The four-member crew — three astronauts and a cosmonaut — launched in March and conducted more than 200 experiments. They also performed spacewalks and did maintenance on the orbiting outpost.

The four members of the Crew-7 mission are set to dock to the International Space Station on Sunday. They'll spend six months on the orbiting outpost conducting science and other experiments.

A new study of astronaut blood finds that space travel reduces the expression of 100 genes related to the immune system.

More than 7,000 pounds of supplies are heading to the station, including science experiments and a new set of solar arrays to boost station's power capacity.

The return caps a nine-day mission to the International Space Station. The mission was funded by Axiom Space, a company that wants to build and operate the world's first commercial space station.

The mandatory isolation aims to protect the current station crew from any Earth-based pathogens that could hitch a ride with the four private astronauts.

The U.S.-Russian-Japanese crew returned to Earth late Saturday after spending five months at the International Space Station, arriving last October. Their capsule splashed down in the Gulf of Mexico just off the Florida coast.

SpaceX launched four astronauts to the International Space Station for NASA on Thursday, including the first person from the Arab world going up for an extended monthslong stay.

SpaceX will try once again to launch a crew of four to the International Space Station just after midnight Thursday from Kennedy Space Center. An attempt Monday was scrubbed in the final minutes of the countdown.

Mission managers called off the launch with around five minutes remaining in the countdown. The crew will have another chance Thursday to launch to the International Space Station.
