Bad weather has forced NASA to delay today's launch of two new lunar probes that are designed to make detailed studies of the inside of the moon and its gravitational field. Windy conditions thwarted two available launch opportunities this morning (Sept. 8), so the agency will have to wait until tomorrow to try again.
NASA's twin Grail spacecraft were scheduled to blast off on an unmanned Delta 2 rocket at 8:37 a.m. EDT (1237 GMT) this morning from the Cape Canaveral Air Force Station in Florida, but upper-level winds in the area caused the agency to stand down.
