Ariane 5 Rockets into Retirement: Europe's Workhorse Completes Final Mission



Europe's workhorse rocket has completed its final mission, launching two satellites into orbit before retiring after an illustrious 27-year career. The Ariane 5, known for its power and reliability, took off from Europe's Spaceport in Kourou, French Guian




a on July 5, marking its 117th and last orbital liftoff.



The mission commenced at 6 p.m. EDT (2200 GMT), with the Ariane 5's 103-foot tall solid rocket boosters separating from the core stage approximately 2.5 minutes into flight. The core stage, powered by a single engine, continued its ascent, carrying the tw




o satellites onboard. At around nine minutes after liftoff, the core stage shut down, and the upper stage separated to initiate its own burn. About 30 minutes into the flight, the first satellite, Heinrich-Hertz, was released into geostationary transfer o




rbit. Shortly after, the second payload, Syracuse 4B, followed suit.



Stéphane Israël, CEO of Arianespace, the France-based company operating the rocket, hailed the Ariane 5's flawless performance during the launch webcast. Israël described the rocket as a "legendary launcher" that had completed its work perfectly.



Heinrich-Hertz, an experimental communications satellite managed by the German space agency (DLR), will serve as a test platform for new hardware and conduct scientific and technical experiments in collaboration with universities and public sector organiz




ations. This satellite represents Germany's first dedicated technology demonstration and communications research spacecraft.



Syracuse 4B, joining its predecessor Syracuse 4A launched in 2021, was built by Airbus Defence and Space for the French government. Both satellites are military communication relays, replacing Syracuse satellites 3A and 3B.



To reach geostationary orbit, located approximately 22,200 miles (35,800 kilometers) above Earth, Heinrich-Hertz and Syracuse 4B will perform a series of engine burns.



The retirement of Ariane 5 draws the curtain on its nearly 30-year operational career, during which it outperformed its predecessors, making it the most successful Ariane rocket to date. The European Space Agency (ESA) highlighted the rocket's technical p




rowess and reliability, describing it as a major asset for Europe's autonomous access to space.



Arianespace, in collaboration with ESA and the French space agency CNES, operated the two-stage Ariane 5, which was built by Airbus Defence and Space. Over the years, the rocket underwent several upgrades and operated in five different configurations. The




 most recent versions, Ariane 5 EC/A and ES, started operating in 2009, succeeding the Ariane G5, which flew from 2005 to 2009 after the brief G+ version and the original Ariane 5 G.



Although the Ariane 5 encountered an initial failure during its debut launch in 1996, failing to reach orbit and initiating an auto-destruct abort mid-flight, it went on to become one of the most reliable launchers worldwide. According to ESA, the rocket 




achieved a 96% success rate across its 117 missions and delivery of 239 payloads to orbit.



The development of the Ariane 5's successor, the Ariane 6, has been in progress for over a decade. The new rocket aims to be more flexible, cost-efficient, and capable of serving various types of launches compared to its predecessor. It will come in two c




onfigurations: A62, with two solid rocket boosters, and A64, with four. Originally slated for a 2020 debut, the Ariane 6 has faced delays, with the current estimate pointing to alate 2023 launch. This delay leaves Europe with a temporary gap in launch opt




ions until the Ariane 6 becomes operational.



To ensure continuity in European programs, the European Space Agency (ESA) has explored alternative launcher options from a technical, schedule, and security standpoint. In April, there were reports that the European Commission was considering using a Spa




ceX Falcon Heavy rocket to launch some of the European Union's Galileo navigation satellites, rather than waiting for the Ariane 6. However, ESA officials emphasized that Ariane 6 remains the preferred launch option for European missions requiring a heavy




 launch vehicle, and they are working diligently to ensure its inaugural flight.



The final mission of the Ariane 5 was initially scheduled for June 16 but faced delays. The first attempt was scrubbed due to issues with the solid rocket boosters' pyrotechnical transmission lines, while the second attempt on July 4 was hindered by unfav




orable weather conditions.



As Europe bids farewell to the Ariane 5, the spotlight now shifts to the eagerly anticipated Ariane 6, which promises to usher in a new era of flexibility and cost efficiency in space launches. In the meantime, efforts continue to bridge the launch gap an




d maintain the continuity of European space programs.

CubeSats Deploy from ISS: Nanoracks Mission Advances Science and Education



NASA astronaut Stephen Bowen successfully deployed six CubeSats into low-Earth orbit outside the ISS Kibo module airlock on July 6th. The deployment was made possible by Nanoracks, a leading provider of commercial space services, who had been preparing fo




r this mission named NRCSD-26. Sponsored by the ISS National Lab, the mission carried five CubeSats developed by Canadian universities, as well as a groundbreaking project by The Aerospace Corporation. Nanoracks, in collaboration with the Canadian Space A




gency, handles the integration and deployment of these satellites from the ISS. The six CubeSats were transported to the ISS on SpaceX's CRS-28 mission.



This deployment marks an important milestone for the Canadian CubeSat Project (CCP), a collaboration between Nanoracks and the Canadian Space Agency (CSA). The objective of the CCP is to launch a CubeSat from each province and territory in Canada. The dep




loyment of these CubeSats serves scientific purposes while also promoting hands-on experience and generating interest in STEM studies and careers.



The selected CubeSats for the NRCSD-26 mission represent a diverse range of scientific objectives, showcasing the capabilities and interests of Canadian universities.



One of the CubeSats, RADSAT-SK developed by the University of Saskatchewan, aims to test a radiation detection system and evaluate the effectiveness of radiation protection using a purified form of melanin, a natural pigment found in various organisms. An




other CubeSat, ESSENCE from York University, focuses on monitoring solar storms, arctic ice, permafrost thaw, and forests in the Canadian Arctic region. It also aims to demonstrate satellite attitude recovery in the event of a failure in one of its actuat




ors. Ukpik-1, developed by Western University, carries a virtual reality (VR) camera to capture 360-degree images and videos of Northern Canada. This CubeSat not only contributes to scientific research but also facilitates educational outreach and public 




engagement in Ontario and Nunavut.



The University of Manitoba's CubeSat, IRIS, is designed to observe the weathering of geological samples under direct solar and background cosmic radiation, aiming to detect any visually detectable changes that may occur over short time scales. SC-ODIN, de




veloped by Concordia University, has the primary mission of collecting data on dust storms in Argentina and Namibia. Additionally, it monitors radiation received inside and outside the satellite over a period, providing valuable insights into radiation ex




posure in space.



In addition to the Canadian CubeSats, Nanoracks also deployed Moonlighter, built by The Aerospace Corporation. Moonlighter is a 3U CubeSat and holds the distinction of being the world's first hacking sandbox in space. Its purpose is to advance the underst




anding of cybersecurity as it pertains to space systems. The CubeSat will be utilized at the DEFCON conference by the Air Force/Space Force, where cybersecurity professionals will be challenged to hack a real-life satellite. For more information on Moonli




ghter and the Hack-a-Sat challenge, visit the official website at https://hackasat.com/.

ROSCOSMOS Successfully Deploys Forty-Three Satellites in Latest Soyuz 2.1b Launch



ROSCOSMOS successfully launched the Meteor-M2-3 meteorological satellite and a cluster of 42 accompanying satellites on June 27, 2023. The launch took place at the Vostochny Cosmodrome in the Amur Oblast region of Russia, marking the 14th launch from this




 site.



The Meteor-M2-3 satellite is part of the Meteor-M series, which aims to modernize Russia's national meteorological satellite system. Developed by NPP VNIIEM and sponsored by ROSCOSMOS, the series is designed to enable climate and environmental monitoring,




 exploration of Earth's natural resources, surveillance of solar activity, and data acquisition from automated data collection platforms. The satellite also features the COSPAS-SARSAT search and rescue system.



Meteor-M2-3 is equipped with advanced instruments, including an onboard radar complex based on an active phased array antenna, a shortwave reflected radiation meter, and a radio frequency mass spectrometer. These instruments enable all-weather radar surve




illance of the Northern Sea Route and broaden the range of monitored parameters. The satellite has a lifespan of five years and is equipped with two deployable solar arrays.



In addition to the Meteor-M2-3 satellite, the mission carried various accompanying satellites. Sixteen CubeSats from the Space-Pi project were deployed into orbit as part of an agreement between ROSCOSMOS and the Innovation Promotion Fund of Russia. Nine 




satellites from the UniverSat program, led by ROSCOSMOS, were also launched, along with seventeen SmallSats for commercial customers.



The launch vehicle used for this mission was the Soyuz 2.1b rocket, belonging to the Soyuz 2 rocket family. The Soyuz rocket has been a reliable workhorse of the Soviet/Russian space program since its introduction in 1966. The Soyuz 2.1b variant stands ap




proximately 152 feet (46.3 meters) tall and has a diameter of 9 feet (2.95 meters). It consists of three stages, all of which are expendable.



The first stage of the Soyuz 2.1b rocket includes four side boosters powered by RD-107A engines. These boosters perform the iconic "Korolev cross" pattern during separation. The center core stage is propelled by a single RD-108A engine, while the upper st




age is equipped with a single RD-0124 engine. Both engines run on rocket-grade kerosene (RP-1) and liquid oxygen (LOx).



The mission did not involve the recovery of the first stage or fairings, as the Soyuz rocket does not possess such capabilities. The first stage of the rocket landed in the Zeysky District of Amur Oblast, Russia.



This launch marked several milestones: it was the 115th flight of an upper stage from the Fregat family, the first launch of a Soyuz 2.1b rocket in 2023, the 80th launch of a Soyuz 2.1b variant, and the 96th orbital launch attempt of 2023.



With the successful launch of the Meteor-M2-3 satellite and its accompanying payloads, ROSCOSMOS continues to enhance Russia's meteorological satellite system and expand its capabilities in climate monitoring, resource exploration, and search and rescue o




perations.

Meteor-M2-3 Weather Imaging Satellite Now in Orbit and Transmitting Images



The latest addition to the Meteor-M satellite series, Meteor-M2-3, has successfully reached orbit and is already transmitting images of Earth. The Russian-owned weather imaging satellite was launched on a Soyuz-21.b rocket on June 27th. Previous iteration




s of the Meteor-M satellites faced premature mission terminations due to technical glitches or collisions with micro-meteorites.



Meteor-M satellites operate in a polar orbit, capturing and transmitting weather images in the LRPT format at a frequency of 137 MHz. This frequency range makes the reception of their signals as accessible as that of the older NOAA APT satellites. To rece




ive these images, an appropriate 137 MHz satellite antenna is required, such as a V-Dipole, Turnstile, or QFH, along with a compatible software-defined radio (SDR) receiver like the popular RTL-SDR.



One of the recommended software options for receiving images from the Meteor-M2-3 satellite is SatDump. This user-friendly software offers binary releases for Windows and Android platforms, downloadable from SatDump GitHub Releases page: https://github.co




m/SatDump/SatDump/releases. Linux users can consult the SatDump Readme for a comprehensive build guide. It is worth noting that the SatDump graphical user interface has been reported to perform well on an Orange Pi 5, providing a convenient and portable s




olution for image reception.



To determine when the satellite is over your location you can use satellite tracking software such as Gpredict for Linux and Mac users, or Orbitron for Windows users. When utilizing Orbitron, it is important to run the software as an Administrator and upd




ate the Two-Line Elements (TLEs) to include the tracking data for the Meteor-M2-3 satellite found in the weather.txt TLE file. Consult the Meteor-M2-3 TLE (Two-Line Elements) available on Celestrak's website for precise tracking and monitoring.



Many satellite enthusiasts have already shared their successful reception of Meteor-M2-3's images to Twitter. The author of SatDump has revealed that work is underway to finalize projections for Meteor M2-3, and this should be ready to use in SatDump shor




tly. SDR++ software has now also integrated a Meteor Demodulator, further expanding the options available to those interested in receiving data from Meteor-M2-3.



Recent updates on Meteor-M2-3's progress from Happysat (https://github.com/happysat) indicate that telemetry data received on July 3rd suggests that the satellite's LRPT antenna might not have unfolded correctly, resulting in weaker-than-expected signals.




 It has also been reported that the satellite switched from transmitting on a frequency of 137.900 MHz to 137.100 MHz on July 4th, 2023.

UMKA-1 School Satellite Sets Out to Explore the Skies



The UMKA-1 satellite, developed by schoolchildren from the Moscow Regional Educational Institution Secondary School No. 29 named after P.I. Zabrodin (Podolsk) in collaboration with SPUTNIKS LLC, was successfully launched into orbit on June 27, 2023. As pa




rt of the "Space-π" program and with the support of the Innovation Assistance Fund, UMKA-1 aims to train young students in spacecraft design, programming, and assembly, while also conducting astronomical observations using its high-aperture telescope, Le




ptonar-20955K.



The UMKA-1 satellite is a 3U+ CubeSat equipped with a Leptonar-20955K optical telescope and an astronomical digital camera called PlayerOne Saturn-C SQR. This compact satellite operates in two frequency bands, with telemetry transmission taking place on t




he UHF downlink frequency of 437.625 MHz, using GMSK USP modulation scheme at a rate of 2400 baud. Additionally, the transmission of data from the telescope occurs on the S band at a frequency of 2402 MHz. On June 18th, 2023, UMKA-1, known by its designat




ed callsign RS40S, obtained its IARU Amateur Satellite Frequency Coordination.



Named after a beloved Soviet cartoon character, UMKA-1 carries the spirit of adventure and discovery. The mission team plans to share the main course of their mission, interesting events from the ground segment, and a transmission schedule on the S band w




ith the wider community. Once the satellite is fully operational, a schedule will be published, and opportunities will be provided for the reception of images from the telescope.



Despite some minor setbacks during the installation process, the UMKA-1 team remains dedicated to the success of their mission. The initial format installation confusion has been addressed, and the satellite is currently undergoing testing. The team expec




ts the telescope to be fully operational by the end of July, following which a transmission schedule will be made available.



Alexey Shafiev, RA3PPY, expressed gratitude to SPUTNIX for their support and guidance throughout the project. He acknowledged the enthusiasm and efforts of the young schoolchildren and students who form the bulk of the team. Their passion for space explor




ation is evident, and they have been actively involved in every aspect of the project.



In the past week, the telemetry transmission format was updated to use GMSK USP 2400 baud. The Mission Control Center (MCC) team will next focus on stabilizing the spacecraft and ensure the proper functioning of the guidance system. Subsequently, a two-we




ek testing period for the payload will commence before UMKA-1 can fulfill its educational mission.



The UMKA-1 team assures the community that updates on their progress will be provided as soon as possible. Despite their current work rush, they value the interest and support from all those following their mission. Alexey, on behalf of the team, promises




 to respond to all the emails received thus far in the near future.



As of July 4, 2023, UMKA-1 remains operational in orbit, transmitting telemetry data pertaining to the satellite's operation. The team has made available a tool for decoding S band dump transmissions from the spacecraft, allowing enthusiasts to access the




 images collected by UMKA-1.



For radio amateurs keen on participating in the mission, the UMKA-1 team offers a QSL card as recognition for receiving telemetry from the satellite. To qualify, individuals must receive three packets of telemetry data and upload the collected information




 to the QSL card application form found at https://r4uab.ru/diplomnye-programmy-i-qsl/mka-umka-1/ within 24 hours of receiving the last telemetry package. The required software for receiving the telemetry information, such as "SoundModem USP" and "AGW Cli




ent R4UAB," is available to facilitate the process.



The UMKA-1 mission is an exciting endeavor that combines education, amateur radio, and scientific exploration. By encouraging young minds to explore the wonders of space, this project aims to inspire the next generation of scientists, engineers, and astro




nomers. The UMKA-1 team invites everyone to join them on this incredible journey as they unlock the secrets of the universe through their school telescope satellite.



More detailed information about the UMKA-1 satellite is available at https://sputnik.school29.ru/radio/. Individuals can visit the project's GitHub repository at https://github.com/radio-satellites/UmKa-1/ to obtain the software needed to decode the S ban




d dump transmissions, which contain high resolution imagery from the telescope on board the satellite.

Changes to AMSAT-NA TLE Distribution for July 7 2023



Two Line Elements or TLEs, often referred to as Keplerian elements or keps in the amateur community, are the inputs to the SGP4 standard mathematical model of spacecraft orbits used by most amateur tracking programs. Weekly updates are completely adequate




 for most amateur satellites. Elements in the TLE bulletin files are updated daily. TLE bulletin files are updated to add or remove satellites as necessary Thursday evenings around 2300 UTC, or more frequently if new high interest satellites are launched.




 More information may be found at https://www.amsat.org/keplerian-elements-resources/



This week there are no additions or deletions to the weekly AMSAT TLE distribution.

ARISS NEWS



Amateurs and others around the world may listen in on contacts between amateurs operating in schools and allowing students to interact with astronauts and cosmonauts aboard the International Space Station. The downlink frequency on which to listen is 145.




800 MHz worldwide.



UPCOMING:

Due to summer school holidays, no contacts currently scheduled.



The crossband repeater continues to be active (145.990 MHz up {PL 67} & 437.800 MHz down). If any crewmember is so inclined, all they have to do is pick up the microphone, raise the volume up, and talk on the crossband repeater. So give a listen, you just




 never know.



The packet system is also active (145.825 MHz up & down).



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

Upcoming Satellite Operations



Mitch AD0HJ will be roving six Western Kansas grids from July 14 through July 16. Look for him on the DM99/EM09 grid line on Friday, DM97/DM98 grid line on Saturday, and the EM07/EM08 grid line on Sunday. The best chance for contacts will be the afternoon




 RS-44 passes (1900Z to 2330Z) but he will also work the late shift with QSOs on the activated TEVEL satellites in the evenings (0230Z to 0500Z) except for Sunday where he will work the noon time (1600Z to 1800Z) TEVEL passes. Follow Mitch @AD0HJ on Twitt




er for updated rove information, https://aprs.fi/AD0HJ to track his location, and https://hams.at for the latest pass schedule.



To include your satellite roving plans in the AMSAT News Service Weekly bulletins, send them to Ian, K5ZM at k5zm (at) comcast (dot) net at least a couple of weeks in advance. Upcoming satellite operations are updated weekly on the AMSAT Upcoming Satellit




e Operations page but may expire before the next AMSAT News Service bulletin is released. You can watch for the latest roving information to become available at https://www.amsat.org/satellite-info/upcoming-satellite-operations/.



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.

Satellite Shorts From All Over



+ Congratulations to our latest GridMaster Award winners: Steve Nordahl, NS3L (#58) and Bill Attwood, VE6WK (#59). The GridMaster Award, AMSAT's most prestigious recognition, is available to amateur radio operators worldwide who establish two-way satellit




e communication with all 488 maidenhead grids within the contiguous United States. Contacts must be made from the same location or from locations within a 100-kilometer radius of a single location. Written confirmation, such as QSL cards or Logbook of the




 World (LoTW), is required. The GridMaster application and certificate fees have been underwritten by an anonymous donor. More information about this award can be found on the AMSAT website at https://www.amsat.org/gridmaster/. Congratulations again to Bi




ll VE6WK and Steve NS3L for their remarkable accomplishments! (ANS thanks Bruce Paige, KK5DO, AMSAT Director of Contests and Awards for the above information)



+ Congratulations the following individuals on receiving the AMSAT Rover Award for their outstanding achievements in portable satellite operating: Olivier Tymkiw HB9GWJ (#077), Erwin Vink PA3GAN (#078), Doug Keech VA7LM (#079), and Bruce Patten VE7PTN (#0




80). To qualify for this award, they accumulated a minimum of 25 points by activating grid squares beyond their home grid. Points were earned through various achievements, including activating states, provinces, or DX entities outside their home location 




via satellite, as well as promoting their grid operations through social media and documenting their activations through photographs and published articles. More information about this award can be found on the AMSAT website at https://www.amsat.org/amsat




-rover-award/. Congratulations to our esteemed AMSAT Rover Award recipients! (ANS thanks Bruce Paige, KK5DO, AMSAT Director of Contests and Awards for the above information)



+ Quetzal-1, a 1U CubeSat developed by Universidad del Valle de Guatemala operated successfully for two hundred and eleven days in-orbit a few years ago. The project just released a massive trove of open-source design documents, the software that ran on t




he satellite and ground station, and all the captured telemetry from the flight. Its the ultimate bootstrap for anyone else designing a CubeSat, and hopefully provides enough clues to avoid some of the same issues. And if you want the details on the Qu




etzal-1 design, and what went wrong with the electrical system, two PDF papers have been released. Seeing more open source in space is an encouraging development, and one that should continue to grow as the cost of payloads to orbit continues to fall. Inf




ormation on Quetzal-1 CubeSat can be found at http://github.com/Quetzal-1-CubeSat-Team. (ANS thanks Hackaday.com for the above information)



+ Youth on the Air Camp 2023 is a camp for young amateur radio operators in North, Central and South America. Campers will operate the special event station VE3YOTA while camp is in session with a special focus on satellite operations occurring Wednesday,




 July 19 from 1400Z to 1700Z (10 a.m. to 1 p.m. EDT). Additionally, an ARISS contact with the International Space Station is scheduled to take place on Tuesday, July 18 at 1842Z (2:42 p.m. EDT). For more information about the camp, please visit YouthOnThe




Air.org or contact Camp Director Neil Rapp at director@youthontheair.org. (ANS thanks Neil Rapp, WB9VPG for the above information)
