In a major leap for human spaceflight, Nasa’s Artemis II mission successfully executed a critical engine burn late Thursday, sending its crew out of Earth’s orbit and onto a path toward the moon.The trans-lunar injection took place about 25 hours after liftoff, placing three American astronauts and one Canadian on course for a lunar flyby early next week. The Orion spacecraft departed Earth’s orbit exactly as planned, beginning its nearly 400,000-kilometre journey into deep space.“This is the first time since 1972, during Apollo 17, that humans have left Earth’s orbit,” said NASA official Lori Glaze, confirming the maneuver was flawless.Canadian astronaut Jeremy Hansen described the crew as “glued to the windows,” captivated by the shrinking view of Earth and the vastness beyond. “It’s a phenomenal sight,” he said, calling the mission a reflection of humanity’s shared ambition.After spending a day in Earth orbit testing life-support systems, the crew was cleared to proceed toward the moon. The mission marks a crucial step in Nasa’s long-term goal of establishing a sustained human presence on the lunar surface.Commander Reid Wiseman, pilot Victor Glover, mission specialist Christina Koch, and Hansen will loop around the moon before returning to Earth, without landing. During the mission, they are expected to travel farther from Earth than any humans before, surpassing the record set during Apollo 13 in 1970, and could also set a new speed record during reentry on April 10.The flight is already historic: Glover, Koch, and Hansen are the first Black astronaut, the first woman, and the first non-American to travel to the moon—marking a significant shift from the all-male, all-white Apollo-era crews.Mission Control set the tone with a musical wake-up call before giving final clearance for the engine burn, describing the journey as “humanity’s lunar homecoming.” The spacecraft is now following a free-return trajectory, using the gravity of Earth and the moon to complete its figure-eight path.The next milestone will come with Monday’s lunar flyby, when Orion will pass roughly 6,400 kilometres beyond the moon, offering rare views of its far side. The astronauts are also expected to witness a total solar eclipse from space.Despite the milestone, the mission has not been without minor hiccups. A malfunction in the spacecraft’s toilet system required improvised fixes, while cold cabin temperatures forced the crew to bundle up. Engineers also addressed a water dispenser issue by instructing astronauts to fill backup storage bags with drinking water.Nasa hopes Artemis II will pave the way for future lunar landings, including a planned crewed mission to the moon later this decade—marking the beginning of a new era of human exploration beyond Earth.
