+ AO-73 was switched back to full-time transponder mode on February 3rd, 2025. The U/V linear transponder is now operating 24/7 after a month-long period of telemetry collection on the satellite窶冱 electrical power system. While some signs of reduced battery capacity are present, the two Lithium-Ion cells continue to perform well, supporting full transponder operation throughout the orbit. AO-73 features an inverting SSB/CW transponder with an uplink passband from 435.150 to 435.130 MHz (LSB) and a downlink passband from 145.950 to 145.970 MHz (USB). With the transponder active, the satellite also transmits BPSK telemetry on 145.935 MHz at 40mW. The collected telemetry data helps assess the long-term health of the 11-year-old satellite.

+ NASA has confirmed the crew for Axiom Mission 4, set to launch no earlier than spring 2025 aboard a SpaceX Dragon spacecraft from Kennedy Space Center. The mission will be commanded by former NASA astronaut Peggy Whitson, with ISRO astronaut Shubhanshu Shukla as pilot and ESA窶冱 SﾅＢwosz Uznaﾅгki-Wiﾅ嬾iewski and Hungary窶冱 Tibor Kapu as mission specialists. Once docked at the International Space Station, the crew will spend up to 14 days conducting science, outreach, and commercial activities. This mission includes the first ISRO astronaut aboard the station and the first astronauts from Poland and Hungary to stay there. NASA sees private astronaut missions as a way to expand access to space and support commercial activity in low Earth orbit. As the agency shifts focus to deep space exploration through Artemis missions, partnerships with private companies help maintain a human presence in space and support research in microgravity.

+ Indian Space Research Organization's (ISRO) NVS-02 navigation satellite, launched on January 28th aboard a Geostationary Satellite Launch Vehicle (GSLV) Mark 2 rocket, was intended to replace the IRNSS-1E satellite in geostationary orbit as part of India窶冱 NavIC navigation system. However, ISRO confirmed on February 2nd that the satellite窶冱 onboard propulsion system failed due to oxidizer valves not opening, preventing it from reaching its intended orbit. As a result, NVS-02 remains stuck in an elliptical transfer orbit with a perigee of 165 kilometers (103 miles) and an apogee of 37,582 kilometers (23,354 miles), making it vulnerable to reentry due to atmospheric drag. While the spacecraft窶冱 solar panels and other systems are functioning normally, ISRO is exploring alternative mission strategies to utilize it in its current orbit. The 2,250-kilogram (4,960-pound) satellite was the second of five planned NavIC satellites aimed at enhancing regional navigation services. Its failure raises concerns about the future deployment of the NavIC system, and it remains unclear if any backup propulsion systems could adjust its orbit to prevent early reentry.

+ AstroForge, a U.S.-based asteroid mining company, has identified asteroid 2022 OB5 as the target for its upcoming Mission 2, Odin, set to launch in February 2025 aboard a SpaceX Falcon 9 rocket. Odin will serve as a scouting spacecraft, flying as a secondary payload alongside Intuitive Machines' IM-2 lunar lander, and will separate after the rocket窶冱 upper stage fires for the moon. The spacecraft is expected to take about 300 days to reach the asteroid, where it will conduct a flyby to gather crucial imagery and assess the rock窶冱 mining potential. This mission paves the way for AstroForge窶冱 next endeavor, Vestri, which aims to land on the asteroid and initiate resource extraction, potentially launching in late 2025 as part of another rideshare mission. AstroForge, founded in January 2022, seeks to develop sustainable methods for mining precious metals from asteroids, although its first mission, Brokkr-1, launched in April 2023, failed to activate its onboard refinery technology. The company has also secured a contract with Stoke Space for future launches aboard the Nova rocket to support its ambitious mining goals.
