International Space Station (ISS) Expedition 54 began December 14, 2017 with the handover of command by Expedition 53 commander Randy Bresnik (NASA) to Expedition 54 commander, Alexander Misurkin (RSA). Shortly afterward, Expedition 53 crewmembers Bresnik, Paolo Nespoli (ESA), and Sergey Ryazanskiy (RSA) departed the station on their Soyuz MS-05 spacecraft, returning to Earth December 14, 2017.
Days later, Misurkin, and remaining flight engineers Joseph Acaba (NASA) and Mark Vande Hei (NASA) welcomed the three new Expedition 54 crewmembers to the station. Scott Tingle (NASA), Anton Shkaplerov (RSA) and Norishige Kanai (JAXA) launched December 17 on the Soyuz MS-07 spacecraft.
While on orbit, the Expedition 54 crew was host to four cargo supply missions, completed several spacewalks outside the ISS to install new science research, and performed hundreds of experiments inside the station’s laboratories. In addition, Acaba and Vande Hei participated in multiple educational events as part of the Year of Education effort.
Expedition 54 concluded with the return to Earth of Misurkin, Acaba, and Vande Hei on February 27, 2018.
