This is NASA's Ares I-X rocket — the unmanned version of the Ares V, which, at 380 ft high, will be the tallest rocket ever — on Launch Pad 39B at Cape Canaveral's Kennedy Space Center awaiting a delayed liftoff.

The flight test of Ares I-X, originally scheduled for sometime before noon today and now scrubbed, will eventually — when it takes off — provide NASA with an early opportunity to test and prove flight characteristics, hardware, facilities and ground operations associated with the Ares I.
