255.1 | Today AW should have more | IMNAUT::BIRO | | Mon Feb 09 1987 10:27 | 7 |
| say one more article about it, said that AW 9/feb/87 had an article
about it but said it was the fourth stage, they also said that one
of the recon sat fail to send its package back to earh an it was
blown up to prevent the american from getting it, I wonder how they
though we would be able to get it?

| The Space Shuttle (when it gets back into space again, naturally).
The Soviets have always feared its satellite retrieval
capabilities, among other aspects.

255.3 | maybe ... | IMNAUT::BIRO | | Mon Feb 09 1987 11:33 | 11 |
| I'm not sure, if it was in a low orbit(as most recon are) then its orbit
would most likly have decayed before the next possible Shuttle,
the only other thing I could think of, the unit is design for reentry
and it is possible it may not burn up in an uncontroled reentry
and we could then have a fox hunt winner takes all (if it came down
in friendly waters)
will have to wait till I get home an see what AW has to say

255.4 | GOTCHA! | EDEN::KLAES | Nobody expects the Spanish Inquisition! | Mon Feb 09 1987 11:42 | 9 |
| By any chance would the United States happen to have a "satellite
grabber" - an automated satellite which prowls around in Earth's
orbit, ready to capture any interesting Soviet (or other "unfriendly")
satellites, place them in a compartment, and either wait for a Space
Shuttle to pick them up, or return to Earth by itself? Is such a thing
possible/practical?

255.5 | retrevial probe | ENGGSG::FLIS | | Mon Feb 09 1987 11:51 | 8 |
| I have heard discussion concerning the use of a robot probe that
would be able to attain the 23,000 mile geosync orbit altitude for
the purpose of bringing disabled sats down to shuttle orbital altitude
such that they could be repaired or returned to earth. Such a probe
would work fine for what you suggest.

| Most of the Soviet low altitude photo recon sats are based on the
Vostok design. The reentry capsule of a Vostok could survive reentry
after orbit decay, so there would have been a reasonable chance
of recovery by 'unfriendly' forces.

| It's amazing how the Soviets still use designs that date back
to the early days of the Space Age!

| If it aint broke, don't fix it....
This is one of the major differences between the US and Soviet space
program. One side likes to reuse existing technology, sometimes
pushing it beyond its envelope and the other like to develope new
technology even when existing technology will suffice. Both approaches
have their problems.

255.9 | Cover bird with foil, do not poke holes with fork | DENTON::AMARTIN | Alan H. Martin | Mon Feb 09 1987 22:36 | 17 |
| Re .1:
Blown up from without or within?
If the latter, it ought to provide (further?) proof that you don't want
to drag a Russian satellite inside a shuttle cargo bay without asking
permission.
Although, if a positive radio signal is required as a failsafe method
of preventing unwanted self-destruction, then jamming until you can
cover the bird with Reynold's Wrap might do.
Re .5:
Judging from the above, it might be interesting to watch for a robot
that can deorbit its cargo without placing it in a shuttle.

255.10 | AW add a little | IMNAUT::BIRO | | Tue Feb 10 1987 07:51 | 16 |
| AW did not add much to the destruction of the spy sat
but the remote control does not have to be from a radio signal the bird
could have AI or simple detectors to check or any nearby object,
is there anyone near me, pooof.... I have heard rumors that recon
sat are protect by such system also mil com sat are rumored to
have defense against sat killers form getting to them, thus space
salvaging could be a dangerous job.
As for the tanks, that is a nice idea of using then as stroage
tanks, nice to be able to use them as fuel tanks for a mission to
Mars or just to get home etc
As to the failed launch, it was suposed to be a communications sat
but not much on it as the CCCP are keeping it quite as not to scare
away customers, most likly a geo bird.

255.11 | More trouble than it's worth? | CYGNUS::ALLEGREZZA | George Allegrezza | Tue Feb 10 1987 11:44 | 26 |
| The target satellite might be equipped with a relatively simple proximity
fuze, set to detonate a small warhead if anything gets within x feet. This
would be completely autonomous and hard to spoof. Or, they could be
equipped with active defenses, such as small long-wave IR-homing or
millimeter-wave-homing missiles, again set to fire at co-orbital bodies
within a certain range.
Also, a grabsat would have to enter the same orbit as the target, for at
least part of one revolution. This would certainly flag Soviet space
surveillance and possibly the anti-sat laser at Sary Shagan (sp?) could be
used against the grabsat? (provided the grab was attempted over the
eastern hemisphere.)
An easier way to get our hands on at least the recon data would be to figure
a way to initiate separation and re-entry of the recovery capsule, and
direct it to land in the US. Then we take it to Fort Detrick to open it
up, because our vodka-drinking buddies might have put a CBW toxin inside
the capsule as a precaution.
What do you suppose we'd find in a Soviet reconsat? Zeiss lenses, Fuji
film, and some Intel M8086s, I guess. It probably wouldn't be worth the
effort.
The Soviets have been on the propaganda bandwagon for years about the
shuttle being used as a grabsat. They'd NEVER try such a thing with their
shuttle, however. Just ask Phil Donahue or Ted Turner.

255.12 | RE 255.11 | EDEN::KLAES | Nobody expects the Spanish Inquisition! | Tue Feb 10 1987 11:49 | 8 |
| What about this anti-sat laser at "Sary Shagan"?
BTW - I like grabsat. I think their purpose if nothing else
could be to intimidate Soviet military satellites. They do, of
course, have many civilian uses as well.

255.13 | Is for testing, comrade Phil | CYGNUS::ALLEGREZZA | George Allegrezza | Tue Feb 10 1987 12:55 | 8 |
| The Soviets have been testing a giant chemical laser at their Sary
Shagan (I think that's the spelling) test site in central Asia for
years. The CIA feels that, since it isn't as elegant as something
Hughes would design (Aircraft, not Gary), it can't be an operational
device. The DIA and the Air Force say that test rig or no test
rig, it's powerful enough to damage a satellite in LEO.
I'll try to find some solid references to this.

255.14 | Icantthinkofaname | IMNAUT::BIRO | | Tue Feb 10 1987 14:26 | 17 |
| that is a new laser site , there was strong rumors that they have
been able to blind our survalance sat for many years now even to
the point of doing damage to delicate electronic sensors but the
Sary Shagan seems to be a bigger unit from your description.
The equipment used in the spy sat would most likly be made in
japan etc, but what they consider important to photo or elctronicly
listen to would be worth it
but even in the us our sat are no all us design, one of the partical
acellerator design to be used in SDI is a Soviet design that got them
the Nobel Peace Prize a few years ago
However we may think to hightly of ourself, they could have destroyed
it just to keep it from doing damage, as it could have made it threw
the orbit decay , and who needs a footfall

| I think it would be more interesting to find out what they were
photographing than how. The only likely piece of technology information
would be resolution capability (assuming no major secret breakthrough
by the Soviets).
I do recall something about a large ground based Soviet laser, prob
in an old AW&ST.

| Aviation Week first broke the story in 1977, when it published an interview
with Gen. George Keegan, the retiring head of Air Force Intelligence.
They continued to update the story until late 1984, when Military Editor
Clarence Robinson left the mag. and a lot of their sources dried up.
Another account is offered in David Baker's book, _The Shape of Wars to
Come_, (Stein & Day, 1982).
Baker described the Soviet directed energy test site at Saryshagan (one
word), an isolated (!) area about 60km from the Soviet underground nuke
test site at Semipalatinsk (sp?). The pulsed oxygen-iodine laser which I
alluded to earlier operates in the visible light portion of the spectrum,
and has been tested against objects in the atmosphere. It may have enough
power to operate as a true anti-sat weapon; it certainly has enough power
to craze the optics of an observation satellite, and probably damage many
of the electronic systems on board any type of bird.
Also mentioned as being tested at Saryshagan are magnethydrodynamic
generators driven by liquid rocket engines, and particle beam generators
which are powered by electricity generated by small underground nuclear
explosions.
Sorry to have diverged so far from the base note!

255.17 | take your pic | IMNAUT::BIRO | | Thu Feb 12 1987 09:07 | 12 |
| yes back off track again but why not, it is an interesting road to travel
You can do a good guess as to what they are taking pic of by ploting
the Aperigee and Perigee, when the sat dips you can plot its low
point and look for other clues like local Noon for best light
mid afternoon for good shadows pic etc, typical they only make
about 15 trips per day around the earth and most points at best picture
taking time can be ruled out, for example one drop down to take
good pictures of the Falkland Is area when that was heating up
the problem is geting good elementset and updates, several
interesting article have been written on how to do it with
visulal observations over several nights
