Secretary of the Interior Fred A. Seaton and Secretary of the Army Wilber M. Brucker announced that the U.S. Geological Survey had completed the first known photogeological survey of the surface of the moon. The study, part of a program to select lunar landing sites for manned and unmanned spacecraft, consisted of three diagrams, all showing the visible face of the moon at 36 inches diameter. These diagrams depicted, respectively, the physiographic lunar regions, naming features on the moon's surface ; a generalized photogeologic map giving the age of craters and structural features; and the prominent lunar rays.

August 19

The Soviet Union launched its second spaceship satellite, the Korabl Sputnik II, or Sputnik V. The spacecraft was similar to the one launched on May 15 and carried two dogs, Strelka and Belka, in addition to a gray rabbit, rats, mice, flies, plants, fungi, microscopic water plants, and seeds. Electrodes attached to the dogs and linked with the spacecraft communications system, which included a television camera, enabled Soviet scientists to check the animals' hearts, blood pressure, breathing, and actions during the trip. After the spacecraft reentered and landed safely the next day, the animals and biological specimens were reported to be in good condition.

September 30

The fourth meeting of the Space Exploration Program Council was held at NASA Headquarters. The results of a study on Saturn development and utilization was presented by the Ad Hoc Saturn Study Committee. Objectives of the study were to determine (1) if and when the Saturn C-2 launch vehicle should be developed and (2) if mission and spacecraft planning was consistent with the Saturn vehicle development schedule. No change in the NASA Fiscal Year 1962 budget was contemplated. The Committee recommended that the Saturn C-2 development should proceed on schedule (S-II stage contract in Fiscal Year 1962, first flight in 1965). The C-2 would be essential, the study reported, for Apollo manned circumlunar missions, lunar unmanned exploration, Mars and Venus orbiters and capsule landers, probes to other planets and out-of- ecliptic, and for orbital starting of nuclear upper stages.

During a discussion on the Saturn program, several major problems were brought up:

In a memorandum to Abe Silverstein, Director of NASA's Office of Space Flight Programs, George M. Low, Chief of Manned Space Flight, described the formation of a working group on the manned lunar landing program: "It has become increasingly apparent that a preliminary program for manned lunar landings should be formulated. This is necessary in order to provide a proper justification for Apollo, and to place Apollo schedules and technical plans on a firmer foundation.

"In order to prepare such a program, I have formed a small working group, consisting of Eldon Hall, Oran Nicks, John Disher, and myself. This group will endeavor to establish ground rules for manned lunar landing missions; to determine reasonable spacecraft weights; to specify launch vehicle requirements; and to prepare an integrated development plan, including the spacecraft, lunar landing and takeoff system, and launch vehicles. This plan should include a time-phasing and funding picture, and should identify areas requiring early studies by field organizations."

STG formulated a plan for the proposed Apollo Technical Liaison Groups. These Groups were to effect systematic liaison in technical areas related to the Apollo project. The objectives and scope of the plan were as follows:

To carry out these objectives, Technical Liaison Groups would be formed:

Trajectory Analysis;
Studies related to the manned circumlunar mission including atmospheric and non-atmospheric phases of normal and emergency maneuvers.
Configurations and Aerodynamics.
Theoretical and experimental studies of the aerodynamic characteristics and performance of vehicles proposed for the manned circumlunar mission.
Guidance and Control:
Studies and developments in the guidance, navigation, and control areas related to all phases of the manned circumlunar mission.
Convective, conductive, and radiative heat-transfer studies during launch, abort, and reentry for various configurations; investigations of heat transfer through turbulent boundary layers; ablation rates for materials at different heating conditions; and pressure distribution for various configurations.
Structures and Materials:
Studies of design concepts for proposed circumlunar vehicle structures including the optimum payload distribution, protection against radiation and meteoroids, and possible shapes and types of structures suitable for circumlunar missions.
Instrumentation and Communications:
Studies and developments of instruments required for the mission; studies on voice, telemetry, and tracking communications.
Human Factors:
Studies on human tolerance levels, life-support requirements, and the assessment of the biological effects of radiation.
Mechanical Systems:
Studies and developments of systems required for the manned circumlunar mission.
Onboard Propulsion;
Studies and developments in propulsion systems and components required to meet the abort and midcourse performance requirements.
Representatives in a given Group would be limited to a single member from each Center. STG would be responsible for meeting arrangements.

November 22

STG held a meeting at Goddard Space Flight Center to discuss a proposed contract with MIT Instrumentation Laboratory for navigation and guidance support for Project Apollo. The proposed six-month contract for $100,000 might fund studies through the preliminary design stage but not actual hardware. Milton B. Trageser of the Instrumentation Laboratory presented a draft work statement which divided the effort into three parts: midcourse guidance, reentry guidance, and a satellite experiment feasibility study using the Orbiting Geophysical Observatory. STG decided that the Instrumentation Laboratory should submit a more detailed draft of a work statement to form the basis of a contract. In a discussion the next day, Robert G. Chilton of STG and Trageser clarified three points:

  1. The current philosophy was that an onboard computer program for a normal mission sequence would be provided and would be periodically updated by the crew. If the crew were disabled, the spacecraft would continue on the programmed flight for a normal return. No capability would exist for emergency procedures.
  2. Chilton emphasized that consideration of the reentry systems design should include all the guideline requirements for insertion monitoring by the crew, navigation for aborted missions, and, in brief, the whole design philosophy for manned flight.
  3. The long-term objective of a lunar landing mission should be kept in mind although design simplicity was of great importance.
Chilton and Trageser agreed that the purpose of the Apollo program was the development of manned space flight system capability, not simply circumnavigation of the moon with an encapsulated man.
