NASA has started a two-day wet dress rehearsal for its Artemis 1 mega moon rocket, the US space agency officials said. The dress rehearsal will demonstrate the team's ability to load more than 700,000 gallons of cryogenic, or super-cold, propellants into the rocket at the launch pad, practice every phase of the launch countdown, and drain propellants to demonstrate safely standing down on a launch attempt.
