NASA will fuel up its huge Artemis 2 moon rocket today (Feb. 2), and you can watch the crucial prelaunch test live.

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 fueling phase of prelaunch testing known as a "wet dress rehearsal" was delayed because of freezing temperatures at the launch pad located at NASA's Kennedy Space Center in Florida.
