Expedition 57/58: Change of Command Ceremony

Expedition 58 was the 58th expedition to the International Space Station, which began on December 20, 2018 with the departure of the Expedition 57 crew.^[2]^[3] It was commanded by cosmonaut Oleg Kononenko, with astronauts Anne McClain and David Saint-Jacques as flight engineers; the trio launched on board Soyuz MS-11 on December 3, 2018, marking the 100th orbital launch of the year.^[4]

Kononenko, McClain and Saint-Jacques subsequently transferred to Expedition 59 on March 15 2019, when Aleksey Ovchinin, Nick Hague and Christina Koch arrived on board Soyuz MS-12.^[5]^[1]

History

During early planning, the expedition was scheduled to include rookie cosmonaut Nikolai Tikhonov. However, Tikhonov's assignment was postponed (for the second time) due to delays in launching the Russian Nauka module.^[6]^[7] Tikhonov has been reassigned to the Soyuz MS-14 flight scheduled for late 2019.

As of October 2018, plans called for the expedition to feature a crew of five: cosmonaut Aleksey Ovchinin and astronaut Nick Hague would have joined the Expedition 57 crew in October 2018, and subsequently transferred to Expedition 58; they would have been joined by Kononenko, McClain and Saint-Jacques in December 2018. Ovchinin and Hague would then have returned to Earth in April 2019. Subsequently, the Expedition 59 mission would have begun with Kononenko as commander. However, the Soyuz MS-10 spacecraft carrying Ocvhinin and Hague aborted during its launch on October 11, 2018; the two crew returned safely to Earth.^[8]

Following the Soyuz MS-10 abort, NASA Administrator Jim Bridenstine announced on October 23, 2018 that Soyuz flights to the ISS were expected to resume in December 2018.^[9] At first, it was assumed that Expedition 58 would initially consist of three crew members who would then be joined later by the crew of Soyuz MS-12, bringing the crew up to six. However, in the post-launch news conference for Soyuz MS-11, NASA announced that the Soyuz MS-12 crew would become the station Expedition 59/60 crew. Expedition 58 was therefore a three person increment.
