Artemis II Astronauts Break Free of Earth Orbit, Begin Journey Toward Moon

The Artemis II mission’s four astronauts fired their engines and left Earth orbit late Thursday, becoming the first humans to head toward the moon since the Apollo era ended in 1972. Launching from Cape Canaveral, Florida, the crew performed a critical translunar injection 25 hours after liftoff, propelling their Orion capsule onto a trajectory that will take them nearly 250,000 miles from Earth.

NASA confirmed the engine burn was executed flawlessly, setting astronauts Reid Wiseman, Victor Glover, Christina Koch, and Canadian Jeremy Hansen on a course for a lunar flyby expected early next week. “Human beings have left Earth orbit,” announced NASA’s Lori Glaze at a news conference, highlighting the milestone after decades of low Earth orbit missions since Apollo 17.

The crew spent their first day in orbit conducting life-support system tests before Mission Control authorized the departure maneuver. During the burn, the Orion capsule accelerated to around 24,000 mph, breaking free of Earth’s gravitational pull in what NASA termed “humanity’s lunar homecoming arc.” The mission will take them 4,000 miles beyond the moon before Orion turns back toward Earth, offering the farthest excursion by humans in history—surpassing Apollo 13’s 1970 record.

Artemis II marks a series of firsts: Glover, Koch, and Hansen are the first Black astronaut, first woman, and first non-U.S. citizen, respectively, to embark on a lunar mission. The crew reported “phenomenal” views as they left Earth behind and are expected to witness a total solar eclipse from space during their journey.

The mission is central to NASA’s Artemis program, aimed at establishing sustained lunar presence and a future moon base. The next milestone will be Monday’s lunar flyby. The Orion capsule encountered minor issues, including a malfunctioning toilet and a water valve concern, both managed by the crew and Mission Control, ensuring crew safety and mission progress.

The Artemis II crew remains in good spirits as they continue their pioneering test flight, with all systems reported stable ahead of the upcoming lunar approach.
