Check out this slow motion shot of the four RS-25 engines and twin solid rocket boosters as they ignite and light up the night sky - lifting SLS off of Launch Pad 39B and sending @NASA_Orion toward the Moon!

LIVE NOW: The @NASA_Orion spacecraft is performing its first powered lunar flyby. Orion will make its closest approach to the lunar surface during the #Artemis I mission - approximately 80 miles – at 7:57am ET (12:57 UTC). x.com/i/broadcasts/1…

While #Artemis I is uncrewed, a manikin named "Commander Moonikin Campos" is among the test devices flying aboard @NASA_Orion. The name honors NASA engineer Arturo Campos, who helped bring the Apollo 13 crew safely home to Earth. nasa.gov/specials/mooni…

We are going! @NASA_SLS and @NASA_Orion lifted off from Pad 39B at 1:47 am EST for @NASA's #Artemis I mission to the Moon. Follow the mission HERE >> go.nasa.gov/3AjxKQQ

Trans-lunar injection burn complete! @NASA_Orion is on its way to the Moon! Thanks to ICPS, @NASA_SLS's upper stage, for the push to get us on our way.

LIFTOFF! @NASA_SLS and @NASA_Orion launch on their first flight, the #Artemis I mission. Keep checking back for more launch images 📷➡️flic.kr/s/aHBqjzG1pG

Music to my ears... . . . #GoArtemis #gosls #Artemis1 #NASA

What. A. Beautiful. Sight! . . . #artemis #arteis1 #goartemis #gosls #spacecoaat #spacecoastlife #rocketcity #nasa

All elements polled are 'go’ to proceed with the terminal count. Countdown clock is resuming at T-10 minutes. No constraints to launch.

We are now in replenish mode on upper stage for both liquid hydrogen and liquid oxygen. We remain in a hold.

Upper stage liquid hydrogen is now in 'topping'. The Range Safety Officer is testing the Flight Termination System (FTS). The launch team is determining our new launch time.

We are in our planned hold at T-10 minutes. Currently, the upper stage liquid hydrogen is 78% filled. Core stage has been topped off – both liquid hydrogen and liquid oxygen are 100% filled. The ethernet switch has been replaced and will be verified.

Hey! @rocketcenterusa is getting a little air time in NASA TV. Nice to see my old haunt, even if it is on a TV at KSC! . . . #artemis #NASA #spacecoast #spacecoastlife #goartemis #spacecoastliving #artemis1 #artemisi #rocketcity #kennedyspacecenter

It looks like this mission's target is sneaking a peek at it's new visitor! . . . #artemis1 #artemisi #artemis #goartemis #sls #gosls #orion #spacecoastlife #spacecoastliving #spacecoast #NASA

The 'red crew' team has successfully remedied the leak, and it has not recurred. Bad ethernet switch is being replaced now.

Upper stage is now in fast fill at 58% liquid hydrogen filled. Liquid oxygen for both upper and core stage are in stable replenish.

Range Safety Officer reported to NASA Test Director a problem with a bad ethernet switch and the Range is currently working to change it out and reverify it. Range reporting that it should take about 70 minutes to do that work.

Fastfill complete and back in core stage topping.
