The explosion of the RD5-6 400 kiloton warhead at Semiplatinsk proved the design of a lightweight thermonuclear warhead. Korolev began work in 1953 to develop a re-entry vehicle for this warhead.

Structural test flight, extreme dive and then pull up at Mach 1.3.

After a 15 hour 18 minute countdown G-26 number four finally left the pad. The boost phase was completed successfully; but then a guidance system malfunction prevented the cruise stage from separating from the booster until an altitude of 25 km was reached. However the autopilot successfully overcome drastic pitch oscillations created by the lofted trajectory, and the ramjets were successfully ignited. The stage cruised at Mach 2.93 for 280 km. However then the vehicle began drifting off course. The ground pilot banked, but the fuselage screened the airflow to the left ramjet intake, resulting in that engine flaming out. The vehicle lost speed and altitude, and the right engine flamed out a minute later. The missile was ordered into a terminal dive, impacting 425 km downrange.

Orange was a rocket-launched test of the W-39 warhead. Purpose was to measure the effects of high altitude nuclear explosions in order to design warheads for Nike-Zeus anti-ballistic missile system. The Hardtack Configuration Redstone shot the 3.8 megaton warhead to an altitude of 43 km.

The STG New Projects Panel (proposed by H. Kurt Strass in June) held its first meeting to discuss NASA's future manned space program. Present were Strass, Chairman, Alan B. Kehlet, William S. Augerson, Jack Funk, and other STG members. Strass summarized the philosophy behind NASA's proposed objective of a manned lunar landing : maximum utilization of existing technology in a series of carefully chosen projects, each of which would provide a firm basis for the next step and be a significant advance in its own right. - Additional details.

In the preceding months relations between the Soviet advisors and Chinese engineers had been strained by increasing Soviet secrecy. The Russians catch Chinese students at the Moscow Aviation Institute stealing restricted missile data. Finally Khrushchev declared the suspension of military assistance to China. All 1,343 Soviet specialists are withdrawn from the Fifth Academy in Beijing and return to Russia. They leave behind 343 uncompleted contracts. A total of 257 technical development projects were cancelled as a result.

Balloon; passively relayed TV and voice transmissions. Spacecraft engaged in practical applications and uses of space technology such as weather or communication (US Cat C).

Maximum Speed - 2851 kph. Maximum Altitude - 41605 m. Established a new altitude record for a manned vehicle of 136,500 feet. This topped Captain Kincheloe's record altitude of 126,200 feet attained on September 7, 1956, in the X-2 rocket research aircraft.

Joint flight with Vostok 3. Acquisition of experimental data on the possibility of establishing a direct link between two space ships; coordination of astronauts' operations; study of the effects of identical spaceflight conditions on the human organism. The launch of Popovich proceeds exactly on schedule, the spacecraft launching with 0.5 seconds of the planned time, entering orbit just a few kilometers away from Nikolayev in Vostok 3. Popovich had problems with his life support system, resulting in the cabin temperature dropping to 10 degrees Centigrade and the humidity to 35%. The cosmonaut still managed to conduct experiments, including taking colour motion pictures of the terminator between night and day and the cabin interior.

Despite the conditions, Popovich felt able to go for the full four days scheduled. But before the mission, Popovich had been briefed to tell ground control that he was 'observing thunderstorms' if he felt the motion sickness that had plagued Titov and needed to return on the next opportunity. Unfortunately he actually did report seeing thunderstorms over the Gulf of Mexico, and ground control took this as a request for an early return. He was ordered down a day early, landing within a few mintutes of Nikolayev. Only on the ground was it discovered that he was willing to go the full duration, and that ground control had thought he had given the code.

The readiness of two crews is certified (the prime crew of Volynov, Katys, and Yegorov and backup crew of Komarov, Feoktistov, and Sorokin). Korolev presses for Feoktistov to be included in the prime crew, citing his unequalled technical knowledge of the spacecraft. Kamanin and the VVS doctors oppose this, citing his poor medical condition which makes him uncertifiable for flight. A very heated discussion ensues, with the final decision to continue training all seven cosmonauts, with the first candidates for flight being Volynov, Katys, and Yegorov, with Komarov, Lazarev, and Sorokin being reserve cosmonauts. The question of Feoktistov's flight certification will be taken up by a special panel of physicians.

Maximum Speed - 5688 kph. Maximum Altitude - 24750 m.

On August 12 Kraft informed Low that December 20 was the day if they wanted to launch in daylight. With everyone agreeing to a daylight launch, the launch was planned for December 1 with a "built-in hold" until the 20th, which would have the effect of giving assurance of meeting the schedule. LTA (LM test article)-B was considered as a substitute; it had been through a dynamic test vehicle program, and all except Kotanchik agreed this would be a good substitute. Grumman suggested LTA-4 but Low decided on LTA-B.

During lunar module checkout activities at KSC, the LM-6 (for Apollo 12) guidance computer was removed and replaced because of an unexpected restart during panel revalidation.

Applications Technology Satellite; communications tests. Launch vehicle successfully put the payload into a geosynchronous transfer orbit. The spacecraft maneuvered into geostationary orbit at 108 degrees W. The purpose of this flight was to demonstrate North-South Stationkeeping of a geosynchronous satellite. ATS-5 was equipped with an ion engine package identical to that on ATS-4. Once in geosynchronous orbit the spacecraft could not be despun as planned, and thus the spacecraft gravity gradient stabilization could not be implemented. The spacecraft spin rate was about 76 revolutions per minute, and this caused an effective 4g acceleration on the cesium feed system. The high g-loading on the cesium feed system caused flooding of the discharge chamber, and normal operation of the thruster with ion beam extraction could not be performed. The IPS was instead be operated as a neutral plasma source, without high-voltage ion extraction, along with the wire neutralizer to examine spacecraft charging effects. The neutralizer was also operated by itself to provide electron injection for the spacecraft charging experiments. Positioned in geosynchronous orbit over the Americas at 105 deg W in 1969-1977; over the Americas at 70 deg W in 1977-1983. As of 1 September 2001 located at 15.48 deg E drifting at 2.807 deg W per day. As of 2007 Mar 10 located at 111.70E drifting at 2.819W degrees per day.

International Sun-Earth Explorer; later renamed the International Cometary Explorer. Measured interaction between solar wind and Earth; rendezvoused with comet Giacobini-Zinner September 11, 1985. After several passes through the Earth's magnetotail, with gravity assists from lunar flybys in March, April, September and October of 1983, a final close lunar flyby (119.4 km above the moon's surface) on December 22, 1983, ejected the spacecraft out of the Earth-Moon system and into a heliocentric orbit ahead of the Earth, on a trajectory intercepting that of Comet Giacobini-Zinner. A total of fifteen propulsive maneuvers (four of which were planned) and five lunar flybys were needed to carry out the transfer from the halo orbit to an escape trajectory from the earth-moon system into a heliocentric orbit. The primary scientific objective of ICE was to study the interaction between the solar wind and a cometary atmosphere. As planned, the spacecraft traversed the plasma tail of Comet Giacobini-Zinner on September 11, 1985, and made in situ measurements of particles, fields, and waves. It also transited between the Sun and Comet Halley in late March 1986, when other spacecraft (Giotto, Planet-A, MS-T5, VEGA) were also in the vicinity of Comet Halley on their comet rendezvous missions. ICE became the first spacecraft to directly investigate two comets. An update to the ICE mission was approved by NASA headquarters in 1991. It defined a Heliospheric mission for ICE consisting of investigations of coronal mass ejections in coordination with ground-based observations, continued cosmic ray studies, and special period observations such as when ICE and Ulysses are on the same solar radial line. As of January 1990, ICE was in a 355 day heliocentric orbit with an aphelion of 1.03 AU, a perihelion of 0.93 AU and an inclination of 0.1 degree. This will bring it back to the vicinity of the earth-moon system in August, 2014. Termination of operations of ISEE 3 was authorized May 5, 1997. - Additional details.

The launch vehicle delivered its H-10-3 third stage and the Telkom 1 payload into a 221 km x 35687 km x 7.0 degree geosynchronous transfer orbit 21 minutes after launch. Telkom 1 was owned by PT Telkomunikasi of Indonesia and was a successor to the Palapa series of satellites. Mass of Telkom 1 was 1700 kg in geosynchronous orbit after its on-board engine made the apogee burn. Stationed at 108 deg E. Positioned in geosynchronous orbit at 108 deg E in 1999. As of 3 September 2001 located at 107.98 deg E drifting at 0.011 deg W per day. As of 2007 Mar 11 located at 107.98E drifting at 0.014W degrees per day.

Originally to have launched September 2002; June 2003. A Russian newspaper report (Kommersant, 13 August) stated that Cosmos 2399 was a Neman (Yantar-4KS1M) imaging satellite, which used data relay satellites to return CCD imagery rather than physically recovering film. However some Western observors, when Cosmos 2399 raised its perigee on August 14 to 205 km and lowered the apogee to 330 km, believed this was more like the standard operational orbit for an Orlets-1 Don 17F12 film-return capsule imaging satellite. This seemed confirmed when debris was tracked around the satellite later on, which was then said to be due to a failed film capsule recovery attempt. Destroyed in orbit on December 9 after completing its mission.
