NASA directed five astronauts to board a docked Dragon spacecraft as cosmonauts attempt to address a leak on the International Space Station, a NASA press secretary said Friday.

NASA's X-59 jet broke the sound barrier for the first time on Friday (June 5), reaching a top speed of about Mach 1.1.

NASA astronauts temporarily sheltered June 5 in a docked SpaceX Dragon spacecraft as crews repaired new air leaks on the International Space Station.

NASA’s PExT terminal has shown that spacecraft can seamlessly communicate through multiple government and commercial networks, a major step beyond traditional single-network systems. The mission is now expanding to test new capabilities that could help create a more flexible,

NASA astronauts briefly sheltered in their SpaceX Crew Dragon capsule on Friday during a Russian repair attempt on a leaky transfer tunnel of the International Space Station. The work was later halted for further analysis, and the crew resumed their normal tasks on the space station, which orbits about 250 miles above Earth.

NASA just declared its MAVEN Mars orbiter dead after a dozen productive years circling the Red Planet. Here's the fate that awaits the probe.

In the name of science, those researchers will test the limits of a mobile wastewater treatment system designed to convert human waste into plant nutrients and other sustainable materials. The trial will serve as a stress test of sorts,

Almost six months after NASA lost contact with the spacecraft, the agency has declared the MAVEN satellite unrecoverable and its mission concluded.

It could be more than a year before Blue Origin's New Glenn is ready to fly again, but NASA has no intention of letting the Artemis timeline slip.

Every day, a NASA program quietly recalculates the orbits of thousands of space rocks and flags each one that will pass within roughly 4.6 million miles of Earth. That distance, about 19.5 times the gap between Earth and the Moon,
