The world held its breath as NASA’s Space Launch System rocket — a 322-foot colossus — lit the Florida sky at 6:35 p.m. Eastern Time on April 1 and carried four astronauts toward the moon for the first time in more than half a century. Artemis II, lifting off from Kennedy Space Center at Cape Canaveral, marked humanity’s return to lunar space after a 54-year absence.
“We have a beautiful moonrise. We’re heading right at it,” Commander Reid Wiseman radioed back within minutes of launch — setting the tone for what NASA has called the most ambitious human spaceflight mission of the modern era.
Four Astronauts, Multiple Firsts
Aboard the Orion spacecraft, the crew carries a weight of history. Wiseman, 50, a NASA veteran and former International Space Station commander, leads the mission. Pilot Victor Glover, 49 — a US Navy aviator who flew on SpaceX’s inaugural crew rotation — becomes the first Black astronaut assigned to a lunar mission. Mission Specialist Christina Koch, 47, who holds the record for the longest single spaceflight by a woman (328 consecutive days), will be the first woman to travel toward the moon. Canadian Space Agency astronaut Jeremy Hansen, 50, a former fighter pilot, becomes the first Canadian to journey to lunar space.
What This Mission Is — And Is Not
Artemis II is not a landing mission. The crew will not touch down on the lunar surface. Instead, Orion follows a precisely calculated free-return trajectory — a looping path that uses the moon’s gravity to slingshot the capsule back toward Earth without requiring a powered burn, a safety design borrowed from the Apollo era.
At their closest approach on approximately Day 6, the astronauts will pass between 4,000 and 6,000 miles above the lunar surface — close enough to observe regions of the moon’s far side that no human eye has ever seen directly. They will travel roughly 252,000 miles from Earth, surpassing the record distance set by Apollo 13 in 1970.
“This is a test mission,” Wiseman acknowledged before launch. “And we have to be willing to take that risk.”
The 10-Day Mission Timeline
The journey unfolds across 10 carefully choreographed days. In the first 48 hours, the crew circles Earth in a high orbit, completing critical systems checks before the translunar injection burn sends Orion toward the moon. Days three and four see the spacecraft coast through cislunar space, with spacesuit tests and onboard diagnostics underway.
Day five brings the spacecraft into the moon’s gravitational sphere of influence. The following day delivers the mission’s centrepiece: the closest lunar flyby. Days seven through nine are devoted to the return journey, with medical monitoring under NASA’s ARCHER health programme continuing throughout.
On Day 10 — April 10 — Orion plunges into Earth’s atmosphere at 25,000 miles per hour. The heat shield will face temperatures reaching 5,000 degrees Fahrenheit before splashdown in the Pacific Ocean.
The Road Ahead
Artemis II is a critical stepping stone. Artemis III, planned for 2027, will dock with lunar landers from SpaceX or Blue Origin. Artemis IV, targeted for 2028, will be the first crewed moon landing since Apollo 17 in December 1972.
The mission cleared a series of pre-launch hurdles — hydrogen fuel leaks, a faulty battery sensor, a fault in the flight termination system — before the final countdown could proceed. For the four astronauts now hurtling toward the moon, and for the world watching them, the wait of a lifetime is finally over.
