Challenger (TV Film)
''Challenger'' is a 1990 American disaster drama television film based on the events surrounding the Space Shuttle ''Challenger'' disaster in 1986. Its production was somewhat controversial as the families of the astronauts generally objected to it. A prologue states that the film was "researched with the consultation of the National Aeronauts and Space Administration" and partly filmed at NASA's Johnson Space Center in Houston, Texas. Plot The film concentrates on the safety inspections and arguments surrounding the O-rings that ultimately were blamed for the explosion of ''Challenger''. While doing this, it also aims to show the personal humanity of the seven crew members. Generally, the film supports the Space Shuttle program and the dedication of NASA personnel in general while criticizing NASA management. After beginning on the eve of the launch, the rest of the film is told through flashback, beginning on July 19, 1985, when Christa McAuliffe was officially selected ...

Disaster Film
A disaster film or disaster movie is a film genre that has an impending or ongoing disaster as its subject and primary plot device. Such disasters may include natural disasters, accidents, military/terrorist attacks or global catastrophes such as a pandemic. A subgenre of action films, these films usually feature some degree of build-up, the disaster itself, and sometimes the aftermath, usually from the point of view of specific individual characters or their families or portraying the survival tactics of different people. These films often feature large casts of actors and multiple plot lines, focusing on the characters' attempts to avert, escape or cope with the disaster and its aftermath. The genre came to particular prominence during the 1970s with the release of high-profile films such as ''Airport'' (1970), followed in quick succession by '' The Poseidon Adventure'' (1972), ''Earthquake'' (1974) and ''The Towering Inferno'' (1974). The casts are generally made up of familia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Timeline Of STS-51-L
The STS-51-L mission started with the ignition of ''Challenger's'' main engines until the remote destruction of the two Solid rocket boosters (SRBs), and includes a transcript of crew conversations from the cockpit voice recorder on board the orbiter. STS-51-L was the twenty-fifth flight in the American Space Shuttle program, and marked the first time a civilian had flown aboard the Space Shuttle. The mission used Space Shuttle ''Challenger'', which lifted off from launch pad 39B (LC-39B) on January 28, 1986, from Kennedy Space Center, Florida. The mission ended in disaster following the destruction of ''Challenger'' 73 seconds after lift-off, because of the failure of an O-ring seals on ''Challenger''s right solid rocket booster, which led to the rapid disintegration of the Space Shuttle stack from overwhelming aerodynamic pressures. The seven-member crew was killed when the crew compartment hit the Atlantic Ocean at , after two and a half minutes of freefall. Summary timeline ...

O-ring
An O-ring, also known as a packing or a toric joint, is a mechanical gasket in the shape of a torus; it is a loop of elastomer with a round cross-section, designed to be seated in a groove and compressed during assembly between two or more parts, forming a seal at the interface. The O-ring may be used in static applications or in dynamic applications where there is relative motion between the parts and the O-ring. Dynamic examples include rotating pump shafts and hydraulic cylinder pistons. Static applications of O-rings may include fluid or gas sealing applications in which: (1) the O-ring is compressed resulting in zero clearance, (2) the O-ring material is vulcanized solid such that it is impermeable to the fluid or gas, and (3) the O-ring material is resistant to degradation by the fluid or gas. The wide range of potential liquids and gases that need to be sealed has necessitated the development of a wide range of materials. O-rings are one of the most common seals used i ...

Johnson Space Center
The Lyndon B. Johnson Space Center (JSC) is NASA's center for human spaceflight (originally named the Manned Spacecraft Center), where human spaceflight training, research, and flight control are conducted. It was renamed in honor of the late US president and Texas native, Lyndon B. Johnson, by an act of the United States Senate on February 19, 1973. It consists of a complex of 100 buildings constructed on in the Clear Lake Area of Houston, which acquired the official nickname "Space City" in 1967. The center is home to NASA's astronaut corps, and is responsible for training astronauts from both the US and its international partners. It houses the Christopher C. Kraft Jr. Mission Control Center, which has provided the flight control function for every NASA human spaceflight since Gemini 4 (including Apollo, Skylab, Apollo–Soyuz, and Space Shuttle). It is popularly known by its radio call signs "Mission Control" and "Houston". The original Manned Spacecraft Center grew out ...

NASA
The National Aeronautics and Space Administration (NASA ) is an independent agency of the US federal government responsible for the civil space program, aeronautics research, and space research. NASA was established in 1958, succeeding the National Advisory Committee for Aeronautics (NACA), to give the U.S. space development effort a distinctly civilian orientation, emphasizing peaceful applications in space science. NASA has since led most American space exploration, including Project Mercury, Project Gemini, the 1968-1972 Apollo Moon landing missions, the Skylab space station, and the Space Shuttle. NASA supports the International Space Station and oversees the development of the Orion spacecraft and the Space Launch System for the crewed lunar Artemis program, Commercial Crew spacecraft, and the planned Lunar Gateway space station. The agency is also responsible for the Launch Services Program, which provides oversight of launch operations and countdown management f ...

Prologue
A prologue or prolog (from Greek πρόλογος ''prólogos'', from πρό ''pró'', "before" and λόγος ''lógos'', "word") is an opening to a story that establishes the context and gives background details, often some earlier story that ties into the main one, and other miscellaneous information. The Ancient Greek ''prólogos'' included the modern meaning of ''prologue'', but was of wider significance, more like the meaning of preface. The importance, therefore, of the prologue in Greek drama was very great; it sometimes almost took the place of a romance, to which, or to an episode in which, the play itself succeeded. Latin On the Latin stage the prologue was often more elaborate than it was in Athens, and in the careful composition of the poems which Plautus prefixes to his plays we see what importance he gave to this portion of the entertainment; sometimes, as in the preface to the ''Rudens'', Plautus rises to the height of his genius in his adroit and romantic prolo ...

The spacecraft disintegrated above the Atlantic Ocean, off the coast of Cape Canaveral, Florida, at 11:39a.m. Eastern Time Zone, EST (16:39 Coordinated Universal Time, UTC). It was the first fatal accident involving an List of space programs of the United States, American spacecraft in flight. The mission, designated STS-51-L, was the tenth flight for the Space Shuttle orbiter, orbiter and the twenty-fifth flight of the Space Shuttle fleet. The crew was scheduled to deploy a communications satellite and study Halley's Comet while they were in orbit, in addition to taking school teacher Christa McAuliffe into space. The latter resulted in a higher than usual media interest and coverage of the mission; the launch and subsequent disaster were seen live in many schools across the United States. The cause of the disaster was the failure of the two O-ring seals in a joint in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Television Film
A television film, alternatively known as a television movie, made-for-TV film/movie or TV film/movie, is a feature-length film that is produced and originally distributed by or to a television network, in contrast to theatrical films made for initial showing in movie theaters, and direct-to-video films made for initial release on home video formats. In certain cases, such films may also be referred to and shown as a miniseries, which typically indicates a film that has been divided into multiple parts or a series that contains a predetermined, limited number of episodes. Origins and history Precursors of "television movies" include ''Talk Faster, Mister'', which aired on WABD (now WNYW) in New York City on December 18, 1944, and was produced by RKO Pictures, and the 1957 ''The Pied Piper of Hamelin'', based on the poem by Robert Browning, and starring Van Johnson, one of the first filmed "family musicals" made directly for television. That film was made in Technicolor, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drama Film
In film and television, drama is a category or genre of narrative fiction (or semi-fiction) intended to be more serious than humorous in tone. Drama of this kind is usually qualified with additional terms that specify its particular super-genre, macro-genre, or micro-genre, such as soap opera, police crime drama, political drama, legal drama, historical drama, domestic drama, teen drama, and comedy-drama (dramedy). These terms tend to indicate a particular setting or subject-matter, or else they qualify the otherwise serious tone of a drama with elements that encourage a broader range of moods. To these ends, a primary element in a drama is the occurrence of conflict—emotional, social, or otherwise—and its resolution in the course of the storyline. All forms of cinema or television that involve fictional stories are forms of drama in the broader sense if their storytelling is achieved by means of actors who represent ( mimesis) characters. In this broader sense, drama ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monaural
Monaural or monophonic sound reproduction (often shortened to mono) is sound intended to be heard as if it were emanating from one position. This contrasts with stereophonic sound or ''stereo'', which uses two separate audio channels to reproduce sound from two microphones on the right and left side, which is reproduced with two separate loudspeakers to give a sense of the direction of sound sources. In mono, only one loudspeaker is necessary, but, when played through multiple loudspeakers or headphones, identical signals are fed to each speaker, resulting in the perception of one-channel sound "imaging" in one sonic space between the speakers (provided that the speakers are set up in a proper symmetrical critical-listening placement). Monaural recordings, like stereo ones, typically use multiple microphones fed into multiple channels on a recording console, but each channel is " panned" to the center. In the final stage, the various center-panned signal paths are usually mixed d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
