CAPE CANAVERAL, Fla. (AP) — Four astronauts are back on Earth after a space station mission that lasted almost eight months. A SpaceX capsule carrying the crew parachuted into the Gulf of Mexico off the Florida coast before dawn Friday. The three Americans and one Russian should have returned from the International Space Station two months ago, but were delayed by Boeing’s Starliner crew capsule and weather. Shortly after splashdown, NASA said one of its astronauts had a medical issue. The space agency says the unidentified astronaut is in stable condition and remains at a Florida hospital as a “precautionary measure.”
