A permanent webcast of #ArtemisII has begun at https://www.youtube.com/watch?v=m3kR2KK8TEs and will first cover tanking and run all the way to splashdown (separate webcasts will cover special mission phases like lift-off). Also live updates will be published on the page https://www.nasa.gov/blogs/missions/2026/04/01/live-artemis-ii-launch-day-updates/ just set up.

Since this one will certainly be archived (not sure about the permanent webcast), https://www.youtube.com/watch?v=Tf_UjBMIzNo is the NASA webcast specifically for the #ArtemisII launch. The crew is already in the capsule - this had been their walk-out: https://www.facebook.com/watch/?v=2086875691887758 and https://www.facebook.com/scott.schilke.1/posts/pfbid0261UbknbRbYWXenoR8DgC3GcDDH4RRL6FDgoW13vycnXUz4Tq5oz1yXLbzcYuPjMjl

What a chaotic launch broadcast for an historic mission ... here is the only lift-off full view, visible merely for a brief fraction of a second. Anyway, Orion and ESM are in Earth orbit now!
The best view from the botched #ArtemisII NASA launch webcast: the separation of the Interim Cryogenic Propulsion Stage (with the Orion, not visible) from the Core Stage, seen from the Launch Vehicle Stage Adapter - scroll down on https://skyweek.wordpress.com/2026/04/01/artemis-ii-vor-dem-start-maps-vor-dem-perihel/ for a sequence of nine screenshots from the whole ascent.
@cosmos4u That was a "WOW!" shot we loved for all two seconds we got to see it. 😂
@croyle In the weeks (!) after the launch of Artemis I we got to see more and more great video material from all kinds of angles - hoping for (much) more this time, too.
