Hmm, maybe a digital KH-8 would be a good idea, especially with the lower cost launchers like Minotaur or Delta II available as well as their future equivalents.
Recently, I read the Orlets-2 Yenisey sats had alledgedly resolutions "capable of spotting matchsticks". Would this make them more powerful than the KH, or is it a legend?
---And the time that the National Reconnaissance Office used one to photograph the crippled Skylab space station.---Are the pics available somewhere ?
Some illustrations I'm using on Monday.
Nice long article, worth the read...
Quick question, do you think the solar panel layout would be similar to the Seasat's?
Not to be greedy, but at what time does the site update? 11:30 am EST and still on last week

It will probably be #3 or #4 in a series. The series will probably be:1-the origins of the Samos recoverable satellites and the proposals for a "covert satellite" using an ICBM2-the Samos E-6 satellite and the SPARTAN (half E-6) program3-the KH-7 and KH-8 GAMBITI might split 3 into two parts to become 3 and 4. In addition, I have new information on the KH-6, developed from the Samos E-5, and that could possibly fit in between parts 2 and 3. Dunno. Gotta get off my butt and submit part 1.Quote from: kevin-rf on 01/12/2009 06:04 pmQuick question, do you think the solar panel layout would be similar to the Seasat's?I don't know. Corona mission 1115, which flew in Sept 1971, was a single panel that extended out from the aft rack of the Agena (I've got an illustration of it from a declassified history that I could scan and post in a few days). It looks a lot like the arrays on the Apollo Telescope Mount on Skylab.Presumably you could fit two of these. This may have been the Seasat array a few years later. I don't think that power requirements for KH-8 were all that high, especially compared to Seasat with a radar. So maybe KH-8 only carried one array, or two short ones.However, we don't have good documentation on the solar panels carried by _any_ Agena. I don't know when they were first carried at all, although they were projected for early Samos and Midas. So we don't know anything about what kinds of solar panels were developed for Agena and when.Here's another question--how do you bring a KH-8 down for a low pass with that array? Do you pull it in and then deploy it? Do you fly only a single array?
I'm not sure exactly how low the KH-8s went, but if the solar array was edge-on to the direction of flight, the drag could be manageable.
