New estimates using the planet’s surface wrinkles show that our smallest planet is growing even smaller, at a faster clip than expected.

Flaming chunks of metal crash into homes, farms and parking lots. Who’s to blame? And who pays for the damage?

A spacecraft meant to push NASA’s Swift Observatory to a higher orbit malfunctioned and started tumbling several days ago. Engineers think it can still succeed.

It was the 13th test overall of Starship. The success is a boon to NASA’s moon plans and SpaceX’s hopes to deploy a million data centers in orbit.

They’re less dense than cotton candy, and they will help astrophysicists better understand the most unusual ways giant planets can form.

The 33 engines of the rocket’s booster stage had begun to ignite during Thursday’s launch attempt, but were then shut down. SpaceX will try again on another day.

The agency gave a rosy update on Artemis III, a test flight for its goal to return humans to the moon, but experts say the timeline is ambitious.

NASA has chosen four astronauts for the Artemis III mission, but there has been a major setback: the destruction of a Blue Origin rocket and its only launchpad. Our science reporter Katrina Miller describes what this event might mean for the U.S. goal of landing on the moon by 2028.

NASA’s missions these days rarely feature all-male crews. Jared Isaacman, its administrator, said women play prominent roles throughout the space agency.

The southern lights, also known as the aurora australis, were captured by the NASA astronaut Jessica Meir from the International Space Station on Saturday.

The footage of the southern lights was shared on Sunday by Jessica Meir, commander of NASA’s Crew-12 mission.

NASA announced the crew of Artemis III mission, which will fly to low-Earth orbit to test rendezvous and docking maneuvers with one or two lunar landers.

NASA’s next mission in its effort to return humans to the moon will be led by an all-male crew. Three of them have extensive experience in space, while the other was a backup on Artemis II.

Experts have been hopeful, but say the agency’s lunar aspirations are largely at the whims of two billionaires, Elon Musk and Jeff Bezos.

The Artemis III astronauts who were announced today will have had less mission training time than their Artemis II counterparts.

Almost forgotten now, the mission circled the Earth for 10 days, performing a series of tests with the lunar lander. What it lacked in glory it made up for in technological contributions.

NASA’s Artemis program has little room for error if it is to land astronauts on the moon by the end of 2028, but Blue Origin could be out of commission for at least a year.

The space agency announced that the MAVEN spacecraft, which has circled Mars for more than a decade, is being decommissioned.

The rocket, built by the Jeff Bezos-owned space company, was to carry 48 satellites into space. Blue Origin reported on social media that “all personnel have been accounted for.”
