NASA’s rehearsal for Artemis II marks one of the final steps before four astronauts get launched into deep space for the first time since the Apollo program ended.

NASA is just days away from its first chance to launch Artemis 2, the first astronaut mission to the moon since 1972, and will attempt a critical test for the lunar flight on Monday, Feb. 2.

The Artemis 2 launch is aiming to send four other astronauts around the moon and back to Earth.
