You won't want to miss this Twitter Spaces event tomorrow! Legendary Apollo Flight Director Gerry Griffin and our own NASA Historian Jennifer Ross-Nazzal will be part of the conversation.
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). https://t.co/rO5HBPx0Ec
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. https://t.co/B5x3fSQQ74
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.

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 📷➡️https://t.co/RgnwqO6B7J
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.
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.
