Astronauts blasted into orbit from the U.S. for the first time in nearly a decade, three countries sent spacecraft hurtling toward Mars, and robotic explorers grabbed rocks from the moon and gravel from an asteroid for return to Earth.

The International Space Station was a cramped, humid, puny three rooms when the first crew moved in. Twenty years and 241 visitors later, the complex has a lookout tower, three toilets, six sleeping compartments and 12 rooms, depending on how you count.

A NASA spacecraft is stuffed with so much asteroid rubble from this week's grab that it's jammed open and precious particles are drifting away in space, scientists said Friday.

After almost two years circling an ancient asteroid hundreds of millions of miles away, a NASA spacecraft this week will attempt to descend to the treacherous, boulder-packed surface and snatch a handful of rubble.

The jig may be up for an "asteroid" that's expected to get nabbed by Earth's gravity and become a mini moon next month.

Two NASA astronauts returned to Earth on Sunday in a dramatic, retro-style splashdown, their capsule parachuting into the Gulf of Mexico to close out an unprecedented test flight by Elon Musk's SpaceX company.

Two U.S. astronauts about to make the first splashdown return in 45 years said Friday they'll have seasick bags ready to use if needed.

Spacewalking astronauts completed their part of a three-year power upgrade to the International Space Station on Thursday, replacing six more outdated batteries with powerful new ones.

NASA's next Mars rover is honoring all the medical workers on the front lines of the coronavirus battle around the world.
