NASA astronaut Chris Williams, accompanied by Roscosmos cosmonauts Sergey Kud-Sverchkov and Sergei Mikaev, safely arrived at the International Space Station on Thursday, expanding the orbiting laboratory’s crew to 10 for the next two weeks.
The trio launched aboard the Soyuz MS-28 spacecraft at 4:27 a.m. EST (2:27 p.m. Baikonur time) from the Baikonur Cosmodrome in Kazakhstan. After a three-hour, two-orbit journey, the spacecraft docked at 7:34 a.m. to the space station’s Rassvet module.
Following hatch opening, expected about 10:10 a.m., the new arrivals will be welcomed by the Expedition 73 crew, including NASA astronauts Mike Fincke, Zena Cardman, and Jonny Kim; JAXA (Japan Aerospace Exploration Agency) astronaut Kimiya Yui; and Roscosmos cosmonauts Sergey Ryzhikov, Alexey Zubritsky, and Oleg Platonov.
NASA’s live coverage of hatch opening begins at 9:50 a.m. on NASA+, Amazon Prime, and YouTube. Learn how to watch NASA content through a variety of platforms, including social media.
During his stay aboard the space station, Williams will conduct scientific research and technology demonstrations aimed at advancing human space exploration and benefiting life on Earth. He will help install and test a new modular workout system for long-duration missions, support experiments to improve cryogenic fuel efficiency and grow semiconductor crystals in space, as well as assist NASA in designing new re-entry safety protocols to protect crews during future missions.
Expedition 74 is scheduled to begin on Monday, Dec. 8, following the departure of Kim, Ryzhikov, and Zubritsky, as they conclude an eight-month science mission aboard the orbital outpost.
Watch the change of command ceremony at 10:25 a.m. on Sunday, Dec. 7, as station leadership transfers from Ryzhikov to Fincke, live on NASA+.
