Artemis II: NASA’s First Crewed Lunar Flyby in Half a Century
Humanity is once again venturing toward the Moon. On April 1, 2026, NASA launched the Artemis II mission, marking the first time astronauts have flown aboard the Space Launch System (SLS) rocket and the Orion spacecraft. This 10-day mission is a critical test of deep-space capabilities, serving as the bridge between the uncrewed Artemis I mission and future goals of landing humans on the lunar surface and eventually reaching Mars.
The Mission Objectives
Artemis II is designed as a crewed flight test of the Orion spacecraft beyond low Earth orbit. Rather than landing, the crew is performing a lunar flyby, traveling around the Moon and returning safely to Earth. This allows NASA to test how the spacecraft’s systems operate in a deep-space environment and ensures the crew can be sustained during long-duration missions.
The mission is expected to cover a total distance of 695,081 miles from launch to splashdown. During the flight, the crew will pass within approximately 4,700 miles (7,600 km) of the Moon.
Meet the Artemis II Crew
The mission is crewed by four astronauts, representing a collaboration between NASA and the Canadian Space Agency (CSA):
- Reid Wiseman: NASA Astronaut
- Victor Glover: NASA Astronaut
- Christina Koch: NASA Astronaut
- Jeremy Hansen: Canadian Space Agency (CSA) Astronaut
The Hardware: SLS and Orion
The mission relies on two primary pieces of hardware developed for deep-space exploration:
- The Space Launch System (SLS): NASA’s heavy-lift rocket, which provided the power necessary to propel the crew out of Earth’s orbit.
- The Orion Spacecraft: Specifically the Orion CM-003 Integrity and ESM-2. Orion serves as the exploration vehicle that sustains the crew and is designed to return them safely to Earth via a splashdown in the Pacific Ocean.
Mission Timeline and Current Status
The journey began at 6:35 p.m. EDT on April 1, 2026, launching from Launch Complex 39B at the Kennedy Space Center in Florida. As of April 5, the mission is in progress, with the crew having already completed outbound trajectory correction burns and prepared the cabin for the lunar flyby.
The crew is scheduled to return to Earth with a planned splashdown off the coast of San Diego on April 11, 2026.

Frequently Asked Questions
How does Artemis II differ from Artemis I?
While Artemis I was an uncrewed mission in 2022 that tested the SLS and Orion, Artemis II is the first to carry a human crew to demonstrate the capabilities needed for deep space missions.
Where will the astronauts land?
The Orion spacecraft is planned to land in the Pacific Ocean, completing the mission with a safe splashdown.
What happens after Artemis II?
This mission paves the way for subsequent Artemis missions, which aim to return humans to the lunar surface and eventually establish a long-term presence on the Moon as a stepping stone for future missions to Mars.
For those following the mission in real-time, NASA provides daily status briefings and live streams from the Orion spacecraft as bandwidth allows.
