MSC called to the attention of North American Rockwell the number of discrepancies found at KSC that could have been found at Downey before hardware shipment. In an effort to reduce the discrepancies North American was requested to obtain and use the KSC receiving inspection criteria as a guide for shipping inspections. It was also suggested that the possibility of sending a few key inspectors to KSC for periods of three to six months to gain additional experience might be investigated.

Bellcomm engineers presented to NASA a proposed plan for lunar exploration during the period from the first lunar landing through the mid-1970s. The proposed program - based upon what the company termed "reasonable" assumptions concerning hardware capabilities, scientific objectives, launch rates, and relationships to other programs - was divided into four distinct phases:

1. an Apollo phase using existing vehicles,
2. a lunar exploration phase employing an extended LM with increased payload and longer staytime,
3. a lunar orbital survey and exploration phase using remote sensors and photographic equipment on a polar orbit flight, and
4. a lunar surface rendezvous and exploration phase using an unmanned LM to deposit the increased scientific equipment and expendables necessary to extend Apollo's manned lunar capability to two-week duration.

NASA lunar exploration program developed for the period from the first lunar landing to the mid-1970s. A lunar exploration program had been developed which would cover the period from the first lunar landing to the mid-1970s. The program would be divided into four phases: (1) An Apollo phase employing Apollo hardware. (2) A lunar exploration phase untilizing an extended LM with increased landed payload weight and staytime capability. (3) A lunar orbital survey and exploration phase using the AAP-1A carrier or the LM/ATM to mount remote sensors and photographic equipment on a manned polar orbit mission. (4) A lunar surface rendezvous and exploration phase which would use a modified LM in an unmanned landing to provide increased scientific payload and expendables necessary to extend an accompanying manned LM mission to two weeks duration.

NASA budgetary restraints required an additional cut in AAP launches. The reduced program called for three Saturn IB and three Saturn V launches, including one Workshop launched on a Saturn IB, one Saturn V Workshop, and one ATM. Two lunar missions were planned. Launch of the first Workshop would be in April 1970.

A Parachute Test Vehicle (PTV) test failed at El Centro, Calif. The PTV was released from a B-52 aircraft at 15,240 meters and the drogue chute programmer was actuated by a static line connected to the aircraft. One drogue chute appeared to fail upon deployment, followed by failure of the second drogue seven seconds later. Additional Details: here....

The geodetic instrumentation systems included (1) four optical beacons, (2) two C-band radar transponders, (3) a passive radar reflector, (4) a sequential collation of range radio range transponder, (5) a Goddard range and range rate transponder, (6) laser reflectors, and (7) Doppler beacons. Non-geodetic systems included a laser detector and a Minitrack interferometer beacon. The objectives of the spacecraft were to optimise optical station visibility periods and to provide complementary data for inclination-dependent terms established by the Explorer 29 (GEOS 1) gravimetric studies. The spacecraft was placed into a retrograde orbit to accomplish these objectives. Operational problems occurred in the main power system, optical beacon flash system, and the spacecraft clock, and adjustments in scheduling resulted in nominal operations.

Area survey photo reconnaissance satellite. Unsuccessful mission. Spacecraft failed to separate from Block I stage. Attempt was made to conduct mission without orientation system. APO self destruct system destroyed spacecraft on 126th revolution over Sea of Okhotsk. First generation, low resolution photo surveillance; recovery probably failed.

He is shown the Volga and L1 trainers, takes a seat in the trainer, and is given a simulated space flight. At the air base he reviews the aircraft and the TBK-60 altitude chamber. Throughout the tour, Mishin constantly wore a soft expression and used coarse language. Afanasyev was briefed on and recognised problems with development and delivery of the Salyut digital computer needed for the L1 guidance system. But he was not told that cooperation had broken down totally on the L3 simulator development and crew selection.

The last scheduled Air Force Thrust Augmented Thor/Agena (SLV-2A //498/SS-01B #2733) to be launched from Vandenberg AFB was the 150th Thor/ Agena vehicle fired from there since Discoverer I was launched on 28 February 1959. From now on, the Air Force would use the more advanced Long Tank Thrust Augmented Thor (SLV-2G) - Thorad - and the newer SLV-2H.

NASA launched Apollo 5 - the first, unmanned LM flight - on a Saturn IB from KSC Launch Complex 37B at 5:48:08 p.m. EST. Mission objectives included verifying operation of the LM structure itself and its two primary propulsion systems, to evaluate LM staging, and to evaluate orbital performances of the S-IVB stage and instrument unit. Flight of the AS-204 launch vehicle went as planned, with nosecone (replacing the CSM) jettisoned and LM separating. Flight of LM-1 also went as planned up to the first descent propulsion engine firing. Because velocity increase did not build up as quickly as predicted, the LM guidance system shut the engine down after only four seconds of operation, boosting the LM only to a 171 x 222 km orbit. Mission control personnel in Houston and supporting groups quickly analyzed the problem. They determined that the difficulty was one of guidance software only (and not a fault in hardware design) and pursued an alternate mission plan that ensured meeting the minimum requirements necessary to achieve the primary objectives of the mission. The ascent stage separated and boosted itself into a 172 x 961 km orbit. After mission completion at 2:45 a.m. EST January 23, LM stages were left in orbit to reenter the atmosphere later and disintegrate. Apollo program directors attributed success of the mission to careful preplanning of alternate ways to accomplish flight objectives in the face of unforeseen events.

The 'big' Soviet of Chief Designers meets and the three-launch landing concept developed a month earlier is presented in detail. Pilyugin pointed out that this was a typical contradiction. Mishin had just made a presentation to the expert commission justifying that the one-launch scheme was safe and reliable. Now they wanted to put forward a new scheme because the one-launch scheme was unsafe and unfeasible. Additional Details: here....

The parachute failed to inflate after the capsule separated from the escape tower. The recovery apparatus on both the Soyuz and L1 versions of the capsule continue to perform badly. The soft landing engines have ignited at altitudes of 2000 to 4000 m instead of the 1.2 m required for a soft landing. On the first UR-500K abort the SAS functioned, but the parachute failed to separate after landing, dragging the capsule for 600 m across the steppes. On the second UR-500K abort, there was a premature opening of the parachute, and reaction control system venting led to burn-through of some of the parachute lines.

Kamanin, Gagarin, Titov, Popovich, Belyayev, and Leonov meet with Marshal Yakabovskiy. They inform him that Mishin is blocking further development of the 7K-VI military manned spacecraft and also trying to kill Chelomei's Almaz military space station. They get nowhere. The Marshal says that while he doesn't understand much about space himself, Ustinov had assured him that Mishin and Afanasyev were taking all measures necessary to correct the necessary material...

Nomenclature for the OWS included in the AAP presented in the FY 1969 budget was confirmed by NASA. The ground-outfitted OWS to be launched with Saturn V would be designated the 'Saturn V Workshop.' (This had sometimes been called the 'dry Workshop.') The OWS that would be launched by a Saturn IB would be referred to as the 'Saturn I Workshop.' (Colloquially it had been referred to as the 'wet workshop.') Terminology 'Uprated Saturn I' would not be used officially. This launch vehicle would be referred to as the 'Saturn IB.'

Chertok compared the "Kontakt" and "Liga" systems, and noted that the "Liga" elements in the control loop control system simplified LK landing. MS Ryazanskiy noted that this contradicted a decision two years ago to have the LK make an autonomous landing on the moon (LK homing on and landing near a beacon was postponed at that time). But AS Mnatsanakyan supported the approach, saying it was necessary to speed up the development of the "Liga"; it provided a precision landing on the moon within 50 to 100 m of the target. (Mishin Diaries 2-120).

In preparation for a Soviet of Chief Designers four days later, detailed consideration of many issues was underway. Among them, changes to the baseline LK orbit and ascent trajectories to allow rendezvous with the waiting LOK even after a delay of more than six orbits in departure; and changes to the landing profile to prevent shrapnel from jettison of the LKR's Block D lunar crasher stage impacting the waiting cosmonaut's LK. 250 liters of increased propellant would be required in the LKR for a higher Block D jettison; or the Block D could make a maneuver after separation to assure it would impact well away from the active landing site. (Mishin Diaries 2-119)

VVS Party Conference. It is clear to Kamanin that there is no support from the Air Force for manned spaceflight. Kamanin only heard yesterday that Babakin is working on an automatic soil sample return spacecraft. He will need a minimum of two to three years to complete it. Kamanin complained that it would interfere with plans for the L1 program. An uninterrupted series of flights will be needed to complete the L1 spacecraft qualification, and the Ye-8, using the same booster, could be an interference in achieving that goal.

A Senior Flammability Review Board meeting at MSC reached a number of decisions on the CSM. Attending were Robert R. Gilruth, chairman; George M. Low, Kenneth S. Kleinknecht, Aleck C. Bond, Maxime A. Faget, Donald K. Slayton, Charles A. Berry, and Rodney G. Rose, all of MSC; Samuel C. Phillips, NASA Hq.; William B. Bergen and Dale D. Myers, North American Rockwell; and George Stoner, Boeing (nonvoting observer).

Several previous action assignments were reviewed:

1. Component level Flammability Test Program - North American reviewed the results of its material identification and test program, the component test program, and the boilerplate 1,250 tests. These tests had provided the basis for design decisions on selection and application of CM nonmetallic materials.
2. Boilerplate 1224 configuration comparison to CSMs 2TV-1 and 101 - North American presented the comparison and the Board decided that the boilerplate configuration was representative of the "worst case" configuration, considering both 2TV-l and 101.
3. Internal ignition rationale - ignition rationale for the boilerplate 1224 tests was presented to the Board. Nichrome wire ignitors were used with the ignitor wire embedded in potting. In some locations a Ladicote cover was applied over the potting and ignitor. The Board pointed out that the ignition techniques were not really representative of actual operating conditions and were indeed overly severe.
4. Crew communications umbilical - North American was evaluating a fluorel crew communications umbilical as well as fluorel oxygen umbilicals. A Beta sleeve over the oxygen and crew communications umbilicals would also be evaluated for its operational acceptability by the Crew.

The Board concluded that the material changes made in the CM had resulted in a safe configuration in both the tested atmospheres. The Board agreed "that there will always be a degree of risk associated with manned space flight," but the risk of fire "was now substantially less than the basic risks inherent in manned space flight."

Among decisions reached were:

1. the CSM 2TV-1 and 101 coaxial cable configuration would be tested in the 60-percent-oxygen and 40-percent nitrogen atmosphere;
2. material improvements and testing would be continued and changes would be phased in, pending the availability of proved materials; and
3. action would be taken to be prepared to use a 60-percent-oxygen and 40-percent-nitrogen prelaunch atmosphere in CSM 101.

The final medical report rejects Feoktistov's fitness to be a cosmonaut. Mishin accepts the findings of the report, but in classic manner ignores it and advocates Feoktistov be appointed as commander of the active spacecraft in the first Soyuz docking mission after return to flight. Kamanin is livid. Feoktistov has had years of training for EVA, but he has not had one day of training as a spacecraft commander, and now he wants him to command a mission due to launch in only two to three months! However agreement is finally reached on L1 commander assignments: Leonov, Bykovskiy, Popovich, Voloshin. Agreement is not reached on the second (civilian) crew member position for the flights. According to Mishin, the Soyuz and L1 flights planned from March 1 to the end of 1968 will require 16 to 18 crew members total.

Failed launch of an E-6LS radio-equipped version of the E-6 used to test tracking and communications networks for the Soviet manned lunar program. Suggestions for the abnormal consumption included the seizing up of a pintle valve for controlling fuel supply into the regulator or the seizing up of the fuel inlet control. The upper stages broke up in the atmosphere.

Grumman President L. J. Evans wrote ASPO Manager George M. Low stating his agreement with NASA's decision to forego a second unmanned LM flight using LM-2. (Grumman's new position - the company had earlier strongly urged such a second flight - was reached after discussions with Low and LM Manager G. H. Bolender at the end of January and after flight data was presented at the February 6 meeting of the OMSF Management Council.) Although the decision was not irreversible, being subject to further investigations by both contractor and customer, both sides now were geared for a manned flight on the next LM mission. Additional Details: here....

It is currently organised in three cosmonaut detachments: Nikolayev commands the first detachment, which is training for L3, L1, and Soyuz fiights. Popovich commands the second, training for Almaz and 7K-VI military space missions. Nikeryasov commands the third, which is the 'observer' detachment.

Kamanin states his belief that the L1 will not be ready for manned flight for 2 to 3 years, and will need 8 unmanned flight tests before it can be man-rated. Others disagree, and the final decision is that four unmanned flights without significant failure will be required before the spacecraft is man-rated.

In discussing the results of a manned test with MSC Director Robert R. Gilruth, George M. Low mentioned that a single 45-degree motion of the abort handle was required to initiate a launch abort in Apollo. Gilruth voiced concern that an abort could be caused by a single motion. Additional Details: here....

The booster failure on the previous launch was found to be due to premature fuel injection during engine start, causing initial chamber temperatures to rise 200 degrees above normal. Glushko and Konopatov both guarantee their engines for the next launch. The next L1 flight will use the 'Kruga' landing predictor. This will predict the landing point to within a 150 x 150 km area two to three hours before re-entry. Landing points on the three previous flights would have been 2000 km from Madagascar and India, Novosibirsk, and the North Pole... Mishin plans the next dual Soyuz flight for 5-10 April. Kamanin protests that the parachute and sea trials of the redesigned capsule are not yet complete. Mishin, as usual, dismisses his concerns.

Keldysh heads a Soviet on plans through 1975 for automated probes and space research of the moon and planets. Barmin attends, his interest being the relation of this work to his lunar base. Kamanin finds the plan not well thought out... Tereshkova sees Kamanin and tells him she cannot handle the stress of both political demands on her time and cosmonaut training. She wants Kamanin's assistance to get her out of political tasks.

For this L1 launch Chelomei wants to film separation of the first and second stages of the Proton rocket at 126 seconds into the flight - altitude 41 km, distance downrange 47 km. To do this two An-12 and one Tu-124 with long focal-length cameras will orbit 35 to 40 km from base. The discussion turns to how to recover the L1 if it lands in the ice-bound Aral Sea. The circle of possible landing points has a radius of 500 km from a point west of Karaganda. For political reasons it is not possible to deploy recovery forces to areas of Iran and India that are within this circle.

What at first seemed to be a success, very much needed by the L1 program, ended in failure. The Proton booster lifted off in 18 m/s winds, -3 deg C temperatures, and into very low clouds - it disappeared from view at only 150 m altitude. Aircraft at 9, 10, and 11 km altitude reported the cloud deck topped 8300 m, with 1.5 to 2.0 km visibility. The spacecraft was successfully launched into a 330,000 km apogee orbit 180 degrees away from the moon. On reentry, the guidance system failed, and the planned double skip maneuver to bring the descent module to a landing in the Soviet Union was not possible. Ustinov had ordered the self-destruct package to be armed and the capsule blew up 12 km above the Gulf of Guinea. Kamanin disagreed strongly with this decision; the spacecraft could have still been recovered in the secondary area by Soviet naval vessels after a 20 G reentry. The decsion was made to recover the spacecraft in the future whenever possible.
Officially: Solar Orbit (Heliocentric). Study of remote regions of circumterrestrial space, development of new on-board systems and units of space stations.

At 07:35 the first midcourse manoeuvre for Zond 4, then 225,000 km from earth, was cancelled due to an orientation system problem. The sun tracker worked, but the star tracker could not acquire Sirius. The first and second midcourse manoeuvres are not strictly necessary. However if the third midcourse fails, when the spacecraft is 167,000 km from earth on the return leg, the spacecraft will miss the atmosphere and head back out into space. A meeting is held on cosmonaut training. The simulators are still not adequate. Feoktistov is still demanding that he be trained for the first Soyuz docking mission.

OGO 5 carried 25 experiments, 17 of which were particle studies, and two were magnetic field studies. In addition, there was one each of the following types of experiments: radio astronomy, UV spectrum, Lyman-alpha, solar X ray, plasma waves, and electric field. By April 1971, spacecraft perigee had increased to 26,400 km and inclination had increased to 54 deg. The spacecraft attitude control failed on August 6, 1971, after 41 months of normal operation. The spacecraft was placed in a standby status on October 8, 1971. Four experiments (Meyer, Blamont, Thomas, and Simpson) were reactivated for the period from June 1 to July 13, 1972, after which all operational support terminated. Spacecraft orbit parameters changed significantly over the spacecraft life.

The L1 reaches its apogee. The time comes to attempt the third midcourse manoeuvre. There are three attempts to orient the spacecraft. The first was at the minimum sensitivity setting for the star tracker, the second at the maximum setting, and the third using a high-density filter. Sirius is finally acquired the third time. The spacecraft is oriented and makes a 15 second burn with a 9.129 m/s delta-V (versus 9.202 m/s planned). This is good enough to assure the spacecraft will hit the re-entry corridor without a further correction.

Design Certification Reviews of CSM 101 and LM-3 were held at MSC. Significant program-level agreements reached included validation of a 60-percent-oxygen and 40-percent-nitrogen cabin atmosphere during launch; reaffirmation of the February 6 Management Council decision that a second unmanned LM flight was not required; and the conclusion that, in light of successful static firing of the 102 service propulsion system and subsequent analysis, a static-firing of the 101 system was not required.

It is estimated that Zond 4 will fly 45.8 km below the initial re-entry corridor at an altitude of 145 km, after which it will ricochet back out into space and proceed to a final re-entry and landing on Soviet territory. It is calculated it will land on 7 March at 21:56, 13 minutes later than the originally estimated time.

Mishin certified to MAP on 5 March that the Soyuz parachute system development is complete, but Tkachayev has dissented, saying that the system was unreliable and overweight (this from the same chief designer that certified the previous design as having an 0.999 reliability!). The parachute trials will not be finished until May - meaning there will be no manned Soyuz launch in April. This problem is holding up the L1, L3, and Almaz projects as well.

The L1's SUS guidance system failed on re-entry. It hit the atmosphere precisely at the calculated time, but wasn't guided to generate lift and fly out of the atmosphere again. A ballistic re-entry would mean no recovery on Soviet soil, so the APO destruct system automatically blew up the capsule at 10 to 15 km altitude, 180-200 km off the African coast at Guinea.

NASA technicians at KSC completed the flight readiness test for Apollo 6. The two-day event was delayed several days because of difficulties in modifying the service propulsion system tank skirt. With that significant launch-preparation event completed, program officials were reassessing the launch date in light of work remaining on the vehicle.

The ATM Principal Investigators presented the status of their experiments at Ball Brothers Research Corporation in Boulder, Colorado. They reported good progress in the development of their instruments and presented material to support their assessment that delivery would be on schedule. They also stressed the importance of flying a mission as early as possible during a period of high solar activity.

Gagarin wants better organisation of the TsPK for the L1 circumlunar manned flights, including: better training in manual navigation in case of failure of automated systems; improved training in survival of 20 G re-entries if the automated SUS capsule guidance system fails. The cosmonauts review material for the Seventh International UFO Conference in Mainz (!).

Titov is going to Italy, Feoktistov to Hungary. The 30 month program for the L3 lunar landing is settled. The cosmonauts already began training in January. The first LK lunar lander will be tested in low earth orbit in the second half of 1969. The first Soviet manned lunar landing cannot take place any earlier than 1970-1971. The resolution had set the date as 1967-1968, but the N1 and L3 will not be ready in time. The L3 is still conceptual, a purely paper spacecraft. The first N1 was to have been moved to the pad by March of this year, but it won't even make that milestone by May.

Six Apollo spacecraft are to be flown into earth orbit in 1968, four unmanned and two manned. Five flights are planned for 1969, including the first landing on the moon. Beyond this is the Apollo Applications Program. Expenditures for this are planned as $179 million in 1968 and $435 million in 1969, leading to the first orbital laboratory in 1970.

Meeting with Gay Ilyich Severin. Two spacesuits are being developed for the L3 program: the Krechet-94 and Orlan. Both have been in development for two years. The Krechet-94 will allow six hours of lunar surface activity, the Orlan, 2.5 hours. Both weigh about 90 kg. There are consumables for a total of 52 hours of life support in the LK and the LT Lunar Cart. Kamanin feels the suits are too heavy, due to Mishin's demand for a 5 km range from the LK over a three day traverse with the LT. Severin could have instead developed the spacesuit used by Leonov to have a four hour autonomous operation, but Mishin insisted on doubling of the capacity.

The lunar landing research vehicle was operating and training was being conducted, MSC Director Robert R. Gilruth wrote Langley Research Center's Acting Director Charles J. Donlan. MSC intended to conduct a second class for LLRV pilots and one of the first requirements for checkout was a familiarization program on Langley's Lunar Landing Research Facility. He requested that a program be conducted for not less than four nor more than six MSC pilots between April 15 and May 15.

Apollo drogue chute test 99-5 failed at the El Centro, Calif., parachute facility. The drop was conducted to demonstrate the slight change made in the reefed area and the 10-second reefing cutter at ultimate load conditions. The 5,897-kilogram vehicle was launched from a B-52 aircraft at 10,668 meters and programmer chute operation and timing appeared normal. At drogue deployment following mortar activation, one drogue appeared to separate from the vehicle. Additional Details: here....

Hours are spent arguing over flying Feoktistov as a cosmonaut. Finally the matter is referred to the VPK. Kamanin briefs Ustinov's deputy on his position against Feoktistov. The L1 is reviewed. The star sensor only operated on Zond-4 on the fourth day of flight. However when it worked, it provided a 2 km positional accuracy at re-entry versus the 10 km required. The next L1 is to be launched on 23 April. If that date cannot be met, it will be launched on 25-30 April on a deep-space trajectory (not aimed at the moon).

The Joint Pacific Area Scheduling Office (JPASO) was established at Vandenberg AFB to centralize coordination and scheduling for all Department of Defense offensive/defensive ballistic missile tests.This was without regard to point of origin. Representatives from the Air Force Western Test Range, the Army's Kwajalein Missile Range (KMR), and the Navy's Pacific Missile Range (PMR) were the primary participants in the scheduling meetings.

Russian pilot cosmonaut 1960-1968. First person in space. Due to his fame, the Soviet leadership did not want to risk him on another flight, but later relented. Died in MiG trainer crash while requalifying for flight status. 1 spaceflight, 1.8 hours in space. Flew to orbit on Vostok 1 (1961). Gagarin was flying 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.

After completion of an agreement between the Defense Department and the North Atlantic Treaty Organization (NATO), SAMSO initiated procurement of a two-satellite communications system for NATO. Philco-Ford Corporation was selected to build the two satellites that would be nearly identical to those produced for the United Kingdom's Skynet program.

NASA Hq. confirmed oral instructions to MSC and KSC to use 60 percent oxygen and 40 percent nitrogen to pressurize the Apollo CM cabin in prelaunch checkout operations and during manned chamber testing, as recommended by the Design Certification Review Board on March 7 and confirmed by the NASA Administrator on March 12. This instruction was applicable to flight and test articles at all locations.

The second successful launch of the Saturn V stunned the Soviet engineers. They could not believe the variety and volume of data telemetered back in real-time to the launch centre. They viewed with jealousy the launch room set-up at Cape Canaveral - where each engineering speciality could sit in their own comfortable chair, viewing data as the booster ascended on a computer screen.

He agrees that only pilots should be assigned as crew commanders. However he says that the increase of the training centre to 500 staff will need discussion with the party. Furthermore, Kamanin's wish to move management of manned spacecraft projects from the RSVN to the VVS is a 'difficult subject' that has to be discussed at the highest levels of the Ministry of Defence.

Apollo 6 (AS-502) was launched from Complex 39A at Kennedy Space Center. The space vehicle consisted of a Saturn V launch vehicle with an unmanned, modified Block I command and service module (CSM 020) and a lunar module test article (LTA-2R).

Liftoff at 7:00 a.m. EST was normal but, during the first-stage (S-IC) boost phase, oscillations and abrupt measurement changes were observed. During the second-stage (S-II) boost phase, two of the J-2 engines shut down early and the remaining three were extended approximately one minute to compensate. The third stage (S-IVB) firing was also longer than planned and at termination of thrust the orbit was 177.7 x 362.9 kilometers rather than the 160.9-kilometer near-circular orbit planned. The attempt to reignite the S-IVB engine for the translunar injection was unsuccessful. Reentry speed was 10 kilometers per second rather than the planned 11.1, and the spacecraft landed 90.7 kilometers uprange of the targeted landing point.

The most significant spacecraft anomaly occurred at about 2 minutes 13 seconds after liftoff, when abrupt changes were indicated by strain, vibration, and acceleration measurements in the S-IVB, instrument unit, adapter, lunar module test article, and CSM. Apparently oscillations induced by the launch vehicle exceeded the spacecraft design criteria.

The second-stage (S-II) burn was normal until about 4 minutes 38 seconds after liftoff; then difficulties were recorded. Engine 2 cutoff was recorded about 6 minutes 53 seconds into the flight and engine 3 cutoff less than 3 seconds later. The remaining second-stage engines shut down at 9 minutes 36 seconds - 58 seconds later than planned.

The S-IVB engine during its first burn, which was normal, operated 29 seconds longer than programmed. After two revolutions in a parking orbit, during which the systems were checked, operational tests performed, and several attitude maneuvers made, preparations were completed for the S-IVB engine restart. The firing was scheduled to occur on the Cape Kennedy pass at the end of the second revolution, but could not be accomplished. A ground command was sent to the CSM to carry out a planned alternate mission, and the CSM separated from the S-IVB stage.

A service propulsion system (SPS) engine firing sequence resulted in a 442-second burn and an accompanying free-return orbit of 22,259.1 x 33.3 kilometers. Since the SPS was used to attain the desired high apogee, there was insufficient propellant left to gain the high-velocity increase desired for the entry. For this reason, a complete firing sequence was performed except that the thrust was inhibited.

Parachute deployment was normal and the spacecraft landed about 9 hours 50 minutes after liftoff, in the mid-Pacific, 90.7 kilometers uprange from the predicted landing area (27.40 N 157.59 W). A normal retrieval was made by the U.S.S. Okinawa, with waves of 2.1 to 2.4 meters.

The spacecraft was in good condition, including the unified crew hatch, flown for the first time. Charring of the thermal protection was about the same as that experienced on the Apollo 4 spacecraft (CM 017).

Of the five primary objectives, three - demonstrating separation of launch vehicle stages, performance of the emergency detection system (EDS) in a close-loop mode, and mission support facilities and operations - were achieved. Only partially achieved were the objectives of confirming structure and thermal integrity, compatibility of launch vehicle and spacecraft, and launch loads and dynamic characteristics; and of verifying operation of launch vehicle propulsion, guidance and control, and electrical systems. Apollo 6, therefore, was officially judged in December as "not a success in accordance with . . . NASA mission objectives."

Astronauts James A. Lovell, Jr., Stuart A. Roosa, and Charles M. Duke, Jr., participated in a recovery test of spacecraft 007, conducted by the MSC Landing and Recovery Division in the Gulf of Mexico. The test crew reported that while they did not "recommend the Apollo spacecraft for any extended sea voyages they encountered no serious habitability problems during the 48-hour test.

Lunar Orbiter; studied lunar gravitational field, Earth-Moon gravitational relationship, and conducted further scientific experiments in circumlunar space. Not revealed until years later was that the E-6LS was primarily intended to test tracking and communications networks for the Soviet manned lunar program. The Luna 14 spacecraft entered a 140 x 870 km x 42 degree lunar orbit on April 10, 1966. The spacecraft instrumentation was similar to that of Luna 10 and provided data for studies of the interaction of the earth and lunar masses, the lunar gravitational field, the propagation and stability of radio communications to the spacecraft at different orbital positions, solar charged particles and cosmic rays, and the motion of the Moon. This flight was the final flight of the second generation of the Luna series.

No cosmonauts will be sent to witness the next series of unmanned Soyuz flights beginning on 14 April. All cosmonaut staff efforts are concentrated on the Gagarin crash investigation. Kamanin notes the flight of Apollo 6. According to his information the first manned Apollo flight will take place in May-October 1968, and the first American moon landing by the end of 1969.

Cosmos 213 was the target for Cosmos 212 in a successful test of Soyuz 7K-OK rendezvous and docking systems. The Cosmos 213 launch was the most accurate yet. The spacecraft was placed in orbit only 4 km from Cosmos 212, ready for a first-orbit docking. Both spacecraft were recovered, but Cosmos 213 was dragged by heavy wind across the steppes when the parachute lines didn't jettison at touchdown. This failure caused the upcoming Soyuz 2/3 manned docking mission to be scaled back.
Officially: Investigation of outer space, development of new systems and elements to be used in the construction of space devices. Additional Details: here....

This was a reserve day in the L1 countdown, in case of problems in preparation. However all is on schedule for the launch. The same cannot be said for the N1. There are many delays. Mishin promised the first N1 rollout in the first half of March, but it is still in the assembly building, with no end in sight of preparations. The weather at the cosmodrome is -5 deg at night, clear pleasant days. The Hotel Kosmonavt was finished on 15 April. Although it has all of its furniture, it was not completely painted before the furniture was moved in!

However the Commission did not agree to disarm the APO destruct system aboard the capsule. They don't want any chance of 'Soviet electronic secrets' falling into the hands of the Americans. Kamanin disagrees - he thinks they should conduct one fully ballistic re-entry and landing of an L1 to see if the landing system would function and the crew would survive. What's the point of deploying recovery ships to the Indian Ocean if they are only going to blow up the capsule anyway if the SUS fails and it reverts to ballistic mode? Mishin's answer: 'I was always against having those forces in the Indian Ocean!' Yet he had demanded those 7 to 9 recovery ships in February!

L1 launch attempt, lift-off at 02:00 local time. The spacecraft was to separate at 589 seconds into the flight. Instead at 260 seconds, a short circuit in the malfunction detection system incorrectly indicated a launch vehicle failure. This in turn triggered the SAS abort system. The SAS shut down the good stage and separated the spacecraft from the booster. The capsule landed safely 520 km downrange from the launch site. This was the third such abort, which if nothing else proved the reliability of the SAS - all of the spacecraft landed safely.

The cosmonauts and VVS staff will watch the Proton launch from Area 130. Kamanin observes from Area 81, near the pads. It is a warm, starry night and the booster heads toward space on pillars of fire. Up until T+260 seconds all proceeds normally, then the stage 2 shuts down 79 seconds into its burn. At 02:50 it is reported that the capsule separated successfully from the inert booster and has landed 520 km from the launch pad, 110 km east of Dzhezkazgan. Two Il-14 search aircraft and one Mi-4 helicopter fly over the recovery zone, but no signal is received from the capsule. Mishin immediately blames Chelomei's TsKBEM for the booster failure -- later it is shown that Mishin's L1 spacecraft sent an erroneous abort command to the rocket, which then shut down it engines! The capsule is sighted after dawn and picked up by a Mi-6 helicopter and delivered to Dzhezkazgan airfield at 15:00. It is then taken to Moscow for examination. The SAS abort and capsule landing systems have certainly been proven reliable! They have worked perfectly on the last three launches!

Over 10,000 people come out to the steppe, some driving hundreds of kilometres for the event. Kamanin discharges Matinchenko from the cosmonaut corps. He was in two bad automobile accidents on 19 and 21 April. In one of the accidents a six-year-old child was killed.

ASPO Manager George M. Low explained to the Apollo Program Director the underlying causes of slips in CSM and LM delivery dates since establishment of contract dates during the fall of 1967. The general excuse, Low said, was that slips were the result of NASA-directed hardware changes. "This excuse is not valid." He recounted how NASA-imposed changes had been under strict control and only essential changes had been approved by the MSC Level II Configuration Control Board (CCB). Additional Details: here....

Nikolayev is to be commander of the first group, with Leonov as his deputy. Titov would command the second group, with Popovich as his deputy. But Kamanin doesn't consider any of them to be command officer material yet. The automobile accidents of Popovich, the mess that led to Matinchenko's dismissal, the bad performance of Belyayev in his duties as chief of staff of the VVS group at Baikonur - none of these men have any discipline!

Mishin calls Kamanin and asks what he would think of a revised scenario for the next manned Soyuz flight. Mishin's '2+2' concept would call for four, instead of five cosmonauts, aboard two Soyuz capsules with transfer of only one cosmonaut by EVA. He gives Kamanin until 6 May to give his opinion on the change of plan. Titov is planning on selling his Volga automobile and buying a Moskovich.

Headquarters USAF issued a System Management Directive (SMD) to initiate the Hard Rock Silo (HRS) Development Program for Minuteman III. The aim of the program was to develop and test a new, very hard basing system that would be compatible with an Advanced ICBM but initially used for Minuteman III. This SMD was the culmination of previous studies undertaken by the Defense Department and the Air Force on advanced ICBM systems.

It is decided that the TsPK will be named for Gagarin. Meanwhile 400 soldiers and 50 officers have combed the Gagarin crash site, recovering pieces of the aircraft. Gagarin's widow will receive a one-time payment of 5000 roubles, plus 200 roubles/month pension, plus 100 roubles/month for Gagarin's daughter. This is in addition to base amounts of 150/month for the widow and 75/month for the daughter.

Lunar landing research vehicle (LLRV) No. 1 crashed at Ellington Air Force Base, Tex. The pilot, astronaut Neil A. Armstrong, ejected after losing control of the vehicle, landing by parachute with minor injury. Estimated altitude of the LLRV at the time of ejection was 60 meters. LLRV No. 1, which had been on a standard training mission, was a total loss - estimated at $1.5 million. LLRV No. 2 would not begin flight status until the accident investigation had been completed and the cause determined. Additional Details: here....

Kamanin meets with Yuryshev, Deputy Chief of NTK/General Staff, and Maksimov, Deputy Chief of TsKIK, to review military spacecraft. Such spacecraft can be placed in two general categories: Category 1 would be manoeuvrable spacecraft that use active gliding to be guided to a landing point. This technology was currently being developed in the Soyuz and L1 projects. Category 2 would be an orbital aircraft which would be launched from a winged, recoverable, aircraft first stage booster. Less work has been accomplished on such spacecraft. The Mikoyan and Tupolev bureaux have been authorised to begin design and development, but this was still in its earliest stages. But Kamanin believes the second approach has the greatest future potential, and should be pursued more vigorously.

Kamanin reviews the ongoing controversy with Mishin over assignment of Feoktistov to spaceflights. He then turns to the trials of the revised parachute system for Soyuz. The new design has been proven in three landings of spacecraft and 23 tests of mock-ups from aircraft. The SAS abort system has not been retested -- Korolev took full responsibility for its design, and the VVS accepted that in the old days. In any case the likelihood of having to use the SAS or the reserve parachute was not great. Yet still Mishin refuses to recommend going ahead with manned flights. 'I will only proceed when the Central Committee orders me!' he has said. Nevertheless he does declare that Soyuz is now ready to resume manned flights, except for the reserve parachute system, which needs two to three months more development. Based on successful completion of these tests, a manned flight will be possible in the first half of August.

A September 1968 flight test was planned. However the first stage LOX tank developed hairline cracks during ground tests. 4L was removed from the pad in June 1968. The first stage was cannibalized; the upper stages were incorporated into the 1M1 mockup for further training of the launch crews.

Holidays - in the first ten days of May, the civilians work only two days, while the military must work four. Kamanin assigns cosmonauts to the State Commission that will select the design for the Gagarin memorial obelisk. He then reviews cosmonaut pilot aircraft type qualifications. Titov is current on the Su-7, MiG-21, and several other high-performance aircraft. Nikolayev and Leonov are still certified to fly two or three MiG fighter types. Belyayev, Bykovsky, Popovich, Kutachov, and the others are only current on the L-29 trainer. The L-29 is 20 times more reliable than the MiG-21 or Su-7, and the MiG-15 trainer is 4x to 5x more reliable than the high performance types. In general the cosmonauts are against plans to move the air regiment to TsPK from Chkalovsky air field due to greater air space restrictions over Moscow.

One engineer has resigned in the belief that the Gagarin crash was due to a hydraulic accumulator failure. The reason Mishin has been pushing for a reduced Soyuz crew is revealed when the reserve parachute will burst when subjected to forces greater than 1300 kgf/square metre. This implies that the Soyuz SA has to be reduced by 150 to 200 kg mass to allow safe functoning of the reserve parachute in an emergency. A reserve parachute system redesign is not an alternative due to the schedule requirements. Mishin's solution is to fly only two crew in each Soyuz. So he is proposing that the two-Soyuz manned flight carry only two crew in each capsule. No crew transfer will take place, but the BO living module will be depressurised to check its function as an airlock. Kamanin is furious -- this conclusion is reached now, when two years ago crews were standing by for launch on what is now believed to be an unsafe mission! The cosmonauts are also against Mishin's concept - such a flight proves nothing new.

Christopher C. Kraft, Jr., MSC Director of Flight Operations, expressed concern to ASPO Manager George M. Low over the escalation of E-mission objectives; the flight now loomed as an extremely complex and ambitious mission. The probability of accomplishing all the objectives set forth for the mission, said Kraft, was very low. He did not propose changing the mission plan, however. "If we are fortunate," he said, "then certainly the quickest way to the moon will be achieved." Kraft did suggest caution in setting mission priorities and in "apply(ing) adjectives to the objectives." Additional Details: here....

Volynov conducts tests in a pressurised suit to see if it is possible to go from the SA capsule to the BO living module in a two-man crew transfer scenario. He shows it is not possible - exit from the SA to the BO is very unsafe, there is a good chance of getting stuck in the hatch. This shows it would be difficult or impossible for the spacecraft commander in the SA to go to the assistance of a single cosmonaut attempting to transfer from one Soyuz to another. Feoktistov proposes another alternative - launch of 3 cosmonauts in one Soyuz, one cosmonaut in another. After docking, a single cosmonaut would transfer from one Soyuz to another, but at least a second cosmonaut would be in the BO to assist him in case of difficulties. Two cosmonauts would return in each Soyuz capsule, meeting the reserve parachute mass limitations. This solution also takes care of a problem with the 1+2 scenario, in that it implied a crew consisting of Khrunov and Yeliseyev, but neither has been trained as a spacecraft commander. A crew could consist of Volynov and one of these, but then the problem is that no spacesuit has been fabricated for Volynov, and it requires two months to make one.

Titov is to tour. He will spend the next two days in Semipalatinsk, then go to Italy in the first week of June. He has been offered command of the second unit at TsPK, but says he doesn't want to be an administrator. He would rather pursue a career as a test pilot, at either OKB MiG or GNIKI VVS. Mishin is now pushing for a 1+2 Soyuz mission in August on safety grounds. He is also still pushing Khrunov as a spacecraft commander, even though Khrunov has no training in manual docking and it would take at least two months to train and qualify him.
