The Ares I-X flight test vehicle is poised on Kennedy Space Center's Launch Pad 39B and is ready to fly. The launch team reports no issues with the 327-foot rocket, the world's largest at present.
The only spoiler when tomorrow morning's launch window opens at 8 a.m. EDT might be the weather. Currently, there only is a 40 percent chance of favorable weather during the window, which extends until noon.
The team will have the same four-hour window for a launch attempt on Wednesday if Tuesday's liftoff is scrubbed, and Wednesday's weather shows a slight improvement to 60 percent "go."
The launch team of approximately 30 members will have their "call to stations" at 12:30 a.m., leading into the beginning of the seven-hour countdown at 1 a.m.
NASA's Launch Blog of the Ares I-X launch begins tomorrow at 5 a.m. EDT.
