Peggy Whitson, America’s most experienced astronaut with nearly two years in orbit over three missions, returns to Earth Saturday after an extended 288-day stay aboard the International Space Station, landing on the steppe of Kazakhstan with Soyuz MS-04 commander Fyodor Yurchikhin and NASA flight engineer Jack Fischer.

A commercial cargo carrier owned and operated by SpaceX pulled into port at the International Space Station on Monday, three days after launching from Cape Canaveral with a NASA Earth science instrument, a spare hand for the lab’s Canadian robotic arm, and an AI-powered helper bot for the research lab’s six-person crew.

Europe’s Sentinel 5P satellite, fitted with a Dutch-developed spectrometer to measure gases in Earth’s atmosphere, was fueled and mated to its Russian Rockot booster over the last month at the Plesetsk Cosmodrome, a military complex around 500 miles (800 kilometers) north of Moscow.
