An MSC meeting selected a Flight Operations Directorate position on basic factors of the first lunar landing mission phase and initiated a plan by which the Directorate would inform other organizations of the factors and the operational capabilities of combining them into alternate lunar surface mission plans.

Flight Operations Director Christopher C. Kraft, Jr., conducted the discussion, with Rodney G. Rose, Carl Kovitz, Morris V. Jenkins, William E. Platt, James E. Hannigan, Bruce H. Walton, and William L. Davidson participating.

The major factors (philosophy) identified at the meeting were:

• "The astronauts should be provided with an extravehicular (EVA) timeline framework and objectives and then be given real time control of their own activities. This approach should better accommodate the first lunar surface unknowns than if rigorous activity control were attempted from earth."
• "The LM should always be in a position to get back into lunar orbit in the minimum time. Specifically the merits and feasibility of maintaining the LM platform powered up and aligned should be evaluated. Any other LM systems requiring start up time after powering down should be identified."
• "The constraints affecting the minimum time required to turn around and launch after LM landing and the time line should be determined. This time was estimated to two CSM orbits. The effects of Manned Space Flight Network (MSFN) support should be considered."
• The first EVA should be allocated to LM post landing inspection, immediate lunar sample collection, lunar environment familiarization, photographic documentation, and astronaut exploration prerogatives. Any second EVA would include deployment of ALSEP (Apollo Lunar Surface Experiments Package) and a more systematic geological survey. Therefore, a mission nominally planned for only one EVA would not have to include an ALSEP in the payload. Any flight operations benefits resulting from deletion of the ALSEP weight and deployment operations (such as replacing weight with more fuel) must be determined."

Crews are in training for Voskhod, Soyuz, Lunar L-1, Almaz, and 7K-VI missions. There will be 100 cosmonauts in training by February. Meanwhile the Americans have conducted 10 manned flights since the last Soviet manned flight in March 1965. The cosmonauts want Kamanin to be training 8 crews for L-1 translunar flights, but he only has 4 in training. He doesn't think it is worth to train more, since if one successful L-1 flight is conducted before the 50th Anniversary of the Soviet Union in November 1957, all subsequent flights will be cancelled.

Apollo Program Director Samuel C. Phillips told NASA Associate Administrator for Manned Space Flight George E. Mueller that studies had been completed on the use of "direct translunar injection" (launch directly into a trajectory to the moon) as a mode of operation for lunar landing missions. The principal advantages would be potential payload increases and elimination of the S-IVB stage restart requirement. The disadvantage was that there would be no usable launch windows for about half of each year and a reduced number of windows for the remainder of the year. Phillips was confident the launch vehicle would have adequate payload capability, since Saturn V performance continued to exceed spacecraft requirements. Confidence in successful S-IVB restarts was also high. For the lunar missions, therefore, direct launch was considered as a fall-back position and the effort was concentrating on the parking orbit mode.

Space Systems Division selected the Hughes Aircraft Company as the contractor to proceed with research and development of the experimental communications satellite for the U. S. military services. With a target price of $23.5 million, the contract called for design, engineering, assembly, and testing of what became the Tactical Communication Satellite (TACSAT I).

Spacecraft engaged in practical applications and uses of space technology such as weather or communication (US Cat C). Positioned in geosynchronous orbit over the Pacific Ocean at 174 deg E in 1967-1969; over the Pacific Ocean 162-170 deg E in 1969-1970; over the Pacific Ocean 150-160 deg E in 1970-1975 As of 7 August 2001 located at 48.66 deg E drifting at 0.413 deg W per day. As of 2007 Mar 8 located at 63.48W drifting at 0.357W degrees per day.

The NASA Western Support Office, Santa Monica, Calif., reported two accidents at North American plants, with no personal injuries:

• Apollo CM 2S-1 - being hoisted into a cradled position at North American Aviation's Space and Information Systems Division, Downey, Calif. - was dropped 1.8 meters onto a concrete floor Jan. 12. The first report was that the CM apparently suffered considerable damage.
• The S-II-5 interstage received possible structural damage when the protective metal roof covering of a handling fixture was struck during the swing opening of the six-story east door of Station 9 at the Seal Beach plant. The structural connections of the handling fixture to the interstage indicated damage. The S-II-5 interstage had been improperly parked within the swing opening of the east door.

Launched from Cape Canaveral, a Titan IIIC (Vehicle #13) space booster lifted eight 100-pound military communications satellites into synchronous orbits 21,000 miles above the equator. The satellites, together with the seven placed in orbit on 16 June 1966, formed the Initial Defense Satellite Communication System (IDSCS). Space craft engaged in investigation of spaceflight techniques and technology (US Cat A).

The Saturn 503 S-IVB stage exploded and was destroyed at the Douglas Sacramento, Calif., Test Facility at 4:25 p.m. PST during a countdown. The exercise had progressed to 10 seconds before simulated launch (about 8 minutes before S-IVB ignition) when the explosion occurred. Additional Details: here....

Tsien was overthrown by the 916 (Mao) Clique. Ye Zhengguang, a missile engineer, with the approval off Zhou En Lai and Marshall Nie, confronts Tsien and removes him from his post as head of the Seventh Ministry. Minister of Machine Building Wang Bingzhang was also deposed. However Tsien was protected by the leadership, made a 'Vice Minister', and claimed he supports the coup. Wang refused to cooperate and would not hand over the chops of his office to the 916 Clique.

At a NASA Hq briefing, Associate Administrator for Manned Space Flight George E. Mueller stated that NASA planned to form an 'embryonic space station' in 1968-69 by clustering four AAP payloads launched at different times. The first mission would be the launch of a manned spacecraft followed several days later by a spent S-IVB stage converted into an OWS. After the two spacecraft had docked, the crew would enter the Workshop through an airlock. Twenty-eight days later they would passivate the OWS and return to Earth in their spacecraft. In three to six months, a second manned spacecraft would be launched on a 56-day mission to deliver a resupply module to the OWS and to rendezvous with an unmanned ATM, the fourth and last launch of the series. The cluster would be joined together using the multiple docking adapter. Emphasizing the importance of manning the ATM, Mueller said that 'if there is one thing the scientific community is agreed on it is that when you want to have a major telescope instrument in space it needs to be manned.'

Representatives of 62 nations signed the space law treaty, "Treaty on Principles Covering the Activities of the States in the Exploration and Use of Outer Space, Including the Moon and Other Celestial Bodies," at separate ceremonies in Washington, London, and Moscow. The treaty, which limited military activities in space, had been agreed upon by the U.S. and U.S.S.R. December 8, 1966, and unanimously approved by the United Nations General Assembly December 19. It was to become effective when ratified by the U.S., U.S.S.R., United Kingdom, and two other countries.

The first manned flight of the Apollo CSM, the Apollo C category mission, was planned for the last quarter of 1966. Numerous problems with the Apollo Block I spacecraft resulted in a flight delay to February 1967. The crew of Virgil I. Grissom, Edward H. White II, and Roger B. Chaffee, was killed in a fire while testing their capsule on the pad on 27 January 1967, still weeks away from launch. The designation AS-204 was used by NASA for the flight at the time; the designation Apollo 1 was applied retroactively at the request of Grissom's widow.

Funeral services were held for the Apollo crewmen who died in the January 27 spacecraft 012 (Apollo 204 mission) flash fire at Cape Kennedy. All three were buried with full military honors: Virgil I. Grissom (Lt. Col., USAF), and Roger B. Chaffee (Lt. Cdr., USN), in Arlington, Va., National Cemetery; and Edward H. White II (Lt. Col., USAF), at West Point, N.Y. Memorial services had been held in Houston January 29 and 30.

A TWX from NASA Headquarters to MSC, MSFC, and KSC ordered checkout and launch preparation of AS-501 to proceed as planned, except that the CM would not be pressurized in an oxygen environment pending further direction. If AS-501 support, facility, or work force should conflict with the activities of the AS-204 Review Board, the Board would be given priority.

Soviet government approves plan to land cosmonaut on moon by end 1968. N-1 test plan approved, envisioning third quarter 1967 as beginning of flight hardware construction. Fall-back project would be manned circumlunar mission. First manned L1 mission imagined as early as June 1967. First N1 launch by March 1968.

The following is the schedule set be decree for the L1 and L3 projects:

After the self-destruction of the first Soyuz 7K-OK on re-entry, and the loss of the second one on the pad fire in December, the state commission ruled that the third 7K-OK model would be flown unpiloted on a solo mission. If this was successful then the fourth and fifth Soyuz would be flown on a manned docking mission. Once in orbit Cosmos 140 experienced attitude control problems due to a faulty star sensor resulting in excessive fuel consumption. The spacecraft couldn't keep the required orientation towards the sun to keep the solar panels illuminated, and the batteries discharged. Despite all of these problems the spacecraft remained controllable. An attempted manoeuvre on the 22nd revolution still showed problems with the control system. It malfunctioned yet again during retrofire, leading to a steeper than planned uncontrolled ballistic re-entry. The re-entry capsule itself had depressurised on separation from the service module due to a fault in the base of the capsule. A 300 mm hole burned through in the heat shield during re-entry. Although such events would have been lethal to any human occupants, the capsule's recovery systems operated and the capsule crashed through the ice of the frozen Aral Sea, 3 km from shore and 500 kilometres short of the intended landing zone. The spacecraft finally sank in 10 meters of water and had to be retrieved by divers. Still, the mission was deemed 'good enough' for the next mission to be a manned two-craft docking and crew transfer space spectacular. Mishin and Kamanin felt that a human crew could have sorted out the problems. They were also under intense pressure to achieve a manned circumlunar flight before the 50th Anniversary of the Soviet Revolution in October.

The Board of Inquiry into the January 20 S-IVB-503 explosion at the Douglas Sacramento Test Facility identified the probable cause as the failure of a pressure vessel made with titanium-alloy parent-metal fusion welded with commercially pure titanium. The combination, which was in violation of specifications, formed a titanium hydride intermetallic that induced embrittling in the weld nugget, thus significantly degrading the capabilities of a weldment to withstand sustained pressure loads. The Board recommended pressure limitations for titanium-alloy pressure vessels.

The Chief Designer of OKB-1, Vasiliy Pavlovich Mishin, strongly disagreed with the Zvezda design. In the place of Kozlov's 7K-VI Mishin proposed an OIS consisting of a separately-launched orbital block and a transport Soyuz. This was the exact same concept as Kozlov's cancelled Soyuz-R system, but using Kaliningrad spacecraft in the place of Samara spacecraft.

NASA agrees to fly four Deparment of Defense experiments planned for MOL on Apollo Applications mission instead (later Skylab). These included an inflatable airlock experiment. NASA also provided the Gemini 6 capsule to the Air Force for MOL crew training.

The Institute of Medical-Biological Problems (IMBP) and the Zvezda design bureau (designer of the ejection seat, space suits, and environmental control system for the Vostok spacecraft) became partners with OKB-1 in developing the SOZh closed-loop environemental control system. An earth-based simulator - the Earth Experimental Complex (NEK) was built. V Ulibishev, G Manovtsev, and A Bozhko spent an entire year in this closed-environment test unit beginning on 5 March 1967. An analogous US experiment was conducted for only 90 days in July-September 1970.

The second SV-5D Precision Recovery Including Maneuvering Reentry (PRIME) lifting body was successfully launched from Vandenberg by an Atlas booster. Although the SV-5D was not recovered, its on-board sensors provided excellent data on the effects of reentry. This was also the first spacecraft to perform cross-range maneuvers during reentry. The X-23A SV-5D lifting body vehicle demonstrated a 1055 km cross-range manoeuvre, but again air snatch failed.

NASA Associate Administrator for Manned Space Flight George E. Mueller stated that the February completion of MSFC studies of the Saturn V launch vehicle's payload and structural capability would permit an official revision of the payload from 43,100 kilograms to 44,500 kilograms; the CM weight would be revised from 5,000 to 5,400 kilograms; and the LM from 13,600 to 14,500.

Space Systems Division awarded the Space and Reentry Systems Division of Philco-Ford Corporation a contract for the development and production of the spacecraft for the United Kingdom's Skynet. Two spin-stabilized, synchronous, station-keeping satellites were to be produced. Thrust Augmented Thor/Delta boosters and launch services would be procured from NASA by Space Systems Division to place the satellite into orbit. When operational, both Skynet satellites would form part of the larger United States Initial Defense Satellite Communication System Program (IDSCS).

Protoype Soyuz 7K-L1P launched by Proton into planned highly elliptical earth orbit. The first flight four-stage Proton rocket began assembly on 21 November 1966, with mechanical assembly completed by 29 November. Electrical connections and tests were completed by 4 December 1966. Due to New Year's holidays work did not resume until 28 January 1967. By 28 February the fully assembled booster / spacecraft unit was completed in the MIK, including the 7K-L1P boilerplate spacecraft. The launch tower was added on 2 March 1967 and the system was declared ready for launch. A serious potential problem during preparations was the discovery that fuel gases could lead to pump cavitation at the turbine exits. Tests on the ground showed that the problem was not the fuel itself, but in the monitoring equipment. The launch vehicle and Block D stage functioned correctly and put the spacecraft into a translunar trajectory. The spacecraft was not aimed at the moon, did not have a heat shield for reentry, and no recovery was planned or attempted. A successful launch that created false confidence just before the string of failures that would follow.

Titov visits Kamanin on leave from test pilot duties at Vladimirovka. Titov will spend a year training as a test pilot on MiG-21, Su-7, and Su-9 aircraft. He flies well, and has matured and changed for the better over the last two years. Kamanin has talked to him 3 or 4 times about his future plans. Titov has bound his future with the Spiral spaceplane programme. Additional Details: here....

UR-500K/L1 project will consist of three phases. Phase I will be dedicated to development of the Block D translunar stage, using prototype, incomplete L1 spacecraft. Phase II will conduct lunar flybys with complete but unmanned L1 spacecraft. Phase III will fly Soviet cosmonauts around the moon. The N1/L3 project will consist of five phases. Phase I will use the N1 and the 7K-L1A spacecraft. This will be used primarily to test out the Block G translunar and Block D lunar orbit insertion stages, but will also conduct lunar flybys, returning photographs of the lunar surface to the earth. Phase II will use N1's to fly L3 spacecraft with an unpiloted LOK lunar orbiter and an unpiloted LK lunar lander. Phase III, the first manned missions, will use N1's to fly L3 spacecraft with a piloted LOK lunar orbiter and an unpiloted LK lunar lander. Phase IV will fly a piloted LOK lunar orbiter and an unpiloted LK lunar lander, that will be landed on the lunar surface. In Phase V N1-L3 number 10L is to launch the first manned landing on the moon in September 1968. N1-L3 numbers 11L and 12L were back-ups, in the event any of the planned earlier missions failed.

The Soyuz 1/2 crews had planned to depart for Baikonur on 30 March, but Mishin wants to push this forward to the night of 17/18 March. This disrupts all of Kamanin's training plans and shows the poor planning and work of Mishin and his followers. A Soyuz state commission is held. Kamanin doesn't trust Mishin. The spacecraft is unreliable and incompletely tested. But it is decided all the conditions exist for a launch of the mission on 20-25 April. The question of Gagarin flying on the mission is brought up. The Communist Party says he is too valuable to risk on further spaceflights. Kamanin is against making him a living 'museum exhibit'. Smirnov agrees to raise the matter with the Politburo.

NASA announced it would use the Apollo-Saturn 204 launch vehicle to launch the first lunar module on its unmanned test flight. Since the 204 vehicle was prepared and was not damaged in the Apollo 204 fire in January, it would be used instead of the originally planned AS-206.

Weight growth of the MOL station forced the Air Force to consider upgrading of the Titan booster. Stretching of the booster core or use of 156 inch solid rocket motors was considered. The Air Force also dithered as to whether to compete the Titan booster contract. Eight months were spent making the decision, and at the end of it all the first manned MOL flight was delayed to 1970 and the projected total cost increased from $ 1.5 billion to $ 2.2 billion.

The cosmonauts have given up on further training at Baikonur due to the incomplete state of the spacecraft and returned to Moscow. Kamanin wanted to confront Mishin on the issue - this was all his fault, six days wasted - but Mishin never even showed up on the plane for the flight to Baikonur.

Kerimov argued with Mishin that without any logical reason his demand that the cosmonauts go to the cosmodrome for training has disrupted their preparation schedule. Later Kamanin met with Gagarin, Leonov, Volynov, and Makarov, all selected as pilots for L1 lunar flybys. The L1 flight scenario was still open. Variant 1 would involve launch of two spacecraft, with transfer of one to two crew to the translunar spacecraft in earth orbit. Variant 2 would be a direct flight to the moon. Additional Details: here....

A State Commission is held on the impending L1 translunar flights. A major issue is the L1 tracking/recovery radio beacon and the Zarya-3 deep space communications system. Launches of prototype L1P spacecraft are planned for April and May, with the first all-up L1 in June. All commission members are confident a Soviet man will the first around the moon by the end of the year. The State Commission also considers the pending Soyuz 1 / Soyuz 2 flight.

Positioned in geosynchronous orbit over the Atlantic Ocean at 15 deg W in 1967-1971; over the Atlantic Ocean at 35 deg W in 1972; over the Atlantic Ocean at 15 deg W in 1973. As of 22 August 2001 was at 6.75 deg W drifting at 0.037 deg W per day. As of 2005 Dec 5 located at 13.34E drifting at 0.188W degrees per day. Spacecraft engaged in practical applications and uses of space technology such as weather or communication (US Cat C).

NASA Hq. Office of Manned Space Flight informed KSC, MSFC, and MSC of approved designations for Apollo and Apollo Applications missions:

1. all Apollo missions would be numbered sequentially in the order flown, with the next mission to be designated Apollo 4, the following one Apollo 5, etc., and
2. the Apollo Applications missions would be designated sequentially as AAP-1, AAP-2, etc. The number designations would not differentiate between manned and unmanned or uprated Saturn I and Saturn V missions. Additional Details: here....

Kamanin examines maps of the moon, executed at scales of 1:5,000,000 and 1:10,000,000. 2000 are to be printed for use by the cosmonauts in preparation for the Soviet lunar landings. Mishin doesn't see the point - he is very aggressively anti-pilot for his lunar spacecraft.

Ustinov reviews the cosmonauts. Kamanin urges that a manual docking be allowed on the Soyuz 1/2 mission - he had argued the same point with Korolev before his death. Komarov say he can accomplish a manual docking from 350 km range (once the Igla automatic system has brought him there from 23 km range). There follows a discussion of an all-female flight. Four female cosmonauts would be assigned to the mission, and Kamanin would need 5 to 6 months to complete there training. The mission is designated 'Voskhod-6'.

Ye-8 proposed with a life support system to allow a lunar cosmonaut to remain on the moon until a rescue expedition could be launched with an LKR. As an alternative to a 2-launch scenario, the possibility was raised of the Ye-8 being equipped with a life support system to allow the cosmonaut to remain on the moon until a rescue expedition could be launched with an LKR. But Ye-8 chief designer Babakin said at that time that this was not feasible (Mishin Diaries 2-60; 2-62).

Technicians from MSC's Landing and Recovery Division conducted demonstrations of land- landing at Ft. Hood, Texas, on 6, 11, and 12 April. The demonstrations were part of MSC's effort to develop an advanced system to provide a land-landing capability for the Apollo Applications Program, an improved launch abort situation, and reduced horizontal velocities for water landings.

The Apollo 204 Review Board transmitted its final formal report on the fire to the NASA Administrator. The Board noted that the reliability of the CM and the entire system involved in its operation was a requirement common to both safety and mission success. It followed that protection from fire as a hazard required much more than quick egress. The risk of fire was only one factor pertaining to CM reliability that must receive adequate consideration. Design features and operating procedures intended to reduce the fire risk must not introduce other serious risks to mission success and safety. Additional Details: here....

Joseph F. Shea, MSC Apollo Spacecraft Program Office Manager, was appointed NASA Deputy Associate Administrator for Manned Space Flight, with responsibility for technical aspects of the program.

George M. Low, MSC Deputy Director, would succeed Shea as ASPO Manager. Changes were to be effective April 10.

Protoype Soyuz 7K-L1 manned circumlunar spacecraft. There are high winds for the L1 launch, 15-17 m/s. The official limit is 20 m/s, but Chelomei wants to scrub the launch if winds go over 15 m/s. Nevertheless the launch proceeds in 17-18 m/s winds and the L1 reached earth orbit. However the Block D translunar injection stage failed to fire (ullage rockets, which had to fire to settle propellants in tanks before main engine fired, were jettisoned prematurely). The failure is blamed on Mishin and has Tsybin seething in anger. Mishin is disorganised and has made many mistakes. Spacecraft burned up two days later when orbit decayed. Later in the day comes the news the RTS has to be replaced on one of the Soyuz 1/2 spacecraft. This will have a 3 to 4 day schedule impact, and push the launch back to 15-20 April. The crews arrive the same day for the upcoming Soyuz launch.

The cosmonauts began work at 10:30 in the morning, and didn't complete work until 23:30 at night. They spent 16 hours working on Cosmonaut's Day, due to the criminally chaotic performance of TsKBEM. The cosmonauts have to train simultaneously for the Soyuz and L1 missions. Kamanin warns Kerimov about the unacceptable situation. Grechko arrives to head the state commission. The launch of Soyuz 1 is set for 24-25 April - there will be only eight days to fix all of the problems. The energy and optimism of Korolev is sorely missed. Mishin was a poor deputy, and a worse leader - his constant mistakes and stupidity delay work and aggravate people. The cosmonauts have to keep in shape by playing tennis, but there is only one court at Tyuratam - a second court is to be built eventually (!)

The cosmonauts are completely trained, ready for launch at any time with four hours notice. Then Mishin calls Ustinov and tells him that their training is what is holding up the Soyuz 1 launch! From the point of view of the military quality assurance inspectors, there are 100 unresolved discrepancies on Soyuz 1 - the spacecraft is a piece of shit.

The Soyuz 2 crew trains from 15:00 to 20:00 - they had to wait due to problems with the spacecraft, but then the training went all right. The argument continues on whether to do an automatic or a manual docking. The design bureau wants to use the Igla automatic system; the cosmonauts want to do it manually. They have done 800 dockings in the simulator, so they should know best, in Kamanin's opinion. They want to let the automatic system take the spacecraft up to 50 to 70 m from the target, then use manual maneuvering to proceed to dock. The number two valve on the Soyuz 1 spacecraft's nitrogen tank was inadvertently opened during preparation. It was said not to be serious, but the problems are getting on everyone's nerves.

A fire broke out in the Bell Aerosystems Test Facility, Wheatfield, N.Y., at 2:30 a.m. April 20. Early analysis indicated the fire was started by overpressurization of the ascent engine's propellant- conditioning system, which caused the system relief valve to dump propellant into an overflow bucket. The bucket in turn overflowed and propellant spilled onto the floor, coming into contact with a highly oxidized steel grating. Contact was believed to have initiated combustion and subsequently an intense, short-duration fire. Additional Details: here....

150 people attend. The readiness of the spacecraft and launch vehicles are confirmed. The final responsibilities and schedule are approved. Everything is go. Afterwards there is a meeting with Mishin. He is mainly worried about two things that could cause them to scrub the launch of the second Soyuz: a failure of the Igla automatic docking system or the solar panels on Soyuz 1.

The third and last SV-5D Precision Recovery Including Maneuvering Entry (PRIME) flight vehicle, essentially a small maneuverahle reentry spacecraft, successfully performed cross-range maneuvers after being launched from Vandenberg on an Atlas booster. The series of three flights was so successful in demonstrating that a maneuverable spacecraft could survive reentry that the planned fourth flight test was cancelled. The full design 1145 km cross range was demonstrated, and the X-23A SV-5D lifting body vehicle was successfully snatched at 3700 m altitude, 8 km from the target point. With this success the rest of the project was cancelled, and the two remaining unflown X-22A's were sent to the USAF Museum at Wright Patterson Air Force Base.

The final flight of Squadron 20 Minuteman III missiles was turned over to SAC. This brought the strength of the 341st Strategic Missile Wing at Malmstrom AFB to 200 Minuteman missiles. The formal turnover on 3 May completed the deployment of the programmed 1,000 Minuteman missile launchers.

Space disaster that put back Soviet lunar program 18 months. Soyuz 1 as active spacecraft was launched first. Soyuz 2, with a 3 man crew would launch the following day, with 2 cosmonauts spacewalking to Soyuz 1. However immediately after orbital insertion Komarov's problems started. One of the solar panels failed to deploy, staying wrapped around the service module. Although only receiving half of the planned solar power, an attempt was made to manoeuvre the spacecraft. This failed because of interference of the reaction control system exhaust with the ion flow sensors that were one of the Soyuz' main methods of orientation. Additional Details: here....

Russian pilot cosmonaut 1960-1967. First person to die during spaceflight when the parachute lines of Soyuz 1 tangled and it crashed to earth. Cosmonaut training March 1960 - 3 April 1961. Call sign: Rubin (Ruby). 2 spaceflights, 2.1 days in space. Flew to orbit on Voskhod (1964), Soyuz 1.

The decision was made to bring Komarov back due to an undeployed solar panel which reduced electrical power and blocked orientation sensors. Re-entry was successful and the drag chute deployed. However due to a flaw during manufacture, the parachute compartment housing was too rough and the main parachute would not deploy. Komarov released the reserve chute, but it became tangled with the drag chute. The descent module crashed into a field near Orenburg at 03:24 GMT. Additional Details: here....

Ustinov convened the commission at noon. The work was to be completed by 15 May, and the final report issued by 25 May. The members of the commission would be Ustinov, Smirnov, Serbin, Afanasyev, the Chief Designers, and Gagarin. 22 members would work in seven subcommittees that would:

• Investigate design and test of the spacecraft structures
• Investigate design and test of the landing and parachute systems
• Investigate design and test of the orientation and guidance systems
• Study the performance of the tracking, communications, and flight ground control systems
• Investigate design and test of the launch system
• Analyse the contents of the Mir-3 flight data recorder, telemetry, and space-to-earth communications
• Review the design and as-built documentation for the spacecraft, subsystems, training program, flight plan, and the on-board flight log

Two new and heavier Vela Nuclear Detection Satellites and three scientific satellites were placed in orbit by a Titan IIIC (Vehicle #10) launched from Cape Canaveral. The two Vela satellites joined six other Vela spacecraft already on sentry duty 69,000 miles above the earth. Space craft engaged in investigation of spaceflight techniques and technology (US Cat A).

Review of progress on the L1 trainer MN-17, consisting of the SA and NO of the spacecraft It was built by the Factory Brigade headed by Darevskiy and was finished three to four weeks ago. But there is still the question of the cosmonauts conducting autonomous navigation. Tyulin and Mishin promised a solution long ago, but nothing has been delivered to date.

The Air Force Manned Orbiting Laboratory Systems Program Office requested that MSC present a briefing to selected office and contractor personnel on NASA's progress in safety studies and tests associated with fire hazards aboard manned space vehicles. Information was requested for the MOL program to help formulate studies and activities that would not duplicate MSC efforts. The briefing was given at MSC May 10.

Directions had been prepared to designate mission AS-501 formally as Apollo 4, AS-204/LM-1 as Apollo 5, and AS-502 as Apollo 6, NASA Apollo Program Director Samuel C. Phillips informed Associate Administrator for Manned Space Flight George E. Mueller. Phillips said he thought it was the right time to start using the designations in official releases and appropriate internal documentation. Mueller concurred.

Revised Apollo and AAP-integrated program plan shows CSM would be available to support the first four AAP launches. Some significant features of a revised Apollo and AAP-integrated program plan were: CSM would be available to support the first four AAP launches; AAP-1/ AAP-2 in early 1969 were to accomplish OWS objectives; AAP-3/AAP-4 in mid-1969 were to accomplish the 56-day ATM objectives in conjunction with reuse of the OWS. Two additional AAP flights were planned for 1969 to revisit the OWS and the ATM using refurbished command modules flown initially on Earth-orbit Apollo flights in 1968. AAP missions planned for low Earth orbit during 1970 would utilize two dual launches (one manned CSM and one unmanned experiment module per dual launch) and two single-launch, long-duration CSM to establish and maintain near- continuous operation of the OWS cluster and a second ATM.

Gagarin and Leonov meet with Kamanin. They discuss the complete inadequacy of Mishin - his excitability, poor knowledge of the Soyuz spacecraft and the details of its operation, his lack of cooperation in working with the cosmonauts in flight and training activities. They urge that these facts be documented in the Komarov crash commission report. Problems are discussed with getting an additional Tu-104 for zero-G/one sixth-G training. Three are needed, and only two have been made available. Even these two can only be used for 23 flights up to 10 August, after which they must be sent away for ejection seat modifications.

The Soviet of Chief Designers met with the Civil Chief Designer UR500K-L1 and recommended that podsadka be dropped and direct flight become the baseline. This was evidently to make possible the objective of a Soviet man around the moon before 4 October 1967. The reasons given were:
a) The successful flights of the UR-500K and Block D on the L1 2P and 3P and the further 4 separate UR-500 launches provided confidence in the launch vehicle's reliability.
b) The main delays with L1 development will be in relation to development by BTsVM of the Argon-11 digital computer for its control system.
c) The failure of 7K-OK number 4 (Soyuz 1) indicated a delay in development of docking in earth orbit.
It was recommended that the 7K-L1 launch sequence be revised to two missions per month as follows:
- 4L - "Zond" unmanned 17 - 29 June 1966
- 5L - unmanned, circumlunar, 27 June - 5 July
- 6L - "Zond", unmanned, 12 - 17 July
- 7L - unmanned, circumlunar, 25 July - 3 August
Followed by manned launches according to astronomical constraints (which would mean 23 August, 21 September, 19 October). (Mishin Diaries 2-22)

Tyulin calls Kamanin. He reports that all of the Chief Designers are in favour of direct L1 flight to the moon instead of the earth orbit rendezvous method. However the Central Committee wants to see four consecutive successful unmanned flights, rather than two, before a manned L1 flight can be made.

Aboard Mishin's aircraft, he discusses his plans with Kamanin. He plans to launch two unmanned Soyuz spacecraft in the second half of July. An automated docking will be attempted, but the mission will be considered successful if the spacecraft rendezvous in space and approach to within 50 to 70 m of each other. He expects to follow this in August with a manned rendezvous, docking, and crew transfer mission. Two further pairs of spacecraft will be available by November 1967. This means a total of eight crews, including back-up crews, will have to be trained. He wants Feoktistov to fly on one of these missions. Kamanin tells Mishin that it will take two to three months to prepare Feoktistov for flight and will be too disruptive to flight training. After arriving at Fedosiya they attend a Soyuz 1 State Commission meeting from 10:00 to 13:00. Tests of the Soyuz parachute system are to be conducted beginning 14 May, on two mass models and one Soyuz mock-up.

The ninth, and last, Force Modernization Minuteman II (LGM-30F) research and development flight test missile^ FTM 2095, was launched from Vandenberg AFB. This missile also carried the fourth Mark 12 reentry vehicle to be test flown on a Minuteman missile launched from Vandenberg AFB.

In the first drop, the reserve parachute didn't open. In the second test, it did inflate, but only after a delay of twenty seconds. TsAGI studies show the drogue chute is creating an area of turbulence in the wake of the capsule, and the reserve chute is deploying right into that zone of chaotic air, preventing it from inflating. Tests on the parachute show that while it was designed to deploy with 1.8 tonnes of drag force from the drogue chute, it actually requires 3-4 tonnes of force to pull the packed parachute out of the container and allow parachute deployment. The parachute fails at 8 tonne load. The Soyuz parachute system is supposed to have a reliability of 95% ... and this essential problem was unknown...

MSC notified NASA Hq. that - with the changes defined for the Block II spacecraft following the January 27 Apollo 204 fire and with CSM delivery schedules now reestablished - it was necessary to complete a contract for three additional CSMs requested in 1966. North American Aviation had responded September 15, 1966, to MSC's February 28 request for a proposal, but action on a contract had been suspended because of the AS-204 accident. NASA Hq. on June 27, 1967, authorized MSC to proceed.

The drop of the Soyuz 1 mock-up at Fedosiya was cancelled due to the great likelihood of loss of the spacecraft and the low likelihood of obtaining any new data as a result. The LII assessment of the parachute system has been completed:

• The likely cause of non-deployment of the primary parachute on Soyuz 1 was insufficient drag force created by the drogue chute to pull it out of the container (the drogue needs to produce 3 tonnes of force, but tests show only 1.1 to 1.8 tonnes of force are being produced at an ambient pressure of 0.67 atmospheres)
• The reliable operation of the reserve parachute and the drogue parachute at the same time was never demonstrated in trials. The chance of them getting tangled was actually very likely.

• Remove the reserve parachute and have a system of two main parachutes, with landing possible even if one of the main chutes does not deploy
• Develop through extensive actual testing reliable inflation of the drogue chute
• Add controls to allow manual parachute deployment by the crew, with appropriate cockpit instruments
• Increase the jettison time of the heat shield from 60.7 seconds to 100 seconds after parachute deployment to allow the full interval for operation of the automatic landing system.

The conclusions of the LII study are found to be sound, but it would take months or even years to implement such an extensive spacecraft redesign. Mishin is still under orders to fly a manned mission around the moon by the 50th Anniversary of the Russian Revolution in October.

Because of the Apollo 204 accident in January and the resulting program delays, NASA realigned its Apollo and AAP launch schedules. The new AAP schedule called for 25 Saturn IB and 14 Saturn V launches. Major hardware for these launches would be two Workshops flown on Saturn IB vehicles, two Saturn V Workshops, and three ATMs. Under this new schedule, the first Workshop launch would come in January 1969.
