We are capable! We are going back to the Moon with the Space Launch System rocket and @NASA_Orion spacecraft ready to travel further and explore more of deep space than ever before. As one of Artemis' arrows, #Artemis I will begin the new era of human space exploration.
Due to weather, @NASAGroundSys teams plan for the first motion of SLS and @NASA_Orion to take place at 11:00 pm EDT. The #Artemis I stack will roll back to the VAB at @NASAKennedy to address a liquid hydrogen leak and prepare the rocket and spacecraft for launch.
The #Artemis Generation is full of bright stars! 🤩 @girlscoutss recently hosted an essay contest asking girls to imagine their role in space exploration for the opportunity to earn a badge flown on@NASAArtemiss. Read more:nasa.gov/feature/nasa-a…nE
