Re: [amsat-bb] Re : Taking a picture of AO40 in orbit?

I recently saw a poster of the shuttle taken from a German satellite in
1985.  The photograph is aboslutely superb and in sharp focus with the
shuttle in a vertical position, loading bay doors open and the blue earth
making an arc in the left of the image.

I have often thought how valuable a photo of a broken satellite could be.
But judging from the size of the shuttle in the poster, not much detail
would be visible in a similar satellite-to-satellite photograph.

| Hi Dave,
|

|

which due

resolution could
| not be put into service for highly detailed satellite imaging.
|
| As you say, I've no doubt the military do have such an instrument and
probably
| could image AO-40, but to what resolution is anyone's guess?  Not the sort
of
| info that would be available on the public domain hi :-)
|
| A better choice would be a satellite that can image other satellites, but
not
| sure if there is such a thing? There's plenty of stuff flying around up
there
| that none of us are aware of, so I wouldn't be surprised if such a device
| does exist!
