CubeSats are only about twice the size of a Rubik's Cube. Once dismissed as tools for students learning the principles of aerospace engineering, they're now being used for more sophisticated missions.
In what NASA is calling "HERstory" in space, Christina Koch and Jessica Meir stepped outside the International Space Station Friday to replace a bad battery charger.
Astronauts Christina Koch and Jessica Meir will replace a faulty power regulator on the International Space Station. Only 15 women have participated in spacewalks, and all were accompanied by men.
The space agency unveils two new spacesuits for a planned 2024 return to the moon. They're designed to be more comfortable and easier to move around in than their Apollo-era forerunners.
Calling it "the most inspiring thing" he's ever seen, SpaceX's CEO talked up his company's big innovation and plans to fast-track production of the spacecraft. He hopes to fly passengers by next year.

Neil Armstrong's Apollo 11 spacesuit is about to go back on public display after a Smithsonian effort to preserve it. The effort wasn't to make it pristine. Lunar dust still covers the boots.
Kranz led the earliest missions to the moon, including Apollo 11 and Apollo 13, and says he wants the room to inspire American students to study science and technology.
These works make apparent how singular an achievement America's moon landing was — and show that half a century later we're still grappling to understand its long-term meaning.
A fictitious asteroid is the focus of a realistic exercise, as experts at the Planetary Defense Conference run through how the Earth would respond to news of a looming asteroid strike.
Researchers are currently looking for candidates who will stay in bed 24 hours a day, seven days a week for 60 straight days for a study on how the body adapts to weightlessness.
