The Exploration Upper Stage is currently planned to fly as part of the Artemis 4 mission in September 2028. When will it fly?

All options are on or before the date/time listed, local time at the launch site. Resolves on launch of the carrier rocket; success of the launch or the stage itself is not required. All options resolve No if the EUS program is cancelled. Use in the Artemis 4 mission is not required; if it's replaced with something else on that mission and then flies on some other launch, options resolve according to when it flies.

I'll add more options as we get closer to launch and it becomes evident what's useful.
