Europe’s ExoMars Trace Gas Orbiter and Schiaparelli lander arrived at Mars Wednesday, with the orbiter safely captured by Martian gravity after a critical engine firing. The lander’s fate is unknown after mission control lost contact just before touchdown.

The three U.S. astronauts aboard the International Space Station said Monday they’re ready to sign up for a trip to the moon if NASA can meet the Trump administration’s newly stated goal of returning Americans to the lunar surface within the next five years.

SpaceX took a group of reporters and photographers just offshore the Falcon 9 rocket’s landing point Tuesday, a day after the 15-story booster made a pinpoint touchdown after helping send 11 communications satellites into orbit.
