Space Exploration

NASA's plan to build a train track on the moon is part of the agency's Innovative Advanced Concepts program, which aims to develop "science fiction-like" projects for future space exploration.

Aurora-hunting photographers were surprised to spot a misshaped SpaceX spiral with ethereal horns over Europe during a recent geomagnetic storm.

A tiny, previously undisclosed lunar rover has been spotted strapped to the side of China's moon-bound Chang'e 6 lander in newly released pre-launch photos. The true purpose of the rover, which is scheduled to land on the moon's far side, remains a mystery.

The first crewed launch of Boeing's Starliner space capsule was canceled on Monday (May 6) due to a loudly buzzing valve on the Atlas V rocket carrying it. The delay is yet another headache for Boeing in its attempt to get its Starliner capsule up and running.

A new Japanese mission to photograph space junk from orbit marks a milestone in orbital debris cleanup efforts.

The Infra-Red Calibration Balloon (S73-7) satellite had gone off the grid from radar not once but twice — once in the 1970s and then again in the 1990s. After 25 years missing in orbit, it has finally been rediscovered.

Flaring stars, black hole outbursts and gamma-rays are just some of the cosmic exotica that Einstein Probe will hunt for.

Chinese astronomers have shared the most detailed geological map of the moon ever created, revealing more than 12,000 structures. The new atlas will be essential for picking out landing locations and resource sites for future lunar missions.

On April 10, a bright red atmospheric "hole" was spotted in the night sky above Texas shortly after SpaceX launched 23 Starlink satellites into space. It is the latest example of an increasingly common phenomenon caused by the company's dying rockets.

NASA's Voyager 1 probe has resumed sending usable data back to Earth after engineers fixed a computer error that caused the interstellar spacecraft to only transmit gibberish for five months.
