An engineering development version of the NASA rovers currently operating on Mars takes a spin at the Jet Propulsion Laboratory in California. (NASA via YouTube) NASA is considering repurposing an engineering development version of the nuclear-powered Mars rovers for a different destination: the moon’s south polar region.

It’s sometimes easy to overlook the fact that the International Space Station (ISS) is a giant lab where scientists study everything from biology to physics—but in space. This extraordinary resource makes extraordinary research possible—like creating a fifth state of matter in space.

NASA astronauts Chris Williams and Jessica Meir completed a 7-hour, 20-minute spacewalk Tuesday to replace a malfunctioning wrist joint on the International Space Station's Canadarm2 robotic arm.

As part of plans to establish a lunar base, the space agency may send to the moon a spare test version of the rover — as well as a soccer ball.

Following an initial frenzy a decade ago, the commercial space sector is getting a new wave of investment. This time, things are markedly different, experts say.

NASA’s recent cancellations of four Artemis programs — including the mobile launcher 2 tower that was constructed at Kennedy Space Center — were projected to cost the agency billions more if they had

The post, shared by astronaut Don Pettit, included a timelapse capturing the brief but beautiful moment.

Future missions to the Moon, Mars, and beyond may no longer need to carry every drop of propellant from Earth. NASA has successfully tested an advanced cryocoupler, a specialized connection system designed to transfer ultra-cold rocket propellants between spacecraft in orbit.
