Planetary Defense Coordination Office
The Planetary Defense Coordination Office (PDCO) is a planetary defense organization established in January 2016 within NASA's Planetary Science Division of the Science Mission Directorate. Its mission is to look for and catalogue near-Earth objects such as comets and asteroids and potentially hazardous objects that could impact Earth and to help the U.S. government prepare for a potential impact event (and coordinate efforts to mitigate and deflect potential threats if one is detected). History In 2005, the U.S. Congress passed the NASA Authorization Act, which, in part, tasked NASA with finding and cataloguing at least 90% of all near-Earth objects that are 140 meters or larger by 2020. However, that goal was clearly not being met by NASA's Near Earth Object Observations Program, which a 2014 report by the NASA Office of Inspector General pointed out. In June 2015, NASA and National Nuclear Security Administration of the U.S. Department of Energy, which had been stu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NASA
The National Aeronautics and Space Administration (NASA ) is an independent agencies of the United States government, independent agency of the US federal government responsible for the civil List of government space agencies, space program, aeronautics research, and outer space, space research. NASA was National Aeronautics and Space Act, 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 program, Apollo Moon landing missions, the Skylab space station, and the Space Shuttle.

Latin
Latin (, or , ) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area (then known as Latium) around present-day Rome, but through the power of the Roman Republic it became the dominant language in the Italian region and subsequently throughout the Roman Empire. Even after the fall of Western Rome, Latin remained the common language of international communication, science, scholarship and academia in Europe until well into the 18th century, when other regional vernaculars (including its own descendants, the Romance languages) supplanted it in common academic and political usage, and it eventually became a dead language in the modern linguistic definition. Latin is a highly inflected language, with three distinct genders (masculine, feminine, and neuter), six or seven noun cases (nominative, accusative, genitive, dative, ablative, and vocative), five declensions, four verb conjug ...

Impact Event
An impact event is a collision between astronomical objects causing measurable effects. Impact events have physical consequences and have been found to regularly occur in planetary systems, though the most frequent involve asteroids, comets or meteoroids and have minimal effect. When large objects impact terrestrial planets such as the Earth, there can be significant physical and biospheric consequences, though atmospheres mitigate many surface impacts through atmospheric entry. Impact craters and structures are dominant landforms on many of the Solar System's solid objects and present the strongest empirical evidence for their frequency and scale. Impact events appear to have played a significant role in the evolution of the Solar System since its formation. Major impact events have significantly shaped Earth's history, and have been implicated in the formation of the Earth–Moon system. Impact events also appear to have played a significant role in the evolutionary hi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asteroid Impact Avoidance
Asteroid impact avoidance comprises the methods by which near-Earth objects (NEO) on a potential collision course with Earth could be diverted away, preventing destructive impact events. An impact by a sufficiently large asteroid or other NEOs would cause, depending on its impact location, massive tsunamis or multiple firestorms, and an impact winter caused by the sunlight-blocking effect of large quantities of pulverized rock dust and other debris placed into the stratosphere. A collision 66 million years ago between the Earth and an object approximately wide is thought to have produced the Chicxulub crater and triggered the Cretaceous–Paleogene extinction event that is understood by the scientific community to have caused the extinction of all non-avian dinosaurs. While the chances of a major collision are low in the near term, it is a near-certainty that one will happen eventually unless defensive measures are taken. Astronomical events—such as the Shoemaker-Levy 9 imp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Screenplay
''ScreenPlay'' is a television drama anthology series broadcast on BBC2 between 9 July 1986 and 27 October 1993. Background After single-play anthology series went off the air, the BBC introduced several showcases for made-for-television, feature length filmed dramas, including ''ScreenPlay''. Various writers and directors were utilized on the series. Writer Jimmy McGovern was hired by producer George Faber to pen a series five episode based upon the Merseyside needle exchange programme of the 1980s. The episode, directed by Gillies MacKinnon, was entitled ''Needle'' and featured Sean McKee, Emma Bird, and Pete Postlethwaite''.'' The last episode of the series was titled "Boswell and Johnson's Tour of the Western Islands" and featured Robbie Coltrane as English writer Samuel Johnson, who in the autumn of 1773, visits the Hebrides off the north-west coast of Scotland. That episode was directed by John Byrne and co-starred John Sessions and Celia Imrie. Some scenes wer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Don't Look Up (2021 Film)
''Don't Look Up'' is a 2021 American apocalyptic political satire black comedy film written, co-produced, and directed by Adam McKay from a story he co-wrote with David Sirota. It stars Leonardo DiCaprio, Jennifer Lawrence, Rob Morgan, Jonah Hill, Mark Rylance, Tyler Perry, Timothée Chalamet, Ron Perlman, Ariana Grande, Kid Cudi, Cate Blanchett, and Meryl Streep. The film tells the story of two astronomers attempting to warn humanity about an approaching comet that will destroy human civilization. The impact event is an allegory for climate change, and the film is a satire of government, political, celebrity, and media indifference to the climate crisis. Produced by McKay's Hyperobject Industries and Bluegrass Films, the film was announced in November 2019. Originally set for theatrical release by Paramount Pictures, the rights were acquired by Netflix several months later. Lawrence became the first member of the cast to join, with DiCaprio signing on after his di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Infrared Telescope
An infrared telescope is a telescope that uses infrared light to detect celestial bodies. Infrared light is one of several types of radiation present in the electromagnetic spectrum. All celestial objects with a temperature above absolute zero emit some form of electromagnetic radiation. In order to study the universe, scientists use several different types of telescopes to detect these different types of emitted radiation in the electromagnetic spectrum. Some of these are gamma ray, x-ray, ultra-violet, regular visible light (optical), as well as infrared telescopes. Leading discoveries There were several key developments that led to the invention of the infrared telescope: * In 1800, William Herschel discovered infrared radiation. * In 1878, Samuel Pierpoint Langley created the first bolometer. This was a very sensitive instrument that could electrically detect incredibly small changes in temperature in the infrared spectrum. * Thomas Edison used an alternative techno ...

Polar Orbit
A polar orbit is one in which a satellite passes above or nearly above both poles of the body being orbited (usually a planet such as the Earth, but possibly another body such as the Moon or Sun) on each revolution. It has an inclination of about 60 - 90 degrees to the body's equator. Launching satellites into polar orbit requires a larger launch vehicle to launch a given payload to a given altitude than for a near-equatorial orbit at the same altitude, because it cannot take advantage of the Earth's rotational velocity. Depending on the location of the launch site and the inclination of the polar orbit, the launch vehicle may lose up to 460 m/s of Delta-v, approximately 5% of the Delta-v required to attain Low Earth orbit. Usage Polar orbits are used for Earth-mapping, reconnaissance satellites, as well as for some weather satellites.Science Focus 2nd Edition 2, pg. 297 The Iridium satellite constellation uses a polar orbit to provide telecommunications services.
