NASA's Moon Rocket Fuel Test: A Giant Leap or Slip?
31 Jan
Summary
- The "wet dress rehearsal" tests loading 700,000 gallons of propellants.
- Artemis II will carry three U.S. and one Canadian astronaut.
- Launch director emphasized lessons learned from Artemis I fueling issues.

NASA's Artemis II mission is nearing a pivotal "wet dress rehearsal," scheduled for Monday, February 2nd. This crucial test will load the Space Launch System rocket with 700,000 gallons of ultra-cold propellants at Kennedy Space Center. The rehearsal simulates the entire countdown sequence, stopping just 29 seconds before potential liftoff.
The outcome of this fueling test is critical for setting the actual launch date for Artemis II. This mission represents NASA's first crewed flight to the moon in over five decades. Commander Reid Wiseman, pilot Victor Glover, Christina Koch, and Canadian astronaut Jeremy Hansen will embark on the 10-day journey aboard the Orion spacecraft, named Integrity.
NASA has implemented changes based on lessons learned from Artemis I, where fueling issues, including hydrogen leaks and temperature control problems, caused delays. Upgraded fuel pumping systems, improved ground equipment connections, and redesigned valves are expected to ensure a smoother process this time. Mission leaders are optimistic about success, citing previous challenges as valuable learning experiences.
