Fresh off the first powered flight on another world, NASA's Mars 2020 mission has managed another key first that could pave the way for future astronauts.

Four astronauts are set to launch to the space station Friday. When they arrive, the new crew of 11 will be the largest since the shuttle program, and there aren't enough sleeping pods for them all.

The tiny helicopter took off and hovered briefly — the first such flight on another planet. The Perseverance rover kept tabs on the mission from a viewing point about 60 yards away.

The company beat out two others in its bid to develop a lunar lander that will bring Americans back to the moon in the coming years.

Dashcam footage and home surveillance video captured the fireball that lit up the night sky on Monday.

The successful deployment of Ingenuity brings NASA one step closer to its first attempt at testing the possibility of powered, controlled flight on another planet.

The asteroid Apophis was taken off of NASA's "risk list" after the space agency determined earlier this month that it poses no risk of impact to Earth within the next century.

NPR's Scott Simon speaks to Jason Forshaw, an aerospace engineer at Astroscale, about ELSA-d, a machine used to clean up junk in space.

The Event Horizon Telescope project, which produced the world's first image of a black hole in 2019 in the M87 galaxy, unveiled a new view of its magnetic fields as captured by polarized light.

Known as ELSA-d, the mission will exhibit technology that could help capture space junk, some of the millions of pieces of orbital debris that float above Earth.

Lunney, who played an integral role in the agency's Apollo program, died Friday. He was credited for his quick decision-making during the race to save the lives of the Apollo 13 astronauts.

Nelson, who spent six days in orbit aboard the space shuttle Columbia in 1986, would succeed Trump-era Administrator Jim Bridenstine.
