Inside NASA’s Astronaut Training for a Historic Moon Mission

In just days, a group of astronauts — three Americans and one Canadian — is slated to fly roughly 5,000 miles past the far side of the moon, the farthest humans have ever traveled in space.

Their 10-day journey, the second flight of NASA’s Artemis program to create a lunar outpost as a stepping stone to Mars, will bring the crew around the moon without touching down, a precursor to the agency’s planned landing mission in 2028.
