Four astronauts who have been aboard the International Space Station since November continue to prepare for their return to Earth. This comes at the same time as four new astronauts are beginning their mission and getting used to living and working aboard the orbiting lab.

Expedition 67 Commander Tom Marshburn is getting ready to hand over station control to Roscosmos Flight Engineer Oleg Artemyev. The traditional change of command ceremony will take place Tuesday at 2:45 p.m. EDT live on NASA TV’s app and website, when the station’s nine flight engineers witness Marshburn handing over the station’s leadership role to Artemyev.

In the meantime, Marshburn and Flight Engineers Raja Chari, Kayla Barron, and Matthias Maurer, are packing up and preparing for their return to Earth. The quartet will board the SpaceX Dragon Endurance later this week then undock from the Harmony module’s forward port ending their stay on the space station. Chari will command the ride back home when the foursome parachutes to a splashdown off the coast of Florida about a day after undocking.

Meanwhile, the station’s four newest crew members, who have been on the station less than a week, are kicking off their first science experiments while also getting up to speed with lab systems and operations.

NASA’s first time space-flyers Robert Hines and Jessica Watkins worked in the Columbus laboratory module on Monday and explored how microgravity affects their dexterous manipulation. NASA Flight Engineer Kjell Lindgren, on his second mission, collected and stored his blood and urine samples then spent the rest of the day on station familiarization and handover activities. ESA (European Space Agency) Flight Engineer Samantha Cristoforetti serviced life support equipment while also spending time adapting to life on the space station.

Artemyev, on his third space station mission, is about to take command of the Expedition 67 crew until late summer. Today, he worked on a pair of Russian experiments exploring future spacecraft and robotic piloting techniques, as well as effective ways to exercise in weightlessness. Flight Engineer Denis Matveev inspected the ISS Progress 80 cargo craft then continued cleaning up after April 28’s spacewalk to activate the European robotic arm. Flight Engineer Sergey Korsakov swapped out a Russian computer before participating in more space exercise research at the end of the day.

Two Roscosmos cosmonauts went on a spacewalk to activate the new European robotic arm (ERA) less than a day after the SpaceX Crew-4 mission arrived at the International Space Station. The next mission event taking place will occur next week when four Expedition 67 astronauts complete their stay aboard the orbiting lab.

Cosmonauts Oleg Artemyev and Denis Matveev exited the station in their Orlan spacesuits at 10:58 a.m. EDT on Thursday beginning the fifth spacewalk of the year. Fellow cosmonaut Sergey Korsakov assisted the spacewalkers from inside the station’s Russian segment as they released the ERA from its launch restraints on the Nauka multipurpose laboratory module and monitored the new robotic arm’s first motion.

The day before, the SpaceX Dragon Freedom crew ship, carrying four Crew-4 astronauts, docked to the Harmony module’s space-facing port at 7:37 p.m. EDT. Less than two hours later, NASA astronauts Kjell Lindgren, Robert Hines, and Jessica Watkins with ESA (European Space Agency) astronaut Samantha Cristoforetti, entered the station beginning a four-and-a-half month research mission aboard the space station. The 11-person crew will live and work together until next week when the SpaceX Crew-3 mission ends.

Station Commander Tom Marshburn along with Flight Engineers Raja Chari, and Kayla Barron, all NASA astronauts, and ESA astronaut Matthias Maurer, are packing up to end their stay on the orbiting lab. The four astronauts representing the Commercial Crew Program are finalizing a six-month science mission on the space lab. NASA and SpaceX mission managers are planning for the quartet to enter the Dragon Endurance crew ship and undock from Harmony’s forward port for a splashdown off the coast of Florida next week.
