The Soviet Union launched into orbit the five-ton Vostok I, with Yuri A. Gagarin as pilot, the first man to make a successful orbital space flight. The payload included life-support equipment and radio and television to relay information on the condition of the pilot. The spacecraft apogee was 187.8 miles, the perigee was 109.5 miles, inclination 65.07 degrees, and the orbital period 89.1 minutes. After a 108-minute, one-orbit flight, the capsule and pilot reentered and landed safely in the Soviet Union.

President John F. Kennedy, in his regular press conference, stated that "no one is more tired than I am" of seeing the United States second to Russia in space. "They secured large boosters which have led to their being first in Sputnik, and led to their first putting their man in space. We are, I hope, going to be able to carry out our efforts, with due regard to the problem of the life of the men involved, this year. But we are behind . . . the news will be worse before it is better, and it will be some time before we catch up. . . ."

Washington Post, April 13, 1961.

April 14

Under questioning by the House Committee on Science and Astronautics, NASA Associate Administrator Robert C. Seamans, Jr., stated that a landing on the moon in 1967 might be possible through an all-out crash program at a cost of $4 to $5 billion a year instead of the current budget of $1.236 billion.

A circular, "Manned Lunar Landing via Rendezvous," was prepared by John C. Houbolt from material supplied by himself, John D. Bird, Max C. Kurbjun, and Arthur W. Vogeley, who were members of the Langley Research Center space station subcommittee on rendezvous. Other members of the subcommittee at various times included W. Hewitt Phillips, John M. Eggleston, John A. Dodgen, and William D. Mace.

Bird, "Short History of the Development of the Lunar Orbit Rendezvous Plan at Langley Research Center," p. 3.

April 19

John C. Houbolt and members of the Langley Research Center subcommittee on rendezvous outlined the objectives of a rendezvous program that would lead ultimately to a manned lunar landing:

  1. establish manned and unmanned orbital operations,
  2. establish techniques for accomplishing space missions through the orbital assembly of units.
Three key projects were described which would accomplish these objectives. The first was MORAD (Manned Orbital Rendezvous and Docking). which would require the use of the Mercury-Atlas and Scout in the 1961- 1963 period. Rendezvous in space between the Mercury spacecraft and Scout payload would establish confidence in manned rendezvous techniques and lead to simplification of equipment and increased reliability. The second key project was ARP (Apollo Rendezvous Phases), in which the Atlas, Agena, and Saturn boosters would be used in the 1962-1965 period. This program would accomplish rendezvous with space stations, personnel transfer, resupply of space laboratory, execution of space maneuvers after coupling (steps toward lunar landing), and development of specifications for subsequent orbital and moon missions. The third project was called MALLIR (Manned Lunar Landing Involving Rendezvous), in which Saturn and Apollo components would be used during the 1961-1967 period. After qualification of the Saturn components for rendezvous operations, an early manned lunar landing would take place.

Langley Research Center, "Manned Lunar Landing via Rendezvous," April 19, 1961.

April 19

Early LEM model

An early lunar excursion module was proposed by personell of Langley Research Center as the lunar lander for the suggested Project MALLIR.


The booster requirements for Project MALLIR (Manned Lunar Landing Involving Rendezvous) would be satisfied by use of the Saturn C-2 as the basic launch vehicle. The number of boosters needed to achieve a lunar landing would be substantially reduced by using a combination of earth orbit and lunar orbit rendezvous. In a Project MALLIR configuration, two Saturn C-2's would be required. The first would launch the command module, lunar lander, and propulsion unit for lunar braking. The second would launch a booster which would rendezvous in earth orbit with the spacecraft. This booster would be jettisoned after launching the configuration into a lunar trajectory. After reaching lunar orbit, the lunar lander would separate from the command module and descend to the lunar surface. One man would remain behind in the command module orbiting the moon. After a brief lunar stay, the two men would ascend in the lunar lander and rendezvous with the command module. The command module would then boost to return trajectory, leaving behind the lunar lander, and reenter after jettisoning the propulsion unit. The command module was estimated to weigh 11,000 pounds, and the lunar lander 11,000 pounds.

April 20

A conference was held at NASA Headquarters on the relationship between the Prospector and Apollo programs. Representatives of the Jet Propulsion Laboratory (JPL) and STG discussed the possible redirection of Prospector planning to support more directly the manned space program. The Prospector spacecraft was intended to soft-land about 2,500 pounds on the lunar surface with an accuracy of +/-1 kilometer anywhere on the visible side of the moon. An essential feature of Prospector was the development of an automatic roving vehicle weighing about 1500 pounds which would permit detailed reconnaissance of the lunar surface over a wide area. STG representatives felt that the most useful feature of the Prospector program lay in its planned ability to soft-land cargo in close proximity to a desired site. Many applications could be foreseen, such as the deposit of landing aids and essential material in support of a manned lunar landing or in continuing support for a manned lunar expedition. However, the Prospector roving vehicle seemed to be a much more complicated and heavier piece of hardware than a manned lunar transport and, for that reason, STG did not support its development. The planning for Prospector involved JPL in-house studies concerning closer integration with manned space flight requirements, definitive decisions on the program within several months, a contractor's study in Fiscal Year 1962, engineering design in Fiscal Year 1963, and a hardware contract at a future date. Future Prospector planning would emphasize its cargo-carrying ability as a prime requirement, JPL representatives stated.

Mercury-Atlas 3 (MA-3) was launched from the Atlantic Missile Range, carrying a "mechanical astronaut" in an intended unmanned orbital flight. Forty seconds after liftoff, MA-3 was destroyed by the range safety officer because the inertial guidance system had failed to pitch the vehicle over toward the horizon. The spacecraft successfully aborted and was recovered a short distance off shore.

April 25

A conference was held at Lewis Research Center between STG and Lewis representatives to discuss the research and development contract for the liquid-hydrogen liquid-oxygen fuel cell as the primary spacecraft electrical power source. Lewis had been provided funds approximately $300,000 by NASA Headquarters to negotiate a contract with Pratt & Whitney Aircraft Division of United Aircraft Corporation for the development of a fuel cell for the Apollo spacecraft. STG and Lewis representatives agreed that the research and development should be directed toward the liquid-hydrogen - liquid-oxygen fuel cell. Guidelines were provided by STG:

Lewis planned to request a pilot model of the fuel cell of about 250 watts capacity, capable of unattended operation. Contract negotiations were expected to be completed by May 2 and the model delivered within 12 months of the contract award.

C-2 mission possibilities

The engineering sketch drawn by John D. Bird of Langley Research Center on May 3, 1961, indicated the thinking of that period: By launching two Saturn C-2's, the lunar landing mission could be accomplished by using both earth rendezvous and lunar rendezvous at various stages of the mission.


May 5

STG completed the first draft of "Project Apollo, Phase A, General Requirements for a Proposal for a Manned Space Vehicle and System" [Statement of Work], an early step toward the spacecraft specification. A circumlunar mission was the basis for planning.

In the first American manned space flight, Freedom 7, piloted by Astronaut Alan B. Shepard, Jr., was launched successfully from the Atlantic Missile Range. The Redstone rocket boosted the Mercury capsule to 116.5 miles and a maximum speed of 5,180 miles per hour. After a flight of 15 minutes and 22 seconds, the landing was made 302 miles downrange from the launch site. Recovery operations were perfect; there was no damage to the spacecraft; and Astronaut Shepard was in excellent condition.

May 7

Albert C. Hall of The Martin Company proposed to Robert C. Seamans, Jr., NASA's Associate Administrator, that the Titan II be considered as a launch vehicle in the lunar landing program. Although skeptical, Seamans arranged for a more formal presentation the next day. Abe Silverstein, NASA's Director of Space Flight Programs, was sufficiently impressed to ask Director Robert R. Gilruth and STG to study the possible uses of Titan II. Silverstein shortly informed Seamans of the possibility of using the Titan II to launch a scaled-up Mercury spacecraft.

In a special message to Congress on urgent national needs, President John F. Kennedy called for new, long- range goals for the space program: "Now it is time to take longer strides - time for a great new American enterprise time for this nation to take a clearly leading role in space achievement, which in many ways may hold the key to our future on earth. . . . I believe that this nation should commit itself to achieving the goal, before this decade is out, of landing a man on the moon and returning him safely to the earth. No single space project in this period will be more impressive to mankind, or more important for the long-range exploration of space; and none will be so difficult or expensive to accomplish . . . in a very real sense, it will not be one man going to the moon if we make this judgment affirmatively, it will be an entire nation. For all of us must work to put him there." The President also called for the early development of the Rover nuclear rocket, the acceleration of the use of space satellites for worldwide communications, and the development of a weather satellite system. For these and associated projects in space technology, the President requested additional appropriations totaling $611 million for NASA and DOD for Fiscal Year 1962.

June 7

A preliminary study of a fin-stabilized solid-fuel rocket booster, the Little Joe Senior, was completed by members of STG. The booster would be capable of propelling a full-size Apollo reentry spacecraft to velocities sufficient to match critical portions of the Saturn trajectory. The purpose was to provide a simple and fairly inexpensive means of determining, from flight tests, full-scale configuration concepts, systems hardware performance, and vehicle structural integrity. Of particular importance would be the flight testing of the Apollo spacecraft escape system under simulated maximum conditions. (On April 6, 1962, NASA submitted a Request for Proposal to bidders on the Little Joe Senior, by that time renamed Little Joe II.)

'The Lundin Committee completed its study of various vehicle systems for the manned lunar landing mission, as requested on May 25 by NASA associate Administrator Robert C. Seamans, Jr. The Committee had considered alternative methods of rendezvous: earth orbit, lunar orbit, a combination of earth and lunar orbit, and lunar surface. Launch vehicles studied were the Saturn C-2 and C-3. The concept of a low- altitude earth orbit rendezvous using two or three C-3's was clearly preferred by the Committee. Reasons for this preference were the small number of launches and orbital operations required and the fact that the Saturn C- 3 was considered to be an efficient launch vehicle of great utility and future growth.

Lundin Committee, "A Survey of Various Vehicle Systems for the Manned Lunar Landing Mission," June 10, 1961.

June 16

The Fleming Committee, which had been appointed on May 2, submitted its report to NASA associate Administrator Robert C. Seamans, Jr., on the feasibility of a manned lunar landing program. The Committee concluded that the lunar mission could be accomplished within the decade. Chief pacing items were the first stage of the launch vehicle and the facilities for testing and launching the booster. It also concluded that information on solar flare radiation and lunar surface characteristics should be obtained as soon as possible, since these factors would influence spacecraft design. Special mention was made of the need for a strong management organization.

Robert C. Seamans, Jr., NASA Associate Administrator, notified the Directors of Launch Vehicle Program, Space Flight Programs, Advanced Research Programs, and Life Sciences Programs that Donald H. Heaton had been appointed Chairman of an Ad Hoc Task Group. It would establish program plans and supporting resources necessary to accomplish the manned lunar landing mission by the use of rendezvous techniques, using the Saturn C-3 launch vehicle, with a target date of 1967. Guidelines and operating methods were similar to those of the Fleming Committee. Members of the Task Group would be appointed from the Offices of Launch Vehicle Programs, Space Flight Program, Advanced Research Programs, and Life Sciences Programs. The work of the Group (Heaton Committee) would be reviewed weekly. The study was completed during August.

June 23

NASA Associate Administrator Robert C. Seamans, Jr., requested Kurt H. Debus, Director of the NASA Launch Operations Directorate, and Maj. Gen. Leighton I. Davis, Commander of the Air Force Missile Test Center, to make a joint analysis of all major factors regarding the launch requirements, methods, and procedures needed in support of an early manned lunar landing. The schedules and early requirements were to be considered in two phases:

  1. in line with the Fleming Report, a direct flight to the moon would be assumed, using the Saturn C-1 and C-3 launch vehicles in early support phases and liquid- or solid-fueled Nova launch vehicles for the lunar landing;
  2. as a possible alternative or parallel program, orbital rendezvous operations using Saturn C-3 and liquid- fueled Nova.
The analysis should include recommendations on mutual NASA-DOD range responsibilities, authority, management structures, and other allied subjects. On June 30, Seamans notified Debus and Davis that the evaluation of tracking and command stations should not be included in the study. He stressed that the factors of immediate concern with regard to launch operations were those of launch site locations, land acquisition requirements, spacecraft and launch vehicle preparation facilities, vehicle launch facilities, and other facilities and requirements at the launch site. (Phase I of the Report was submitted on July 31.)
