In the summer of 1957 physicist Bob Brownlee attempted to 'contain' the blast effects of an atomic explosion from a device placed at the bottom of a 500 foot vertical shaft in the Nevada desert. A four-inch-thick steel plate weighing 'several hundred pounds' is placed over the hole (diameter not specified). This blew off as expected in the blast and was seen in films to depart the area at six times escape velocity . Brownlee never publicly challenged the Soviet's claim (to having launched the 1st Earth satellite.

Soyuz s/n 1 and 2 will be flown unpiloted by October 1966 Manned flights aboard Soyuz s/n 3, 4, 5, 6 will not take place until the first quarter of 1967. Later Mishin tours the cosmonaut training centre - the first time in his life he has visited the place. Mishin admires the new construction from Demin's balcony on the 11th floor of cosmonaut dormitory, then goes to Tereshkova's apartment on the seventh floor, and then Gagarin's apartment. Mishin insists on drinking a toast of cognac on each visit. Tyulin reveals this is a peace mission - they want to normalize relations and get on with cosmonaut training. At Fedosiya the auxiliary parachute of a Soyuz capsule failed to open during a drop test. Kamanin believes that the Soyuz parachute system is even worse than that of Vostok. His overall impression of the Soyuz is poor: the entire spacecraft looks unimpressive. The small dimensions of hatch, antiquated communication equipment, and inadequate emergency recovery systems are only the most noticeable of many discrepancies. If the automatic docking system does not function, then the entire Soviet space program will collapse in failure.

Lunar Orbiter I was launched from Cape Kennedy Launch Complex 13 at 3:26 p.m. EDT August 10 to photograph possible Apollo landing sites from lunar orbit. The Atlas-Agena D launch vehicle injected the spacecraft into its planned 90-hour trajectory to the moon. A midcourse correction maneuver was made at 8 p.m. the next day; a planned second midcourse maneuver was not necessary. A faultless deboost maneuver on August 14 achieved the desired initial elliptic orbit around the moon, and one week later the spacecraft was commanded to make a transfer maneuver to place it in a final close-in elliptic orbit of the moon.

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.

More detailed reviews within NASA showed there were still no obvious insurmountable problems that might block the plan. However North American was not too receptive to the idea. - Additional details.

Applications Technology Satellite that was to have been put into a geosynchronous transfer orbit, instead was left in a nearly-useless LEO orbit. ATS-4 included two cesium contact ion engines. Flight test objectives were to measure thrust and to examine electromagnetic compatibility with other spacecraft subsystems. The 5 cm diameter thrusters were designed to operate at 0.02 kW and provide about 89 microN thrust at about 6700 s specific impulse. The thrusters had the capability to operate at 5 setpoints from 18 to 89 microN. Thrusters were configured so they could be used for East-West station-keeping. Prior to launch, a 5 cm cesium thruster was life tested for 2245 hours at the 67 microN thrust level. However the Centaur upper stage did not achieve a second burn and the spacecraft remained attached to the Centaur in a 218 km by 760 km orbit. It was estimated that the pressure at these altitudes was between 10^-6 and 10^-8 Torr. Each of the two engines was tested on at least two occasions each over the throttling range. Combined test time of the two engines was about 10 hours over a 55 day period. The spacecraft re-entered the atmosphere on October 17, 1968. TheATS-4 flight was the first successful orbital test of an ion engine. There was no evidence of IPS electromagnetic interference related to spacecraft subsystems. Measured values of neutralizer emission current were much less than the ion beam current, implying inadequate neutralization. The spacecraft potential was about -132V which was much different than the anticipated value of about -40V.

An industrial research microsatellite built by Surrey Satellite Technology Ltd (SSTL) for Matra and CNES to carry out 'Little LEO' communications service experiments. Still operational in 2000. S80/T was designed to investigate the technical feasibility of using a constellation of small satellites placed in near-Earth orbit to provide global communications and position location using only hand-held terminals. S80/T was the first fully commercial application of the SSTL multi-mission, modular microsatellite platform developed at the University of Surrey. The same basic platform was also used for the Korean KITSAT-A microsatellite, which accompanied S80/T into orbit on the same launch. The S80/T mission was completed, from concept to launch, within one year and SSTL delivered the platform, associated groundstation equipment and would be providing operations support during the mission within a contract of less than £1M.
