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
Guiana 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
two 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 orbit. 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
organizations. 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
prowess 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
configurations: 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
options 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
SpaceX 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
unfavorable 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
and 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
for 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 Agency, 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
deployment 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.
Another 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
actuators. 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,
developed 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
exposure 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
understanding 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

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
surveillance 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
approximately 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
stage 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
operations.

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
iterations 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
receive 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.
com/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 solution 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
update 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
shortly. 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
part 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,
Leptonar-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
the 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
designated 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
with 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
expects 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
exploration 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-
week 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 Client 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
astronomers. 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
band dump transmissions, which contain high resolution imagery from the telescope on board the satellite.

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
