America's First Moon Landing
America’s First Moon Landing (July 21, 1969) Apollo 11, which was launched into his oval mural commemorating America’s Moon landing space from the Kennedy Space Center, embellishes the Brumidi Corridors in the Senate wing of the Florida, began its epic voyage to the Moon on July 16, 1969. On board were Capitol. The mural’s three main elements are: the rocket that Commander Neil A. Armstrong, Lunar propelled the astronauts into orbit; astronauts Neil Armstrong Module Pilot Edwin E. ”Buzz“ Aldrin, Jr., and Buzz Aldrin planting the United States flag on the Moon, and Command Module Pilot Michael with the lunar module Eagle in the background and the space capsule Collins.

Duke, Director of the Solar System Exploration Division of the NASA Johnson Space Center. At a meeting of the Lunar and Planetary Sample Team (LAPST), Dr. Duke (at the time also Science Director of the Office of Exploration, NASA Headquarters) suggested that future lunar geoscience activities had not been planned systematically and that geoscience goals for the lunar base program were not articulated well. LAPST is a panel that advises NASA on lunar sample allocations and also serves as an advocate for lunar science within the planetary science community. LAPST took it upon itself to organize some formal geoscience planning for a lunar base by creating a document that outlines the types of missions and activities that are needed to understand the Moon and its geologic history. -
USGS Open-File Report 2005-1190, Table 1
TABLE 1 GEOLOGIC FIELD-TRAINING OF NASA ASTRONAUTS BETWEEN JANUARY 1963 AND NOVEMBER 1972 The following is a year-by-year listing of the astronaut geologic field training trips planned and led by personnel from the U.S. Geological Survey’s Branches of Astrogeology and Surface Planetary Exploration, in collaboration with the Geology Group at the Manned Spacecraft Center, Houston, Texas at the request of NASA between January 1963 and November 1972. Regional geologic experts from the U.S. Geological Survey and other governmental organizations and universities s also played vital roles in these exercises. [The early training (between 1963 and 1967) involved a rather large contingent of astronauts from NASA groups 1, 2, and 3. For another listing of the astronaut geologic training trips and exercises, including all attending and the general purposed of the exercise, the reader is referred to the following website containing a contribution by William Phinney (Phinney, book submitted to NASA/JSC; also http://www.hq.nasa.gov/office/pao/History/alsj/ap-geotrips.pdf).] 1963 16-18 January 1963: Meteor Crater and San Francisco Volcanic Field near Flagstaff, Arizona (9 astronauts). Among the nine astronaut trainees in Flagstaff for that initial astronaut geologic training exercise was Neil Armstrong--who would become the first man to step foot on the Moon during the historic Apollo 11 mission in July 1969! The other astronauts present included Frank Borman (Apollo 8), Charles "Pete" Conrad (Apollo 12), James Lovell (Apollo 8 and the near-tragic Apollo 13), James McDivitt, Elliot See (killed later in a plane crash), Thomas Stafford (Apollo 10), Edward White (later killed in the tragic Apollo 1 fire at Cape Canaveral), and John Young (Apollo 16). -

Glossary Glossary
Glossary Glossary Albedo A measure of an object’s reflectivity. A pure white reflecting surface has an albedo of 1.0 (100%). A pitch-black, nonreflecting surface has an albedo of 0.0. The Moon is a fairly dark object with a combined albedo of 0.07 (reflecting 7% of the sunlight that falls upon it). The albedo range of the lunar maria is between 0.05 and 0.08. The brighter highlands have an albedo range from 0.09 to 0.15. Anorthosite Rocks rich in the mineral feldspar, making up much of the Moon’s bright highland regions. Aperture The diameter of a telescope’s objective lens or primary mirror. Apogee The point in the Moon’s orbit where it is furthest from the Earth. At apogee, the Moon can reach a maximum distance of 406,700 km from the Earth. Apollo The manned lunar program of the United States. Between July 1969 and December 1972, six Apollo missions landed on the Moon, allowing a total of 12 astronauts to explore its surface. Asteroid A minor planet. A large solid body of rock in orbit around the Sun. Banded crater A crater that displays dusky linear tracts on its inner walls and/or floor. 250 Basalt A dark, fine-grained volcanic rock, low in silicon, with a low viscosity. Basaltic material fills many of the Moon’s major basins, especially on the near side. Glossary Basin A very large circular impact structure (usually comprising multiple concentric rings) that usually displays some degree of flooding with lava. The largest and most conspicuous lava- flooded basins on the Moon are found on the near side, and most are filled to their outer edges with mare basalts. -
Planetary Surfaces
Chapter 4 PLANETARY SURFACES 4.1 The Absence of Bedrock A striking and obvious observation is that at full Moon, the lunar surface is bright from limb to limb, with only limited darkening toward the edges. Since this effect is not consistent with the intensity of light reflected from a smooth sphere, pre-Apollo observers concluded that the upper surface was porous on a centimeter scale and had the properties of dust. The thickness of the dust layer was a critical question for landing on the surface. The general view was that a layer a few meters thick of rubble and dust from the meteorite bombardment covered the surface. Alternative views called for kilometer thicknesses of fine dust, filling the maria. The unmanned missions, notably Surveyor, resolved questions about the nature and bearing strength of the surface. However, a somewhat surprising feature of the lunar surface was the completeness of the mantle or blanket of debris. Bedrock exposures are extremely rare, the occurrence in the wall of Hadley Rille (Fig. 6.6) being the only one which was observed closely during the Apollo missions. Fragments of rock excavated during meteorite impact are, of course, common, and provided both samples and evidence of co,mpetent rock layers at shallow levels in the mare basins. Freshly exposed surface material (e.g., bright rays from craters such as Tycho) darken with time due mainly to the production of glass during micro- meteorite impacts. Since some magnetic anomalies correlate with unusually bright regions, the solar wind bombardment (which is strongly deflected by the magnetic anomalies) may also be responsible for darkening the surface [I]. -

DESIGN OF AUTONOMOUS COUPLING MECHANISM FOR MODULAR RECONFIGURABLE LUNAR ROVERS by CHRIS LYKE Bachelor of Arts Honors Thesis Thayer School of Engineering Dartmouth College Hanover, New Hampshire Date: __________________________ Approved:______________________ Advisor’s Signature ______________________________ Author’s Signature Abstract Modular reconfigurable robotics consist of modules that can join together to form larger entities capable of changing their morphologies for improved versatility, robustness, and cost. Coupling mechanisms play a key role in these systems, as they are the component connecting the modules and enabling the robot to change shape. Coupling mechanisms also define the structure, rigidity, and function of modular systems. This paper details the development of the autonomous coupling mechanism for SHREWs, a modular reconfigurable system of rovers designed to explore the permanently shadowed regions of the Moon. -
Mr. James Desantis, Astronaut Memorial Foundation
To: Mr. James DeSantis, Astronaut Memorial Foundation NASA Kennedy Space Center November 11, 1996 "Veterans Day" is a good moment to reflect on people who have died in the service of the United States, and in particular, on people who have died in the service of the manned space activities of this country. We are still trying to establish in your mind that Major Robert Lawrence was one such person. Regarding your correspondence with Mr. Roger Blanchard of the AF Personnel Center, I want to make sure you have the "big picture" regarding whether or not he should be formally recognized as a "dead American astronaut" on the "Astronaut Memorial Foundation". A recent exchange of letters between you and the AF indicates to me that, while you are being technically accurate, you both are still missing the point. Whether or not Major Lawrence ever earned (or deserved) "Air Force Astronaut Status" is irrelevant, since that is not what is necessary to gain recognition by the AMF, as you realize. Neither USAF Major Charles Bassett, nor USAF Captain Theodore Freeman, ever earned that status, yet they are both on the memorial BECAUSE THEY WERE KILLED IN TRAINING FOR THE ASTRONAUT PROGRAM. So they were undeniably "real astronauts" even if they did not have formal USAF "astronaut status". Unless it is your position that both Bassett and Freeman are on the memorial erroneously and should be removed (and of course you don't advocate that, nor do I), you must accept that Major Lawrence's case is a precise analog of theirs. -
