NOCTILUCENT ROCKET EXHAUST
On Sept. 2nd, an Atlas V rocket blasted off from Cape Canaveral carrying a Navy communications satellite to orbit. The dawn launch was much anticipated by local sky watchers. Waking up early turned out to be a good decision. "What see saw blew our, and everyone's, minds," reports Jack Jewell, who took these pictures from a grassy hill near the NASA causeway.



"I've seen enough launches just before sunrise to know that sunlit rocket plumes against a darkish sky can be magical," says Jewell. "This was one of the best."

The Atlas V created a man-made noctilucent cloud. Water vapor in the rocket's exhaust crystallized in the high atmosphere, creating an icy cloud that turned blue when it was hit by the rays of the morning sun. Years ago, space shuttle launches produced similar displays.

Natural noctilucent clouds form around Earth's poles when water vapor in the mesosphere crystalizes around meteor smoke. Sometimes they spread as far south as Colorado and Utah, but rarely or never Florida. Electric-blue over the Sunshine State requires a rocket launch.
