Four new flight engineers are adapting to life aboard the International Space Station as a quartet of Expedition 70 crew members nears the end of its mission. Meanwhile, the expanded crew still found time for a variety of biology and physics studies while maintaining the upkeep of the orbital outpost.

First time space-flyers Matthew Dominick, Jeanette Epps, and Alexander Grebenkin along with veteran station resident Michael Barratt are in their first full day on the orbital outpost. They will spend a few hours each day for about a week familiarizing themselves with space station systems and getting up to speed with life in weightlessness. The new foursome will be conducting advanced space research and orbital lab maintenance activities for the next six months.

The Expedition 70 crew will soon return to seven residents again as another quartet that has been on the station since Aug. 27, 2023, prepares for its departure. NASA astronaut Jasmin Moghbeli will command Pilot Andreas Mogensen, and Mission Specialists Satoshi Furukawa and Konstantin Borisov back to Earth no earlier than Monday, March 11. The foursome will undock from the Harmony module’s space-facing port inside the SpaceX Dragon “Endurance” spacecraft and parachute to a splashdown off the coast of Florida ending a six-and-a-half-month mission orbiting Earth.

The four homebound crew members on Wednesday checked the pressure suits they will wear inside “Endurance” during the ride back to Earth. At the end of the day, they joined the seven other orbital residents and reviewed everyone’s roles and responsibilities in the unlikely event of an emergency aboard the station.

There was still time for science in space as Dominick set up medical hardware including an ultrasound scanner and blood pressure measurement gear. He then conducted scans on NASA Flight Engineer Loral O’Hara and measured her blood pressure collecting data for the CIPHER suite of 14 human research experiments. CIPHER is documenting an astronaut’s health during a long-term spaceflight.

Furukawa installed science hardware in the Destiny laboratory module for a semiconductor manufacturing study that could support production in space and more efficient technologies on Earth. Epps set up a microscope to observe the growth of cell cultures for an investigation that may promote the creation of artificial organs for transplant patients on Earth. Finally, Grebenkin attached sensors to himself recording his heart activity in microgravity.

In the Roscosmos segment of the station, cosmonauts Oleg Kononenko and Nikolai Chub continued installing cargo containers inside the Zarya module. The duo earlier checked out carbon dioxide monitors and cleaned fan screens inside the Progress 86 cargo craft.

11 crew members now reside aboard the International Space Station following the arrival of the SpaceX Crew-8 mission early Tuesday morning. The four new Crew-8 members will spend the next few days getting used to life on orbit as four Expedition 70 crewmates pack up for their return to Earth.

The SpaceX Dragon “Endeavour“ spacecraft docked to the forward port of orbital outpost’s Harmony module at 2:28 a.m. EST on Tuesday. About an hour-and-a-half later, Crew-8 Commander Matthew Dominick, Pilot Mike Barratt, and Mission Specialists Jeanette Epps and Alexander Grebenkin opened Dragon’s hatch and entered Harmony officially becoming station flight engineers. Soon after, the new quartet, with the Expedition 70 septet, called down to Earth for welcome remarks.

Afterward, the entire crew quickly got to work first conducting a safety briefing, then unpacking new science and supplies, conducting health checks, and more. The crewmates transferred Dragon freezers containing research samples and installed them into science racks throughout the station. Tuesday’s health studies included testing the inner-ear balance system, conducting eye scans with an ultrasound device, and evaluating a specialized suit’s ability to help a crew member readjust to Earth’s gravity.

The foursome will live aboard the space station for a six-month space research mission. They will take advantage of the microgravity environment to explore the mechanisms behind neurodegenerative disorders, how spaceflight affects plant growth to sustain crews, countering space-caused fluid shifts that create head and eye pressure in astronauts, and the potential for algae to improve spacecraft life support systems.

While Crew-8 gets up to speed with space station systems, four Expedition 70 crewmates are nearing their departure after a six-and-a-half-month mission on orbit. NASA astronaut Jasmin Moghbeli will lead Andreas Mogensen of ESA (European Space Agency), Satoshi Furukawa of JAXA (Japan Aerospace Exploration Agency) and Konstantin Borisov of Roscosmos back to Earth inside the SpaceX Dragon “Endurance” spacecraft. The homebound quartet has been aboard the station since Aug. 27, 2023, and is expected to undock from Harmony’s space-facing port no earlier than Monday, March 11.

The station’s other three crewmates, NASA astronaut Loral O’Hara and cosmonauts Oleg Kononenko and Nikolai Chub, have been aboard the station since Sept. 15, when they docked to the Rassvet module inside the Soyuz MS-24 crew ship. O’Hara is due to return to Earth in April while Kononenko and Chub will stay in space for a few more months.
