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 Air Force will launch a second pair of small security probes 22,300 miles above the Earth using a Delta 4 rocket on Friday to alert ground controllers of impending space collisions and monitor potential meddling with U.S. orbiting assets.
Follow the unclassified portion of the Delta 4 rocket’s ascent to space from Cape Canaveral’s Complex 37 launch pad with the U.S. Air Force’s two Geosynchronous Space Situational Awareness Program, or GSSAP, satellites.
The two Geosynchronous Space Situational Awareness Program, or GSSAP, satellites for the U.S. military are mounted aboard the United Launch Alliance Delta 4 rocket. Liftoff is planned for Aug. 19 from Cape Canaveral.
A United Launch Alliance Delta 4 rocket went through a practice countdown and fueling exercise this week to prepare for its Aug. 19 liftoff to deliver a pair of orbital surveillance satellites into space.
Just three weeks after the Delta 4-Heavy rocket left the launch pad on its way to a successful satellite-deployment mission for U.S. national security, a smaller booster in the family has rolled out for its August military flight.
Some of America’s most critical surveillance satellites, final members of other spacecraft series and a probe that will touch an asteroid are among 15 rocket flights planned by United Launch Alliance in 2016.
