NASA has posted the following predicted post-separation burn element set for STS-88 (from their web page: http://spaceflight.nasa.gov./realdata/elements/index.html ): STS-88 1 25549U 98069A 98347.90427233 .00088917 00000-0 14277-3 0 9210 2 25549 51.5950 48.6888 0009919 253.7217 106.2846 15.58056628 1519 This, obviously, presumes an on-time, nominal burn at 4:29PM EST (21:29 GNT), Sunday. I also noticed from their TV schedule -- http://spaceflight.nasa.gov./realdata/nasatv/schedule.html -- there is only one such burn prior to de-orbit, however there will be an RCS hot fire on Monday. I have no idea if or how that will impact any predicted viewing opportunity times, but I would hope not much. By the way, I hope some of you got to see the Mars Climate Observer launch footage. All I can say is "WOW." For those who may have missed it, they had a camera mounted to the exterior of the first stage and showed it from that vantage point, just after lift off, all the way through the booster jetison and second stage separation some hundred-plus miles up, clear and smooth the whole way.
