  • Apollo Program 1 Apollo Program
    Apollo program 1 Apollo program The Apollo program was the third human spaceflight program carried out by the National Aeronautics and Space Administration (NASA), the United States' civilian space agency. First conceived during the Presidency of Dwight D. Eisenhower as a three-man spacecraft to follow the one-man Project Mercury which put the first Americans in space, Apollo was later dedicated to President John F. Kennedy's national goal of "landing a man on the Moon and returning him safely to the Earth" by the end of the 1960s, which he proposed in a May 25, 1961 address to Congress. Project Mercury was followed by the two-man Project Gemini (1962–66). The first manned flight of Apollo was in 1968 and it succeeded in landing the first humans on Earth's Moon from 1969 through 1972. Kennedy's goal was accomplished on the Apollo 11 mission when astronauts Neil Armstrong and Buzz Aldrin landed their Lunar Module (LM) on the Moon on July 20, 1969 and walked on its surface while Michael Collins remained in lunar orbit in the command spacecraft, and all three landed safely on Earth on July 24. Five subsequent Apollo missions also landed astronauts on the Moon, the last in December 1972. In these six spaceflights, 12 men walked on the Moon. Apollo ran from 1961 to 1972, and was supported by the two-man Gemini program which ran concurrently with it from 1962 to 1966. Gemini missions developed some of the space travel techniques that were necessary for the success of the Apollo missions.

  • The Following Are Edited Excerpts from Two Interviews Conducted with Dr
    Interviews with Dr. Wernher von Braun Editor's note: The following are edited excerpts from two interviews conducted with Dr. Wernher von Braun. Interview #1 was conducted on August 25, 1970, by Robert Sherrod while Dr. von Braun was deputy associate administrator for planning at NASA Headquarters. Interview #2 was conducted on November 17, 1971, by Roger Bilstein and John Beltz. These interviews are among those published in Before This Decade is Out: Personal Reflections on the Apollo Program, (SP-4223, 1999) edited by Glen E. Swanson, whick is vailable on-line at http://history.nasa.gov/SP-4223/sp4223.htm on the Web. Interview #1 In the Apollo Spacecraft Chronology, you are quoted as saying "It is true that for a long time we were not in favor of lunar orbit rendezvous. We favored Earth orbit rendezvous." Well, actually even that is not quite correct, because at the outset we just didn't know which route [for Apollo to travel to the Moon] was the most promising. We made an agreement with Houston that we at Marshall would concentrate on the study of Earth orbit rendezvous, but that did not mean we wanted to sell it as our preferred scheme. We weren't ready to vote for it yet; our study was meant to merely identify the problems involved. The agreement also said that Houston would concentrate on studying the lunar rendezvous mode. Only after both groups had done their homework would we compare notes. This agreement was based on common sense. You don't start selling your scheme until you are convinced that it is superior.

Apollo 1, known at that time as AS (Apollo Saturn)-204 would be the first manned spaceflight of the Apollo program, and would launch a few months after the flight of Gemini 12, which had occurred on 11 November 1966. Although Gemini 12 was a short duration flight, Pilot Buzz Aldrin had performed three extensive EVA’s (Extra Vehicular Activities), proving that Astronauts could work for long periods of time outside the spacecraft.

  • 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.

  • The Apollo Lunar Orbit Rendezvous Architecture Decision Revisited
    Student Session II Paper No. GT-SSEC.E.2 The Apollo Lunar Orbit Rendezvous Architecture Decision Revisited David M. Reeves1 Georgia Institute of Technology National Institute of Aerospace, Hampton, VA, 23666 Michael D. Scher2 University of Maryland National Institute of Aerospace, Hampton, VA, 23666 Dr. Alan W. Wilhite3 Georgia Institute of Technology National Institute of Aerospace, Hampton, VA, 23666 Dr. Douglas O. Stanley4 Georgia Institute of Technology National Institute of Aerospace, Hampton, VA, ABSTRACT The 1962 Apollo architecture mode decision process was revisited with modern analysis and systems engineer tools to determine driving selection criteria and technology/operational mode design decisions that may be used for NASA’s current Space Exploration program. Results of the study agreed with the Apollo selection of the Lunar Orbit Rendezvous mode based on the technology maturity and politics in 1962. Using today’s greater emphasis on human safety and improvements in technology and design maturity, a slight edge may be given to the direct lunar mode over lunar orbit rendezvous. Also, the NOVA direct mode and Earth orbit rendezvous mode are not competitive based any selection criteria. Finally, reliability and development, operations, and production costs are major drivers in today’s decision process. 1Graduate Research Assistant, Georgia Institute of Technology, 100 Exploration Way, AIAA Student Member. 2 Graduate Research Assistant, University of Maryland, 100 Exploration Way, AIAA Student Member. 3 Langley Professor, Georgia Institute of Technology, 100 Exploration Way, AIAA Associate Fellow. 4 Langley Professor, Georgia Institute of Technology, 100 Exploration Way, AIAA Member.

The large windows were later replaced with smaller, down-facing windows. Seats also were removed resulting in a design in which the astronauts stand. NASA Administrator James Webb, Vice President Lyndon Johnson, Dr. Robert Gilruth, director of NASA's Manned Spacecraft Center (now Johnson Space Center) in Houston, and others participate in the activity on Sept. 12, 1962. Credits: White House/Cecil Stoughton On July 24, 1962, Dr. John Houbolt explains his lunar orbit rendezvous concept for landing on the Moon. His approach called for a separate lander which saved weight from the "direct ascent" design in which the entire spacecraft landed on the lunar surface.

  • Using the Space Program from Mercury to Apollo As Portrayed In
    Using the Space Program from Mercury to Apollo as Portrayed in the Movies The Right Stuff and Apollo 13 and in the Mini‐series From the Earth to the Moon as a Teaching Tool James G. Goll Department of Chemistry, Geoscience and Physics Edgewood College, Madison, WI 53711 [email protected] Abstract This chapter will examine how popular media related to the space program can be used to demonstrate the nature and motivation of scientific inquiry and science concepts. For over fifty years, the space program has inspired students of science and engineering. The United States manned space program from project Mercury to Apollo is the subject of two movies, The Right Stuff and Apollo 13, and the mini‐series From the Earth to the Moon. Many documentary style television productions are available to supplement these movies and the miniseries. These documentaries provide recollections from astronauts, flight controllers, and flight directors. Moonshot and To the Moon chronicle the manned space program during the Mercury, Gemini, and Apollo programs. The documentary To the Edge and Back inspired the movie, Apollo13. The Science Channel’s Moon Machines show many behind‐the‐scenes people who made the trips to the moon possible. The History Channel used the manned space program as a subject for several of its series: Man, Moment, and Machine, Modern Marvels, 20th Century with Mike Wallace, and Failure is Not an Option. Introduction The movie Apollo13 (1995) and the follow‐up miniseries From the Earth to the Moon (1998), have been used to teach many chemistry concepts (1‐5). Apollo 13 has been shown to produce both high impact upon audiences and high utility for instructors when used as a teaching tool (6).

  • Lessons from the Lunar Module Program: the Director’S Conclusions
    70th International Astronautical Congress, Washington, DC. Copyright ©2019 by Andrew S. Erickson. All rights reserved. IAC-19,E4,3,7,x53535 LESSONS FROM THE LUNAR MODULE PROGRAM: THE DIRECTOR’S CONCLUSIONS Dr. Andrew S. Erickson* Visiting Scholar, John King Fairbank Center for Chinese Studies, Harvard University Professor of Strategy, United States Naval War College [email protected] * The views expressed in this article are those of the author alone, who welcomes all possible comments and suggestions for improvement via <http://www.andrewerickson.com/contact/>. They do not represent the estimates or policies of the U.S. Navy or any other organization of the U.S. Government. The highlight of Joseph Gavin Jr’s distinguished career as an aerospace engineer and leader was serving as Apollo Lunar Module (LM) Program Director from 1962-72. Gavin believed the Apollo Program “would be the biggest engineering job of history. bigger than building the pyramids or inventing the airplane and would take every ounce of ingenuity. to pull off.” In it, Gavin led as many as 7,500 employees in developing the LM and ultimately building twelve operational vehicles. All met mission requirements, and those that were used worked every time. “For the 1960s, that was the place to be, that was the program to be involved with,” he later reflected. “As tough as it was, none of us would have chosen not to be there.” Developing the state-of-the-art machine required multiple unprecedented innovations and maximization of reliability amid inherently imperfect testing conditions. When congratulated on the success of each LM landing, Gavin typically replied that he would not be happy until his spacecraft and its crew got off the moon.

    Enchanted Rendezvous John C. Houbolt and the Genesis of the Lunar-Orbit Rendezvous Concept Enchanted Rendezvous: John C. Houbolt and the Genesis of the Lunar-Orbit Rendezvous Concept by James R. Hansen NASA History Office Code Z NASA Headquarters Washington DC 20546 MONOGRAPHS IN AEROSPACE HISTORY SERIES #4 December 1995 Foreword One of the most critical technical decisions made during the conduct of Project Apollo was the method of flying to the Moon, landing on the surface, and returning to Earth. Within NASA during this debate, several modes emerged. The one eventually chosen was lunar-orbit rendezvous (LOR), a proposal to send the entire lunar spacecraft up in one launch. It would head to the Moon, enter into orbit, and dispatch a small lander to the lunar surface. It was the simplest of the various methods, both in terms of development and operational costs, but it was risky. Because rendezvous would take place in lunar, instead of Earth, orbit, there was no room for error or the crew could not get home. Moreover, some of the trickiest course corrections and maneuvers had to be done after the spacecraft had been committed to a circumlunar flight. Between the time of NASA's conceptualization of the lunar landing program and the decision in favor of LOR in 1962, a debate raged among the advocates of the various methods. John C. Houbolt, an engineer at the Langley Research Center in Hampton, Virginia, was one of the most vocal of those supporting LOR and his campaign in 1961 and 1962 helped shape the deliberations in a fundamental way.
