The White House has announced that NASA will work with the Departments of Defense and Energy to put nuclear reactors in orbit and on the surface of the moon.

The astronauts will arrive about 10,300 kilometers beyond our satellite, breaking all previous records for distance from Earth. But how was their route chosen?

The mission commander’s email inbox failed during the journey to the moon. Have they tried turning the computer off and back on again?

Companies hope that biometric age-verification tech in cartridges could put flavored vapes back in business. But it's unlikely to solve the real problems.

Unitree is bringing its R1 to international markets. It arrives with some aerobatic capabilities and an entry-level price, but the question of what you'd actually do with it remains open.

The crew of Artemis II will not descend to the moon, but their capsule will fly over the far side of its surface.

Take a group of runners circling a track at unique, constant paces. Answering the question of how many will always end up running alone, no matter their speed, has vexed mathematicians for decades.

The moon gets hit by space debris all the time, but some of it is so large that the impact generates light that can be seen thousands of kilometers away.
