ISS Undergoes Multi-Crew Changeovers and Cargo Arrival Heading into Expedition 71

The International Space Station, now more than 25 years in LEO and having 270+ Astronaut visitors, will see many rendezvous and departures this month of crewed and cargo spacecraft. Expedition 70 Commander Oleg Kononenko, Nikolai Chub and Loral O’Hara (arrived in Soyuz MS-24), and SpaceX Crew-8 members Matthew Dominick, Michael Barratt, Jeanette Epps and Alexander Grebenkin are set to welcome Oleg Novitsky, Tracy Caldwell-Dyson and the first Belarus woman in space Marina Vasilevskaya via Soyuz MS-25 on March 21. Exp 70 will remain a 10-member crew until April 2 when O’Hara, and “Visiting Expedition 21 Crew” Novitsky and Vasilevskaya are planned to return to Earth in Soyuz-24 and Expedition 71 will officially begin. Kononenko and Chub are assigned for a one-year long mission that will end on September 24 (marking 375 continuous days). Cargo craft docked are NG Cygnus-20 (S.S. Patricia “Patty” Hilliard Robertson), Progress 86 and 87 resupply ships. Set to launch March 23 aboard a SpaceX Falcon 9 rocket is the CRS-30 ship with nearly 3,000 kg of cargo including experiments C4 Photosynthesis in Space (APEX-09) which will grow 2 different grasses to test their ability to capture carbon dioxide in microgravity, the Nano Particle Haloing Suspension investigation to test how particles interact within an electrical field, and a Multi-resolution Scanner to be added to Astrobee to further test automated 3D sensing, mapping, and situational awareness systems.

JAXA SLIM and Intuitive Machines Odysseus Await Lunar Daylight for Possible Reactivation

2 Moon Landers, JAXA SLIM and Intuitive Machines Odysseus, are in hibernation on the lunar surface following semi-successful landings and periods of operation. The US$121.5M SLIM is resting 55 m east of targeted site within Cyrillus crater (near Shioli crater) on Mare Nectaris (13.3160°S, 25.2510°E) following Jan 19 landing which, while meeting the primary objective of soft landing within a 100m ellipse, settled in an off-nominal orientation due to a failed engine nozzle. Operations were suspended after a brief time in which multiband spectroscopic camera (MBC) collected data and LEV-1 / LEV-2 mini rovers were deployed due to battery depletion, but resumed Jan 29 after the Sun moved sufficiently westward to power the craft’s photovoltaic panel. Activity was again suspended March 1 upon lunar nightfall, but may resume sometime during the upcoming lunar day. ~2,050 km to the southwest, near Malapert A crater (80.13°S, 1.44°E), the $118M Nova-C class Odysseus lander is also awaiting daybreak for what mission planners hope will be a second period of operation following a similarly off-nominal landing caused by an oversight which prevented operation of the craft’s laser rangefinder, affecting orientation after tip-over 1.5 km from targeted landing site. Lunar day begins around March 16 for SLIM, whereas the Sun rises later near the Moon South Pole location of Odysseus, around March 17. Controllers are likely to wait to issue activation commands until the angle of sunlight is optimal for their respective landers. (Image Credits: JAXA, IM)
