 History and costs

Lockheed's covert "advanced projects" facility at Hiller Aircraft in Menlo Park, California.
CORONA started under the name "DISCOVERER" as part of the WS-117L satellite reconnaissance and protection program of the US Air Force in 1956. The WS-117L was based on recommendations and designs from the RAND Corporation.[sup][2][/sup] The United States Air Force credits the Onizuka Air Force Station (then called Sunnyvale Air Force Station) as being the "birthplace of the CORONA program".[sup][3][/sup] In May 1958, the Department of Defense directed the transfer of the WS-117L program to Advanced Research Projects Agency (ARPA). In FY1958, WS-117L was funded by the USAF at a level of US$108.2 million (inflation adjusted US$0.96 billion in 2020). For DISCOVERER, the Air Force and ARPA spent a combined sum of US$132.3 million in FY1959 (inflation adjusted US$1.16 billion in 2020) and US$101.2 million in FY1960 (inflation adjusted US$0.87 billion in 2020).[sup][4][/sup] According to John N. McMahon, the total cost of the CORONA program amounted to $US 850 million.[sup][5][/sup]
The CORONA project was pushed forward rapidly following the shooting down of a U-2 spy plane over the Soviet Union on 1 May 1960.[sup][6][/sup]
Design staffMinoru S. "Sam" Araki [de], Francis J. Madden [de], Edward A. Miller [de], James W. Plummer, and Don H. Schoessler [de] are responsible for the design, development, and operation of CORONA, the first space-based Earth observation systems. As a result, they were awarded Charles Stark Draper Prize in 2005.

The CORONA Satellite Index Camera Lens.The Corona satellites used special 70 millimeter film with a 24-inch (610 mm) focal length camera.[sup][7][/sup] Manufactured by Eastman Kodak, the film was initially 0.0003 inches (7.6 μm) thick, with a resolution of 170 lines per 0.04 inches (1.0 mm) of film.[sup][8][/sup][sup][9][/sup] The contrast was 2-to-1.[sup][8][/sup] (By comparison, the best aerial photography film produced in World War II could produce just 50 lines per mm (1250 per inch) of film.)[sup][8][/sup] The acetate-based film was later replaced with a polyester-based film stock that was more durable in Earth orbit.[sup][10][/sup] The amount of film carried by the satellites varied over time. Initially, each satellite carried 8,000 feet (2,400 m) of film for each camera, for a total of 16,000 feet (4,900 m) of film.[sup][8][/sup] But a reduction in the thickness of the film stock allowed more film to be carried.[sup][10][/sup] In the fifth generation, the amount of film carried was doubled to 16,000 feet (4,900 m) of film for each camera for a total of 32,000 feet (9,800 m) of film. This was accomplished by a reduction in film thickness and with additional film capsules.[sup][11][/sup] Most of the film shot was black and white. Infrared film was used on mission 1104, and color film on missions 1105 and 1008. Color film proved to have lower resolution, and so was never used again.[sup][12][/sup]
The cameras were manufactured by the Itek Corporation.[sup][13][/sup] A 12-inch (30 cm), f/5 triplet lens was designed for the cameras.[sup][14][/sup] Each lens was 7 inches (18 cm) in diameter.[sup][8][/sup] They were quite similar to the Tessar lenses developed in Germany by Zeiss.[sup][15][/sup] The cameras themselves were initially 5 feet (1.5 m) long, but later extended to 9 feet (2.7 m) in length.[sup][16][/sup] Beginning with the KH-4 satellites, these lenses were replaced with Petzval f/3.5 lens.[sup][12][/sup] The lenses were panoramic, and moved through a 70° arc perpendicular to the direction of the orbit.[sup][8][/sup] A panoramic lens was chosen because it could obtain a wider image. Although the best resolution was only obtained in the center of the image, this could be overcome by having the camera sweep automatically ("reciprocate") back and forth across 70° of arc.[sup][17][/sup] The lens on the camera was constantly rotating, to counteract the blurring effect of the satellite moving over the planet.[sup][12][/sup]

A diagram of "J-1" type stereo/panoramic constantly rotating CORONA reconnaissance satellite camera system used on KH-4A missions from 1963 to 1969.
The first Corona satellites had a single camera, but a two-camera system was quickly implemented.[sup][18][/sup] The front camera was tilted 15° aft, and the rear camera tilted 15° forward, so that a stereoscopic image could be obtained.[sup][8][/sup] Later in the program, the satellite employed three cameras.[sup][18][/sup] The third camera was employed to take "index" photographs of the objects being stereographically filmed.[sup][19][/sup] The J-3 camera system, first deployed in 1967, placed the camera in a drum. This "rotator camera" (or drum) moved back and forth, eliminating the need to move the camera itself on a reciprocating mechanism.[sup][20][/sup] The drum permitted the use of up to two filters and as many as four different exposure slits, greatly improving the variability of images that Corona could take.[sup][21][/sup] The first cameras could resolve images on the ground down to 40 feet (12 m) in diameter. Improvements in the imaging system were rapid, and the KH-3 missions could see objects 10 feet (3.0 m) in diameter. Later missions would be able to resolve objects just 5 feet (1.5 m) in diameter.[sup][22][/sup] A single mission was completed with a 1 foot (0.30 m) resolution but the limited field of view was determined to be detrimental to the mission.[sup][citation needed][/sup] 3 feet (0.91 m) resolution was found to be the optimum resolution for quality of image and field of view.

The initial Corona missions suffered from mysterious border fogging and bright streaks which appeared irregularly on the returned film. Eventually, a team of scientists and engineers from the project and from academia (among them Luis Alvarez, Sidney Beldner, Malvin Ruderman, Arthur Glines,[sup][23][/sup] and Sidney Drell) determined that electrostatic discharges (called corona discharges) caused by some of the components of the cameras were exposing the film.[sup][24][/sup][sup][25][/sup] Corrective measures included better grounding of the components, improved film rollers that did not generate static electricity, improved temperature controls, and a cleaner internal environment.[sup][25][/sup] Although improvements were made to reduce the corona, the final solution was to load the film canisters with a full load of film and then feed the unexposed film through the camera onto the take-up reel with no exposure. This unexposed film was then processed and inspected for corona. If none was found or the corona observed was within acceptable levels, the canisters were certified for use and loaded with fresh film for a launch mission.
The first satellites in the program orbited at altitudes 100 miles (160 km) above the surface of the Earth, although later missions orbited even lower at 75 miles (121 km).[sup][12][/sup] Originally, CORONA satellites were designed to spin along their main axis so that the satellite would remain stable. Cameras would take photographs only when pointed at the Earth. The Itek camera company, however, proposed to stabilize the satellite along all three axes—keeping the cameras permanently pointed at the earth.[sup][15][/sup] Beginning with the KH-3 version of the satellite, a horizon camera took images of several key stars.[sup][19][/sup] A sensor used the satellite's side thruster rockets to align the rocket with these "index stars," so that it was correctly aligned with the Earth and the cameras pointed in the right direction.[sup][26][/sup] Beginning in 1967, two horizon cameras were used. This system was known as the Dual Improved Stellar Index Camera (DISIC).[sup][21][/sup]
Satellites were calibrated using the Corona Satellite Calibration Targets located outside of Casa Grande, Arizona. The targets consisted of concrete arrows located in and to the south of the city, and helped to calibrate the cameras of the satellites.[sup][27][/sup][sup][28][/sup][sup][29][/sup]

I believe this is population control the government has use the word Corona before as a code name for a experiment who's to say this is an experiment to see if you'd leave your house or going to kill you
