Space Spotters Track Secret Satellites

Ponca City, We Love You writes "When government officials announced last month that a top-secret spy satellite would come falling out of the sky they said little about the satellite itself. They didn't need to. Spotters equipped with little more than a pair of binoculars, a stop watch and star charts, had already uncovered some of the deepest of the government's expensive secrets and shared them on the Internet. Thousands of people form the spotter community. Many look for historical relics of the early space age, working from publicly available orbital information. Still others are drawn to the secretive world of spy satellites, with about a dozen hobbyists doing most of the observing. When a new spy satellite is launched the hobbyists will collaborate on sightings around the world to determine its orbit, and even guess at its function. They often share their information on their web site, satobs.org."

    It is actually getting harder to identify satellites due to the efforts that certain governments are taking, including building in additional propulsion and stealth features built into the latest launches to alter and conceal orbits from those that might be predicted from launch. This is to prevent not only the ability to track orbits and know when a particular platform may be overhead, but it also prevents many of the current technologies like adaptive optics from being able to identify features of orbiting satellites as shown here .

      Of course people know where these satellites are. Between radar and simple telescopes, they are easy to see and compare to lists of known objects. One of the main reasons the Predator and other drones are effective at finding terrorists and the like out in the mountains or desert is because the terrorists know when our satellites are going overhead. They hide when the satellites goes over, and move when the sky is clear overhead, which is when we send out our drones.

This was so for example, in a time of crisis (the shuttle was designed during the Cold War after all), the Shuttle could be launched from Vandenberg AFB into a polar orbit, immediately drop a spy satellite into orbit on the first go around (to prevent an enemy from learning the projected orbital path of the spy satellite by tracking the shuttle through multiple orbits), and then come right back to land on the west coast. Of course the earth would have rotated eastwards during that 90 minute orbit, so the shuttle needed the crossrange to be able to also glide eastwards and make a landing. Some original designs showed the shuttle having straight wings; apparently one of the major reasons NASA went with a delta-wing configuration was to meet the crossrange requirement.

    The weight and expense to power ratio for plutonium or other decay based power systems is too high compared to solar arrays and batteries when in low earth orbit. The stuff that uses nukes is generally interplanetary in nature and cannot depend on solar. This is especially true with US launched stuff. Plus, nuclear power units have too high a heat signature to be used for "stealthy" sats, and are heavy and too expensive to launch if there is a cost-worthy alternative. Which there is: good ol' solar arrays, nice and thin.

    The intelligence agencies would much rather have more gizmos if given the choice. Solar arrays provide them with better weight tradeoffs, and more power as well -- meaning they can add more stuff and use more power hungry stuff. And they are cheaper to deploy, and less likely to run afoul of regulatory issues i.e. try dragging a nuc design for LOE (low earth orbit) in front of an Engineering Design Review board - they'll laugh you out of the room for being politically stupid.

    And if you are talking about the voiced concerns that the satellite in question (US-193, NROL-21) has hazardous material, well that hazmat is rocket fuel for orbital manuvering - the full load of it given that the sat never deployed the solar arrays, nor attemted to manuver to a more stable higher orbit.

I'm sure this is only one example of many recent satellites that have been painted black.Either way, painting a satellite would only solve a small amount of the problem, since pretty much all satellites carry an RF payload which transmits data back to earth, they can be detected this way if they cannot be seen. The article mentions the 'seesat' group which does visual obs, but a parallel group 'hearsat' works with the RF downlinks, identifying satellites purely by their RF fingerprints.
