NASA’s two stuck astronauts took their first spacewalk together Thursday, exiting the International Space Station almost eight months after moving in. Commander Suni Williams and Butch Wilmore removed a broken antenna and wiped the station’s exterior for evidence of any microbes that might still be alive after launching from Earth and escaping through vents.

Elon Musk says Donald Trump has asked SpaceX to rescue two astronauts who have been in space for more than seven months — even though NASA has said there's a plan in place.
