NASA reportedly paid SpaceX $5 million to make sure its employees didn’t use illegal drugs after Elon Musk smoked pot on camera

Experts told Politico there is no clear precedent for NASA paying a contractor to conduct an internal review similar to the one SpaceX is undergoing.
The story of NASA's "missing" Lunar Module 14 likely ended in tragedy, and perhaps a rebirth.

NASA isn’t sure what happened to one of its last Apollo moon landers. The truth is probably depressing.

Grumman Aircraft designed and built lunar modules for NASA during the Apollo program. A handful never made it to space, though.

Earth is screaming through space at 1.3 million mph. A simple animation by a former NASA scientist shows what that looks like.

Earth orbits the sun, which orbits the center of the Milky Way galaxy, which is itself barreling through space.

A huge explosion sliced through our galaxy just 3.5 million years ago, as human ancestors walked the Earth. Scientists think it was nuclear activity i...

NASA's Hubble telescope found traces of the explosion in a gas stream beyond the Milky Way, "dramatically" changing scientists' view of our galaxy.
A space craft named "Soyuz MS-15" takes off for the International Space Station with meat cells onboard.

Astronauts just printed meat in space for the first time — and it could change the way we grow food on Earth

A spacecraft with vials of cow cells landed at the International Space Station in September. From there, cosmonauts fed the vials into a 3D printer.

Warp speeds in ‘Star Trek’ are achingly slow, and a simple animation by a former NASA scientist proves it

The animation shows how long it takes the starship Enterprise in "Star Trek" to reach Pluto at warp factors that break the known laws of physics.

Elon Musk’s new Starship would be a monster rocket if built. Here’s how the SpaceX launch system compares to NASA’s 2 biggest rocket...
