Twenty-four U-2 missions produced images of about 15 percent of the country with a maximum resolution of before the downing of a U-2 in 1960 abruptly ended the program. This left a gap in American espionage capabilities that it was hoped spy satellites would be able to fill.

One benefit of the Sputnik crisis was that no government protested Sputnik's overflying their territory, thereby tacitly acknowledging the legality of satellites. While there was a big difference between the innocuous Sputnik and a spy satellite, it made it much harder for the Soviets to object to overflights by satellites from another country.

McNamara called for a review of whether Dyna-Soar had military capabilities that could not be met by Gemini, on 18 January 1963. In his 14 November 1963 response, the Director of Defense Research and Engineering (DDR&E), Harold Brown, examined options for a space station. He preferred a four-man station that would be launched separately and crewed by astronauts arriving in Gemini spacecraft. Crews would rotate every 30 days, with resupply of consumables arriving every 120 days. On 10 December 1963, McNamara issued a press release that officially announced the cancellation of Dyna-Soar, and the initiation of the MOL program.

, Douglas, General Electric and Lockheed were selected to carry out design studies. Covert NRO activities to be carried out by MOL were classified secret and given the code name "Dorian". In February 1969, the MOL was given a Keyhole (reconnaissance satellite) designation as KH-10 Dorian.
As a black project (i.e. one that was secret and publicly unacknowledged), but one that was impossible to completely conceal, MOL needed some "white" (i.e. unclassified and publicly acknowledged) experiments as cover. An MOL Experiments Working Group was created under Colonel William Brady. Some 400 experiments proposed by several agencies were examined. These were consolidated and reduced to 59, and twelve primary and eighteen secondary ones were selected. A 499-page report on the experiments was issued on 1 April 1964. Although reconnaissance was its main purpose, "manned orbiting laboratory" was still an accurate description; the program hoped to prove that astronauts could perform militarily useful tasks in a shirt-sleeve environment in space for up to thirty days.
The USAF recommended that the MOL use the Gemini B spacecraft with the Titan III booster. A program of six flights (one uncrewed and five crewed) was proposed, the first flight taking place in 1966. The program was costed at US$1.653 billion (equivalent to $ billion in ). The Science Advisor to the President,

He noted that for the sophisticated reconnaissance missions proposed, a human-operated system was far superior to an automated one, but speculated that with sufficient effort, the gap between the two could be reduced. He also noted that while countries had not objected to satellites passing overhead, a crewed space station might be a different matter, but the Secretary of State, Dean Rusk, thought that this could be managed.
There remained the question of whether the improved performance compared to the automated KH-8 Gambit 3 satellite then under development justified the cost. The

In late 1965, the USAF began selecting a second group of MOL pilots. This time applications were accepted. Selection occurred at the same time as that for NASA Astronaut Group 5, many applying to both programs. Successful candidates were told that NASA or MOL had chosen them, with no explanation why they had been chosen by one and not the other. Over 500 applications were received, from which 100 names were forwarded to USAF Headquarters.

Truly was amazed to learn that his country had not one but "two space programs: the public, what the public knew and ASAastronauts and all that jazz, and then this other world of capability that didn't exist".
Phase I of crew training was a two-month introduction to the MOL program in the form of a series of briefings from NASA and the contractors. Phase II lasted for five months, and was conducted at the ARPS, where the astronauts were given technical training on the MOL vehicles and their operation procedures. This training was conducted in classrooms, in training flights, and in sessions on the T-27 space flight simulator. Phase III was continuous training on the MOL systems and providing crew input to them. The pilots spent most of their time in this phase. Phase IV was training for specific missions.
Simulators were developed for each of the different MOL systems: Laboratory Module Simulator, Mission Payload Simulator, and Gemini B Procedures Simulator. Zero-G training was conducted in a Boeing C-135 Stratolifterreduced-gravity aircraft. A Flotation-Egress trainer allowed the astronauts to prepare for a splashdown and the possibility of the spacecraft sinking. NASA had pioneered

From the MOL's regular orbit, the main camera had a circular field of view across, although at top magnification it was more like . This was much smaller than many of the targets that the NRO was interested in, such as air bases, shipyards and missile ranges. The astronauts would search for targets using the tracking and acquisition telescopes, which had a circular view of the landscape about across, with a resolution of about . The main camera would focus on the most important targets, providing a very high resolution image. The aim was to have the most interesting part of the target in the center of the image; due to the optics used, the image would not be as sharp around the edges of the frame.
While surveillance targets were pre-programmed and the camera could operate automatically, astronauts could decide target priority for photographing. By avoiding cloudy areas and identifying more interesting subjects (an open missile silo instead of a closed one, for example), they would save film, the major limitation, since it had to be returned in the small Gemini B spacecraft. In cloudy areas like

, it was estimated that the MOL would be 45 percent more efficient in its use of film than an automated satellite system through the ability to react to cloud cover, but for sunnier areas like the Tyuratam missile complex, this might be no more than 15 percent. The selective targeting afforded by human-guided surveillance would be more efficient than that obtained by robotic satellites. Of the 159 KH-7 Gambit photographs of the Tyuratam area, only 9 percent showed missiles on the launch pads, and of 77 photographs of missile silos, only 21 percent were with the doors open. The analysts identified 60 MOL targets in the complex. Only two or three could be photographed on each pass, but astronauts could select the most interesting ones on the spur of the moment, and photograph them with greater resolution than KH-7 Gambit. It was hoped that valuable technical information would thereby be obtained.
The Air Force expected that an improved version of the MOL space station, known as Block II, expected to be available for the sixth crewed flight in July 1974, would add image transmission and geodetic system targeting. Astronauts would perform

, multispectral, and ultraviolet astronomy when they had time during an extended mission duration on twice-annual flights. After Block II, the MOL program managers hoped to build larger, permanent facilities. A planning document depicted 12-man and 40-man stations, both with self-defense capability. It described the 40-man, Y-shaped station as a " spaceborne command post" in synchronous orbit. With the "key requirementpost attack survivability", the station would be capable of "Strategic/tactical decision making" during a general war.

Spacecraft
The Gemini spacecraft originated at NASA in 1961 as a development of the Mercury spacecraft, and was originally called Mercury Mark II. The name "Gemini" was chosen in recognition of its two-man crew. The NASA Gemini spacecraft was redesigned for the MOL and named Gemini B, although the NASA Gemini spacecraft was never referred to as Gemini A. The astronauts would fly into space in the Gemini B capsule, which would be launched together with the MOL modules atop a Titan IIIM

. Once in orbit, the crew would power down the capsule and activate and enter the laboratory module. After about one month of space station operations, the crew would return to the Gemini B capsule, power it up, separate it from the station, and perform reentry. Gemini B had an autonomy of about 14 hours once detached from MOL.
Like the NASA Gemini, the Gemini B spacecraft would splash down in the

under development to enable a Gemini spacecraft to paraglide to a dry-land touch-down, but was unable to get it working in time for Project Gemini missions. In March 1964, NASA attempted to get the USAF interested in using the paraglider with Gemini B, but after reviewing the troubled paraglider program, the USAF concluded that the paraglider still had too many problems to overcome, and it turned down the offer. The MOL laboratory module was intended to be used for a single mission only, with no provision for a later mission to dock and reuse it. Instead, its orbit would decay and it would be dumped in the ocean after 30 days.
Externally Gemini B was quite similar to its NASA twin, but there were many differences. The most noticeable was that it featured a rear hatch for the crew to enter the MOL space station. Notches were cut into the ejection seat headrests to allow access to the hatch. The seats were therefore mirror images of each other instead of being the same. Gemini B also had a larger diameter heat shield to handle the higher energy of reentry from a

(OAMS), because capsule orientation for reentry was handled by the forward reentry control system thrusters, and the laboratory module had its own reaction control system for orientation.
The Gemini B systems were designed for long-term orbital storage (40 days), but equipment for long duration flights was removed since the Gemini B capsule itself was intended to be used only for launch and reentry. It had a different cockpit layout and instruments. As a result of the Apollo 1 fire in January 1967, in which three NASA astronauts were killed in a ground test of their spacecraft, the MOL was switched to use a helium-oxygen atmosphere instead of a pure oxygen one. At takeoff, the astronauts would breathe pure oxygen in their spacesuits while the cabin was pressurized with helium. It would then be brought up to a helium-oxygen mix. This was an option that had been provided for in the original design.
Four Gemini B spacecraft were ordered from McDonnell, along with a boilerplate aerodynamically similar test article, at a cost of US$168.2 million (equivalent to $ million in ). In November 1965, NASA agreed to hand over

Spacesuits
The MOL program's requirements for a spacesuit were a product of the spacecraft design. The Gemini B capsule had little room inside, and the MOL astronauts gained access to the laboratory through a hatch in the heat shield. This required a more flexible suit than those of NASA astronauts. The NASA astronauts had custom-made sets of flight, training and backup suits, but for the MOL the intention was that spacesuits would be provided in standard sizes with adjustable elements. The USAF sounded out the David Clark Company,

At least 17 blue MOL MH-7 training suits were delivered between May 1968 and July 1969. A single MH-8 flight configuration suit was delivered in October 1968 for certification testing. The flight suit was intended to be worn during launch and reentry.
The contract for the launch/reentry suit was followed by a second competition in September 1967 for a suit for

As a result, an astronaut maneuvering unit (AMU) was developed and integrated with the life support system as an integrated maneuvering and life support system (IMLSS). The design was completed by October 1968, and a prototype without cover garments was delivered in March 1969. The cover garments were never completed.

s had performed a "dog leg" maneuver, flying east and then south to avoid southern Florida. This required special State Department approval, as it meant overflying Cuba. The loss of an MOL with a classified payload over Cuba would be not only a danger to life and property, but a serious security concern as well. Moreover, the dog leg maneuver would reduce the orbital payload by , reducing the equipment that could be carried or the duration of the mission or both. The cost of construction of a Titan III facility, including the purchase of the land, was estimated to be US$31 million (equivalent to $ million in ), and the required supporting ground equipment would cost another US$79 million (equivalent to $ million in ).

To allay Soviet fears that the MOL would carry nuclear weapons, the State Department suggested that Soviet officials be permitted to inspect it for them before launch, but Brown opposed this on security grounds.

s, but without knowing their capabilities or those of MOL, could not evaluate the actual costs or benefits of the program.
Publicly, the Air Force vaguely described the MOL as "an effective space building block of very substantial potential, a space resource capable of growth to follow-on tasks". "On completion", Brady declared in 1965, "we will have configured, acquired, and most important, conducted a manned military space operation thereby acquiring the crews, experience and equipment that will, if required, allow the Air Force to move into the near-earth space environment in an orderly and effective manner".
The Soviet Union commissioned the development of its own military space station,
Almaz
The Almaz (russian: Алмаз, lit=Diamond) program was a highly secret Soviet military space station program, begun in the early 1960s.
Three crewed military reconnaissance stations were launched between 1973 and 1976: Salyut 2, Salyut 3 ...
. This project was initiated by chief-designer Vladimir Chelomey on 12 October 1964, but it was Johnson's announcement of the MOL program on 25 August 1965 that led to the Almaz project receiving official endorsement and funding on 27 October 1965. Three Almaz space stations flew as Salyut space stations between 1973 and 1976 before the crewed Almaz program was canceled in 1978.
Delays and cost increases
Within weeks of Johnson's announcement of the MOL program, it was facing budget cuts. In November 1965, Flax arbitrarily cut US$20 million (equivalent to $ in ) from the MOL program's fiscal year 1967 budget, bringing it down to US$374 million (equivalent to $ million in ). Brown learned that McNamara intended to limit the program to US$150 million (equivalent to $ million in ) in fiscal year 1967, the same allocation as in fiscal year 1966, in response to the rising cost of the

. In August 1965, the first uncrewed qualification flight had been expected to take place in late 1968, with the first crewed mission in early 1970, on the assumption that engineering development would commence in January 1966. Since this was now unlikely, McNamara saw no reason to continue with the original budget. Brown examined the schedules, advising McNamara that a crewed mission in April 1969 would require a minimum of US$294 million (equivalent to $ million in ) in fiscal year 1967, and that the minimum budget that the MOL program required was US$230 million (equivalent to $ million in ), which would impose a delay of the first flight of three to eighteen months. McNamara was unmoved, and US$150 million (equivalent to $ million in ) was the sum requested in the budget submitted to Congress in January 1966.
When the MOL engineering development phase commenced in September 1966, it became clear that the USAF estimates of project costs and those of the major contractors were a long way apart. McDonnell requested US$205.5 million (equivalent to $ million in ) for a fixed price plus incentive fee (FPIF) contract to design and build Gemini B, which the USAF budgeted at US$147.9 million (equivalent to $ million in ); Douglas wanted US$815.8 million (equivalent to $ million in ) for the laboratory vehicles which the USAF budgeted at US$611.3 million (equivalent to $ million in ); and General Electric sought US$198 million (equivalent to $ million in ) for work budgeted at US$147.3 million (equivalent to $ million in ). In response the MOL SPO reopened negotiations for systems not under contract, and halted the issuance of Dorian clearances to contractor personnel. This had the desired effect, and by December 1966, the major contractors had reduced their prices, bringing them closer to the USAF estimates. However, on 7 January 1967, the Office of the Secretary of Defense (OSD) informed the MOL SPO that it intended to limit contracts in fiscal year 1968 to US$430 million (equivalent to $ million in ), which was US$157 million (equivalent to $ million in ) short of what the MOL SPO wanted, and US$381 million (equivalent to $ million in ) below what the contractors wanted. This meant that the prime contracts had to be renegotiated.
Budget cuts were not the only reason for the project's schedule slipping. On 9 December 1966, Eastman Kodak advised that it would not be able to deliver the optical sensors by the original target date of January 1969 for a crewed mission in April 1969, and asked for a ten-month extension to October 1969, which pushed the date of the first crewed mission back to January 1970. Eventually, US$480 million (equivalent to $ million in ) was found for fiscal year 1968, with US$50 million (equivalent to $ million in ) obtained by reprogramming funds from other programs, and US$661 million (equivalent to $ million in ) agreed upon for fiscal year 1969. To accommodate this, the date of the first qualification flight was pushed back still further, to December 1970, with the first crewed mission in August 1971.
On 17 May 1967, a US$674,703,744 FPIF contract (equivalent to $ in ) was signed with Douglas, which also received US$13 million (equivalent to $ million in ) in black budget funds. A US$180,469,000 FPIF contract (equivalent to $ in ) was signed with McDonnell the following day, and a US$110,020,000 (equivalent to $ in ) to

, which was expected to receive another US$60 million in black budget funds (equivalent to $ million in ). The delays increased the projected costs of the MOL program to US$2.35 billion (equivalent to $ billion in ). Aware of the program's budgetary and political difficulties, the astronauts in early 1968 advised Bleymaier to eliminate the uncrewed qualification missions; the August 1971 crewed flight would be the first MOL launch and first operational mission. In March 1968, Congress appropriated US$515 million (equivalent to $ million in ) for fiscal year 1969, and the MOL SPO was directed to plan on the basis of a US$600 million appropriation (equivalent to $ million in ) for fiscal year 1970. This entailed yet another schedule slippage. On 15 July 1968, the MOL SPO convened a conference with major contractors in Valley Forge, Pennsylvania, and it was agreed to defer the first crewed mission from August to December 1971.
Usefulness of humans
A few months after MOL development began, the program began developing an automated MOL that replaced the crew compartment with film reentry vehicles. Human reconnaissance from space was tested on Gemini 5 in 1965, which conducted 17 USAF military experiments, including photographing missile launches from Vandenberg Air Force Base, and observations of the

. As automated technology improved, however, those within the MOL program increasingly feared that astronauts were being eliminated. Al Crews said "it became obvious that all we were was a backup in case the unmanned reconnaissance system didn't work". Although Crippen did not think automation could completely replace astronauts, he agreed with Crews that automation technology was rapidly improving.
In February 1966, Schriever commissioned a report examining humans' usefulness on the station. The report, which was submitted on 25 May 1966, concluded that they would be useful in several ways, but implied that the program would always need to justify the cost and difficulty of the MOL versus a robotic version. Although it did not fly until July 1966, the authors were aware of the capabilities and limitations of the KH-8 Gambit 3. It could not achieve the same resolution as the Dorian camera on MOL, and the automation necessitated a longer development time and added weight, but the Dorian camera had a resolution of , could remain in orbit longer, and carry more film than earlier spy satellites.
The report concluded that crewed systems had many advantages over automated ones, which lost up to half their images to cloud cover on a typical mission. A human could select the best angle for a photograph, and could switch between color and infrared, or some other special film, depending on the target. This was especially useful for dealing with camouflaged targets. The MOL also had the ability to change orbits, and could shift from its regular orbit to a one, giving it a view of the entire Soviet Union.
The report's authors believed that unmanned MOL would more likely fail early missions and slowly improve, while manned MOL would be "self-healing" and crews would not repeat mistakes. Experience on Projects Mercury, Gemini and the X-15 had demonstrated that crew initiative, innovation and improvisation was often the difference between success and failure of the mission. Because of the early failures, they predicted that unmanned MOL would always be less successful overall than manned MOL regardless of the number of missions. After manned MOL perfected the system the program could fly both unmanned and manned missions, the report stated.
Debate also persisted about the value of the very high resolution (VHR) imaging being developed for MOL and KH-9 Hexagon, or whether the resolution provided by Gambit 3 was sufficient. After the ''Liberty'' incident in June 1967 and the ''Pueblo'' incident in January 1968, there was an increased focus on intelligence gathering by satellite. The Director of Central Intelligence,

, commissioned a report on the value of VHR, which was completed in May 1968. It concluded that it would help identify smaller items and features, and increase the understanding of Soviet procedures and processes, and the capacities of some of its industrial facilities, it would not alter estimates of technical capabilities, or assessments of the size and deployment of forces. Whether the benefit justified the cost was unclear, but by 1968 USAF decided that the automated system's longer development time and less certain capability meant that first MOL missions required astronauts. Later ones could be crewed or automated as needed.

, on the MOL, which Stewart described as the best path to VHR at the earliest date. Laird, who as a congressman had criticized McNamara for inadequately funding the MOL program, was favorably disposed towards the MOL program, as was Seamans, who was now the Secretary of the Air Force. On 6 March, Packard directed Foster to proceed on the basis of $556 million for fiscal year 1970 (equivalent to $ million in ). This entailed postponement of the first crewed mission to February 1972.
The Bureau of the Budget did not accept Laird's decision. Mayo argued that the resolution provided by Gambit 3 was adequate, and proposed canceling both the MOL and Hexagon. An MOL mission was expected to cost $150 million (equivalent to $ million in ), but a Gambit 3 launch cost only $23 million (equivalent to $ million in ). The value of VHR, Mayo argued, was not worth the extra cost. On 9 April, Nixon reduced the MOL's funding to $360 million (equivalent to $ million in ), and canceled Hexagon. This meant further postponement of the first crewed flight, by up to a year, and the Bureau of the Budget continued to press for the MOL to be canceled. In a last ditch attempt to save the MOL, Laird, Seamans and Stewart met with Nixon at the White House on 17 May, and briefed him on the history of the program. Seamans even offered to find $250 million (equivalent to $ million in ) to continue the program from elsewhere in the USAF budget. They thought the meeting went well, but Nixon accepted the Bureau of the Budget's recommendation to reverse his decision to cancel Hexagon and to cancel the MOL instead.
On 7 June 1969, Stewart ordered Bleymaier to cease all work on Gemini B, the Titan IIIM and the MOL spacesuit, and to cancel or curtail all other contracts. The official announcement that the MOL had been canceled was made on 10 June.
Had it flown as scheduled, MOL would have been the world's first space station. Some believed that MOL should have launched astronauts before the optics were ready. Abrahamson later concurred that his and other MOL astronauts' advice to fly the first mission fully operational was a mistake. He learned while serving as Deputy Administrator of NASA in the early 1980s that launching anything, even "an empty can", made cancellation of a project less likely. Al Crews believed that automated systems were probably superior, and said that when he saw high-resolution photographs from Gambit 3 he knew that MOL would be canceled. Lew Allen,

The civilians were reassigned to the Space and Missile Systems Organization (SAMSO). The service personnel included fourteen of the seventeen MOL astronauts.
