Endeavour's Final Launch Inspires Hands-on Public Engagement: High Altitude Balloon Mission
"The helium-filled balloon carrying the "Senatobia-1" payload will be launched from the vicinity of Gainesville, Florida. The expected balloon launch time is on Monday, 16 May between 7:30 to 7:45 am EDT. This will allow the balloon and its payload to be in position at an altitude of approximately 100,000 feet for Endeavour's supersonic transit of the stratosphere beginning with a planned liftoff at 8:56 am EDT. If there is a delay in the launch of Endeavour the Quest for Stars team is ready to try again - several times - on subsequent days."
Keith's note: If all goes according to plan we will have live video from the balloon as Senatobia-1 ascends to catch Endeavour. Video feeds and tracking links here. Launch site feed begins at 7:15 am EDT. This is the projected flight path.
