Artemis II Carries Astronauts around the Moon

Artemis II launched from Kennedy Space Center at 6:35 p.m. Eastern on April 1, 2026. Four astronauts rode NASA’s Space Launch System rocket and Orion spacecraft on a nearly ten-day journey around the Moon.

The mission carried Reid Wiseman, Victor Glover, Christina Koch and Canadian astronaut Jeremy Hansen. They became the first people to travel to lunar distance since Apollo 17 left the Moon in December 1972.

A test flight with people aboard

Artemis I had sent an uncrewed Orion around the Moon in 2022. Artemis II added the systems, procedures and judgment required when human lives are on board. It was a test, not a landing mission.

The crew evaluated life support, displays, manual control, communications, navigation and daily spacecraft operations. Ground controllers could monitor data and send commands, but delays and distance require crews to recognize problems and act without depending on immediate help.

Space Launch System used a core stage and two solid rocket boosters to lift Orion into Earth orbit. The upper stage then performed a translunar injection burn, supplying the energy to leave Earth and begin the lunar trajectory.

Before departing, the astronauts practiced proximity operations by using their spent upper stage as a target. That exercise tested handling qualities relevant to future docking and rendezvous tasks.

Following a free-return path

Orion traveled on a free-return trajectory. The route used the Moon’s gravity to turn the spacecraft back toward Earth, providing a basic return path even if a major propulsion problem occurred after the outbound burn.

During the April 6 flyby, Orion passed 4,067 miles above the lunar surface. The spacecraft reached 252,756 miles from Earth at its most distant point, farther than any crewed vehicle had traveled previously.

The crew photographed the surface, earthrise and earthset and a solar eclipse seen from Orion. NASA reported more than 7,000 lunar images. Observations included terrain near the day-night boundary, where long shadows resemble lighting conditions around polar regions of interest for later exploration.

No one stepped onto the surface, and Orion did not enter a lasting lunar orbit. Those distinctions matter because a flyby tests different systems and carries different risk from descent, landing and launch from the Moon.

The crew and their milestones

Wiseman served as commander and Glover as pilot. Koch and Hansen were mission specialists. All four had trained for years on spacecraft systems, emergency procedures, geology and survival after landing.

Glover became the first Black astronaut to travel to lunar distance. Koch became the first woman to do so, and Hansen the first non-American. Their milestones reflected decades of change since the Apollo crews, who were all American men.

The Canadian seat also reflected the international nature of Artemis. Canada contributes Canadarm3 robotics to the planned Gateway lunar station, while European partners provide Orion’s service module and other nations participate through hardware and science.

International partnership spreads cost and expertise but also creates dependencies and complex schedules. Artemis remains NASA-led, while its mission architecture includes commercial lunar landers and contributions from multiple agencies.

Returning through Earth’s atmosphere

Orion approached Earth at lunar-return speed, placing intense heat on the spacecraft’s protective shield. Atmospheric drag slowed the capsule before parachutes deployed for the final descent.

The spacecraft splashed down in the Pacific Ocean off California at 5:07 p.m. Pacific on April 10. Recovery teams secured the capsule, and the crew underwent immediate medical evaluation before returning to Houston.

Reentry was one of the mission’s critical tests. Artemis I had revealed unexpected patterns in how heat-shield material was released. NASA studied that behavior and changed the Artemis II entry trajectory and operating procedures rather than treating the first test as a final answer.

Postflight work included medical monitoring, engineering inspection and science debriefs. A successful splashdown completed the flight, but certification depends on detailed review of data and hardware after public attention moves on.

What Artemis II did—and did not prove

The mission demonstrated that SLS and Orion could carry a crew through launch, deep-space operations and high-speed return. It supplied experience no simulator can fully reproduce and tested teams across launch, mission control, communications and recovery.

It did not prove that NASA was ready to land astronauts on the Moon. Landing requires a separate spacecraft, spacesuits, surface systems, docking operations and mission plans more complicated than a flyby. Schedules for later Artemis flights have changed as those elements mature.

The 2026 calendar places launch on April 1 and return on April 10. Readers checking weekdays can use the day-of-week calculator for any mission milestone. The moon phases guide explains the cycle of lighting that affects surface observation and mission planning.

Artemis II’s achievement was specific and substantial: people rode a new American spacecraft beyond low Earth orbit, worked around the Moon and returned safely. It restored a capability absent for more than half a century while leaving the harder task of landing for missions still ahead.
