  • Decision to withhold R-12 and nuclear warhead drawing package from China over Sidewinder affair - . Nation: China. Related Persons: Khrushchev; Tsien. Spacecraft: Project 581. The Soviet Central Committee advises China it will not provide prototype or drawings of atomic bombs as agreed previously. Khrushchev promised China that he would provide the drawing package for the R-12 IRBM as soon as testing was completed. However then came the affair of the Sidewinder. At the end of 1958 or early 1959 a complete missile fell into the hands of the Chinese. They promised to provide it to the Russians, but then dragged their feet. They were finally told in February 1959 that unless they provided the Sidewinder, they would not be given the R-12 package. The missile was finally delivered but it was found that the key crystal in the infrared homing sensor was missing. The Chinese had also been caught disassembling a P-15 cruise missile at a training facility in China. It had taken the Russian trainers two days to get it reassembled correctly. Therefore on June 20 1959 the decision was taken not to transfer the R-12 or the promised nuclear warhead design to China.

    The Soviets created a new design bureau to copy the Sidewinder. Fabrication of the crystal for the infrared sensor was the main obstacle. The initial production batches had a 99% rejection rate. A state commission was set up to get to the bottom of the problem, but couldn’t find a solution. The main problem seemed to be low-quality ore provided by the mines.

Korolev, Tyulin, and Rudenko left Tyuratam aboard an An-12, followed by 60 others (cosmonauts, officers, engineers) aboard an An-10. General Goreglyad requests that 'extraneous' staff remain in Kuibyshev, while the rest will proceed on to Moscow with Bykovskiy and Tereshkova. The aircraft arrive at 11:30 in Kuibyshev, then go to the debriefing building on the Volga river. There the debriefing of the two cosmonauts began at 13:00. After the debriefings, in the evening, Korolev took the cosmonauts for a trip on the Volga. Kamanin was infuriated - partying would ruin the post-flight medical tracking.

  • Gemini sled test No. 2 at China Lake. - . Nation: USA. Program: Gemini. Spacecraft: Gemini; Gemini Ejection. Sled test No. 2, the first dynamic dual-ejection test of the Gemini escape system, was run at China Lake. Both seats ejected and all systems functioned properly. The test was scheduled to be rerun, however, because the sled failed to attain high enough velocity. The purpose of sled tests in the ejection seat development program was to simulate various high-altitude abort situations. Sled test No. 3 was successfully run on August 9. Further tests were delayed while the ejection system was being redesigned. A modified egress kit was tested in two dummy drops on December 12, with no problems indicated. Gemini Project Office directed McDonnell to proceed with plans for the next sled test. Developmental sled testing on the escape system, incorporating the redesigned egress kit and a soft survival pack, resumed on January 16, 1964, with test No. 4; all systems functioned normally. Test No. 5, the planned repetition of test No. 2, brought developmental sled testing to an end on February 7.

  • Soyuz 11 Day 15 - . Nation: USSR. Related Persons: Dobrovolsky; Patsayev; Volkov; Gorbatko. Program: Salyut. Flight: Soyuz 11. Spacecraft: Salyut 1. The Soyuz 11 crew completes their 1000th revolution of the earth. Gorbatko jokes that they are 'go for 2000' but the crew is not enthusiastic. Kamanin does not believe they have more than 10 or 11 days endurance left in them. Clear problems exist: the Penguin training suits do not adequately replace gravitational effects (they have suffered torn elastic bands); the measured lung capacity of the crews has declined from 300 on the first day of the flight to 200 now; use of the treadmill caused the whole station to vibrate alarmingly and was discontinued (the solar panels flapped, the propellants sloshed in the tanks, and the noise of the track couldn't be kept out of the rest areas). The weather is very poor in the prime recovery area for the last two days - 20-25 m/s wind - dangerous for landing.
