CAPE CANAVERAL, FL – History was made Wednesday morning as NASA’s Artemis I moon mission blasted off from Kennedy Space Center. This was the program’s third launch attempt after the mission director scrubbed the first two launches due to fuel leaks. Artemis I is an uncrewed test mission for the program that will ultimately return humankind back to the moon and later onto Mars. Follow our real-time updates with the countdown to liftoff.
