April 1, 2026 — NASA is preparing for Artemis II, humanity’s first crewed journey beyond low Earth orbit in over 50 years, as four astronauts gear up for a historic flyby of the Moon that will pave the way for future lunar landings.
Return to Deep Space
The Artemis II mission represents a critical milestone in NASA’s ambitious plan to return humans to the Moon and establish a sustainable lunar presence. Unlike the uncrewed Artemis I test flight, Artemis II will carry four astronauts on a journey around the Moon, testing all the systems needed for future surface missions.
The crew will travel aboard the Orion spacecraft, launched by NASA’s powerful Space Launch System (SLS) rocket from Kennedy Space Center in Florida. The mission is currently targeted for late 2025 or early 2026, pending final systems verification and crew training completion.
Historic Crew
NASA announced a diverse crew that reflects the agency’s commitment to inclusion in space exploration. The mission will include the first woman and first person of color to travel to the Moon, marking a significant departure from the all-white, all-male Apollo crews of the 1960s and 70s.
The four astronauts have been training intensively for over a year, practicing emergency procedures, conducting simulations, and familiarizing themselves with Orion’s advanced systems. Their approximately 10-day journey will take them farther from Earth than any human has traveled since Apollo 17 in 1972.
Mission Profile
Artemis II will follow a figure-eight trajectory around the Moon, coming within roughly 6,500 miles of the lunar surface. This path allows the crew to use the Moon’s gravity to slingshot back toward Earth without requiring a lunar orbit insertion—a critical test of navigation and life support systems.
During the mission, astronauts will validate Orion’s environmental control and life support systems, test communications equipment, and perform manual flying exercises. They’ll also capture high-resolution imagery of the lunar surface to assist in landing site selection for future missions.
Technical Challenges
The mission faces several technical hurdles. Engineers are working to resolve heat shield concerns identified during Artemis I’s splashdown, where charring patterns differed from predictions. While not considered a safety threat, NASA is conducting additional testing to ensure crew safety during the fiery reentry at lunar return velocities.
Additionally, teams are addressing software updates for Orion’s guidance and navigation systems, and conducting final integration tests between the spacecraft and SLS rocket. The complexity of human-rating these systems for deep space has contributed to schedule adjustments.
Gateway to Artemis III
Success of Artemis II is essential for NASA’s timeline to land astronauts on the Moon’s south pole region with Artemis III, currently planned for 2026 or 2027. That mission will use SpaceX’s Starship lunar lander to transport crew from Orion to the surface and back.
The south pole holds particular scientific interest due to permanently shadowed craters that may contain water ice—a crucial resource for future lunar habitation and as a potential source of rocket fuel for deeper space exploration.
International Partnership
Artemis represents unprecedented international cooperation in space exploration. The program includes participation from the European Space Agency, which provides Orion’s service module, as well as the Canadian Space Agency, Japan Aerospace Exploration Agency, and others.
This collaborative approach aims to establish norms for peaceful space exploration and resource utilization as humanity expands beyond Earth orbit.
Scientific Goals
Beyond serving as a test flight, Artemis II will conduct several scientific experiments during its journey. Radiation monitoring equipment will measure the deep space radiation environment astronauts will encounter on longer missions, informing protective measures for future crews.
The mission will also test new technologies for space medicine, including advanced health monitoring systems that could prove vital for extended deep space missions to Mars and beyond.
