Expedition 57 Mission Patch


Expedition 56 commander Andrew Feustal (NASA) turned command of the International Space Station (ISS) over to Alexander Gerst (ESA) on October 4, 2018, marking the end of Expedition 56 and the beginning of Expedition 57. Feustal, and his Expedition 56 crewmates, Oleg Artemyev (RSA) and Richard Arnold (NASA) then departed the ISS in their Soyuz spacecraft, landing in Kazakhstan about three hours later.

Gerst remained aboard the International Space Station (ISS) with crewmates Serena Auñón-Chancellor (NASA), and Sergey Prokopyev (RSA) to await the arrival of the remaining Expedition 57 crew a week later.

Alexey Ovchinin (RSA) and Nick Hague (NASA) launched on October 11, 2018. However, their Soyuz developed an anomaly during ascent and the launch aborted. Ovchinin and Hague were safely returned to Earth.

With the size of the Expedition 57 crew reduced, the remaining crew continued to maintain the ISS while performing many research experiments that will pave the way for future long-duration exploration missions.

After the investigation of the launch anomaly was completed, launches resumed in December. The Expedition 58 crew, including Oleg Kononenko (RSA), Anne McClain (NASA), and David Saint-Jacques (CSA), launched to the ISS on December 3, 2018 and joined the Expedition 57 crew briefly. Two and a half weeks later, Gerst turned command over to Kononenko and prepared to return to Earth with crewmates Auñón-Chancellor and Prokopyev.

Expedition 57 ended on December 20, 2018.
