NASA's Artemis II mission reached a critical milestone this week as teams conducted a wet dress rehearsal of the Space Launch System rocket and Orion spacecraft during an unusually intense blast of cold air surged across Florida, delivering record-breaking low temperatures to the Sunshine State.

However, NASA has not yet chosen an official launch date, and will not do so until the Artemis II stack passes its Wet Dress Rehearsal, with a simulated T0 that had been set for Saturday, Jan. 31 at 9:00 PM EST (02:00 UTC) but is now delayed until Monday, Feb. 2 at 9:00 PM EST (02:00 UTC Tuesday Feb. 3).

If the countdown and fueling test go well, four astronauts will set their sights on a Super Bowl Sunday launch to the moon.
