Projects To Minimize The Threat
Several surveys have undertaken "Spaceguard" activities (an umbrella term), including Lincoln Near-Earth Asteroid Research (LINEAR), Spacewatch, Near-Earth Asteroid Tracking (NEAT), Lowell Observatory Near-Earth-Object Search (LONEOS), Catalina Sky Survey, Campo Imperatore Near-Earth Objects Survey (CINEOS), Japanese Spaceguard Association, and Asiago-DLR Asteroid Survey. In 1998, the United States Congress mandated the Spaceguard Survey – detection of 90% of near-earth asteroids over 1 km diameter (which threaten global devastation) by 2008. This could be extended by the George E. Brown, Jr. Near-Earth Object Survey Act, which calls for NASA to detect 90 percent of NEOs with diameters of 140 meters or greater by 2020.
As of 2011, 911 of the largest (>1 km diameter) near-Earth asteroids have been found, with an estimate of 70 yet to be found.
On April 25, 2012, the Ecuadorian Space Agency announced that due a technological change in the video camera of its first satellite it will be adding a 3rd mission, which is to help organizations and individuals around the world monitor for small, most dangerous near-earth objects directly from orbit in real time and help fine tune the catalog of orbital debris by injecting the live video signal of the satellite into the Internet, thus turning the NEE-01 Pegasus in the first online, real-time video orbital sentry.

Famous quotes containing the words projects, minimize and/or threat:
“But look what we have built ... low-income projects that become worse centers of delinquency, vandalism and general social hopelessness than the slums they were supposed to replace.... Cultural centers that are unable to support a good bookstore. Civic centers that are avoided by everyone but bums.... Promenades that go from no place to nowhere and have no promenaders. Expressways that eviscerate great cities. This is not the rebuilding of cities. This is the sacking of cities.”
—Jane Jacobs (b. 1916)
“We do not need to minimize the poverty of the ghetto or the suffering inflicted by whites on blacks in order to see that the increasingly dangerous and unpredictable conditions of middle- class life have given rise to similar strategies for survival. Indeed the attraction of black culture for disaffected whites suggests that black culture now speaks to a general condition.”
—Christopher Lasch (b. 1932)
“The sickness of our times for me has been just this damn thing that everything has been getting smaller and smaller and less and less important, that the romantic spirit has dried up, that there is no shame today.... We’re all getting so mean and small and petty and ridiculous, and we all live under the threat of extermination.”
—Norman Mailer (b. 1923)
