Artemis II will be the first crewed mission of the Artemis program, a complex and dynamic flight designed to thoroughly test Orion's life support systems with astronauts aboard. The mission will last approximately 10 days, following a free-return trajectory around the Moon. After launch from Kennedy Space Center's Launch Complex 39B, the SLS rocket will propel Orion into Earth orbit. Following a series of orbital maneuvers, the Interim Cryogenic Propulsion Stage (ICPS) will perform a Trans-Lunar Injection (TLI) burn, sending Orion on its path toward the Moon. The spacecraft will then perform a lunar flyby, passing within approximately 6,400 miles (10,300 kilometers) of the Moon's surface before using the Moon's gravity to slingshot back towards Earth. This free-return trajectory is a safety measure, allowing the spacecraft to return to Earth even if its engines fail after the TLI burn. The primary objectives are to validate Orion's critical systems, including life support, propulsion, communications, and navigation, with human operators, and to confirm crew procedures for deep-space missions. Secondary objectives include detailed radiation monitoring and testing of specific crew interfaces.
The Orion Spacecraft: Deep-Space Explorer
The Orion spacecraft is central to the Artemis missions, designed for long-duration deep-space travel.
