    Hi all,

    Question: how does the space shuttle roll right cater it launches? If you watch the takeoff it rolls shortly after take off, I think resulting in the shuttle exiting tht atmosphere upside down. So how does it initiate that first roll? Is it a function if the wings (ailerons?) Also why does it enter upside down? :) My guess is that for visibility its better to see the earth and allow for communications than being bottom to earth, but why not flip once in orbit?

    Probably.

    Nothing to see.

    And perhaps the solid bottom protects it better from space dust and solar radiation?

    It's tough to tell by video.



    Go to 6:20. There doesn't appear to be any movement of its flight controls on the wings. The SSME's( since they are gimbaled) probably cause the roll.

    As to why it rolls, I am not 100% sure either. But, it does flip back over to jettison the ET and stays that way until it does the pitch maneuver to have the ISS crew examine the tiles.

    Shouldn't this all be past tense, since we're never going to see it again. "How did the space shuttle roll on launch." :( :mad: ;)

    There is one more launch, but any rolling action will be done by the SCA enroute to LA. ;) :p
