Missions

NASA's Artemis 2 mission will launch toward to the moon in 2026. To help prepare, its four astronauts practiced observing Earth's nearest neighbor in a mockup Orion capsule.

The Expedition 73 crew on the International Space Station began their week with the arrival of an extra-large cargo delivery with new science and supplies, as well as care packages from home.

Natural geologic processes at Mars' Oxia Planum may improve the Rosalind Franklin rover's chances of detecting organic compounds.

NASA's Curiosity Mars rover has been exploring the slopes of Mount Sharp looking for clues about Mars' watery past. Here, it looks at the boxwork pattern for ancient water flow.

Northrop Grumman's new "Cygnus XL" cargo ship reached the International Space Station this morning (Sept. 18), after a delay, delivering about 11,000 pounds of supplies to the orbiting lab.

Artemis 2 astronauts will be the subjects of nearly as many experiments as they'll be performing during their trip around the moon.

A new study suggests that a group of cells, key for the health of blood and the immune system, are vulnerable to aging-like processes after spending time on the ISS.

NASA plans to send the ISS into Earth's atmosphere in 2030, and it has no plans for a replacement — at least, not directly.

Northrop Grumman's new "Cygnus XL" cargo ship won't arrive at the ISS on Wednesday morning (Sept. 17) as planned after suffering a thruster issue in orbit.

NASA is working on finding landing sites for future moon astronauts. Part of the work includes thinking about how to prepare for eventual Mars missions with astronauts.
