NASA Mission Update

Managers from United Launch Alliance (ULA) and Lockheed Martin gave a “go” to proceed toward launch pending completion of open work during the Launch Readiness Review for Orion’s flight test. The weather is forecast to be 60 percent “go” for a scheduled liftoff at 7:05 a.m. EST on Thursday, Dec. 4.

NASA TV will air an Orion Flight Test Status and Overview briefing at 1 p.m. today. On Dec. 3, a prelaunch status briefing will be held at 11 a.m. A NASA overview event with participation from social media followers will air at 1 p.m.

Meteorologists have not changed their prediction for Thursday morning’s weather and they continue to call for a 60 percent chance of acceptable conditions for Orion’s lift off on its first flight test. The launch window opens at 7:05 a.m. EST and closes 2 hours, 39 minutes later at about 9:44 a.m. The concern remains early morning precipitation at or near the Florida spaceport. NASA reserved the Eastern Range for Friday and Saturday as well, in case Thursday’s launch opportunity is not made.

    Go Orion.
    While I am not a fan of SLS (or the waste of money on Orion), I have to say that at this point, I really want to see it go and perhaps be used.
    Even ESA could use it.

    It’s surprising how low key this is, the mainstream media barely seem to have noticed it. Within the aerospace media, there seems to be much more interest in someone else’s grid fins and barge than what is actually the first flight of a new spacecraft. I think the Ares I test flight got more attention, and that was barely more than a shuttle SRB with fake parts stuck on.

    At least now that I’m in the UK for the Winter, I’ll be able to watch this launch live during the daytime. Having a whole mission take place over a few hours does make it a bit of an event.

    Huh? Pretty much every space media site I visited is covering this, much much bigger coverage (and hype: we’re going to Mars, yeah!) than Elon’s little experiment.

    Good luck, Orion
