Live coverage: International Space Station crew lands in Kazakhstan

After years of studies, test-firings and a survey of U.S. industry in preparation for launch of a Mars Sample Return mission in 2026, NASA has settled on a solid-fueled design for a miniature rocket with a first-of-its-kind purpose: Launching a payload from Mars for a trip back to Earth.

A three-man crew closed out a 196-day expedition in orbit late Wednesday with a parachute-assisted landing on the steppe of Kazakhstan aboard the Russian Soyuz MS-17 spacecraft. NASA astronaut Chris Cassidy, Soyuz commander Anatoly Ivanishin, and flight engineer Ivan Vagner undocked from the International Space Station at 7:32 p.m. EDT (2332 GMT) Wednesday, and the trio landed at 10:54 p.m. EDT (0254 GMT).
