After multiple helium leaks and thruster problems, on June 6, 2024 at 17:33 UTC, the US Boeing CST-100 Starliner “Calypso” (Boe-CFT mission) spacecraft docked with the forward docking port of the “Harmony” module of the International Space Station. The spacecraft delivered US astronauts Barry Wilmore and Sunita Williams to the ISS. The new comers joined current ISS Expedition 71 members – Oleg Kononenko, Nikolai Chub, Tracy Caldwell-Dyson, Matthew Dominick, Michael Barratt, Jeanette Epps and Alexander Grebenkin.
