The National Aeronautics and Space Administration (NASA) is the agency of the United States Federal Government responsible for the civilian space program as well as aeronautics and aerospace research.

President Dwight D. Eisenhower established the National Aeronautics and Space Administration (NASA) in 1958 with a distinctly civilian (rather than military) orientation encouraging peaceful applications in space science. The National Aeronautics and Space Act was passed on July 29, 1958, disestablishing NASA's predecessor, the National Advisory Committee for Aeronautics (NACA). The new agency became operational on October 1, 1958.

Since that time, most US space exploration efforts have been led by NASA, including the Apollo moon-landing missions, the Skylab space station, and later the Space Shuttle. Currently, NASA is supporting the International Space Station and is overseeing the development of the Orion Multi-Purpose Crew Vehicle, the Space Launch System and Commercial Crew vehicles. The agency is also responsible for the Launch Services Program (LSP) which provides oversight of launch operations and countdown management for unmanned NASA launches.

Space Shuttle

The Space Shuttle was a partially reusable low Earth orbital spacecraft system operated by the U.S. National Aeronautics and Space Administration (NASA), as part of the Space Shuttle program. Its official program name was Space Transportation System (STS), taken from a 1969 plan for a system of reusable spacecraft of which it was the only item funded for development. The first of four orbital test flights occurred in 1981, leading to operational flights beginning in 1982. They were used on a total of 135 missions from 1981 to 2011, launched from the Kennedy Space Center (KSC) in Florida. Operational missions launched numerous satellites, interplanetary probes, and the Hubble Space Telescope (HST); conducted science experiments in orbit; and participated in construction and servicing of the International Space Station. The Shuttle fleet's total mission time was 1322 days, 19 hours, 21 minutes and 23 seconds.

Shuttle components included the Orbiter Vehicle (OV), a pair of recoverable solid rocket boosters (SRBs), and the expendable external tank (ET) containing liquid hydrogen and liquid oxygen. The Shuttle was launched vertically, like a conventional rocket, with the two SRBs operating in parallel with the OV's three main engines, which were fueled from the ET. The SRBs were jettisoned before the vehicle reached orbit, and the ET was jettisoned just before orbit insertion, which used the orbiter's two Orbital Maneuvering System (OMS) engines. At the conclusion of the mission, the orbiter fired its OMS to de-orbit and re-enter the atmosphere. The orbiter then glided as a spaceplane to a runway landing, usually at the Shuttle Landing Facility of KSC or Rogers Dry Lake in Edwards Air Force Base, California. After landing at Edwards, the orbiter was flown back to the KSC on the Shuttle Carrier Aircraft, a specially modified Boeing 747.

Discovery Channel

Discovery Channel (formerly The Discovery Channel from 1985 to 1995, and often referred to as simply "Discovery") is an American basic cable and satellite television channel (which is also delivered via IPTV, terrestrial television and internet television in other parts of the world) that is the flagship television property of Discovery Communications, a publicly traded company run by CEO David Zaslav. As of June 2012, Discovery Channel is the third most widely distributed cable channel in the United States, behind TBS and The Weather Channel; it is available in 409 million households worldwide, through its U.S. flagship channel and its various owned or licensed television channels internationally.

It initially provided documentary television programming focused primarily on popular science, technology, and history, but in recent years has expanded into reality television and pseudo-scientific entertainment. Programming on the flagship Discovery Channel in the U.S. is primarily focused on reality television series, such as speculative investigation (with shows such as MythBusters, Unsolved History, and Best Evidence), automobiles, and occupations (such as Dirty Jobs and Deadliest Catch); it also features documentaries specifically aimed at families and younger audiences.

Space

Space is the boundless three-dimensional extent in which objects and events have relative position and direction. Physical space is often conceived in three linear dimensions, although modern physicists usually consider it, with time, to be part of a boundless four-dimensional continuum known as spacetime. The concept of space is considered to be of fundamental importance to an understanding of the physical universe. However, disagreement continues between philosophers over whether it is itself an entity, a relationship between entities, or part of a conceptual framework.

The Young Turks

The Young Turks (TYT) is an online American liberal/progressive political and social commentary program hosted by Cenk Uygur and Ana Kasparian; the show has an associated network of online shows and is owned by a company of the same name (The Young Turks LLC). TYT was founded in 2002 by Uygur as a talkshow on Sirius Satellite Radio.

The Young Turks claims to be "the world's largest online news show"; YouTube video views for the TYT Network stood at a total of 2 billion as of July 2014. The show offers internet-only video content via their YouTube channel, which in April 2012 averaged 750,000 views a day, and by November 2014 over 1,400,000 views a day. The Young Turks also have a network of other affiliated shows on separate YouTube channels, known collectively as the TYT Network.

From 2011 to 2013 a second show, called The Young Turks with Cenk Uygur aired on Current TV. After Current TV was acquired by Al Jazeera America, the TV show was discontinued.

History

The Young Turks as a show began when Cenk Uygur started a talk show similar to a public-access television cable-TV show he had done previously called The Young Turk. With the help of friend Ben Mankiewicz (with whom he had previously worked), his childhood friend Dave Koller, and Jill Pike, he began The Young Turks as a radio show in 2002 on Sirius Satellite Radio. The show's name derives from the English-language phrase "Young Turk", meaning a reformist or rebellious member of an institution, movement, or political party.
