its resilience to the harsh conditions of space, situated 22,236 miles above Earth. The testing regimen, which commenced in November 2022, involved subjecting GOES-U to extreme temperatures ranging from a scorching 188 degrees Fahrenheit (87 degrees Celsius) to a bone-chilling minus 67 degrees Fahrenheit (minus 55 degrees Celsius). This thermal vacuum testing aimed to simulate the harsh temperature fluctuations during both launch and its mission in the space environment. Following this, in February 2023, the satellite underwent vibration testing to ensure its structural integrity during the stresses of launch. It then faced the intense sounds of 138.4 decibels during acoustic testing, replicating the noise levels experienced during launch. March 2023 witnessed the successful completion of shock testing, confirming GOES-U's ability to withstand the separation from the launch vehicle and the deployment of its solar panels. Subsequently, in August 2023, electromagnetic interference and compatibility (EMI/EMC) testing ensured that the satellite's operations would remain unaffected by various forms of electromagnetic radiation. Notably, GOES-U's large five-panel solar array, initially folded during launch, was verified to deploy correctly upon reaching geostationary orbit. These solar panels will serve as the primary source of power, converting sunlight into electricity to operate the satellite's instruments, computers, data processors, sensors, and telecommunications equipment. The exhaustive testing program was conducted at Lockheed Martin's facility in Littleton, Colorado, where GOES-U was built. Simultaneously, as the satellite was being prepared for the rigors of launch and space, the GOES-U mission operations team engaged in critical rehearsals to test launch procedures and communication systems between the satellite and ground facilities. These rehearsals encompassed a wide range of scenarios, including normal operations and contingency procedures in case of unexpected events. The team also conducted tests for compatibility with the Compact Coronagraph-1 (CCOR-1) instrument, which will monitor the sun's corona as part of NOAA's Space Weather Follow-On mission. GOES-U remains on schedule for its planned April 2024 launch from Cape Canaveral Space Force Station in Florida, utilizing a Falcon Heavy launch vehicle. Following its successful journey to geostationary orbit, it will be renamed GOES-19 and undergo a series of on-orbit instrument and systems checkouts, followed by the validation of its data products. The GOES-R Series is hailed as the Western Hemisphere's most advanced weather and environmental monitoring system. Comprising four satellites, the program includes GOES-R (GOES-16), GOES-S (GOES-17), GOES-T (GOES-18), and GOES-U. These satellites play a pivotal role in providing crucial data for weather forecasts, environmental hazard detection, and monitoring solar activity and space weather. The GOES-R Series is set to operate into the 2030s. In parallel, NOAA and NASA are collaboratively working on the Geostationary Extended Observations (GeoXO) mission, ushering in the next generation of geostationary satellites to address future environmental challenges for U.S. weather, ocean, and climate operations. This collaborative effort between NOAA and NASA continues to advance environmental monitoring and scientific research from space.

The International Charter 'Space and Major Disasters,' which offers rapid support during major crises, quickly deployed Earth observation assets to assist rescue efforts. Additionally, radar measurements from Europe's Copernicus Sentinel-1 satellite mission are being utilized to assess ground shifts caused by the earthquake. This information not only aids in planning reconstruction efforts but also advances scientific research. The powerful 6.8 magnitude earthquake hit the Atlas Mountains, about 75 kilometers from Marrakesh, Morocco in an area rarely affected by such seismic events. Tragically, the earthquake resulted in significant loss of life, building collapses, and infrastructure damage. The impact was felt as far as the country's northern coast. The International Federation of Red Cross and Red Crescent Societies, along with the United Nations Institute for Training and Research, invoked the International Charter Space & Major Disasters. This initiative allows for the swift provision of satellite imagery to define the extent of the disaster, enhancing rescue operations. Satellites play a crucial role in rapid damage assessment and disaster management. Recognizing this, the European Space Agency (ESA) and France's CNES space agency established the International Charter Space and Major Disasters in 1999 to foster international collaboration in disaster response. In alignment with this collaboration, the Copernicus Emergency Mapping Service was activated to share satellite data in response to the Moroccan earthquake. High-resolution images from France's Pléiades satellites were used to create detailed damage maps, aiding rescue teams in their operations. These maps assist in identifying safe routes and bridges, ensuring the safety of responders. Philippe Bally, ESA representative of the International Charter, emphasized the urgency of delivering satellite data promptly to support relief efforts. While the response to Morocco's disaster continues, scientists are using measurements from the Copernicus Sentinel-1 mission to assess ground changes using a technique called 'interferometry.' This helps to understand the earthquake's impact and potential future hazards. The Copernicus Sentinel-1 mission's radar capabilities allow scientists to observe and analyze the precise effects of earthquakes on the land surface. This information is crucial for post-disaster restoration efforts. As Morocco works toward recovery, international space agencies and initiatives like the International Charter, alongside satellite missions such as Sentinel-1, are playing a crucial role in easing the burden on emergency responders and advancing our understanding of seismic events. These efforts contribute significantly to global disaster mitigation.

SLIM will now transition to an Earth orbit phase, where it will further test its onboard systems before embarking on its lunar journey. Simultaneously, the X-ray Imaging and Spectroscopy Mission (XRISM) also completed its critical phase, with normal operations in power generation, communication, and attitude control. XRISM is now entering a commissioning period to verify its onboard equipment's functions. These missions, launched on September 6, 2023, mark Japan's ambitious foray into lunar exploration with SLIM and its deep space investigations with XRISM, advancing our understanding of both the Moon and the universe. [ANS thanks the Japan Aerospace Exploration Agency for the above information.] + ESTCube-2 is set to launch aboard Vega C flight VV23 in the coming weeks, marking Europe's final launch of 2023. This 3U CubeSat is a joint project between the Estonian Student Satellite Foundation and UT Tartu Observatory. It will test Coulomb drag propulsion, specifically E-sails, by using a positively charged wire to deflect solar wind protons and generate thrust. Additionally, it will experiment with a plasma brake to accelerate satellite deorbiting. ESTCube-2 will also conduct tests in low Earth orbit (LEO) on an electron emitter to prepare for future deep space missions. The mission includes Earth observation (EO) payloads and materials testing for LEO's atomic oxygen environment. The team is planning a lunar mission for actual E-sailing. The Vega C launch will carry a Thai EO satellite, a Taiwanese weather satellite, and various smallsats for diverse missions such as water monitoring, tech demonstrations, IoT, and more. [ANS thanks SpaceNews for the above information.] + NASA's OSIRIS-REx mission is gearing up for a historic moment on September 24, 2023, when it will return valuable samples from asteroid Bennu to Earth, with the landing scheduled for 10 a.m. EDT (1400Z) in Utah. Launched in 2016, the mission faced unexpected challenges as Bennu's surface differed from predictions, requiring reprogramming for a successful sample collection in 2020. Inside the descent capsule is a trove of precious asteroid material. As the spacecraft enters Earth's atmosphere at high speed, it will deploy parachutes to ensure a controlled landing. This event marks the culmination of OSIRIS-REx's 7-year mission, promising crucial insights into the solar system's history and composition.

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 2023-09-23 20:30 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 2023-09-23 05:30 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 0730 - 1930 UTC. The most common times to find a crew member making casual periods are about one hour after waking and before sleeping, when they have personal time. They're usually free most of the weekend, as well. SSTV events are not that often. So please check out https://www.ariss.org/ for the latest information or watch for the ARISS announcements. And don’t forget that the packet system is active. As always, if there is an EVA, a docking, or an undocking; the ARISS radios are turned off as part of the safety protocol.
