NASA Artemis II Moon Mission: Trans Lunar Injection Maneuver Explained

NASA Artemis II Moon Mission: Trans Lunar Injection Maneuver Explained

Artemis II Mission Specialist Christina Koch talks about the amazing maneuver that will propel the Orion spacecraft and its crew around low Earth orbit, towards the Moon, and home again.  Known as TLI, or Trans Lunar Injection, this single event sets the path for the entire Artemis II mission.

NASA’s Space Launch System (SLS) rocket carrying the Orion spacecraft with NASA astronauts Reid Wiseman, commander; Victor Glover, pilot; Christina Koch, mission specialist; and Canadian Space Agency (CSA) astronaut Jeremy Hansen, mission specialist onboard, was successfully launched at 6:35 p.m. EDT Wednesday, April 1, 2026, for the Artemis II Mission from Launch Complex 39B at NASA’s Kennedy Space Center in Florida.

NASA’s Artemis II Mission will take Wiseman, Glover, Koch, and Hansen on a 10-day journey around the Moon and back aboard their Orion spacecraft.
