Atlas 5 successfully launches U.S. surveillance satellite

Atlas 5

The competition heats up: A ULA Atlas 5 rocket today successfully launched a National Reconnaissance Office (NRO) surveillance satellite, dubbed NROL-61.

NROL-61, however, launched atop an Atlas V 421 rocket, a configuration that has not previously been used by the NRO. The spacecraft itself was encapsulated within an Extra-Extended Payload Fairing (XEPF) – at 14 metres (46 feet) in length the longest of three available four-metre (13-foot) diameter fairings – which has also never before been used for an NRO mission.

…The most likely explanation is that NROL-61 will be the first in a new generation of Quasar satellite; which would appear to be larger in both size and mass than its predecessors. Quasar, also known as the Satellite Data System, or SDS, is a constellation of communications satellites operated by the NRO to support its other intelligence-gathering activities; relaying data from other satellites to the ground in real-time, without having to wait for the intelligence-gathering satellites to pass over ground stations on friendly territory. If NROL-61 represents a new version of Quasar, it will be the fourth generation of the constellation.

NASA has decided that the best use for two space mirrors donated to the space agency by the National Reconnaissance Office (NRO) would be to study either dark energy and extrasolar planets.

There is no funding as yet for either mission, so for the moment the mirrors will remain on the ground, in storage.
