1960August 8In a memorandum to Abe Silverstein, Director of NASA's Office of Space Flight Programs, Harry J. Goett, Director of Goddard Space Flight Center, outlined the tentative program of the Goddard industry conference to be held on August 30. At this conference, more details of proposed study contracts for an advanced manned spacecraft would be presented. The requirements would follow the guidelines set down by STG and presented to NASA Headquarters during April and May. Three six-month study contracts at $250,000 each would be awarded.Draft Memorandum, Goett to Director, Office of Space Flight Programs, August 8, 1960.
August 13Secretary 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.Palo Alto Times, August 18, 1960.
August 19The 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.Baltimore Sun, August 20, 1960; New York Herald Tribune, August 22, 1960; Instruments and Spacecraft, pp. 120-121.
August 30The Goddard Space Flight Center GSFC conducted its industry conference in Washington, D.C., presenting details of GSFC projects, current and future. The objectives of the proposed six-month feasibility contracts for an advanced manned spacecraft were announced:
September 1In an organizational change within STG, Maxime A. Faget was appointed Chief of the Flight Systems Division and Robert O. Piland was named Assistant Chief for Advanced Projects. The Apollo Project Office was formed with Piland as Head of the Office; members included John B. Lee, J. Thomas Markley, William W. Petynia,and H. Kurt Strass.Memorandum, Robert R. Gilruth to Staff, STG, "Change in Organization of the Space Task Group," September 1, 1960.
September 2NASA Administrator T. Keith Glennan directed that an accelerated joint planning effort be made by persons at NASA Headquarters who were most familiar with the Saturn, Apollo, manned orbital laboratory, and unmanned lunar and planetary programs. They were to determine whether the Saturn and Saturn-use programs were effectively integrated and whether sufficient design study and program development work had been done to support decisions on projected Saturn configurations. The group responsible for the study consisted of Lloyd Wood, Richard B. Canright, Alfred M. Nelson, John L. Sloop, Oran W. Nicks, Fred D. Kochendorfer, and George M. Low.Memorandum, Donald H. Heaton to Director, Launch Vehicle Programs, and Director, Space Flight Programs, "Integration of the Saturn and Saturn Applications Programs," September 2, 1960.

September 29In a memorandum to NASA Associate Administrator Robert C. Seamans, Jr., Robert L. King, Executive Secretary, described the action taken on certain items discussed at the July 14-15 meeting of the Space Exploration Program Council. Among these actions was the awarding of a contract to The RAND Corporation to evaluate missions for which nuclear propulsion would be desirable. Included in the study would be the determination of availability dates, cost of development, operational costs, the safety aspects of the missions, and an evaluation of research requirements.Memorandum, King to Seamans, "Actions Since SEPC Meeting of 14-15 July 1960," September 29, 1960.
September 30The 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:
September 30 - October 3Charles J. Donlan of STG, Chairman of the Evaluation Board which would consider contractors' proposals on feasibility studies for an advanced manned spacecraft, invited the Directors of Ames Research Center, Jet Propulsion Laboratory, Flight Research Center, Lewis Research Center, Langley Research Center, and Marshall Space Flight Center to name representatives to the Evaluation Board.

The Technical Assessment Panels began evaluation of contractors' proposals on October 10."Participating Companies or Company Teams," partial set of material for Evaluation Board use; "Apollo Spacecraft Chronology," unpublished, annotated by Robert O. Piland, p. 4.
October 17In 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." Memorandum, Low to Director of Space Flight Programs, "Manned Lunar Landing Programs," October 17, 1960.
October 21A staff meeting of STG's Flight Systems Division was held to fix additional design constraints for the in- house design study of the Apollo spacecraft.Fundamental decisions were made as a result of this and a previous meeting on September 20:

October 28Key staff members of NASA Headquarters and the Commander, U.S. Air Force Research and Development Command, met at the Air Force Ballistic Missile Division, Los Angeles, Calif., to attend briefings and discuss matters of mutual concern.At an executive session, Air Force and NASA programs of orbital rendezvous, refueling, and descent from orbit were discussed. Long-range Air Force studies on a lunar base were in progress as well as research on more immediate missions, such as rendezvous by an unmanned satellite interceptor for inspection purposes, manned maintenance satellites, and reentry methods. NASA plans for the manned lunar landing mission included the possible use of the Saturn booster in an orbital staging operation employing orbital refueling. Reentry studies beyond Mercury were concentrated on reentry at escape speeds and on a spacecraft configuration capable of aerodynamic maneuvering during reentry. Memorandum, Donald H. Heaton, Assistant Administrator for Resources, for the Record, "Minutes of the Executive Meeting at AFBMD on October 28, 1960," November 2, 1960.
November 3The Department of the Interior announced that the U.S. Geological Survey would undertake detailed studies of lunar geology as part of a new $205,000 program in astrogeology financed by NASA. The program would include geological analysis of photographs of selected areas on the moon, terrestrial crater studies, and investigations into the origin of tektites, meteorites, and related material of possible extraterrestrial origin. Certain lunar features would be studied more closely and larger scale diagrams would be made of specific areas in the vicinity of sites selected by NASA for unmanned spacecraft landings.New York Times, November 9, 1960.
November 4At a meeting, Charles J. Donlan of STG and George M. Low, John H. Disher, Milton W. Rosen, and Elliott Mitchell, all of NASA Headquarters, discussed a plan to set up informal technical liaison groups to broaden the base for inter-Center information exchange on the Apollo program with particular reference to onboard propulsion.Memorandum, Abe Silverstein to Director, Launch Vehicle Programs, "Apollo Technical Liaison Groups," November 29, 1960.
November 8Little Joe 5 with a Mercury production spacecraft was launched from Wallops Island to test the spacecraft in an abort simulating the most severe launch conditions. At 15.4 seconds after liftoff, the escape rocket motor and tower jettison motor ignited prematurely. Booster, capsule, and tower remained mated through ballistic trajectory until destroyed on impact.James M. Grimwood, Project Mercury: A Chronology (NASA SP-4001, 1963), p. 117; Swenson et al., This New Ocean, p. 291.
November 12Discoverer XVII was launched into polar orbit from Vandenberg Air Force Base and the payload was recovered on November 14.

November 21An attempt was made to launch Mercury-Redstone 1 (MR-1) from the Atlantic Missile Range. After a four- or five-inch liftoff, MR-1 launched its escape tower but not the capsule. The undamaged spacecraft was recovered for reuse.Swenson et al., This New Ocean, pp. 293-297.
November 22STG 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:
