Expedition 70 crew portrait 

Expedition 70 is the 70th long-duration expedition to the International Space Station. The expedition began with the departure of Soyuz MS-23 on 27 September 2023[2][3][4] with Danish astronaut Andreas Mogensen taking over the ISS command from Expedition 69 cosmonaut Sergey Prokopyev. It will end with the departure of NASA astronaut Loral O'Hara on Soyuz MS-24 on 6 April 2024.[5]

Background, Crew and Events

Initially, the expedition consisted of Andreas and his three SpaceX Crew-7 crewmates, Jasmin Moghbeli, Satoshi Furukawa and Konstantin Borisov from America, Japan, and Russia respectively, as well as Russian cosmonauts Oleg Kononenko and Nikolai Chub (both on a year long ISS mission) and another American astronaut Loral O'Hara, who launched aboard Soyuz MS-24 on September 15, 2023 and were transferred from Expedition 69 alongside the SpaceX Crew-7 astronauts.[6]

However, even after several months of outfitting EVAs and RTOd heat radiator installation, six months later on 9 October 2023, the Nauka RTOd radiator malfunctioned before active use of Nauka (the purpose of RTOd installation is to radiate heat from Nauka experiments). The malfunction, a leak, rendered the RTOd radiator unusable for Nauka. This is the third ISS radiator leak after Soyuz MS-22 and Progress MS-21 radiator leaks. If a spare RTOd is not available, Nauka experiments will have to rely on Nauka's main launch radiator and the module could never be utilized to its full capacity.[7][8]

Later, the crew was replenished by subsequent missions in both expedition and visiting crews, i.e., Axiom Mission 3, (consisting of American Michael López-Alegría, Italian astronaut Walter Villadei, ESA Swedish Project astronaut Marcus Wandt, and Turkish astronaut Alper Gezeravcı), SpaceX Crew-8, (consisting of American Matthew Dominick, Michael Barratt, Jeanette Epps and Russian Alexander Grebenkin) and Soyuz MS-25, (consisting of Russian Oleg Novitsky, Belarusian Marina Vasilevskaya, and American Tracy Caldwell-Dyson).[5] 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 May during Expedition 71.[9]

Besides the expedition crew, Crew Dragon visited 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 carried expedition member Tracy Caldwell-Dyson and visitors Oleg Novitsky of Roscosmos and Marina Vasilevskaya, a flight attendant trained by the Belarus Space Agency for ISS EP-21. One week after docking, Novitsky and Vasilevskaya will return with expedition member Loral O'Hara on the Soyuz MS-24 vehicle. Meanwhile, Kononenko and Chub, who launched on MS-24, will return on the MS-25 vehicle.[5]
