The committee met, pursuant to notice, at 10 :05 a.m., in room 2318, Rayburn House Office Building, Ron. George P. Miller, chairman, presiding. The CHAIRMAN.The committee will be in order. Dr. Paine, hfr. Cortright, members of the Apollo 13 Review Board, we are pleased to welcome you to the committee today for the purpose of presenting findings, determinations, and recommendations of the A 0110 13 Review Board. %r. Paine, I would like to commend you for the appointment of a most competent and outstanding board to review the Apollo 13 ac- cident and the circumstances surrounding it. Mr. Cortright, whom this committee knows well, has distinguished himself not only as an administrator in the NASA Headquarters or- ganization but also as a field center director at Langley Research Center. The other members of the board are similarly well qualified to have participated in this intensive and searching review. As I stated at the time of the Apollo 13 accident the committee de- cided that sufficient time should be allowed for NASA to fully investi- gate the accident and at such time that this investi ation was com- pleted the committee would convene to receive NASa ’s evaluation of the accident. Therefore, I have asked you to appear here today even though the board’s report was only submitted to you yesterday, Dr. Paine, because I feel it is important that the members of the committee receive a first- hand and timely review of the Apollo 13 accident. Dr. Paine, I understand you have a short statement and then Mr. Cortright will go into the details of the accident and the board’s findings. I want to give all members an opportunity to ask questions, so will you please proceed. Before proceeding, I would also like to make a part of the record the fact that Mr. Wilson of the staff of the committee was appointed to act as an obsen-er with the boa.rd. I want to thank you for the courtesies you have shown us and it has given us a new system of liaison. Please proceed, Dr. Paine. (1) 2 STATEMENT OF DR. THOMAS 0. PAINE, ADMINISTRATOR, NASA Dr. PAINE.Mr. Chairman and members of the committee, on April 17, Dr. George Low and I established the Apollo 18 Review Board under the direction of Mr. Edgar &I.Cortright, director of the Lang- ley Research Center. The instructions to the board are contained in a memorandum dated April 17, and the membership of the board in a memorandum dated April 20, 1970. ~vhichare reproduced in the sum- mary volume of the report you have received. The past 2 months have involved long hours and very hard work by the review board and supporting elements in NL4SA and the indus- trial community. I would like to take this opportunity to extend my thanks to them for the thoroughness of their investigation and their dedication to this arduous assignment. Since I received the review board report only yesterday, I hare not had a chance to review it in detail. Nor have I had the benefit of the independent assessment which is being carried out by the Aerospace Safety Advisory Panel, chaired by Dr. Charles Harrington. The Office of Manned Space Flight is also conducting a separate review of the report. In about 10 days I will receive the results of the safety panel and the manned space flight review. Until I have received and studied these re- ports. I will obviously not be in a. position to give you my evaluation of the board‘s recommendations or NASA‘s future actions. Earlier re announced a change in our lunar landing schedule in- volving a delay of the Bpollo 14 launch from October to the December launch window. However, this is subject to rei-iexT in light of the re- port of the Apollo 13 Reiyiew Board and we n-ill not fly Apollo 14 to the moon until we are confident that we have done everything necessary to eliminate the conditions that caused or contributed to the problems on Apollo 13. I believe that, as we plan man’s future course in space, the preface to this report should be a reminder of the nature of the challenge rre have undertaken. Let me quote : The Apollo 13 accident, which aborted man’s third mission to explore the sur- face of the moon, is a harsh reminder of the immense difficulty of this under- taking. The total Apollo system of ground complexes, launch vehicle, and spacecraft constitutes the most ambitious and demanding engineering development ever undertaken by man. For these missions to succeed, both men and equipment must perform to near perfection. That this system has already resulted in two success- ful lunar surface explorations is a tribute to those men and women who con- ceived, designed, built, and flew it. Perfection is not only difficult to achieve, but difficult to maintain. The im- perfection in hpollo 13 constituted a near disaster. adverted only by outstanding performance on the part of the crew and the ground control team ivhich sup- ported them. The Board feels that the nature of the Apollo 13 equipment failure ho!ds im- portant lessons rrhich, TThen applied to future missions, will contribute to the safety and effectiveness of manned space flight. Afr, Chairman, there has been time for me to reach one conclusion on the report of the Apollo 13 Review Board, and that is that the board and their supporting teams have done a. magnificent piece of technical detective work that carefully reconstructs the background and the events xhich took place aboard Apollo 13 800,000 miles from earth. 3 1 JT-ould110~ like to introduce the chairman of the rerieJT board, Mr. Edgar Cortright, who will briefly discuss the report and respond to your questions. The CH~IIRMAX.Thank you T-ery much, Dr. Paine. FFTe are very happy to have you here, Mr. Cortright. STATEMENT OF EDGAR M.

Cannon NASA Marshall Space Flight Center, Huntsville, Alabama Corey Brown Aerojet-Rocketdyne, West Palm Beach, Florida 12.1 Introduction Earth to orbit launch vehicles are propelled by rocket engines and motors, both liquid and solid. This chapter will discuss liquid engines. The heart of a launch vehicle is its engine. The remainder of the vehicle (with the notable exceptions of the payload and guidance system) is an aero structure to support the propellant tanks which provide the fuel and oxidizer to feed the engine or engines. The basic principle behind a rocket engine is straightforward. The engine is a means to convert potential thermochemical energy of one or more propellants into exhaust jet kinetic energy. Fuel and oxidizer are burned in a combustion chamber where they create hot gases under high pressure. These hot gases are allowed to expand through a nozzle. The molecules of hot gas are first constricted by the throat of the nozzle (de-Laval nozzle) which forces them to accelerate; then as the nozzle flares outwards, they expand and further accelerate. It is the mass of the combustion gases times their velocity, reacting against the walls of the combustion chamber and nozzle, which produce thrust according to Newton’s third law: for every action there is an equal and opposite reaction. [1] Solid rocket motors are cheaper to manufacture and offer good values for their cost.

  • Project Apollo: Americans to the Moon 440 Document II-1 Document Title
    440 Project Apollo: Americans to the Moon Document II-1 Document Title: NASA, “ Minutes of Meeting of Research Steering Committee on Manned Space Flight,” 25–26 May 1959. Source: Folder 18675, NASA Historical Reference Collection, History Division, NASA Headquarters, Washington, DC. Within less than a year after its creation, NASA began looking at follow-on programs to Project Mercury, the initial human spacefl ight effort. A Research Steering Committee on Manned Space Flight was created in spring 1959; it consisted of top-level representatives of all of the NASA fi eld centers and NASA Headquarters. Harry J. Goett from Ames, but soon to be head of the newly created Goddard Space Flight Center, was named chair of the committee. The fi rst meeting of the committee took place on 25 and 26 May 1959, in Washington. Those in attendance provided an overview of research and thinking related to human spacefl ight at various NASA centers, the Jet Propulsion Laboratory (JPL), and the High Speed Flight Station (HSFS) at Edwards Air Force Base. George Low, then in charge of human spacefl ight at NASA Headquarters, argued for making a lunar landing NASA’s long-term goal. He was backed up by engineer and designer Maxime Faget of the Space Task Group of the Langley Research Center and Bruce Lundin of the Lewis Research Center. After further discussion at its June meeting, the Committee agreed on the lunar landing objective, and by the end of the year a lunar landing was incorporated into NASA’s 10-year plan as the long-range objective of the agency’s human spacefl ight program.

  • Apollo Over the Moon: a View from Orbit (Nasa Sp-362)
    chl APOLLO OVER THE MOON: A VIEW FROM ORBIT (NASA SP-362) Chapter 1 - Introduction Harold Masursky, Farouk El-Baz, Frederick J. Doyle, and Leon J. Kosofsky [For a high resolution picture- click here] Objectives [1] Photography of the lunar surface was considered an important goal of the Apollo program by the National Aeronautics and Space Administration. The important objectives of Apollo photography were (1) to gather data pertaining to the topography and specific landmarks along the approach paths to the early Apollo landing sites; (2) to obtain high-resolution photographs of the landing sites and surrounding areas to plan lunar surface exploration, and to provide a basis for extrapolating the concentrated observations at the landing sites to nearby areas; and (3) to obtain photographs suitable for regional studies of the lunar geologic environment and the processes that act upon it. Through study of the photographs and all other arrays of information gathered by the Apollo and earlier lunar programs, we may develop an understanding of the evolution of the lunar crust. In this introductory chapter we describe how the Apollo photographic systems were selected and used; how the photographic mission plans were formulated and conducted; how part of the great mass of data is being analyzed and published; and, finally, we describe some of the scientific results. Historically most lunar atlases have used photointerpretive techniques to discuss the possible origins of the Moon's crust and its surface features. The ideas presented in this volume also rely on photointerpretation. However, many ideas are substantiated or expanded by information obtained from the huge arrays of supporting data gathered by Earth-based and orbital sensors, from experiments deployed on the lunar surface, and from studies made of the returned samples.

  • 4. Lunar Architecture
    4. Lunar Architecture 4.1 Summary and Recommendations As defined by the Exploration Systems Architecture Study (ESAS), the lunar architecture is a combination of the lunar “mission mode,” the assignment of functionality to flight elements, and the definition of the activities to be performed on the lunar surface. The trade space for the lunar “mission mode,” or approach to performing the crewed lunar missions, was limited to the cislunar space and Earth-orbital staging locations, the lunar surface activities duration and location, and the lunar abort/return strategies. The lunar mission mode analysis is detailed in Section 4.2, Lunar Mission Mode. Surface activities, including those performed on sortie- and outpost-duration missions, are detailed in Section 4.3, Lunar Surface Activities, along with a discussion of the deployment of the outpost itself. The mission mode analysis was built around a matrix of lunar- and Earth-staging nodes. Lunar-staging locations initially considered included the Earth-Moon L1 libration point, Low Lunar Orbit (LLO), and the lunar surface. Earth-orbital staging locations considered included due-east Low Earth Orbits (LEOs), higher-inclination International Space Station (ISS) orbits, and raised apogee High Earth Orbits (HEOs). Cases that lack staging nodes (i.e., “direct” missions) in space and at Earth were also considered. This study addressed lunar surface duration and location variables (including latitude, longi- tude, and surface stay-time) and made an effort to preserve the option for full global landing site access. Abort strategies were also considered from the lunar vicinity. “Anytime return” from the lunar surface is a desirable option that was analyzed along with options for orbital and surface loiter.
