The Expedition 67 crew was back to normal on Friday following the departure of four commercial crew astronauts early Thursday morning. The seven International Space Station astronauts and cosmonauts will live and work in space together until late summer.

The SpaceX Crew-3 mission ended at 12:43 a.m. EDT on Friday when the Dragon Endurance crew ship splashed down off the coast of Tampa, Florida. Nearly 24 hours earlier, Crew-3 Commander Raja Chari with Pilot Tom Marshburn and Mission Specialists Kayla Barron and Matthias Maurer undocked from the Harmony module’s forward port inside Dragon.

After saying farewell to the Crew-3 astronauts early Thursday, the orbiting lab’s four newest astronauts, who arrived the week before aboard the Dragon Freedom spaceship, closed the station’s hatches, went to bed about two hours later, and took the rest of the day off.

On Friday, NASA Flight Engineer Kjell Lindgren, who is one week into his second spaceflight, stowed emergency gear and checked out hydroponic hardware for the XROOTS space botany study. ESA (European Space Agency) Flight Engineer Samantha Cristoforetti, who is also on her second mission, spent her day maintaining orbital plumbing systems.

First time space-flyers Bob Hines and Jessica Watkins partnered once again in the Columbus laboratory module studying how the central nervous system adapts to weightlessness. Hines and Watkins were both selected as members of the 2017 class of astronaut candidates in August of the same year.

The station’s new commander, Oleg Artemyev, started his day installing video gear before continuing his weeklong research on ways to maximize the effectiveness of a space workout. Roscosmos Flight Engineer Sergey Korsakov also participated on the space exercise study before working on networking equipment. Roscosmos Flight Engineer Denis Matveev checked out systems inside the Rassvet and Zarya modules before performing Russian orbital maintenance tasks.

NASA astronaut Tom Marshburn handed over command of the International Space Station to Russian cosmonaut Oleg Artemyev in a traditional Change of Command ceremony which began at 2:35 p.m. EDT today. Artemyev, a veteran of three spaceflights to the space station, will lead the Expedition 67 crew until the end of summer.

Marshburn and his Crew-3 crewmates Kayla Barron, Raja Chari, and ESA astronaut Matthias Maurer have been living aboard the orbital lab since November 11, 2021, and are set to depart tonight. Hatch closure is set for 11:20 p.m. EDT, with undocking following at 1:05 a.m. EDT. The commercial crew quartet is due to splashdown off the coast of Florida  at 12:43 a.m. EDT on Friday, May 6. Watch live on NASA TV, the agency’s website, and the app.

The Crew-3 astronauts worked on final Dragon cargo operations and configuring Dragon for departure, final egress, and hatch closure, as well as transferring emergency hardware from Dragon to the space station prior to departure. The Endurance crew closed out research operations which included transferring and packing frozen samples and ice bricks from the Minus Eighty (Degrees Celsius) Laboratory Freezer for ISS (MELFI) into coldbags in preparation for the return to Earth. MELFI provides the space station storage and fast-freezing of life science and biological samples. The Crew-3 astronauts also removed and stowed their Actiwatches, small, lightweight, wrist-worn devices that simultaneously detect body movement and light intensity. They are used to evaluate sleep-wake adaptation and circadian cycle and determine if space travel has an impact on the sleep-wake patterns of crewmembers.

The station’s four newest astronauts, Kjell Lindgren, Bob Hines, Jessica Watkins, and Samantha Cristoforetti, had a light duty day performing some life science, lab maintenance, and inventory tasks. The foursome and their three Russian crewmates are due to have an off-duty day following the departure of the SpaceX Crew-3 mission.

In the station’s Russian segment, Artemyev and Flight Engineers Sergey Korsakov and Denis Matveev performed monthly maintenance checks on laptops and video equipment, as well as physical training, and a robotic piloting experiment.

NASA and SpaceX managers continue to plan for the departure of four commercial crew astronauts aboard the International Space Station this week. A change of command is also on tap as the 11 orbital residents transition to a seven-member crew before the end of the week.

NASA astronauts Tom Marshburn, Raja Chari, and Kayla Barron, with ESA (European Space Agency) astronaut Matthias Maurer are nearing the end of their space research mission that began in November. The quartet will first see Marshburn hand over station command to Roscosmos Flight Engineer Oleg Artemyev who will lead Expedition 67 until late summer. The following day, the four astronauts will enter the SpaceX Dragon Endurance, undock from the Harmony module’s forward port, then splashdown off the coast of Florida about 24 hours later.

The four departing astronauts have been handing over their responsibilities to the station’s newest quartet that arrived on April 27 aboard the Dragon Freedom. NASA astronauts Kjell Lindgren, Bob Hines, and Jessica Watkins with Samantha Cristoforetti from ESA are in the first week of a four-and-a-half-month research mission on the orbiting lab.

Flight Engineers Hines and Watkins partnered once again inside the Columbus laboratory module exploring how microgravity affects their dexterous manipulation. Lindgren worked on cargo operations inside the Cygnus space freighter then took a robotics test that measures behavioral conditions during spaceflight. Cristoforetti worked on exercise machine components and spent time on station familiarization activities.

Over in the Russian segment of the station, Artemyev took turns with Flight Engineer Sergey Korsakov working out for a study exploring ways to maximize the effectiveness of exercise in weightlessness. Flight Engineer Denis Matveev worked on resupply activities inside the ISS Progress 80 cargo craft before cleaning ventilation systems.

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.
