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,[3][4][5] with Danish astronaut Andreas Mogensen taking over the ISS command from Expedition 69 cosmonaut Sergey Prokopyev. It will end on with the departure of NASA astronaut, Loral O'Hara on Soyuz MS-24 in March 2024.[6]

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.[7]
The crew will later be replenished by subsequent missions in the expedition alongside non-expedition crews.[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.[8][9]
