NASA's Artemis II mission is launching the first humans back to the Moon in over 50 years. A crew of four astronauts is on a 10-day mission around the Moon and back, kicking off the first crewed mission of the agency's Artemis program, which aims to land people on the Moon in 2028 and eventually set up a base there.
Artemis II is a test flight, meaning that its primary objective is to demonstrate key systems that would be needed for a crewed mission to land on the Moon. That include Artemis II's launch vehicle, the Space Launch System (SLS) rocket, and its crew capsule, Orion.
The mission is expected to take about 10 days to complete. The mission launched from NASA’s Kennedy Space Center in Florida on April 1, using Launch Complex 39B — the same historic pad used for Apollo and Space Shuttle missions. Orion will orbit Earth twice while the crew tests out its systems, then the mission will head for the Moon, eventually flying as close as 8,000 kilometers (5,000 miles) from its surface on April 6. After traveling back to Earth, the crew will reenter the atmosphere, descend under parachutes, and splash down in the Pacific Ocean on April 10.
