One day after the first launch of NASA’s heavy-lift Space Launch System rocket had to be scrubbed due to an engine cool-down issue, mission managers announced that they’d try again on Sept. 3. In the meantime, engineers will work out the details of a go/no-go plan, just in case they face issues similar to those that forced this week’s scrub.
Sept. 3’s two-hour launch opportunity opens at 2:17 p.m. ET (11:17 a.m. PT) at NASA’s Kennedy Space Center in Florida. If all systems are go, liftoff would mark the beginning of NASA’s Artemis 1 mission, an uncrewed test flight aimed at setting the stage for sending astronauts to the lunar surface in the mid-2020s.
