HOUSTON—Astronauts are back in lunar space for the first time in more than 50 years.
Artemis II’s Orion spacecraft, Integrity, crossed into the Moon’s gravitational influence at approximately 12:41 a.m. ET on April 6, officially making NASA’s Reid Wiseman, Victor Glover, and Christina Koch, as well as the Canadian Space Agency’s Jeremy Hansen, the first astronauts to enter lunar space in more than half a century.
