NASA's Artemis 2 Wet Dress Rehearsal
NASA is conducting a crucial second wet dress rehearsal for its Artemis 2 mission, a high-stakes fueling test designed to resolve persistent hydrogen leaks and other issues that plagued a previous attempt. This intensive 50-hour countdown, involving over 700,000 gallons of supercold propellants, is a vital step toward the first crewed lunar mission since Apollo 17 and will determine the feasibility of a March launch for the four astronauts.
