NASA teams have been given the “go” to proceed with fueling ahead of tonight’s Artemis I launch, a high-profile mission to the moon decades in the making.

Teams are expected to start fueling the 322-foot Space Launch System rocket with liquid hydrogen and oxygen at 3:50 p.m. EST, or just over nine hours before liftoff. NASA has a two-hour window, starting at 1:04 a.m. EST Wednesday, Nov. 16, to launch the rocket from pad 39B.

Weather for tonight’s attempt, according to the Space Force, stands at 80% “go.” Visit floridspantodspany.com/spspance starting at 9 p.m. EST to watch live video and updates from KSC.

So far, managers have had to contend with several scrubs and delays to this Artemis I mission. Some were caused by technical issues, while others were the results of hurricanes Ian and Nicole. Though two main hardware issues were found in the wake of Nicole, teams on Monday gave the go-ahead to proceed with launch operations.

After liftoff, the uncrewed Orion capsule stacked atop the SLS rocket will fly on a roughly month-long mission to lunar orbit and back. If it successfully returns to Earth, NASA hopes to put astronauts in the capsule and run a similar mission known as Artemis II sometime before 2025. Then, Artemis III would put two astronauts on the moon’s surface before 2030.
