And that wasn’t the primary time an Artemis rocket had been despatched again to the store. The Artemis I SLS rocket went back to the Vehicle Assembly Building greater than as soon as in 2022, earlier than ultimately taking off and finishing its uncrewed check flight across the moon later that yr. The cumulative delays led NASA to announce a major overhaul of the Artemis program with the company now aiming for annual launches, doubtlessly dropping SpaceX and Boeing from its mission plans, and concentrating on two lunar landings in 2028.
As soon as Artemis II reaches the launchpad, NASA will conduct one other moist gown rehearsal and a flight readiness assessment earlier than it publicizes a launch window.
