Just recently the United States of America launched its biggest satellite ever into orbit. The exact purpose for doing such launch is a top-secret, but there were some speculations that it has to do something with gathering some important information for the U.S. National Reconnaissance Office.
The satellite was known as the NROL-32 and it was sent into orbit through a Delta 4 Heavy rocket. Delta 4 is apparently the largest unmanned rocket that has the most powerful liquid-fueled booster. This rocket has a height of around 235 feet and made up of three boosters which are arranged in a line to give it some sort of three-column appearance. The Delta 4 was built and launched by the United States Alliance, which is partnership between Lockheed Martin and Boeing.
The NROL-32 was sent into space around 5:58 pm of November 21, 2010 from the Cape Canaveral Air Force Base in Florida after a series of delays due to some technical reasons. NRO Director Bruce Carlson has confirmed a month ago that NRO is planning some satellite launch and apparently said that it would be the most aggressive of all in the past 20 years. Carlson further states that these satellite missions are very important for NRO and very much needed in order to replace those satellites that are very useful in their intelligence missions in the past that are expiring soon.
Well, it seems that the United States of America is making some important moves that are associated with the improvement of the countries national defense. If you can remember they have also launched the TerreStar-1 rocket back in July 2009, which is the largest commercial satellite ever launched in space. The launch of the NROL-32 satellite is apparently the fourth launch of the Delta 4 rocket and also the second satellite launch made by NRO within the three months, the first being the NROL-41 reconnaissance satellite which was launched last September 20 via an Atlas 5 rocket.
Whatever the exact mission of NRO in launching the NROL 32 is, the fact still remains that this step made by the NRO will definitely be an important part of the history.
