NASA’s Space Launch System rocket stands atop pad 39B at the Kennedy Space Center. After working around a hydrogen leak at the base of the rocket, engineers spent the day Monday pumping more than 750,000 gallons of supercold liquid oxygen and hydrogen fuel into the 32-story-tall launcher in a dress rehearsal countdown. How the leak might play into plans to launch four astronauts on a moon mission as early as Sunday is not yet clear. Image: NASA

A hydrogen leak at the base of NASA’s giant SLS moon rocket Monday threw a wrench into a carefully planned countdown “wet dress” rehearsal, but engineers were able to manage a workaround and the test proceeded toward a delayed, simulated launch.

NASA fully fueled its Artemis 2 moon rocket during a crucial test today (Feb. 2) but had to pause the operation twice due to leaks. Will the agency still try to launch on Feb. 8?

"You need so much water that we think these could be evidence of an ancient warmer and wetter climate where there was rain falling for millions of years."

This is the first time humans have laid eyes on these deep space objects.

NASA's upcoming Artemis 2 moon mission is historic, but it's designed to pave the way for even bigger things.

From dazzling Jupiter high in the evening sky to elusive Mercury low at sunset, February 2026 offers one of the year's best planetary lineups.

A SpaceX Falcon 9 rocket carrying 25 Starlink satellites launched from Vandenberg Space Force Base in California on Monday, Feb. 2, 2026.

When satellites eventually fall back down to Earth, they mostly burn up because of the friction caused by the atmosphere. Scientific data about this atmospheric reentry process is urgently needed to design future satellites for a quick, safe and sustainable demise at the end of their mission – reducing risks on the ground and in space.

One of the brightest stars in the night sky will vanish as seen from North America and Europe in a rare event.
