Expedition 70 is the 70th long-duration expedition to the International Space Station. It began with the usual-departure of Soyuz MS-23 on 27 September 2023,[2][3][1] with Danish astronaut Andreas Mogensen taking over the ISS command from Expedition 69 cosmonaut Sergey Prokopyev.

4/2/2024: Ending with the departure of Soyuz MS-24, it carries NASA astronaut Loral O'Hara and a visiting non-mission crew.[4]

Background, Crew, and Events

At first--respectivey--the expedition consists of Andreas and his three SpaceX Crew-7 crewmates, Jasmin Moghbeli, Satoshi Furukawa, and Konstantin Borisov from America, Japan and Russia, plus some Russian cosmonauts Oleg Kononenko and Nikolai Chub [5]

9/15/2023: Another American astronaut: Loral O'Hara, launched-aboard Soyuz MS-24, and were transferred from Expedition 69, with the SpaceX Crew-7 astronauts. Until the gracious tradegy...[6]

10/9/23: 6 months later, the Nauka RTOd radiator malfunctioned before active use of Nauka [7]

This is the 3rd ISS radiator-leak after Soyuz MS-22 and Progress MS-21 radiator leaks. If a spare RTOd is unavailable, Nauka experiments must rely on Nauka's main launch radiator; the module could never be full; it'll ALWAYS be empty forever and ever and ever![8][9]

Later, crew was replenished by subsequent-missions in both expedition non-expedition crews alike, Axiom Mission 3 (consisting of American Michael López-Alegría, Italian astronaut Walter Villadei, ESA Swedish Project astronaut Marcus Wandt and Turkish astronaut Alper Gezeravcı).[4] Originally, the Boeing Starliner Crewed Flight Test was supposed-to dock during the expedition. Instead, it was again moved farther down the vehicle schedule to April, where it'll be part of Expedition 71. [10]

Besides the expedition crew, Crew-Dragon'll visit the station, carrying Axiom Mission 3, consisting of Michael López-Alegría of Axiom Space (formerly NASA), Walter Villadei of the Italian Ministry of Defence, Alper Gezeravcı of the Turkish Space Agency, and Marcus Wandt of the Swedish National Space Agency.[16]

The Soyuz MS-25 vehicle will carry expedition member: Tracy Caldwell-Dyson and visitors Oleg Novitsky of Roscosmos and Marina Vasilevskaya, a flight attendant trained by the Belarus Space Agency for Visiting Expedition 21. 1 week after docking, Novitsky and Vasilevskaya will return with expedition member Loral O'Hara on the Soyuz MS-24 vehicle.

September 2024: Meanwhile, Kononenko & Chub--originally launching on MS-24--will return on the MS-25 vehicle.
