Step by step, mile by mile 🌙 In this image, the mobile launcher for the #Artemis I mission arrives at the Vehicle Assembly Building (VAB) at NASAKennedy Space Center in Florida on Oct. 30, 2020. Engineers are conducting final integrated tests of the Orion spacecraft, the Space Launch System (SLS) rocket, and ground equipment, prior to rolling the rocket and spacecraft to the launch pad for a final test. This final test, known as the wet dress rehearsal, will run the rocket and launch team through operations to load propellant into the fuel tanks and conduct a full launch countdown. Following a successful rehearsal, NASA will roll the stack back into the VAB for final checks and set a target date for launch.
