Question: Which space flight carrying the first American to orbit the Earth was launched by T.J. O'Malley? 

Context paragraphs:
Geocentric orbit: A geocentric orbit or Earth orbit involves any object orbiting Planet Earth, such as the Moon or artificial satellites.  In 1997 NASA estimated there were approximately 2,465 artificial satellite payloads orbiting the Earth and 6,216 pieces of space debris as tracked by the Goddard Space Flight Center.  Over 16,291 previously launched objects have decayed into the Earth's atmosphere.

Apollo 8: Apollo 8, the second human spaceflight mission in the United States Apollo space program, was launched on December 21, 1968, and became the first crewed spacecraft to leave Earth orbit, reach the Earth's Moon, orbit it and return safely to Earth.  The three-astronaut crew — Commander Frank Borman, Command Module Pilot James Lovell, and Lunar Module Pilot William Anders — became the first humans to: travel beyond low Earth orbit; escape Earth's gravity; see Earth as a whole planet; enter the gravity well of another celestial body (Earth's moon); orbit another celestial body (Earth's moon); directly see the far side of the Moon with their own eyes; witness an Earthrise; escape the gravity of another celestial body (Earth's moon); and re-enter the gravitational well of Earth.  The 1968 mission, the third flight of the Saturn V rocket and that rocket's first crewed launch, was also the first human spaceflight launch from the Kennedy Space Center, Florida, located adjacent to Cape Canaveral Air Force Station.

Spaceflight: Spaceflight (also written space flight) is ballistic flight into or through outer space.  Spaceflight can occur with spacecraft with or without humans on board.  Examples of human spaceflight include the U.S. Apollo Moon landing and Space Shuttle programs and the Russian Soyuz program, as well as the ongoing International Space Station.  Examples of unmanned spaceflight include space probes that leave Earth orbit, as well as satellites in orbit around Earth, such as communications satellites.  These operate either by telerobotic control or are fully autonomous.

T. J. O'Malley: Thomas Joseph O'Malley (October 15, 1915 – November 6, 2009), better known as T. J. O'Malley, was an Irish-American aerospace engineer who, as chief test conductor for the Convair division of General Dynamics, was responsible for pushing the button on February 20, 1962 launching the Mercury-Atlas 6 space flight carrying astronaut John Glenn, the first American in orbit.  Five years later, NASA asked North American Aviation to hire him as director of launch operations to help get the Apollo program back on track after the Apollo 1 command module fire on the launch pad killed three astronauts.  O'Malley continued to play a leadership role in the United States' space program through the first space shuttle launch in 1981.

First Orbit: First Orbit is a feature-length, experimental documentary film about Vostok 1, the first manned space flight around the Earth.  By matching the orbit of the International Space Station to that of Vostok 1 as closely as possible, in terms of ground track and time of day, documentary filmmaker Christopher Riley and European Space Agency astronaut Paolo Nespoli were able to film the view that Yuri Gagarin saw on his pioneering orbital space flight.  This new footage was cut together with the original Vostok 1 mission audio recordings sourced from the Russian State Archive of Scientific and

Soviet space program: The Soviet space program (Russian: Космическая программа СССР, "Kosmicheskaya programma SSSR") comprised the rocketry and space exploration programs conducted by the former Soviet Union (USSR) from the 1930s until its dissolution in 1991.  Over its sixty-year history, this primarily classified military program was responsible for a number of pioneering accomplishments in space flight, including the first intercontinental ballistic missile (R-7), first satellite (Sputnik 1), first animal in Earth orbit (the dog Laika on Sputnik 2), first human in space and Earth orbit (cosmonaut Yuri Gagarin on Vostok 1), first woman in space and Earth orbit (cosmonaut Valentina Tereshkova on Vostok 6), first spacewalk (cosmonaut Alexey Leonov on Voskhod 2), first Moon impact ("Luna 2"), first image of the far side of the moon ("Luna 3") and unmanned lunar soft landing ("Luna 9"), first space rover ("Lunokhod 1"), first sample of lunar soil automatically extracted and brought to Earth ("Luna 16"), and first space station (Salyut 1).  Further notable records included the first interplanetary probes: Venera 1 and Mars 1 to fly by Venus and Mars, respectively, Venera 3 and Mars 2 to impact the respective planet surface, and Venera 7 and Mars 3 to make soft landings on these planets.

List of space flight simulator games: This is a comprehensive index of commercial, indie and freeware space flight simulator games.  The list is categorized into four sections: space flight simulators, space flight simulators with an added element of combat, space combat simulators with an added element of trading, and unreleased space flight simulators.

Advanced Composition Explorer: Advanced Composition Explorer (ACE) is a NASA Explorers program Solar and space exploration mission to study matter comprising energetic particles from the solar wind, the interplanetary medium, and other sources.  Real-time data from ACE is used by the NOAA Space Weather Prediction Center to improve forecasts and warnings of solar storms.  The ACE robotic spacecraft was launched August 25, 1997, and entered a Lissajous orbit close to the L Lagrangian point (which lies between the Sun and the Earth at a distance of some 1.5 million km from the latter) on December 12, 1997.  The spacecraft is currently operating at that orbit.  Because ACE is in a non-Keplerian orbit, and has regular station-keeping maneuvers, the orbital parameters in the adjacent information box are only approximate.  The spacecraft is still in generally good condition in 2015, and is projected to have enough fuel to maintain its orbit until 2024.  NASA Goddard Space Flight Center managed the development and integration of the ACE spacecraft.

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.

John Glenn: John Herschel Glenn Jr. (July 18, 1921 – December 8, 2016) was a United States Marine Corps aviator, engineer, astronaut, and United States Senator from Ohio.  In 1962 he became the first American to orbit the Earth, circling it three times.
