woot!

Thanks for posting Sir. I was thinking about how the day's been going for those attending.
Remembering those who made the ultimate sacrifice for our rights & freedoms, and for those injured, visible or otherwise, in that fight.

Huh; it looks like there is a Maksutov-style spherical corrector lens between the first diagonal mirror and the primary at the rear. This make perfect sense from an imaging point of view (it's effectively a Maksutov-Newtonian, one of the preferred designs for small imaging telescopes), but that corrector lens must have been quite massive.

One distinct advantage, though, would be that both the primary mirror and the corrector lens would be spherical, which is much, much easier to grind than the parabolas and hyperbolas of more advanced designs. Also, Maksutov optics can be quite easily fixed in place (no delicate spiders), meaning they can take a much wider range of accelerations (i.e. during a rocket launch).

Veil of secrecy lifted on Kodak spy satellite work

During the hard frost of the Cold War, a time when people were building fallout shelters in their basements, an extensive team of people from what was then a division of Eastman Kodak Co. worked on spy satellite programs that may have helped prevent a third world war.

Here is one volume of a photo-interpretation report from GAMBIT mission 4030, in July 1966.

Warning: big file.

They didn't use the black out approach to deletions. They just used blank boxes, which is far easier on your toner cartridge. But look for yourself.

By the way, there are TONS of these reports from CORONA that are available, fewer for GAMBIT. After you start looking at this stuff you get a sense of just how much material was produced by each reconnaissance flight. For later CORONA missions, if you printed out all the reports for a mission, you would end up with a stack a couple of feet high. No kidding.

Speaking of Sary Shagan, Google Earth has a bunch of Panoramio dots of the former Soviet facilities there, and the place is absolutely trashed.  It almost looks as if the Soviets deliberately destroyed many of the buildings when they left.

Has anybody seen any mention in the various GAMBIT histories of changes in the launch tower configuration at Vandenberg leading to acoustic damage to the spacecraft that caused malfunctions in flight?

Somebody told me about this years ago, but I don't recall seeing any reference to it in the histories. I'm trying to help somebody who is writing an article about how changes to a launch pad or spacecraft led to failures that were never predicted.

I don't understand where are located the two re-entry capsules on KH-7...

Someone could explain ?

KH-7, or GAMBIT-1, had only a single reentry vehicle. You can see it in the above image. It is the gray thing at left.

The first GAMBIT-3s had only a single reentry vehicle. Eventually they started mounting two of them, one behind the other, just like on the KH-4A and 4B models of CORONA.

Here is the KH-8, which shows how the reentry vehicles were mounted. Somebody pointed out to me that they are not exactly one behind the other. The second one is slightly offset from center.

Was over at the Smithsonian this morning when they wheeled in their GAMBIT-1 satellite. Here it is on display a few minutes before the museum opened.

I'll have an article about the installation with a bunch more photos (I got photographs of it coming off the truck, being unwrapped, pushed into position, etc. Also photos of the interior, the camera door cover, etc.)

Timing couldn't be better; I plan on taking my sons to the Smithsonian this summer. I'll make sure to point out the parts of this that were made by their neighbors.

GAMBIT in the house
by Dwayne Day
Monday, July 6, 2015

On July 12, 1963, the first of the top secret GAMBIT reconnaissance satellites sailed into a California sky atop an Atlas-Agena rocket. On June 30, 2015, one of the last remaining GAMBITs finally appeared at the Smithsonian’s National Air and Space Museum in Washington, DC—eighteen years after its owners and Smithsonian officials had first discussed displaying it.

The CIA posted an article about the U-2 at Area 51 today:

https://www.cia.gov/news-information/featured-story-archive/2015-featured-story-archive/area-51-u-2-and-the-accidental-test-flight.html

The article includes a number of images of U-2 operations at Area 51/Groom Lake. I don't know for sure, but I think that many of these are previously unpublished. They really give you a feeling for the remoteness and the isolation of the location.
