NASA's new megarocket for its Artemis 1 moon mission is on the launch pad for the first time. On Thursday March 17, with the largest doors in the world wide open at the Vehicle Assembly Building (VAB) at NASA's Kennedy Space Center here on Florida's Space Coast, the rocket that will launch the next astronauts to the moon began rolling out to the launch pad. It reached its destination more than 11 hours later. For its wet dress rehearsal for launch that will happen later this May. Artemis will be an uncrewed flight to the moon and back by the Orion spacecraft. Which will carry humans back to the moon in 2024.
