As of April 1, 2026, at approximately 7 PM EDT, NASA’s Artemis II mission has lifted off from Launch Complex 39B at Kennedy Space Center in Florida. The Space Launch System (SLS) rocket carrying the Orion spacecraft and its four-person crew successfully departed at 6:35 p.m. EDT (22:35 UTC), marking the first crewed lunar mission since Apollo 17 in December 1972.
The launch occurred within the two-hour window that opened at 6:24 p.m. EDT, following a smooth countdown that began two days earlier. Weather conditions were favorable (upgraded to 90% “go” probability), and a minor pre-launch concern with a Launch Abort System battery temperature reading was resolved as an instrumentation issue.
The Crew: An International Team Poised for History
Commanding the mission is NASA astronaut Reid Wiseman, with Victor Glover as pilot. Mission specialists include NASA’s Christina Koch and Canadian Space Agency (CSA) astronaut Jeremy Hansen. This diverse crew represents a key step in NASA’s Artemis program, which emphasizes international collaboration and inclusivity in lunar exploration.
The astronauts, wearing custom-fitted bright orange spacesuits designed for improved safety and mobility, boarded Orion earlier in the day after final preparations and a walkout from the Neil Armstrong Operations and Checkout Building.
Mission Objectives and Trajectory
Artemis II is a critical uncrewed-to-crewed test flight. Unlike Artemis I (the 2022 uncrewed test), this mission sends humans aboard Orion for a roughly 10-day journey that will take them on a free-return trajectory around the Moon. Key milestones include:
- Lunar flyby around April 6, with the spacecraft approaching within about 6,000 miles (roughly 9,600 km) of the lunar surface.
- Reaching a distance of more than 4,600 miles (7,400 km) beyond the far side of the Moon – potentially setting a new record for the farthest humans have traveled from Earth, surpassing the Apollo 13 mark.
- Testing Orion’s life support systems, navigation, communication, and heat shield performance in the deep-space environment.
- Validating the SLS rocket’s performance with a crew aboard for the first time.
The mission will not include a lunar landing; that is planned for 2028 or later. Instead, Artemis II focuses on verifying systems for future sustained human presence on and around the Moon.
After the flyby, Orion will return to Earth, with a planned splashdown in the Pacific Ocean off the coast of San Diego around April 10, 2026.
Technical Challenges Overcome
The road to launch was not without hurdles. Earlier attempts faced setbacks, including a liquid hydrogen leak during a February fueling test and a helium flow issue in the upper stage that pushed the target from March into April. Engineers addressed heat shield concerns identified after Artemis I and conducted thorough risk assessments during the Flight Readiness Review.
Today’s countdown proceeded with propellant loading (tanking operations) beginning in the morning, and the team resolved the final minor technical item efficiently.
Significance for the Artemis Program and Beyond
Artemis II represents a pivotal moment in humanity’s return to the Moon. It builds on the success of Artemis I and paves the way for Artemis III, which aims to land the first woman and first person of color on the lunar surface near the south pole. Long-term goals include establishing a sustainable lunar presence, developing technologies for Mars missions, and fostering commercial and international partnerships.
The European Space Agency contributed the Orion Service Module, highlighting the collaborative nature of the program.
As the SLS rocket’s engines roared to life and the solid rocket boosters ignited, carrying the crew into the Florida evening sky, millions watched – either in person along the Space Coast or via NASA’s live broadcasts. The thunderous ascent signaled not just a launch, but the reopening of deep space to human explorers.
With Artemis II now underway, the focus shifts to monitoring the crew’s health, spacecraft performance, and the upcoming lunar encounter. NASA provides continuous updates as the mission progresses.
This successful liftoff underscores the progress made since the Space Shuttle era and reignites the spirit of exploration that defined the Apollo program. The New Space Economy is watching closely as public-private partnerships and international efforts accelerate humanity’s multi-planetary future.
Godspeed to the Artemis II crew – Reid, Victor, Christina, and Jeremy. Safe travels around the Moon and back.
