Artemis II marked a major milestone in human spaceflight when it lifted off on April 1, 2026. This was NASA’s first crewed mission in the Artemis program, sending four astronauts on a 10-day journey around the Moon and back—the first time humans traveled beyond low Earth orbit since Apollo 17 more than 50 years earlier. The successful launch at 6:35 p.m. EDT from Kennedy Space Center and safe return on April 10 showed how far technology has come and set the stage for future lunar landings.
What Is Artemis II?
Artemis II was the second flight in NASA’s Artemis campaign and the first with a crew aboard the Orion spacecraft. Its main goal was to test every system that will one day carry astronauts to the lunar surface and eventually to Mars. Unlike uncrewed test flights, this mission put real people in deep space to check life support, navigation, and re-entry systems under real conditions. The entire flight covered more than 685,000 miles and gave engineers critical data for the next steps in lunar exploration.

Launch Date and Timeline
The Artemis II launch date was April 1, 2026, at exactly 6:35 p.m. EDT. The two-hour launch window opened right on schedule, and the SLS rocket performed flawlessly. After liftoff, the crew spent the first day in a high Earth orbit before heading toward the Moon. The journey included a close flyby of the lunar far side at about 4,000 miles from the surface. The crew splashed down safely in the Pacific Ocean on April 10, 2026, after a textbook re-entry at nearly 30 times the speed of sound.
Meet the Artemis II Crew
The four astronauts chosen for this historic flight brought a wealth of experience:
- Commander Reid Wiseman – NASA astronaut and veteran of the International Space Station
- Pilot Victor Glover – NASA astronaut who flew on SpaceX Crew-1
- Mission Specialist Christina Koch – NASA astronaut who holds the record for the longest single spaceflight by a woman
- Mission Specialist Jeremy Hansen – Canadian Space Agency astronaut making his first spaceflight
This international crew highlighted the growing global partnership in space exploration. For more on crew preparation, check how astronauts train for Artemis II mission.
SLS Rocket and Orion Spacecraft
At the heart of the mission was NASA’s Space Launch System (SLS) Block 1 rocket—the most powerful ever built for human spaceflight. It generated 8.8 million pounds of thrust at liftoff and stood taller than the Statue of Liberty. Riding on top was the Orion spacecraft, designed to carry four astronauts safely to the Moon and back. You can learn more technical details in our article on Space Launch System SLS rocket power and specs and Orion spacecraft features and technology.
The 10-Day Lunar Journey
Once in space, the crew followed a figure-eight path around Earth and the Moon. They performed several engine burns to reach lunar distance, flew behind the Moon (out of radio contact with Earth for about 45 minutes), and captured stunning views of the lunar far side. The mission tested communication systems, radiation shielding, and the Orion heat shield that protected the crew during the fiery return to Earth.

Apollo vs Artemis: Key Differences
While Artemis II followed a similar lunar flyby path to early Apollo test flights, the technology and goals are very different. The SLS and Orion are designed for longer stays and sustainable exploration.
