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.

  • 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.

Further design improvements were made to Dover, Delaware in 1937 by Abram Nathanial Spanel. Mr. Spanel improve mobility for astronauts on Apollo 15 through 17 who was an inventor who became proficient at dipping latex material needed to sit in the lunar rovers and perform more advanced to form bathing caps and other commercial products. He became mobility exercises on the lunar surface. This suit was known as famous for ladies apparel made under the brand name of Playtex the model A7LB. A slightly modified ILC Apollo suit would also go that today is known worldwide. Throughout WWII, Spanel drove on to support the Skylab program and finally the American-Soyuz the development and manufacture of military rubberized products Test Program (ASTP) which concluded in 1975. During the entire to help our troops. In 1947, Spanel used the small group known time the Apollo suit was produced, manufacturing was performed as the Metals Division to develop military products including at both the ILC plant on Pear Street in Dover, Delaware, as well as several popular pressure helmets for the U.S. Air Force. the ILC facility in Frederica, Delaware.

  • THE EARLY APOLLO PROGRAM Project Apollo Was an American Space Project Which Landed People on the Moon and Brought Them Safely Back to Earth
    AIAA AEROSPACE M ICRO-LESSON Easily digestible Aerospace Principles revealed for K-12 Students and Educators. These lessons will be sent on a bi-weekly basis and allow grade-level focused learning. - AIAA STEM K-12 Committee. THE EARLY APOLLO PROGRAM Project Apollo was an American space project which landed people on the Moon and brought them safely back to Earth. Most people know about Apollo 1, in which three astronauts lost their lives in a fire during a countdown rehearsal, and about Apollo 8, which flew to the Moon, orbited around it, and returned to Earth. Just about everybody knows about Apollo 11, which first landed astronauts on the Moon. But what happened in between these missions? This lesson explores the lesser-known but still essential building blocks of the later missions’ success. Next Generation Science Standards (NGSS): ● Discipline: Engineering Design ● Crosscutting Concept: Systems and System Models ● Science & Engineering Practice: Constructing Explanations and Designing Solutions GRADES K-2 K-2-ETS1-1. Ask questions, make observations, and gather information about a situation people want to change to define a simple problem that can be solved through the development of a new or improved object or tool. NASA engineers knew that Apollo astronauts would need special training to succeed in their missions to the moon, but how could they train under conditions similar to those the crew would encounter? One answer was to send them to places with barren areas and volcanic features that were like what they expected to find on the lunar surface. The astronauts received geology training as well as practicing maneuvers in their spacesuits and driving a replica of the GRADES K-2 (CONTINUED) lunar rover vehicle.

  • Apollo 7–10 Records Everywhere, but to Make HQ Archives Records More Broadly Available
    Robyn K. Rodgers 8-15-2018 Apollo Finding Aid Apollo Mission Summary: “That's one small step for [a] man. One giant leap for mankind.” – Neil Armstrong The national effort that enabled Astronaut Neil Armstrong to speak those words as he stepped onto the lunar surface fulfilled an American goal set by President Kennedy. Project Apollo’s goals went beyond landing Americans on the moon and returning them safely to Earth. They included establishing the technology to meet other national interests in space; achieving preeminence in space for the United States; carrying out a program of scientific exploration of the Moon; and developing man’s capability to work in the lunar environment. Apollo Missions 7–10, the focus of this finding aid, played significant roles in accomplishing these tasks. Section 1: Administrative Summary There is no one vast “Apollo collection” at NASA. Bodies of records are located at NASA Headquarters (HQ) Archives, at the Centers involved in the Apollo program, and at the National Archives (NARA). Records available the HQ Archives include copies made before records were sent to NARA, records that were obtained as part of various authors’ research collections, press clippings, NASA-published materials, family donations, copies obtained from the internet, or materials found to have agency and/or public interest. In keeping with archival principles, they have been kept and described in the context in which they were received, not grouped together simply because they are related to an Apollo mission. This finding aid consists only of materials housed or supported by the HQ Archives. It does not encompass any of the Center materials, nor does it delve extensively into records in NARA’s possession.

  • The Space Race Documented Through Front Pages of Newspapers from Around North America
    The News Frontier The Space Race documented through front pages of newspapers from around North America Newspapers and patches generously donated to the McAuliffe-Shepard Discovery Center by Jerrid Kenney After the end of World War II, a new battle began: the Cold War. In the mid-20th century, the United States and the Soviet Union were each trying to prove they were better than the other. Both sides wanted to show the superiority of their technology, military, and, by extension, their political systems. Starting in the late 1950s, the battlefront reached space. The United States and the Soviet Union fought to first achieve milestones in space exploration—starting in 1957 with the Soviet Union’s launch of Sputnik I, continuing through the U.S.’s landing astronauts on the Moon in 1969, and ending with a handshake in space between American astronauts and Soviet cosmonauts in 1975. Witness the fight for extraterrestrial might by reading about the United States and the Soviet Union’s major feats of the Space Race, as recorded in American and Canadian newspapers in real time.
