NASA managers say they have completed testing of the Space Launch System 🚀after a recent countdown rehearsal and are ready to move into preparations for a launch as soon as late August.
NASA plans to roll the mobile launch platform carrying SLS back to the Vehicle Assembly Building (VAB) early July 1, weather permitting. Once back in the VAB, crews will spend several weeks preparing the vehicle to return to the pad for the Artemis 1 launch.
NASA got most of the way through the test, known as a “wet dress rehearsal,” this week, fully fueling the Space Launch System rocket’s two stages with more than 700,000 gallons of liquid oxygen and liquid hydrogen. But the simulated countdown was cut short with 29 seconds to go because of a hydrogen leak.
