+ Russia successfully launched its 89th Progress cargo spacecraft, Progress MS-28, to the International Space Station (ISS) on August 15, 2024. The uncrewed spacecraft lifted off from the Baikonur Cosmodrome in Kazakhstan aboard a Soyuz rocket at 0320 UTC. Carrying nearly three tons of food, scientific equipment, and other supplies, the spacecraft autonomously docked with the ISS on August 17 at 0553 UTC, connecting to the rear port of the Zvezda service module. This docking occurred just days after the previous cargo spacecraft, Progress MS-26, was deorbited on August 12 following its six-month mission. With its arrival, Progress MS-28 joined two other freighters, including Cygnus NG-21, and three crewed spacecraft already at the ISS. The successful mission continues Russia's long-standing contribution to ISS resupply operations. (ANS thanks Mike Wall, Space.com https://www.space.com/, for the above information)

+ The European Space Agency's Jupiter Icy Moons Explorer (Juice) mission is making headlines with its dual gravity assist maneuver this week. After a successful flyby of the moon on August 19, 2024, Juice passed Earth on August 20, 2024, marking the first-ever lunar-Earth double flyby. This maneuver uses Earth's gravity to adjust Juice's trajectory, setting it up for a flyby of Venus in August 2025 and ultimately aiming for Jupiter's orbit by July 2031. The spacecraft's two cameras are capturing and sending images back to Earth, while mission operators are closely monitoring the high-risk maneuver to ensure precision. With Jupiter being nearly 500 million miles away, this gravity assist strategy allows Juice to conserve fuel and carry a variety of scientific instruments. The mission's success relies on careful navigation and timing, as any deviation could jeopardize its ambitious goals.

+ Space is hard: NASA's BurstCube, which deployed from the ISS in April, is a 6U CubeSat that detects gamma rays from short gamma-ray bursts, likely caused by neutron star collisions. BurstSat, unfortunately, lost one of its magnetorquers during commissioning, along with one solar panel that did not fully deploy. The team has been able to continue the satellite's mission by compensating for the malfunctioning equipment through the use of a Sun-pointing configuration. But due to these failures, the mission will likely reenter sooner than expected, around the end of 2024. [Before complaining about the failure of your favorite HamSat, consider that even NASA has issues!] (ANS thanks The Orbital Index https://orbitalindex.com/ for the above information.)

+ The FCC has granted SpaceX permission to upgrade its first-generation Starlink satellites with second-generation technology, aiming to enhance broadband quality for its users. This upgrade is expected to improve service, especially in polar regions, by using advanced beam-forming and digital processing technologies. SpaceX initially launched first-generation satellites in 2019 and applied in 2023 to integrate the new technology. Despite pushback from Dish Network over potential interference issues, the FCC dismissed these concerns, supporting SpaceX's plans to optimize spectrum use and increase network capacity. SpaceX will replace the older satellites with upgraded ones as they reach the end of their operational period, rather than de-orbiting them rapidly. The overall goal is to provide more robust service to underserved areas across the country. (ANS thanks Michael Kan, PCMag https://www.pcmag.com/, for the above information).
