The launch of five space science satellites on a Delta 2 has been pushed back a day when stormy weather hindered launch preparations. The Delta 2 carrying the five THEMIS satellites was scheduled to launch Thursday afternoon from Cape Canaveral, but fueling operations on Tuesday were postponed by thunderstorms in the vicinity of the launch site. The launch has been rescheduled for 6:05 pm EST (2305 GMT) Friday. The THEMIS (Time History of Events and Macroscale Interactions during Substorms) satellites will be used to study the development of large energy releases called "substorms" in the Earth's magnetosphere.
