With a series of practice countdowns complete, NASA managers said Friday the powerful Space Launch System rocket could be ready for its first test flight in late August or early September to send an unpiloted Orion crew capsule around the moon.

NASA officials said the fourth practice countdown for the SLS moon rocket Monday achieved enough objectives to declare the rehearsals complete, allowing teams to proceed with launch preparations for the Artemis 1 test flight, the first mission of the agency’s Artemis lunar program.

“At this point, we’ve determined that we successfully completed the evaluations and the work that we intended to complete for the dress rehearsal,” said Tom Whitmeyer, NASA’s associate administrator for exploration systems development, who oversees the SLS moon rocket and Orion crew capsule programs.

The 322-foot-tall (98-meter) Space Launch System rocket will roll off its launch pad at the Kennedy Space Center in Florida as soon as July 1, heading back to the Vehicle Assembly Building for a hydrogen leak repair and several previously planned tasks to ready the rocket for flight, according to Cliff Lanham, the senior vehicle operations manager for NASA’s exploration ground systems team in Florida.
