Schulz and his American icon Snoopy since Apollo missions began in the 1960s. Schulz created comic strips depicting Snoopy on the Moon, capturing public excitement about America’s achievements in space. In May 1969, Apollo 10 astronauts traveled to the Moon for a final trial run before the lunar landings took place on later missions. Because that mission required the lunar module to skim within 50,000 feet of the Moon’s surface and “snoop around” to determine the landing site for Apollo 11, the crew named the lunar module Snoopy. The command module was named Charlie Brown, after Snoopy’s loyal owner. These books are a united effort between Peanuts Worldwide, NASA and Simon & Schuster to generate interest in space among today’s younger children.

  • Appendix a Apollo 15: “The Problem We Brought Back from the Moon”
    Appendix A Apollo 15: “The Problem We Brought Back From the Moon” Postal Covers Carried on Apollo 151 Among the best known collectables from the Apollo Era are the covers flown onboard the Apollo 15 mission in 1971, mainly because of what the mission’s Lunar Module Pilot, Jim Irwin, called “the problem we brought back from the Moon.” [1] The crew of Apollo 15 carried out one of the most complete scientific explorations of the Moon and accomplished several firsts, including the first lunar roving vehicle that was operated on the Moon to extend the range of exploration. Some 81 kilograms (180 pounds) of lunar surface samples were returned for anal- ysis, and a battery of very productive lunar surface and orbital experiments were conducted, including the first EVA in deep space. [2] Yet the Apollo 15 crew are best remembered for carrying envelopes to the Moon, and the mission is remem- bered for the “great postal caper.” [3] As noted in Chapter 7, Apollo 15 was not the first mission to carry covers. Dozens were carried on each flight from Apollo 11 onwards (see Table 1 for the complete list) and, as Apollo 15 Commander Dave Scott recalled in his book, the whole business had probably been building since Mercury, through Gemini and into Apollo. [4] People had a fascination with objects that had been carried into space, and that became more and more popular – and valuable – as the programs progressed. Right from the start of the Mercury program, each astronaut had been allowed to carry a certain number of personal items onboard, with NASA’s permission, in 1 A first version of this material was issued as Apollo 15 Cover Scandal in Orbit No.

  • 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.

  • Charles M. Duke, Jr
    ORAL HISTORY TRANSCRIPT CHARLES M. DUKE, JR. INTERVIEWED BY DOUG WARD HOUSTON, TEXAS – 12 MARCH 1999 VOICE OFF CAMERA: And we’re recording. WARD: Well this is our oral history interview with Charles Duke, Apollo astronaut. The date is March 12, 1999. And, Charlie, one of the things that struck me in going back over some of the information on your career was the number of you guys who came into the Astronaut corps from Eagle Scout backgrounds. I think I counted—at last count there were 293 current and former astronauts. Forty of you had been Eagle Scouts, including you. Is that a cause-and-effect sort of a relationship? Or do you think it’s just that people who excel in one thing tend to excel in all of them? DUKE: I think there’s probably some connection, Doug. It might be slight. Some connection. I learned in Scouts responsibility, dedication, perseverance, goal-setting, patriotism, all of those things, I think, that led me to a career in the military. And from that background in the military, then, I was starting my military career and the space program was getting started, all of those attributes and characteristics that had been foundational in my life through the Scouts, I think, certainly helped me in my military career and then focused me in the right direction for the space program. I was in flying school in 1957, and I’d just soloed in October when they launched the Sputnik. And, you know, beginning of the space age. And 4 years later, of course, [Yuri A.] Gagarin and then [Alan B.] Shepard [Jr.] went up, and I was still a lieutenant in Germany in a fighter squadron, and began to dream at that point about, you know, “Maybe this career I’m on, if I set the right goals, I could be an astronaut one day.” And so that’s what happened.

Muehlberger The University of Texas at Austin, Austin, Texas 78712 Friedrich Horz Geology Branch, NASA Johnson Space Center, Houston, Texas 77058 J. R. Sevier Lunar and Planetary Institute, Houston, Texas 77058 G. E. Ulrich U.S. Geological Survey, Flagstaff, Arizona 86001 Summary-This document is a committee report which outlines scientific objectives and specific rationales developed for the exploration of the Apollo 16 site, our most important mission to the lunar highlands. Although premission hypotheses erroneously favored a volcanic origin for the Cayley plains as well as Descartes Mountains, the major mission objectives were successfully accomplished: to delineate the nature and origin of two major physiographic units of the lunar central highlands. The units are composed of fragmental impact deposits; present debate focuses on specific source areas of the samples and depositional mechanism(s). The premission exploration strategy was to use impact craters of various diameters and associated depths of penetration as stratigraphic probes. Specific sampling procedures, operational constraints, and suites of samples that were collected for specific local objectives, are described for lunar scientists who are unfamiliar with mission planning in general and more specifically with Apollo 16. A large number of samples taken to reconstruct local stratigraphic-structural relationships are either insuffi- ciently studied or have not been studied at all. While such stratigraphic-structural relationships are extremely complex, or even chaotic, at Apollo 16, additional insight into local geologic processes could be obtained by future investigation of these special sample suites.
