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. -

Apollo 11 Astronaut Neil Armstrong Broadcast from the Moon (July 21, 1969) Added to the National Registry: 2004 Essay by Cary O’Dell “One small step for…” Though no American has stepped onto the surface of the moon since 1972, the exiting of the Earth’s atmosphere today is almost commonplace. Once covered live over all TV and radio networks, increasingly US space launches have been relegated to a fleeting mention on the nightly news, if mentioned at all. But there was a time when leaving the planet got the full attention it deserved. Certainly it did in July of 1969 when an American man, Neil Armstrong, became the first human being to ever step foot on the moon’s surface. The pictures he took and the reports he sent back to Earth stopped the world in its tracks, especially his eloquent opening salvo which became as famous and as known to most citizens as any words ever spoken. The mid-1969 mission of NASA’s Apollo 11 mission became the defining moment of the US- USSR “Space Race” usually dated as the period between 1957 and 1975 when the world’s two superpowers were competing to top each other in technological advances and scientific knowledge (and bragging rights) related to, truly, the “final frontier.” There were three astronauts on the Apollo 11 spacecraft, the US’s fifth manned spaced mission, and the third lunar mission of the Apollo program. They were: Neil Armstrong, Edwin “Buzz” Aldrin, and Michael Collins. The trio was launched from Kennedy Space Center in Florida on July 16, 1969 at 1:32pm. -

Physical Characteristics
Physical Characteristics Encyclopedia—moon The study of the moon's surface increased with the invention of the telescope by Galileo in 1610 and culminated in 1969 when the first human actually set foot on the moon's surface. The physical characteristics and surface of the moon thus have been studied telescopically, photographically, and more recently by instruments carried by manned and unmanned spacecraft (see space exploration). The moon's diameter is about 2,160 mi (3,476 km) at the moon's equator, somewhat more than 1/4 the earth's diameter. The moon has about 1/81 the mass of the earth and is 3/5 as dense. On the moon's surface the force of gravitation is about 1/6 that on earth. It has been established that the moon completely lacks an atmosphere and, despite some tantalizing hints that there might be ice under the surface dust in shaded portions of Shackleton Crater (near the moon's south pole), there is no definite evidence of water. The surface temperature rises above 100°C (212°F) at lunar noon and sinks below -155°C (-247°F) at night. The gross surface features of the moon are visible to the unaided eye and were first studied telescopically in 1610 by Galileo. Surface Features The lunar surface is divided into the mountainous highlands and the large, roughly circular plains called maria (sing. mare; from Lat.,=sea) by early astronomers, who erroneously believed them to be bodies of water. The smooth floors of the maria, varying from flat to gently undulating, are covered by a thin layer of powdered rock that darkens them and accounts for the moon's low albedo (only 7% of the incident sunlight is reflected back, the rest being absorbed). -

Thus, calmly, Command Module Pilot JackSwigert gave the first intimation of serious trouble for Apollo 13--200,000miles from Earth. CAPSULECOMMUNICATOR--ThisisHouston;say again, please. SC--Houston, we've hada problem. We've hada MainBbusundervolt. By "undervolt"Swigert meant a drop in power in one of the Command/Service Module's two main electrical circuits. His report to the ground began the most grippingepisode in man's venture into space. One newspaper reporter called it the most public emergency and the most dramatic rescue in the history of exploration. SC--Andwe hada pretty large bang associatedwith the cautionandwarning here. Lunar Module Pilot Fred Haise was now on the voice channel from the spacecraft to the Mission Control Center at the National Aeronautics and Space Administration's Manned Spacecraft Center in Texas. Commander Jim Lovell would shortly be heard, then again Swigert--the backup crewman who had been thrust onto the first team only two days before launch when doctors feared that Tom Mattingly of the primary crew might come down with German measles.

Celebrate Apollo
National Aeronautics and Space Administration Celebrate Apollo Exploring The Moon, Discovering Earth “…We go into space because whatever mankind must undertake, free men must fully share. … I believe that this nation should commit itself to achieving the goal before this decade is out, of landing a man on the moon and returning him safely to Earth. No single space project in this period will be more exciting, or more impressive to mankind, or more important for the long-range exploration of space; and none will be so difficult or expensive to accomplish …” President John F. Kennedy May 25, 1961 Celebrate Apollo Exploring The Moon, Discovering Earth Less than five months into his new administration, on May 25, 1961, President John F. Kennedy, announced the dramatic and ambitious goal of sending an American safely to the moon before the end of the decade. Coming just three weeks after Mercury astronaut Alan Shepard became the first American in space, Kennedy’s bold challenge that historic spring day set the nation on a journey unparalleled in human history. Just eight years later, on July 20, 1969, Apollo 11 commander Neil Armstrong stepped out of the lunar module, taking “one small step” in the Sea of Tranquility, thus achieving “one giant leap for mankind,” and demonstrating to the world that the collective will of the nation was strong enough to overcome any obstacle. It was an achievement that would be repeated five other times between 1969 and 1972. By the time the Apollo 17 mission ended, 12 astronauts had explored the surface of the moon, and the collective contributions of hundreds of thousands of engineers, scientists, astronauts and employees of NASA served to inspire our nation and the world. -
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. -

Geology of the Moon
Geology of the moon William Joyce The moon is a little more accessible than other bodies in the solar system and this talk aimed to explain what moon rock reveals about the geology of the moon, which is an igneous cumulate complex. After some facts about the moon it looked at early ideas of the nature and origin of the moon, observations from earth, a look at both sides of the moon, major surface types – maria, highlands – craters and fieldwork near and on the moon. It finished with modern ideas on how the moon formed and some thoughts on impacting asteroids and volcanic eruptions. Facts The moon’s mass is 7.35x1022kg, 1.25% that of the earth. Its radius is 1,737km, 27.25% of the earth’s and its surface area 3.79x107km2, 7% of the earth’s. Its density is 60% of earth’s at 3.3g/cm3 and its gravity is 16.5% of earth’s at 1.62m/sec2. Its day is 27.322 earth days and temperatures range from +130oC to -130oC. As the only long-term natural companion of earth, the moon is a fairly large planetary body in its own right and has a complex geological history. 1t is 384,400km distant from earth, the equivalent of 60 earth radii. Early ideas Galileo Galilei was one of the first to make observations of the moon using a 20X telescope and published drawings of it in his Sidereii nunclus (1610). Thomas Harriot used a 6X telescope and produced the first drawings of the moon in 1609, before Galileo, and produced a map of the moon.
