NASA astronaut Anne McClain, David Saint-Jacques of the Canadian Space Agency, and Oleg Konenenko of the Russian space agency Roscosmos joined Expedition 57 Commander Alexander Gerst of ESA (European Space Agency), Serena Auñón-Chancellor of NASA, and Sergey Prokopyev of Roscosmos aboard the International Space Station when the hatches between the Soyuz spacecraft and the orbiting laboratory officially opened at 2:37 p.m. EST.
The arrival briefly restores the station’s crew complement to six until Auñón-Chancellor, Gerst and Prokopyev return to Earth Dec. 20. Expedition 58 officially begins once the three departing spacefarers undock from the space station.
McClain, Saint-Jacques and Konenenko will spend more than six months conducting hundreds of science investigations in fields such as biology, Earth science, human research, physical sciences and technology development, providing the foundation for continuing human spaceflight beyond low-Earth orbit to the Moon and Mars. Some of the investigations they will conduct are sponsored by the U.S. National Laboratory on the space station, which Congress designated in 2005 to maximize its use for improving quality of life on Earth. Highlights of upcoming investigations include experiments in forest observation, robotic refueling, and satellite deployment.
The crew is scheduled to be onboard during the first test flights of NASA’s Commercial Crew Program, which will return human spaceflight launches to U.S. soil.
In March, the station will again return to a full complement of six crew members when they are joined for Expedition 59 by NASA astronauts Nick Hague and Christina Koch and Alexey Ovchinin of Roscosmos.
This is the first spaceflight for both McClain and Saint-Jacques and the fourth trip to the space station for Kononenko.
