NASA astronaut Tom marshburn handed over the command of the international space station to Russian astronaut Oleg artemiyev at the traditional command transfer ceremony that began at 2:35 p.m. EST on May 4 Artemiyev has participated in three international space station missions and will lead the crew of expedition 67 until the end of summer.
Marshburn and his crew members Kayla Barron, Raja Chari and ESA astronaut Matthias Maurer have been living in the orbital laboratory since November 11, 2021 and will leave on the evening of November 4. The door will be closed at 11:20 p.m. Eastern time, and then the SpaceX spacecraft will leave at 1:05 a.m. Eastern time on the 5th. The commercial crew of four will then splash down off the coast of Florida. People can watch the live broadcast on NASA TV, the agency's website and applications.
Crew-3 astronauts are engaged in the final cargo operation of the Dragon spacecraft, configure the departure, final evacuation and door closure of the Dragon spacecraft, and transfer emergency hardware from the Dragon spacecraft to the space station before departure. The endurance crew completed their research work, including transferring and packaging frozen samples and ice bricks of minus eight (degrees Celsius) laboratory freezer for ISS (Melfi) into cold bags for return to earth. Melfi provides the space station with the storage and rapid freezing of life sciences and biological samples. Crew-3 astronauts also took out and put away their actiwatches, a small, lightweight, wrist worn device that can detect body movement and light intensity at the same time. They were used to assess sleep wake adaptation and circadian rhythm cycles and to determine whether space travel had an impact on crew sleep wake patterns.
The station's four newest astronauts, Kjell Lindgren, Bob Hines, Jessica Watkins and Samantha cristoforetti, performed some life sciences, laboratory maintenance and inventory tasks during the day. The four and three Russian astronauts will have a rest day after the SpaceX crew-3 mission leaves.
In the Russian segment of the space station, artemiyev and flight engineers Sergey Korsakov and Denis Matveev carried out monthly maintenance and inspection of notebook computers and video equipment, as well as physical training and robot driving experiments.
