CAPE CANAVERAL, Fla. (AP) — Four astronauts from four countries caught a lift back to Earth with SpaceX on Tuesday to end a half-year mission at the International Space Station.

Their capsule streaked across the U.S. in the predawn darkness and splashed into the Gulf of Mexico near the Florida Panhandle.

NASA’s Jasmin Moghbeli, a Marine helicopter pilot, led the returning crew of Denmark’s Andreas Mogensen, Japan’s Satoshi Furukawa and Russia’s Konstantin Borisov.

They moved into the space station last August. Their replacements arrived last week in their own SpaceX capsule.

“We left you some peanut butter and tortillas,” Moghbeli radioed after departing the orbiting complex on Monday. Replied NASA’s Loral O’Hara: “I miss you guys already and thanks for that very generous gift.”

O’Hara has another few weeks at the space station before leaving aboard a Russian Soyuz capsule.
