U.S. Withholding Satellite Data
plover writes "Because of Congressional legislation passed quietly in 2003, the Air Force Space Command will no longer distribute space surveillance data via NASA. There was supposed a three year transitional period where the data was to be made available via a NASA web site, but earlier this month their transitional server went down hard, and NASA has decided to not rebuild it. (It was scheduled to be shut down on 31 March 2005 anyway.) The only way to obtain satellite data now is by signing up with the official Space-Track website. Part of the agreement to obtaining data from their site is that you agree to not redistribute their data. Of course, amateurs are still free to redistribute their observations, including those of classified satellites."
What reasons are cited for this development? Security?
A blog like any other.
Why isn't there some sort of community political watchdog site that informs us when things are "quietly passed"? Tell us about everything that's in the works, let us decide what we do and don't like.
How hard is it to build a spy/telescope satellite ?
I found this site about building a miniature

I think it would be cool if someone could put a cheap one in space from off the shelf telescope parts . Don't you think these prices for these orbitting telescopes are a bit farfetched ?

,are not likely to care about breaking a contract.
Am i the only one thinking that people likely to abuse this information
The only things certain in war are Propaganda and Death. You can never be sure which is which though
The data is still free.
Its the projections of the sattelites that are secret and should be. Why should we all care?
A powerfull land based laser could take out a satelite and a trajectory is needed.
Weather and other services are still available.

So I was reading through the "terms of use" and got to this line "... By continuing, you consent to your keystrokes and data content being monitored." The way it's stated is so ambiguous that it's scarry. Anyone else agree?
No. Hubble regularly looks at Earth for calibration purposes. See: http://www.stsci.edu/stsci/meetings/shst2/williams r.html
They made one exception to look at the moon once, but I believe they had to do some tricky things to manage that.

I didn't know about the Hubble Moon pictures, nice one! Found them here: http://hubblesite.org/newscenter/newsdesk/archive
I had always understood that Hubble itself was a derivative of the Keyhole KH-11 spy satellites - i.e. the satellite bus and basic telescope were an existing design (that's why it was so cheap...). The sensors would of course be quite different; Earth Observation satellites are more like scanners than cameras. Google KH-11 for more info., but don't blame me when your garden fills up with black helicopters.
Science fiction for grown-ups...
The Keyhole series of satellites are similar to Hubble. The KH-12 has "a resolution approaching ten centimeters".
Hubble cost something like $2B (?). Spy satellites like the Keyhole 12 are similar to Hubble, and would cost at least that much. This gives you 10-cm resolution.
Sure, you could buy a simple telescope, duct tape a digital camera and a packet radio transmitter to it, and blast it into space.
But building optics that won't break during launch, and can handle the temperature changes is another matter. Building an attitude control system (a cluster of miniature rocket engines, plus control system) is nontrivial, too. You'll need energy (solar panels, fuel tanks), also built to last in space.
Off-the-shelf? No chance.
