Artemis II Moon Rocket Refueled in Practice Countdown Setting Stage for Historic Flight
- On Feb 19, NASA ran a second wet dress rehearsal at Launch Complex 39B, filling the Space Launch System rocket and Orion spacecraft with propellant and reaching T-minus 29 seconds twice.
- After a Feb. 2 stop for a liquid hydrogen leak, technicians and engineers replaced seals and a ground support equipment filter, delaying the crewed launch to early March.
- Slow chilldown then fast fill loaded the core stage and upper stage with more than 700,000 gallons of liquid hydrogen chilled to minus 423 degrees Fahrenheit and liquid oxygen chilled to minus 297 degrees.
- Mission managers will now review rehearsal data and, if favorable, NASA says liftoff with the Artemis II four-person crew on a 10-day lunar flyby could come as early as March 6, 2026, with a news briefing at 11 a.m. ET on Friday.
