International Space Station Astronauts Continue Important Research, Exemplify International Cooperation
Expedition 71 crew continues to unload ~2600 kg of food, fuel, supplies and a new Orlan-MKS spacesuit that arrived via the Progress 91P cargo craft. Roscosmos Cosmonauts Aleksandr Gorbunov, Aleksey Ovchinin and Ivan Vagner are working to improve communications between the ISS and mission controllers around the world. Expected Crew-10 launch, currently set for March 12, should be headed to the International Space Station (ISS) with Commander Anne McClain (born 1979) and Pilot Nichole Ayers (b. 1989), both NASA Astronauts, Roscosmos Cosmonaut Kirill Peskov (b. 1990), and JAXA Astronaut Takuya Onishi (b. 1975). They will join 7 already in LEO for a few days before Gorbunov, Nick Hague (commander), Sunita Williams and Barry (Butch) Wilmore return to Earth in the Dragon spacecraft, completing its 4th ISS roundtrip. The few days’ overlap, although crowded, allows orientation and transfer of maintenance work and ongoing scientific experiments such as crop growth, biofilm reduction, and changes in gene expression due to microgravity. The 7 crew remaining in space will be designated Expedition 73 beginning in mid-April and will include Astronaut Donald Pettit, Ovchinin and Vagner. Ongoing space research involves monitoring muscles and other body systems as astronauts exercise, and analyzing the reaction to space conditions of single-celled organisms. Just-published science news from ISS studies describes the lack of microbial diversity as explanation for astronaut skin rashes, inflammation and immune dysfunction. Perhaps send sauerkraut, poi and yogurt! (Pictured L-R top: McClain, Ayers; L-R bottom: Peskov, Onishi. Image credits: SpaceX, NASA, Roscosmos, JAXA) |

China Gaining Toward Crewed Moon Missions with Long March and Wenchang Developments
Wenchang, Hainan, China is starting to resemble the bustling Cape Canaveral area with increased launches from its original and the new commercial pad at Wenchang Spacecraft Launch Center, and numerous tourist sites for launch viewing and various space-related centers. The next Long March 8 could fly as early as March 11 from the commercial pad at LC-1. In the future, the Tianlong-3 rocket, built by NewSpace company Space Pioneer, will launch from LC-2 in Wenchang to SSO. Chang’E-7 lunar lander, with the ILO-C astronomy from the Moon payload, is set to launch from Wenchang in 2026. The LM 10A, China’s new rocket for crew and cargo missions to Tiangong Space Station, is on track to leave from Wenchang in 2026. The next variant, the 3-core, 92-meter-tall LM 10, will fly Taikonauts around the Moon ~2028, and to the lunar surface-perhaps close to when Artemis lands first women and next men. The Tianwen program, which began with Mars mission Tianwen-1 launched from Wenchang on LM-5, is aiming for Solar System complete exploration. Tianwen-2 launching in May is an asteroid sample return mission. Tianwen-3 in 2028 will be a Mars sample return mission. Tianwen-4 in 2033 is to study Jupiter and send a probe to fly by Uranus followed by Kuiper Belt exploration. The Wenchang International Aerospace City, which was highlighted during the ILOA Galaxy Forum in December 2024, is planned to have a new center for satellite manufacturing starting in June 2025.
