A huge unmanned rocket carrying a secret new spy satellite for the United States roared into space Sunday (Nov. 21) to deliver what one reconnaissance official has touted as "the largest satellite in the world" into orbit. ?

The giant booster ? a Delta 4 Heavy rocket ? blasted off at 5:58 p.m. EST (2258 GMT) from the Cape Canaveral Air Force Base in Florida carrying a classified payload for the U.S. National Reconnaissance Office. [Photo of the spy satellite's dazzling night launch]

"This mission helps to ensure that vital NRO resources will continue to bolster our national defense," said Air Force Brig. Gen. Ed Wilson, commander 45th Space Wing, after the successful launch.

The satellite, called NROL-32, launched after a series of delays from technical glitches. The most recent glitch, a pair of faulty temperature sensors, thwarted a Nov. 19 launch attempt.

The exact purpose of the new spy satellite NROL-32 is secret, but one NRO official has hinted at the huge size of the reconnaissance spacecraft.

In a Sept. 13 address at the Air Force Association's Air and Space Conference, NRO director Bruce Carlson, a retired Air Force general, told an audience that this Delta 4 Heavy rocket would launch "with the largest satellite in the world on it."

For comparison, in July 2009 a satellite called TerreStar-1 ? touted as the world's largest commercial satellite ever built ? launched into space atop an Ariane 5 rocket. TerreStar-1 is 15,233 pounds (6,910 kg) satellite equipped with a huge 60-foot (18-meter) antenna. Last week, the SkyTerra-1 mobile communications satellite launched with its own giant antenna, one that is about 72 feet (nearly 22 meters) across.

The Delta 4 Heavy rocket is the United States' biggest unmanned rocket currently in service and has 2 millions pounds of thrust, making it the most powerful liquid fueled booster available today. A Delta 4 Heavy rocket stands 235 feet (72 meters) tall and is actually made up of three boosters, each called a Common Booster Core, arranged in a line to give it a three-column appearance.

The rocket is built and launched by the United Launch Alliance, a partnership between Lockheed Martin and Boeing. It made its first flight in 2004 and is capable of launching payloads of up to 24 tons into low-Earth orbit and 11 tons toward the geosynchronous orbits used by communications satellites.

Tonight's launch marked the fourth launch of a Delta 4 Heavy rocket and the second satellite launch in three months for the NRO. An Atlas 5 rocket launched the NROL-41 reconnaissance satellite on Sept. 20.

In his address last month, Carlson said that the current plan for NRO satellite missions ?"is the most aggressive launch campaign that the National Reconnaissance Office has had in 20 years, almost a quarter of a century."

Carlson went on to say that new satellites are vital for the NRO's mission, and are needed to replace older satellites before they fail.

"The other thing I can tell you is these are very important, because they all go to update a constellation which is aging rapidly," Carlson said last month according to an NRO transcript. "We bought most of our satellites for three, five, or eight years, and we're keeping them on orbit for ten, twelve, and up to twenty years."

"Now when I buy something people complain about how expensive it is, but nobody ever complains when it's time to die and it keeps right on ticking," Carlson added. "Some of these guys are like the Energizer bunny and they have really done marvelous work."

Nos hit, this has been on like every website today.

They tested this last week in California, yo!

It left a contrail 30 miles of the coast of California a few weeks ago....

Wrong coast dudes! The launch was in FL the contrail (which was prolly an IBM from a Jin class Chinese sub) was off the Pac coast...

.... as a UPS plane was launching it.

Somebody's gotta keep an eye on us when TSA doesn't have their hands in our pants.

Geez, I gotta remember that green font more often...

U mean that Obama is on that flight...to see and explore new worlds as the ambassador of peace from earth.

I happened to catch the launchcast of this in real time it went up on Sunday evening. Here is a link for the highlights: :::: United launch Alliance, LLC :::: The term heavy used to describe the vehicle seems very appropriate. I am surprised that they put out so many details about these launches. The article at the beginning of the thread is quoting Carlson hinting at numbers and lives of the systems.

Can you say, weapon?

BTW, that is a very efficient rocket, about 3% of it's lift-off weight is the actual payload. Most of the actual lift-off weight is fuel.
The saturn 5 rocket used in the apollo missions was prolly around 1.5% payload efficient.

It takes a whole bunch of that hot burny-stuff to put something in orbit.
