A pair of Air Force surveillance satellites headed to geosynchronous orbit today to reconnoiter the high ground, departing Cape Canaveral aboard a United Launch Alliance Delta 4 rocket at 12:52 a.m. EDT (0452 GMT). It is the 375th Delta rocket flight since 1960.

India’s all-new GSLV Mk. 3 launcher blasted off for the first time at 0400 GMT Thursday (11 p.m. EST Wednesday) on a suborbital test flight to demonstrate a new twin-engine core stage, two powerful solid rocket boosters and a prototype capsule designed for India’s planned human space program.
