Council of Soviet Ministers (SM) Decree 'On renaming the Ministry of Armaments to the Ministry of Defence Industry' was issued.

President Eisenhower gave his approval to the plans for outer space exploration announced by Secretary of Defense Neil H. McElroy. The Advanced Research Projects Agency (ARPA) was to undertake several space projects including the launching of certain earth satellites and five space probes as a part of this country's contribution to the IGY program. The Air Force Ballistic Missile Division was authorized by ARPA to carry out three lunar probes with a Thor-Vanguard system, and lunar probes utilizing the Jupiter-C rocket were assigned to the Army Ballistic Missile Agency.

Dr. T. Keith Glennan, the NASA Administrator, provided instructions for the marking of vehicles launched for the NASA, including the Mercury spacecraft. He stated that policy would be to paint UNITED STATES in bold block form.

This was not the first time. The VVS hierarchy wants them all dismissed from the cosmonaut corps. Gagarin says that only Filatyev should be fired. Kamanin would prefer to see all three go, but cannot afford to lose 25% of his flight-ready cosmonauts. He would hope to at least keep Nelyubov, who was a candidate for the third or fourth Vostok flights, but did not perform well on the centrifuge.

The stage with payload remained in Earth orbit as Cosmos-27.

Test Series I on spacecraft 001 was completed at WSTF Propulsion Systems Development Facility. Vehicle and facility updating in progress consisted of activating the gimbal subsystem and installing a baffled injector and pneumatic engine propellant valve. The individual test operations were conducted satisfactorily, and data indicated that all subsystems operated normally. Total engine firing time was 765 seconds.

Gagarin is killed together with instructor pilot Sergin on a flight in a UTI MiG-15 trainer. Gagarin was being requalified as a jet pilot after being denied flight status by the leadership for a long time. At that time the mean flight hours between fatal accidents hours for Soviet jet fighters were: MiG-15, 18,440 hours; MiG-17, 11,460 hours; MiG-19, 4,475 hours; MiG-21, 4,422 hours; Su-7, 2,245 hours; Su-11, 2,100 hours. Gagarin's UTI MiG-15 s/n 612739 was built at the Vodokhod factory in Czechoslovakia and delivered on 19 March 1956. It had a 2100 hour airframe life, and had flown 1113 hours. It had two overhauls to date: one on 13 July 1962, after 13,834 'mil' hours, and the second on 30 March 1967, after 36,986 'mil' hours. It should have had a 500 hour life after the second overhaul, had flown only 62 hours since then, and had 438 hours left.

The group was selected to provide engineer to operate Vulkan space welding system.

Mars probe intended to enter Martian orbit and comprehensively photograph Mars, together with a landing probe.

Mars flyby 5 August 1969; returned 126 images of Martian surface. Mariner 7 was launched on a direct-ascent trajectory to Mars 31 days after Mariner 6. On 8 April 1969 a midcourse correction was made by firing the hydrazine moter for 7.6 seconds. On 8 May Mariner 7 was put on gyro control to avoid attitude control problems which were affecting Mariner 6. On 31 July telemetry from Mariner 7 was suddenly lost and the spacecraft was commanded to switch to the low-gain antenna. It was later successfully switched back to the high-gain antenna. It was thought that leaking gases, perhaps from the battery which later failed a few days before encounter, had caused the anomaly.

At 09:32:33 GMT on 2 August 1969 Mariner 7 bagan the far-encounter sequence involving imaging of Mars with the narrow angle camera. Over the next 57 hours, ending about 5 hours before closest approach, 93 images of Mars were taken and transmitted. The spacecraft was reprogrammed as a result of analysis of Mariner 6 images. The new sequence called for the spacecraft to go further south than originally planned, take more near-encounter pictures, and collect more scientific data on the lighted side of Mars. Data from the dark side of Mars were to be transmitted directly back to Earth but there would be no room on the digital recorder for backup due to the added dayside data. At closest approach, 05:00:49 GMT on 5 August, Mariner 7 was 3430 km above the martian surface. Over this period, 33 near-encounter images were taken. About 19 minutes after the flyby, the spacecraft went behind Mars and emerged roughly 30 minutes later. X-band occultation data were taken during the entrance and exit phases. Science and imaging data were played back and transmitted over the next few days. The spacecraft was then returned to cruise mode which included engineering and communications tests, star photography TV tests, and UV scans of the Milky Way and an area containing comet 1969-B. Periodic tracking of the spacecraft in its heliocentric orbit was also done.

Science Results

The total data return for Mariners 6 and 7 was 800 million bits. Mariner 7 returned 93 far and 33 near encounter images. Close-ups from the near encounter phases covered 20% of the surface. The spacecraft instruments measured UV and IR emissions and radio refractivity of the Martian atmosphere. Images showed the surface of Mars to be very different from that of the Moon, in some contrast to the results from Mariner 4. The south polar cap was identified as being composed predominantly of carbon dioxide. Atmospheric surface pressure was estimated at between 6 and 7 mb. Radio science refined estimates of the mass, radius and shape of Mars.

Venus atmospheric probe. The spacecraft took 117 days to reach Venus, entering the atmosphere on 22 July 1972. Descent speed was reduced from 41,696 km/hr to about 900 km/hr by aerobraking. The 2.5 meter diameter parachute opened at an altitude of 60 km, and a refrigeration system was used to cool the interior components. Venera 8 transmitted data during the descent and continued to send back data for 50 minutes after landing. The probe confirmed the earlier data on the high Venus surface temperature and pressure returned by Venera 7, and also measured the light level as being suitable for surface photography, finding it to be similar to the amount of light on Earth on an overcast day.

The group was selected to provide flight engineers for planned Almaz military space station missions.

Phobos 2 operated nominally throughout its cruise and entered Mars orbit on January 29, 1989. Contact with the vehicle was lost on March 27, 1989 shortly before the final phase of the mission during which the spacecraft was to approach within 50 meters of Phobos' surface and release its two landers. The cause of the failure was determined to be a malfunction of the on-board computer.

The second X-43 launch incorporated modifications to the first flight vehicle, including an upgraded control system, redesigned autopilot, off-loaded rocket motor, and improved analytical models. The second flight was launched at 12,200 m instead of the 7600 m altitude of the failed first launch to reduce transonic aerodynamic loads and improve structural and control system margins. An offloaded Orion 50S solid rocket motor reduced maximum dynamic pressure during the flight.
