Talk:KH-9 Hexagon

The failed recovery of one of the film canisters from the first KH-9 HEXAGON satellite

Here is a well-written news source (secondary source) article on the failed initial Air Force recovery and Pacific Ocean sinking (in 3 miles of water, in 1971), and the eventual (1972) Navy underwater recovery of the film canister from the first KH-9 mission: The flight of the Big Bird (part 3), in The Space Review, February, 2011. Would be useful to any editor who wants to improve that part of the Wikipedia article. Cheers. N2e (talk)

The second of these turns out to be used to cite facts which are not in said press release; I found a copy of the press release at the third-party site http://www.spaceref.com/news/viewpr.html?pid=9535. So just deleted the offending sentence. Asa Zernik (talk) 11:54, 8 January 2018 (UTC)

Film Payload

How big was the payload? What was the size of the negative and how many photos were taken by each 'pod'? — Preceding unsigned comment added by 70.51.28.241 (talk) 01:51, 20 June 2019 (UTC)

That's described here https://m.youtube.com/watch?v=MmWlw8Ufo6Q 30 miles of 1/2000 of an inch thick film, each satellite containing 4 canisters "the film was six six point six inches

wide and it went over rollers slightly

longer than that the rollers were about

this diameter of my finger and it was

about two thousandths of an inch thick

and at the beginning of the program each

of the two cameras carried 20 miles of

film the film was supplied by the kodak

corporation as they made improvements in

film technology they developed color

film that we could use so we had miles

of black-and-white and color film

throughout they were also able to make

the thin film thinner to one and a half

thousands of an inch approximately so at

the near the final missions which could

last the beginning we had missions about

52 days and then eventually we wound up

with high reliability we had missions

that with 285 days the film got thinner

so the last missions had as much as 30

miles of film for each camera they were

stored on huge 6-foot diameter the reels

were 6 feet in diameter held in a

pressurized container" — Preceding unsigned comment added by 163.158.179.1 (talk) 20:06, 14 March 2022 (UTC)

Unsure on licensing, but Found some Information/Media

• The International Spy Museum has This Page Titled "HEXAGON Take-up reel" and a corrsosponding pictoure+basic summary.
• I am unsure on if this is open enough licensing wise to be used on Wikipedia, but i'll leave that for someone more qualified i guess
