Officials have directed the space agency to pause funds for a host of science missions the White House originally pushed to cancel in its 2026 budget request, according to a letter sent to the agency’s centers from NASA headquarters and obtained by POLITICO.

NASA associate administrator Amit Kshatriya and associate administrator of NASA Science Dr. Nicky Fox explain that "all evidence points" that is an interstellar comet and reveal a new image from the Mars Reconnaissance Orbiter (MRO).

Mars has long tempted scientists with hints of chemistry that might once have supported life. Now a NASA-led study argues that the complex organic molecules hidden in ancient Martian rocks are very difficult to explain without some kind of biological help.

A SpaceX rocket launched on Friday headed to the International Space Station for an eight-month science mission, NASA reported in a statement.

Artemis II, the next mission in NASA’s Artemis program to explore the Moon, is scheduled to launch from Florida within the coming weeks. The mission will be the first crewed mission to the vicinity of the Moon since 1972, with the four-person crew expected to travel farther than any other human mission in spaceflight history.

Two new satellite missions will help NASA scientists better understand Earth and improve the ability to foresee environmental events and mitigate disasters. And the agency says they’ll be

To avoid Swift being dragged down low enough to hit Earth’s atmosphere, NASA tapped an Arizona-based startup to launch a rescue mission. Late last year, NASA awarded Katalyst Space Technologies $30 million to develop a spacecraft designed to boost Swift’s orbit.

NASA is inviting the public to join 36 citizen science projects. Volunteers can help with discoveries from asteroids to Martian clouds. To join, email do-nasa-science-join@lists.nasa.gov with "Subscribe." NASA is allowing everyday citizens to take part in ...

Bill Nye let a packed crowd at the Orange Convention Center know that it’s not a good idea to send a human on a one-way trip to Mars. “Although there’s a few I wouldn’t mind,” he said earning another chuckle during his hour-long,

Anticipated summer launch is cutting it fine NASA has ended most science operations on its Swift observatory to keep the spacecraft in orbit a little longer.… The 21-year-old observatory's altitude has now dropped below 250 miles (400 kilometers) - it needs to sit above 185 miles (about 300 kilometers) to maximize the chances of an anticipated reboost mission.
