Physicists trap antimatter electron as JAXA readies Phobos rover mission
A new experiment has successfully confined the electron’s antimatter counterpart, and JAXA’s upcoming MMX mission will feature the first rover to drive in Phobos’s ultra-low gravity.
Why it matters
Trapping antimatter electrons advances fundamental physics, while JAXA's rover could revolutionize low-gravity exploration of Phobos.
