Update for 2 am ET: NASA successfully launched the Artemis 1 moon mission on the first Space Launch System rocket at 1:47 am EST (0647 GMT) in a stunning success. Read our full Artemis 1 launch story.
After enduring a battering by Hurricane Nicole, NASA's Space Launch System moon rocket is standing on a launch pad (again) ready for its debut flight. If you couldn't make it to the launch in person, you can at least be part of it with Space.com's Brett Tingley, who is very excited to see the huge rocket fly.
If all goes to plan, the Space Launch System (SLS) rocket will lift off from Launch Pad 39B at NASA's Kennedy Space Center in Florida at 1:04 a.m. EST (0604 GMT) on Wednesday (Nov. 16). You can watch the launch live on Space.com, courtesy of NASA, at 1:04 a.m. EST (0604 GMT) on Nov. 16.

The launch window will be open for two hours, however, so it could be a long night. If you are among the many space nerds who are staying up late for the liftoff, you can tune in to one of Brett Tingley's Space.com webcasts on YouTube or Facebook, where you can ask him questions about the milestone mission, known as Artemis 1.
The mission, the first in the NASA-led Artemis program, will test technologies for humankind's return to the moon. During the test flight, only two manikins, named Helga and Zohar, will occupy the Orion space capsule, which will be boosted by the SLS rocket for a lunar round trip. The capsule suffered some minor damage from Hurricane Nicole last week, but NASA engineers concluded the spacecraft was still fit for its mission.
Artemis 1 has already been postponed several times, because of technical glitches and the arrival of Hurricane Ian on Florida's Space Coast. NASA hopes to fly its successor, Artemis 2, which will take a human crew for a lunar round trip, within the next two years. The Artemis 2 mission will be the first to take humans into lunar orbit since the Apollo program. Ultimately, NASA plans not only to land humans on the moon again but to establish a permanent human station on its surface.
