NASA's Artemis II Moon Mission: Launch Dates, Crew, and What to Expect

NASA Eyes April 2026 for Historic Crewed Moon Mission

For the first time in more than half a century, human beings could soon be journeying around the Moon. NASA has set its sights on an early April 2026 launch for Artemis II — a roughly 10-day crewed mission that will send four astronauts deeper into space than any humans have ever traveled before.

The mission marks a pivotal step toward eventually landing astronauts on the lunar surface, something that hasn't happened since the final Apollo missions of the early 1970s.

Available Launch Windows for Artemis II

NASA has identified several potential launch dates in April 2026, including April 1, 2, 3, 4, 5, 6, and 30. The agency had originally hoped to launch before the end of 2024, but a series of technical setbacks pushed that timeline back considerably.

An attempted February launch was abandoned after hydrogen fuel was found leaking from a connection between the launch tower and the rocket during a pre-flight wet dress rehearsal. A March window was subsequently ruled out following the discovery of a separate helium leak.

Beyond fixing technical problems, mission planners must also align launches with the Moon's orbital position. This creates a roughly one-week window at the beginning of each month during which a launch is feasible, followed by approximately three weeks with no viable opportunities.

Meet the Artemis II Crew

Artemis II will carry four crew members into space:

• Reid Wiseman — NASA Mission Commander
• Victor Glover — Pilot
• Christina Koch — NASA Mission Specialist
• Jeremy Hansen — Mission Specialist, Canadian Space Agency

This crew will make history as the first humans to ride aboard NASA's massive Space Launch System (SLS) rocket paired with the Orion space capsule on a crewed flight.

What Will the Crew Actually Do?

Once the spacecraft reaches orbit, the astronauts will put Orion through its paces. Early activities will include manually piloting the capsule in Earth orbit to practice critical maneuvers such as steering and spacecraft alignment — skills that will be essential for future lunar landing missions.

The crew will then venture thousands of kilometers beyond the Moon to conduct thorough evaluations of Orion's life-support systems, propulsion capabilities, power supply, and navigation accuracy.

In addition to technical testing, the crew members will serve as medical research subjects, transmitting health data and imagery from deep space back to scientists on Earth. They will live and work in a compact cabin under weightless conditions, exposed to radiation levels higher than those on the International Space Station — though still within safe limits.

The mission concludes with a fiery re-entry through Earth's atmosphere and a splashdown in the Pacific Ocean off the west coast of the United States.

Is Anyone Landing on the Moon This Time?

Not yet. Artemis II is a critical preparatory mission, not a lunar landing. The actual crewed Moon landing is planned for Artemis IV in 2028, targeting the Moon's south pole.

Before that, Artemis III — currently scheduled for 2027 — will serve as a dress rehearsal, testing Orion's ability to rendezvous and dock with lunar landers and evaluating next-generation spacesuits if they are ready in time.

NASA has selected two commercial partners to develop lunar landers for the program: SpaceX's Starship and a vehicle built by Blue Origin, the aerospace company founded by Jeff Bezos. The agency will determine which lander flies which mission closer to launch.

The Long-Term Vision: A Permanent Human Presence on the Moon

Artemis IV won't be the end of the story. NASA envisions a fifth mission — Artemis V — later in 2028, aimed at building the infrastructure for sustained human habitation on the Moon. Plans include the development of a lunar base, surface habitat modules, and robotic rovers.

While NASA has paused work on its proposed Gateway orbital station, the broader goal remains: establishing a permanent human foothold on the Moon that grows over time.

International partners are central to this vision. European astronauts are slated to join later Artemis missions, and Japan has secured seats on future flights. Additional nations are expected to contribute as the program expands.

Why Return to the Moon Now?

The last humans to walk on the Moon were the crew of Apollo 17, who landed in December 1972. In total, 24 astronauts have traveled to the Moon, 12 of whom walked on its surface. Of those 24, only five remain alive today.

The original Moon race of the 1960s was driven largely by Cold War competition — the United States sought to assert technological and geopolitical superiority over the Soviet Union. Once that objective was achieved, political will and funding dried up.

Artemis is different in its ambitions. Rather than a one-time achievement, it is designed around long-term exploration, cutting-edge technology, and deep commercial partnerships. The goal is not simply to revisit the Moon, but to stay.

China is also pursuing its own lunar ambitions, with plans to land astronauts near the Moon's south pole by 2030, adding a new dimension of international competition to the modern space race.

With multiple nations and private companies now invested in the Moon's future, the next era of lunar exploration promises to be broader, more sustained, and more consequential than anything that came before it.
