With NASA's Artemis II mission on the verge of launching as early as April 1, 2026, the four astronauts selected for humanity's first crewed journey beyond low-Earth orbit in more than 50 years are drawing global attention. Commander Reid Wiseman, pilot Victor Glover, mission specialist Christina Koch and Canadian Space Agency astronaut Jeremy Hansen arrived at Kennedy Space Center on March 27 for final preparations, stepping into a pivotal role that will test the Orion spacecraft and pave the way for future lunar landings.

Here are 10 essential things to know about the Artemis II crew as they prepare for an approximately 10-day flight that will send them looping around the Moon on a free-return trajectory.

1. Diverse Crew Marks Historic Firsts

The Artemis II crew represents a deliberate step toward broader representation in deep-space exploration. Glover will become the first Black astronaut to travel to the vicinity of the Moon. Koch will be the first woman to venture that far from Earth. Hansen will be the first non-American and first Canadian to fly on a lunar mission. Wiseman, a veteran commander, rounds out the international team. Their selection moves beyond the Apollo era's narrow demographic of mostly White American male military pilots.

2. Reid Wiseman: Navy Test Pilot and Mission Commander

Reid Wiseman, a U.S. Navy test pilot selected by NASA in 2009, will command the mission. He previously spent 165 days aboard the International Space Station in 2014. A single father, Wiseman brings leadership experience and calm under pressure to the crew. He has described the mission as a critical test flight that will gather essential data for future Artemis landings. Wiseman and his crewmates flew T-38 jets from Houston to Kennedy Space Center on March 27 as final countdown activities intensified.

3. Victor Glover: First Black Astronaut Headed to Deep Space

Victor Glover, a naval aviator and test pilot selected in 2013, serves as pilot. He flew aboard the SpaceX Crew-1 mission to the ISS in 2020-2021, becoming the first Black astronaut to spend an extended period on the station. On Artemis II, Glover will make history again as the first person of color to travel beyond low-Earth orbit toward the Moon. His perspective emphasizes the mission's role in inspiring future generations from diverse backgrounds.

4. Christina Koch: Record-Holding Astronaut and First Woman to the Moon

Christina Koch, an electrical engineer selected in 2013, holds the record for the longest single spaceflight by a woman — 328 days aboard the ISS in 2019-2020. She also participated in the first all-female spacewalk. As a mission specialist on Artemis II, Koch will become the first woman to fly around the Moon. Her engineering expertise and endurance in space make her a key contributor to testing Orion's life-support and operational systems during the flight.

5. Jeremy Hansen: Canada's First Deep-Space Astronaut

Jeremy Hansen, a fighter pilot and colonel in the Canadian Armed Forces, was selected by the Canadian Space Agency in 2009. He will become Canada's first astronaut to travel beyond low-Earth orbit. Hansen has trained extensively with his NASA crewmates and brings international collaboration to the mission. He has spoken about the pride Canadians feel and the scientific observations the crew will conduct during the lunar flyby.

6. Mission Focus: Testing Orion for Human Deep-Space Travel

Artemis II is primarily a test flight. The crew will not land on the Moon but will travel approximately 685,000 miles (about 1.1 million kilometers) on a trajectory that uses the Moon's gravity to sling them back toward Earth. They will evaluate Orion's life support, navigation, communication and re-entry systems in the harsh environment of deep space. Data collected will inform Artemis III and subsequent landings.

7. Launch and Timeline Details

The mission is targeted for liftoff no earlier than April 1, 2026, from Launch Complex 39B at Kennedy Space Center aboard the massive Space Launch System rocket. Daily two-hour launch windows are available through early April, with backup opportunities later in the month. The roughly 10-day flight will include a close lunar flyby, during which the astronauts will photograph the surface, observe geological features and conduct science activities from a unique vantage point.

8. Life Aboard Orion: Tight Quarters and Daily Routine

The four astronauts will live inside the Orion spacecraft, which has a habitable volume roughly the size of a minivan. They will sleep in bags attached to the walls, eat a menu that includes Canadian food items selected by the crew, and follow a structured schedule averaging eight hours of sleep. The first 26 hours after launch will be especially busy as they establish orbit, check systems and begin the journey toward the Moon. Laser communications will be tested for the first time on a crewed deep-space mission.

9. Extensive Training and Backup Support

The crew has trained together since their announcement in 2023, mastering every aspect of the mission, including emergency procedures and spacesuit operations that could sustain them for up to 144 hours in a loss-of-cabin-pressure scenario. Backup astronauts Andre Douglas and Jenni Gibbons accompanied the prime crew during recent activities and stand ready to step in if needed. The team entered quarantine in mid-March to protect health ahead of launch.

10. Broader Significance for Artemis Program and Beyond

Artemis II represents the first crewed step in NASA's plan to establish a sustained lunar presence and eventually send humans to Mars. The mission builds on the uncrewed Artemis I success and will demonstrate that Orion can safely carry humans far from Earth. International partners, including Canada, play key roles through the Artemis Accords. The crew's journey will also inspire global audiences, sending a message of unity and progress in space exploration more than five decades after Apollo 17.

As the astronauts complete final preparations at Kennedy Space Center, excitement continues to build. NASA plans extensive live coverage of launch and mission events. The crew has expressed gratitude for the opportunity and confidence in the teams supporting them on the ground.

Wiseman, Glover, Koch and Hansen embody the next chapter of human spaceflight — one defined by diversity, rigorous testing and ambitious goals. Their successful flight around the Moon would mark a historic return to deep space and set the stage for astronauts to once again walk on the lunar surface later this decade.

With launch opportunities opening soon, the world will watch as these four astronauts embark on a journey that stretches the boundaries of exploration and brings humanity one step closer to a multi-planetary future.
