Apollo 17 astronauts take the Moon Buggy out for a spin.
Houston: The photographs have surfaced.
While rummaging around Johnson Space Center, PISCES executive director Rob Kelso recently came across previously unpublished images of astronauts trekking across Apollo Valley on Hawaii’s Big Island in the late 1960s and early ’70s. Similar to the surface of the moon, the island’s volcanic, rocky landscape was ideal for testing moon buggies and training astronauts.
Yesterday, NASA’s Pacific Space Center released these photos from Apollo training missions 13, 15, and 17. Among them:
