Q&A with Steve Skladanek, president of Lockheed Martin Commercial Launch Services

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.

The rescheduled mission comes following the April 9 scrub due to poor weather and a period on the Eastern Range marked by a noted lack of orbital launches. Liftoff from pad 41 at Cape Canaveral Space Force Station is targeting Monday, April 28, at 7 p.m. EDT (2300 UTC).
