full_context: Document 1: Jay Greene: Jay H. Greene is a retired NASA engineer. Between 2000 and 2004, he served as Chief Engineer at Johnson Space Center, where his role consisted primarily of advising the Center Director. He worked as a FIDO flight controller during the Apollo Program and a flight director from 1982 to 1986, most notably as ascent flight director during the Challenger accident in 1986. Greene worked for four years as a manager on the International Space Station project and received several awards for his work including the NASA Distinguished Service Medal. After his retirement in 2004 he served as a part-time consultant on the Exploration Systems Architecture Study. NASA Associate Administrator Rex Geveden described him as "a famous technical curmudgeon in the Agency."
Document 2: Annie Easley: Annie J. Easley (April 23, 1933 – June 25, 2011) was an African-American computer scientist, mathematician, and rocket scientist. She worked for the Lewis Research Center (now Glenn Research Center) of the National Aeronautics and Space Administration (NASA) and its predecessor, the National Advisory Committee for Aeronautics (NACA). She was a leading member of the team which developed software for the Centaur rocket stage and one of the first African-Americans to work as a computer scientist at NASA.
Document 3: Joan Feynman: Joan Feynman (born March 31, 1927) is an American astrophysicist. She has made important contributions to the study of solar wind particles and fields; sun-Earth relations; and magnetospheric physics. In particular, Feynman is known for developing an understanding of the origin of auroras. She is also known for creating a model that predicts the number of high-energy particles likely to hit a spacecraft over its lifetime, and for uncovering a method for predicting sunspot cycles. Feynman is the younger sister of physicist Richard Feynman.
Document 4: Jet Propulsion Laboratory: The Jet Propulsion Laboratory (JPL) is a federally funded research and development center and NASA field center in La Cañada Flintridge, California and Pasadena, California, United States.
Document 5: Payload Operations and Integration Center: Also known as Huntsville Operations Support Center (HOSC) or Payload Operations Center, it is a National Aeronautics and Space Administration (NASA) facility that works in conjunction with the International Space Station and Space Shuttle Control Centers in Houston, Texas. The Payload Operations Center at the Marshall Space Flight Center in Huntsville, Alabama, is the headquarters for International Space Station science operations. This Control Center links Earth-bound researchers and developers from around the world with their experiments and astronauts aboard the International Space Station.
Document 6: Applied Physics Laboratory: The Johns Hopkins University Applied Physics Laboratory, commonly known as simply the Applied Physics Laboratory, or APL, located in Howard County, Maryland, near Laurel and Columbia, is a not-for-profit, university-affiliated research center (or UARC) employing 6,000 people. The Lab serves as a technical resource for the Department of Defense, NASA, and other government agencies. APL has developed numerous systems and technologies in the areas of air and missile defense, surface and undersea naval warfare, computer security, and space science and spacecraft construction. While APL provides research and engineering services to the government, it is not a traditional defense contractor, as it is a UARC and a division of Johns Hopkins University. APL is a scientific and engineering research and development division, rather than an academic division, of Johns Hopkins.
Document 7: Dorothy Vaughan: Dorothy Johnson Vaughan (September 20, 1910 – November 10, 2008) was an African American mathematician and human computer who worked for the National Advisory Committee for Aeronautics (NACA), and NASA, at Langley Research Center in Hampton, Virginia. In 1949, she became acting supervisor of the West Area Computers, the first African-American woman to supervise a group of staff at the center.
Document 8: NASA facilities: NASA facilities exist across the United States, but also across the world. NASA Headquarters in Washington, DC provides overall guidance and political leadership to the agency. There are 10 NASA field centers, which provide leadership for and execution of NASA's work. These field centers are: Ames (Research), Armstrong (Flight Research), Glenn (Research), Goddard (Space Flight), JPL (Space Flight), Johnson (Space), Kennedy (Space), Langley (Research), Marshall (Space Flight), Stennis (Space). All other facilities fall under the leadership of at least one of these field centers. Some facilities serve more than one application for historic or administrative reasons. NASA has used or supported various observatories and telescopes, and an example of this is the NASA Infrared Telescope Facility. In 2013 a NASA Office of the Inspector General's (OIG) Report recommended a Base Realignment and Closure Commission (BRAC) style organization to consolidate NASA's little used facilities. The OIG determined at least 33 of NASA's 155 facilities were underutilized.
Document 9: Santa Susana Field Laboratory: The Santa Susana Field Laboratory is a complex of industrial research and development facilities located on a 2,668 acre portion of the Southern California Simi Hills in Simi Valley, California. It was used mainly for the development and testing of liquid-propellant rocket engines for the United States space program from 1949 to 2006, nuclear reactors from 1953 to 1980 and the operation of a U.S. government-sponsored liquid metals research center from 1966 to 1998. The site is located approximately 7 mi northwest from the community of Canoga Park and approximately 30 mi northwest of Downtown Los Angeles. Sage Ranch Park is adjacent on part of the northern boundary and the community of Bell Canyon along the entire southern boundary.
Document 10: California Institute of Technology: The California Institute of Technology (abbreviated Caltech) is a private doctorate-granting university located in Pasadena, California, United States.
Document 11: Ad Astra Rocket Company: The Ad Astra Rocket Company is an American rocket propulsion company dedicated to the development of advanced plasma rocket propulsion technology. Located in Webster, Texas, three miles away from NASA's Johnson Space Center, the company was incorporated on January 14, 2005. The President and CEO of Ad Astra Rocket Company is retired astronaut, Dr. Franklin Chang Díaz. The company has been working on Chang Díaz's concept of the Variable Specific Impulse Magnetoplasma Rocket, known by its acronym VASIMR. The VASIMR is intended to achieve several advantages over current chemical rocket designs, including lunar cargo transport, in-space refueling, and ultra-high speeds for distant space missions.
Document 12: David Florida Laboratory: The David Florida Laboratory is the Canadian Space Agency's spacecraft assembly, integration and testing centre, in Shirleys Bay, just west of Ottawa. It is operated by the Canadian Space Agency and rented out to Canadian and foreign aerospace and telecommunications companies and organizations for qualifying space bound equipment such as communication or scientific satellites, or components made to be placed on satellites or installed in a space station. The laboratory was named to honour C. David Florida, a leading Canadian pioneer in space research.
