When Artemis I launches from Kennedy Space Center, it has a planned flight that will last weeks taking the Orion spacecraft to the moon and back on a trip that will travel more than 1.3 million miles before it splashes back down on Earth in the Pacific Ocean.

The first launch attempt on Monday, Aug. 29, 2022, was scrubbed, but now NASA is aiming for a Saturday, Sept. 3 attempt during a two-hour window that opens at 2:17 p.m. A backup opportunity exists on Monday, Sept. 5 during a 90-minute window that opens at 5:12 p.m.

The Orion capsule will launch atop the Space Launch System rocket from KSC’s Launch Pad 39-B. NASA will be making Orion’s location public through the Artemis Real-time Orbit Website (AROW).

Here’s a timeline for activities from launch to landing:

L-46 hours 40 minutes and counting

L-9 hours, 40 minutes and counting

6:45 a.m. Coverage begins with commentary of tanking operations to load propellant into the SLS rocket at NASA.gov/nasalive.

12:15 p.m. Full coverage begins in English. Launch coverage will continue through translunar injection and spacecraft separation, setting Orion on its path to the Moon at NASA.gov/nasalive.
