The uncrewed Artemis I will launch on a mission that goes beyond the moon and returns to Earth. The rocket stack arrived at the launchpad on August 17 after a 4-mile (6.4-kilometer) ride aboard one of the Apollo-era giant NASA crawlers from the Vehicle Assembly Building - just like the shuttle missions and Apollo Saturn V rockets once did. This test will occur during a “quiescent point” ahead of the final countdown, said Charlie Blackwell-Thompson, Artemis I launch director at Kennedy Space Center. The hydrogen kick start, used to thermally condition the engines, did not occur during the final wet dress rehearsal, so this process is now a component of the launch countdown. There remains an open item the team will test on launch day, said Mike Sarafin, NASA’s Artemis mission manager. Very little remains on the task list after previous testing rounds of the rocket on the launchpad during wet dress rehearsal, which simulated every step of launch without lifting off. The “go” following the flight readiness review is a positive sign that things are on track for the mission, but there are still factors over the next week that could impact when it lifts off the pad, including bad weather.
There are backup launch windows on September 2 and September 5. The Artemis team is targeting its first two-hour launch window from 8:33 a.m. The review was an in-depth assessment of the preparedness of the 322-foot-tall (98-meter-tall) stack, consisting of the Space Launch System rocket and Orion spacecraft, currently sitting on the launchpad at NASA’s Kennedy Space Center in Florida.
That’s the result of NASA’s Flight Readiness Review, which was conducted on Monday. (CNN) - The Artemis I mission is ready to launch.
