I offer a different opinion. We know how large the primary mirror
(optical aperture) of these spy satellites are, because we know how
big the launch vehicles are, and the satellites had to fit into the
launch vehicles. Therefore, I believe they are no larger than
Hubble. Therefore, I figure the spook agencies can't actually help us.
Someone earlier offered a calculation of the resolution Hubble could
achieve when imaging AO40, based on the aperture, and the minimum
possible distance, given the orbits of Hubble and AO40. The answer
was 5", which just isn't really good enough to see what may have happened.
Because the distances are large, and because we have no hope of any
telescope that's gonna fly up next to AO40 to take a close look
(unless we build & launch it ourselves!), all existing
single-aperture telescopes seem to be unable to do the job.
Seems to me that the only technique which could have a chance is
interferometry. At radio frequencies we're familiar with phased
array antennas where signals from multiple antennas are combined
coherently. Doing this at optical frequencies always seemed
impossibly difficult to me, so I figured I would never see it.
In recent years however those darn astronomers have started doing
optical interferometry. They've imaged the surface of stars,
measured the sizes of extrasolar planets, etc. Some of their images
appear to indicate sub-milli-arcsecond resolution.
Two of these instruments are CHARA and COAST.
CHARA...
http://www.chara.gsu.edu/CHARA/
See the two detailed documents on CHARA by clicking on the links
labelled "here and here" about half way down the page.
COAST...
http://www.mrao.cam.ac.uk/telescopes/coast/handout.html
I wonder if this sort of instrument could image a satellite?
There are of course a large number of practical engineering
considerations. These machines require bright objects. A satellite
in sunlight is pretty bright. Enough? Satellites require rapid
tracking. I doubt they designed these machines to do that. The
satellite is likely tumbling, so maybe you can't correlate or average
data taken over a few minutes or even seconds apart. I don't know
what exposure times would be required. Etc etc. I don't know the
answer to any of these questions, or even how to go about figuring
out the answers.
Having said all this, I suppose it is possible that the spooks have
done the engineering to make multiple optical satellites work
together as an optical interferometer, and therefore have the high
resolution capability that we need, but I am guessing that they have
not (yet). (Just look at all the work the ground-based astronomers
have done to make this work with a huge machine nailed down to the
ground. Just doesn't look ready for space yet!) And even if the
spooks had done this work, they wouldn't give it away (yet) by
showing us pictures.
So, back to the non-spook world, could a machine like CHARA or COAST
image a satellite?

Ditto. I have the single port version (model USA-19HS), and have used it
under both Linux and Windows XP (running inside VMWare on said Linux box, as
well as natively). Linux kernels were from SuSE/OpenSuSE 10.0 through 11.1.
No problems.

OK, great! I don't want to tie up the JOTA side of AO-51 with
those looking for grids or the AZ/NM state line (I think I can
park on it, just off I-10), but I will call you and say hello to your
group if you are on the .300 side.

That is not what I would call a success. It is indeed true that when something
goes wrong in space, we have to grin and bear it, turning lemons into
lemonade. etc. But to redefine what a success is, simply to put
a positive spin on a failure, is counterproductive. It seems to me that
the problems are acknowledged and are worked upon, makes more sense.
I do not see the arguments for "It was a success because of its educational
value" or "We are incompetent because it was a failure" to be of much
long term use either.
I do see admitting mistakes were made and fixing them, everyone else out
of the way, to be much more productive.

On a more practical note, could there be some sort of failsafe "battery
went phut so disconnect it" device? I'm guessing a perfectly ordinary
inline fuse would be too simple, but perhaps some sort of mechanical
latch that would just pop the battery terminal if it lost power would
work.

that is fairly common in many spacecraft (I have checked a few designs) and
most transport category airplanes. I dont have a clue why it wasnt put into

Diane. I concur in you're comments particularly that failure is not alone
an indicator of incompetence. (my words but hopefully it is fair to you're
thought)
What in engineering (and in life) signals incompetence is moving outside of
established engineering design parameters. Hence if one has a
specification that no foam comes off the tank and yet foam comes off the
tank on every flight...then dont be surprised when a big one comes off and
ruins your vehicle.
( a modest summation of the Columbia accident investigation board).
It is in my view not competent engineering to fly a payload, where the first
one failed and it was several orders of magnitude less complex then what one
is trying to fly now...and one has really no idea of why it failed.
How is the later important?
A prudent guess (and that is all it is) is that Suitsat 1 failed because
someone on the space station put the darn thing together wrong. or the
assembly instructions were wrong or...
If it worked on the ground and in the various test chambers then that is one
prudent method of investigation (AMSAT may know this already and just cannot
say it out loud because the mythic heroes on orbit never make mistakes!)
But before launching a far more complicated payload one might want to find
that out (the satellite might help them here if there is not a lot of
assembly to do on the station).
But a software derived transponder is not simple and if the thing
fails...most likely no one will know why. Was it some astronaut missed one
of those switches or is the entire program screwed? What to do with cubesat
then?
AMSAT's role should be as far as possible to keep the membership supplied
with functioning satellites. It is not the ham equivelent of DARPA or
whatever. If the role is not to keep hamsats in orbit, then what does it do

I think that you are correct..when Hubble was carried to Cape Kennedy AVLeak
reported that it arrived in the same carrier as the KH's used. There are
differences between the two I think, but the mirror is about the same (in my
opinion)
