NASA's Artemis II will send four astronauts to circle the moon without landing on it. The mission will set the stage for a human moon landing in 2028.

NASA officials said Sunday that the crew, Space Launch System rocket and Orion capsule are ready to launch the Artemis II mission to circle the moon.

From a race with China to lunar discoveries, the US is investing time, effort and money to head to the Moon - and beyond.
