Chief problems were safe re-entry and recovery of a manned space capsule. Deceleration through re-entry might well exceed the. limits of human tolerance. Experimental evidence, however, suggested that forces high as 18 g's might be tolerated for short periods and that an actual series of tests conducted in Berlin had human subjects enduring 15 g's as long as two minutes without harmful effects., The effect of weightlessness was far more difficult to assess and nearly impossible to simulate for any appreciable length of time other than through actual orbital experimentation. The weight of evidence suggested that manned entry into space and return to earth would be a difficult, but far from impossible, task and the scientific and engineering arts could control the space environment within limits of human tolerance.

Recommendations made by Kamanin's space unit included:

• A KLA aerospace vehicle should be developed. This could be flown in a sub-orbital version at altitudes of 60 to 150 km and as an orbital aero-spaceplane at altitudes of 1000 to 3000 km.
• An aircraft-launcher should be developed to allow air-launch of the KLA as well as air-to-space and space-to-earth missiles
• Navigation, reconnaissance, guidance, and environmental control systems should be developed for the KLA suitable for flights of up to 30 days duration

All systems development is complete, and the two boosters for Vykhod are ready. The launch of the pathfinder spacecraft with mannequins aboard will take place at the end of January, with the manned mission scheduled for March. Leonov's spacesuit is complete, but Zaikin's will not be finished until 5 February, and there will exist only the metal detail parts for Gorbatko's suit.

The Defense Department announced that by the end of FY1965 (June 1965), 150 more ICBM sites would be inactivated and the Atlas E, F, and Titan I missiles removed and placed in storage. The missiles werer stored at San Bernardino Air Materiel Area (SBAMA) facilities at Norton AFB, California. The retired missiles would be replaced by more advanced Minuteman missiles whose annual combat-ready costs were $100,000 per missile compared to nearly $1.0 million for each of the older, more complicated liquid-fueled ICBMs.. In addition, manpower savings would be substantial since only 12 men were required for support of each Minuteman versus approximately 80 for each Atlas or Titan.

A decision made at a Program Management Review eliminated the requirement for a land impact program for the CM to support Block I flights. Post-abort CM land impact for Saturn IB launches had been eliminated from Complex 37 by changes to the sequence timers in the launch escape system abort mode. The Certification Test Specification and related Certification Test Requirements would reflect the new Block II land impact requirements.

Four N1 launches are planned in 1969: The launch of 3L will be followed by 5L, 6L, and 7L in April, June, and November. But this is probably much too optimistic due to delays in delivery of critical systems needed to complete the boosters. But at least 4L, 5L, and 6L should be launched this year.

The launch of the 13th Soviet cosmonaut into space aboard Soyuz 4 is scrubbed - the first launch scrub in the history of Soviet manned launch attempts. Despite -24 deg C temperatures and 8 to 10 m/s winds, the fuelling of the rocket proceeds successfully. Voice communications are lost with Shatalov whenever the television camera is turned on, but it is decided just to leave the camera off and proceed with the launch. Then at T - 9 minutes a problem is detected with the gyro platform of the rocket. It takes three hours to fix, pushing the launch back to 15:00, meaning the landing will have to be in darkness at the end of the mission. It is decided this is too risky, and the launch is cancelled. As Shatalov exits from the spacecraft, he jokes that he has set a new record: shortest space flight, and first to return to its exact point of lift-off. The engineers are concerned with the internal temperature of the SAS abort system solid rockets if left on the pad for 24 hours in these temperatures. The internal temperature of the fuel cannot go below -2 deg C at night. Any lower, the loss of specific impulse of the fuel would reduce the thrust by more than 5%, the limit established for safe operation.

In the evening Afanasyev hosts 100 guests - the leadership of the space program - to watch the big Army-Dinamo football game. Space plans are discussed. The State Commission still needs to confirm the crews for Soyuz 4/5. The issue of automatic versus manual rendezvous is again argued. Kamanin believes this reliance on automated systems has cost the Soviet Union the moon race.

The 'unlucky' Shatalov entered the spacecraft at 10:30. But the -24 deg C weather was below the limits of the booster's gyroscopes. The launch was scrubbed. The launch was made successfully the next day. Later in the day Mishin discussed the N1/L3 project with Afanasyev.

Managers continue to manage electrical power through four of six batteries inside the Zarya module, with battery number one currently in full restoration mode through Monday. Following its restoration, which is conducted on all batteries every six months to maximize charging capacity, battery one will be available for use periodically, if necessary.

Astronauts Kimbrough and Pesquet, in suits 3008 and 3006, performed spacewalk US EVA-39 with depressurization about 1120 UTC and repressurization at 1720 UTC. They moved various adapter plates and batteries of the ISS power system as part of a refurbishment of the entire system. They also moved bundle 2 of the Node 3 Axial shields (covers for a soon-to-be-empty docking port) from the airlock area to Node 3, replaced a camera light tilt assembly and adjusted a worksite interface. At the end of this spacewalk, the SPDM was holding three old NiH3 batteries: 0078 and 0079 on arms 1 and 2, and 0038 on the EOTP (ORU temporary platform). These were to be placed robotically in slots D, E and F on the EP. The EP was to be returned to Kounoutori-6, and destroyed on reentry over the South Pacific.
