Artemis just updated:
NASA has requested backup launch opportunities for Wednesday, November 16, at 1:04 a.m. and Saturday, November 19, at 1:45 a.m., which are both two-hour launch windows. A launch on November 14 would result in a mission duration of about 25-and-a-half days with a splashdown in the Pacific Ocean Friday, December 9.
The Saturday early morning Artemis could give the 11/18 Getaway folks (me included) a double header launch with the Friday 5:30 Falcon for sail away and then the nightcap Artemis blastoff at sea!
