Four astronauts are about to venture farther from Earth than any humans ever have. Want to follow along with them as they travel a quarter-of-a-million miles away on NASA's trailblazing Artemis II moon mission?
Lucky for you, the U.S. space agency has an app for that. And a desktop website, too.
After potentially launching April 1 from the Kennedy Space Center in Florida, the astronauts are due to pilot an Orion crew capsule on a 10-day journey around the moon and back. The second under NASA's multibillion-dollar Artemis program, the mission will pave the way for a moon landing as early as 2028.
