NASA’s Artemis program, aiming to return humans to the lunar surface, faces an unexpected yet critical threat: meteor storms. As humanity prepares to venture beyond Earth orbit, tiny yet high-speed micrometeoroids could challenge the safety and timing of lunar missions.

Three Americans and an Italian have been named as the crew members for NASA's next mission in the Artemis moon programme.

It will include a retired Marine Colonel, an astronaut from the European space agency, a physician, and another astronaut who will make his first spaceflight.
