Mighty Delta 4 Heavy rocket and clandestine satellite poised at pad

A mighty triple-barreled Delta 4 Heavy rocket with a clandestine military satellite perhaps the size of Hubble was unveiled this evening (June 28) at a seaside launch pad at Cape Canaveral, Florida.

The 232 foot tall rocket is poised to blast off at 6:13 a.m. EDT from Space Launch Complex 40 at Cape Canaveral Air Force Station. The exact launch window, like everything else about the classified mission and the NROL-15 spy satellite is top secret.

The mobile service tower was retracted from around the absolutely gorgeous white and orange colored rocket starting around 8:30 p.m. and the super secret spy satellite being launched for the National Reconnaissance Office (NRO) – see my photos.

The launch was delayed a day by the lingering devastation caused by Tropical Storm Debby.

The United Launch Alliance Delta 4 Heavy is flying for the first time with upgraded RS-68A first stage engines, each of which delivers 720,000 pounds of thrust.

This will be the 6th launch of the Delta 4 Heavy – now the most powerful rocket in the US fleet following the shutdown of NASA’s Space Shuttle Program.

As of 12:45 a.m. June 29 , the countdown is now underway! Fueling will commence shortly. Stay tuned for a post – launch report.
