A wonderfull tool for those third-world nations that want to avoid recon sat passes.
They've been able to do that for a while, our advantage was until recently, other countries tended to underestimate the capabilities of those satellites, or our ability to piece together facts on the ground from the imagery.
we can also change the speed of those satellites so it wouldn't be accurate, if it even shows those. I will have to check, I want to see the soviet ones (names withheld) that pass over my local base (be nice to know when they cross).
As I understand it, changing the speed of the satellite uses fuel which reduces the operational liftime of the satellite, and is the sort of drastic move that is only done when there is reason to be especially suspicious, so it is normally accurate. Also from looking at that site, I have come to the conclusion that it may be nothing more than advertising. This is what came up for my area code.
BRIGHTNESS: visual magnitude 3 (dim but visible)
Genesis 1 is a prototype space hotel room -- no kidding! Genesis was launched by Bigelow Aerospace as a test to see if inflatable satellites can be orbited and eventually connected together to create a sprawling space hotel. There are currently two modules in orbit: Genesis 1 and Genesis 2. Both modules are faint, they shine like 4th magnitude stars, but they are easy to notice with the unaided eye because of their motion across the sky. For more information visit the Bigelow Aerospace web site. I just searched Washington DC, the same thing came up.
Apparrently according to their site, aside from Genesis, the only other things they track are Hubble and the ISS
