Status of Exploration Initiatives: • Is NASA’s strategy in designing the Orion CEV to first service the ISS and then upgrading it to enable lunar missions the most cost-effective approach? That is, is the upgrade approach, rather than designing a crewed vehicle ca- pable of both missions at the onset, the most cost-effective approach? • What is the status of NASA’s Exploration Program and associated projects? • What would be the effect on the March

Nield, Associate Administrator for Commercial Space Transportation at the Federal Aviation Administration (FAA), addressed the future of commercial space travel: “There is tangible work underway by a number of companies aiming for space, partly because of their dreams, but primarily because they are confident it can be done by the private sector and it can be done at a profit.” Indeed, private companies and entrepreneurs are currently aiming to make this dream a reality. While the current economic downturn will likely slow industry progress, space tourism, currently in its infancy, is poised to become a significant part of the hospitality industry. Unlike the space race of the 1950s and 1960s between the United States and the former Soviet Union, the current rivalry is not defined on a national level, but by a collection of first-mover entrepreneurs that are working to define the industry and position it for long- term profitability.

  • 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 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.

  • Challenger Accident in a Rogers Commission Hearing at KSC
    CHALLENGER By Arnold D. Aldrich Former Program Director, NSTS August 27, 2008 Recently, I was asked by John Shannon, the current Space Shuttle Program Manager, to comment on my experiences, best practices, and lessons learned as a former Space Shuttle program manager. This project is part of a broader knowledge capture and retention initiative being conducted by the NASA Johnson Space Center in an “oral history” format. One of the questions posed was to comment on some of the most memorable moments of my time as a Space Shuttle program manager. Without question, the top two of these were the launch of Challenger on STS‐51L on January 28, 1986, and the launch of Discovery on STS‐26 on September 29, 1988. Background The tragic launch and loss of Challenger occurred over 22 years ago. 73 seconds into flight the right hand Solid Rocket Booster (SRB) broke away from the External Tank (ET) as a result of a burn‐ through in its aft most case to case joint and the Space Shuttle vehicle disintegrated resulting in the total loss of the vehicle and crew. The events leading up to that launch are still vivid in my mind and deeply trouble me to this day, as I know they always will. This paper is not about what occurred during the countdown leading up to the launch – those facts and events were thoroughly investigated and documented by the Rogers Commission. Rather, what I can never come to closure with is how we, as a launch team, and I, as one of the leaders of that team, allowed the launch to occur.

This oral history interview is being conducted with Dr. Farouk El-Baz in Boston, Massachusetts, for the Johnson Space Center Oral History Project. Interviewer is Rebecca Wright, assisted by Jennifer Ross-Nazzal. We certainly would like to start by telling you thank you. We know you‘re a very busy person with a very busy schedule, so thank you for finding time for us today. EL-BAZ: You‘re welcome to come here, because this is part of the history of the United States. It‘s important that we all chip in. WRIGHT: We‘re glad to hear that. We know your work with NASA began as early as 1967 when you became employed by Bellcomm [Incorporated]. Could you share with us how you learned about that opportunity and how you made that transition into becoming an employee there? EL-BAZ: Just the backdrop, I finished my PhD here in the US. First job offer was from Germany. It was in June 1964; I was teaching there [at the University of Heidelberg] until December 1965. I went to Egypt then, tried to get a job in geology. I was unable for a whole year, so I came back to the US as an immigrant in the end of 1966. For the first three months of 1967, I began to search for a job. When I arrived in the winter, most of the people that I knew 2 November 2009 1 Johnson Space Center Oral History Project Farouk El-Baz were at universities, and most universities had hired the people that would teach during the year.
