The uprated Saturn I - consisting of an S-IB stage, S-IVB stage, and an instrument unit - boosted an unmanned payload into an original orbit of 185 by 189 kilometers. The inboard engine cutoff of the first stage occurred after 2 minutes 18 seconds of flight and the outboard engine cutoff was 4 seconds later. The S-IVB engine burned 4 minutes 50 seconds. No recovery was planned and the payload was expected to enter the earth's atmosphere after about four days. References: 2, 6, 16, 26, 27.

Kamanin is furious. Mishin and Tyulin think an engineer can be trained to be a spacecraft commander in three months, without passing a flight physical, without being a qualifed pilot, without screening and training on the centrifuge or zero-G aircraft, and without parachute training. They put no value in six years of VVS experience in cosmonaut training. They give no weight to the years of general training, spaceflight experience, and ten months of Soyuz-specific training his candidates have already had. He notes that the United States trains crews for a minimum of one to two years before a flight. Kamanin says this decision will not stand. References: 376.

The Gemini X mission began with the launch of the Gemini Atlas-Agena target vehicle from complex 14. The Gemini Agena target vehicle (GATV) attained a near-circular, 162- by 157-nautical-mile orbit. Spacecraft No. 10 was inserted into a 145- by 86-nautical-mile elliptical orbit. Slant range between the two vehicles was very close to the nominal 1000 miles. Major objective of the mission was achieved during the fourth revolution when the spacecraft rendezvoused with the GATV at 5 hours 23 minutes ground elapsed time and docked with it about 30 minutes later. More spacecraft propellant was used to achieve rendezvous than had been predicted, imposing constraints on the remainder of the mission and requiring the development of an alternate flight plan. As a result, several experiments were not completed, and another secondary objective - docking practice - was not attempted. To conserve fuel and permit remaining objectives to be met, the spacecraft remained docked with the GATV for about 39 hours. During this period, a bending mode test was conducted to determine the dynamics of the docked vehicles, standup extravehicular activties (EVA) were conducted, and several experiments were performed. The GATV primary and secondary propulsion systems were used for six maneuvers to put the docked spacecraft into position for rendezvous with the Gemini VIII GATV as a passive target. The spacecraft undocked at 44 hours 40 minutes ground elapsed time, separated from the GATV, and used its own thrusters to complete the second rendezvous some three hours later. At 48 hours and 42 minutes into the flight, a 39-minute period of umbilical EVA began, which included the retrieval of a micrometorite collection package from the Gemini VIII Agena. The hatch was opened a third time about an hour later to jettison extraneous equipment before reentry. After about three hours of stationkeeping, the spacecraft separated from the GATV. At 51 hours 39 minutes ground elapsed time, the crew performed a true anomaly-adjust maneuver to minimize reentry dispersions resulting from the retrofire maneuver. References: 2, 6, 26, 33,60.

Later Kamanin's group visits Darevskiy at MAP and reviews the status of Soyuz trainer completion. He promises to have them completed by the end of August. Finally Kamanin confronts Komarov over statements he made in Japan. Komarov admits telling the world press that the Soviet Union will, at the scheduled time, fly an automated spacecraft around the moon and return it to earth, to be followed by a dog flight, then a manned circumlunar flight. Kamanin has already had the Central Committee and Soviet Ministers calling him about this unauthorised disclosure. References: 376.

At 15:00 a major review is conducted, with Komarov, Khrunov, Gorbatko, Kamanin, and other VVS officer meeting with OKB-1 leaders Mishin, Tsybin, Severin, Alekseyev, Anokhin, and other engineers. Film is shown of the difficulties in the zero-G aircraft of cosmonauts attempting to exit from the 660 mm diameter hatch. In four sets of ten attempts, the cosmonaut was only to get out of the hatch half the time, and then only with acrobatic contortions - the inflated suit has a diameter of 650 mm, only 10 mm less than the hatch. Mishin finally concedes the point. But installation of the hatch in Soyuz s/n 3 and 4 is not possible - the spacecraft are essentially complete, and to add the hatch would delay their flight 6 to 8 months. Then Mishin makes the astounding assertion that Gorbatko and Khrunov are not adequately trained to be engineer-cosmonauts, and without this he will not allow them into space. He suggests OKB-1 engineers Anokhin and Yeliseyev instead. After outraged response, Severin finally sinks this suggestion by pointing out that no space suit has been prepared for Anokhin, and that it will take two to three months to make one. Kamanin is astounded that Mishin has pushed Anokhin all the way up to Smirnov and the VPK without even knowing he could not possibly fly due to this restriction. It again points out their poor management. Finally Mishin agrees that spacecraft s/n 5 and 6 and on will have 720 mm hatches. The ECS for the suits for those missions will have to be changed from a backpack configuration, with the equipment rearranged around the waist of the cosmonaut. The crews for the flight will be an experienced VVS pilot cosmonaut as commander, and (Kamanin realizes he may have to concede) a VVS engineer as flight engineer cosmonaut. They will have to complete training by 1 October 1966. References: 376.

Kamanin decides to smooth over matters with OKB-1. He calls Mishin, and then Tsybin, and agrees to begin processing of Anokhin, Yeliseyev, Volkov, and Kubasov as soon as he receives their personnel files and security clearances. Mishin promises to deliver the Soyuz mock-up of the Tu-104 zero-G aircraft soon - it slid from 20 July, then from 7 August. References: 376.

In turn, Factory 918 insisted on a final decision on Soyuz crews. They cannot build 16 of the custom-built spacesuits for all possible candidates for the flights (8 from VVS and 8 from OKB-1). It was therefore agreed that the commanders of the first two missions would be Komarov and Bykovsky, with Nikolayev and Gagarin as their backups. It was finally decided to assume that the other crew members would be either Khrunov and Gorbatko from the VVS, or Anokhin and Yeliseyev from OKB-1. References: 376.

During the spacecraft's stay in the final close-in orbit, the gravitational fields of the earth and the moon were expected to influence the orbital elements. The influence was verified by spacecraft tracking data, which showed that the perilune altitude varied with time. From an initial perilune altitude of 58 kilometers, the perilune decreased to 49 kilometers. At this time an orbit adjustment maneuver began an increase in the altitude, which was expected to reach a maximum after three months and then begin to decrease again. The spacecraft was expected to impact on the lunar surface about six months after the orbit adjustment.

During the photo-acquisition phase of the flight, August 18 to 29, Lunar Orbiter I photographed the 9 selected primary potential Apollo landing sites, including the one in which Surveyor I landed; 7 other potential Apollo landing sites; the east limb of the moon; and 11 areas on the far side of the moon. Lunar Orbiter I also took photos of the earth, giving man the first view of the earth from the vicinity of the moon (this particular view has been widely publicized). A total of 207 frames (sets of medium- and high-resolution pictures) were taken, 38 while the spacecraft was in initial orbit, the remainder while it was in the final close-in orbit. Lunar Orbiter I achieved its mission objectives, and, with the exception of the high-resolution camera, the performance of the photo subsystem and other spacecraft subsystems was outstanding. At the completion of the photo readouts, the spacecraft had responded to about 5,000 discrete commands from the earth and had made about 700 maneuvers.

Photographs obtained during the mission were assessed and screened by representatives of the Lunar Orbiter Project Office, U.S. Geological Survey, DOD mapping agencies, MSC, and Jet Propulsion Laboratory. The spacecraft was deliberately crashed into moon after the mission was completed. References: 2, 6, 16, 278.

Of six primary test objectives assigned to the mission, the objectives for the environmental control, electrical power, and communications subsystems were not completely satisfied. All other spacecraft test objectives were successfully accomplished. References: 2.
