Near-Earth Objects (NEOs), Asteroids, and Comets This up-to-date electronic book on CD-ROM presents a comprehensive library of authoritative federal government scientific documents and publications covering all aspects of the threat posed to Earth by Near-Earth Objects (NEOs), asteroids, and comets. It provides a complete reproduction of the important March 2007 NASA report on NEO Survey and Deflection, an Analysis of Alternatives, plus complete coverage of Potentially Hazardous Objects (PHOs), impact risk assessment, and ongoing projects to detect, track, catalogue, and characterize these objects. There is detailed information about major NASA spacecraft missions studying asteroids and comets: DAWN, NEAR, STARDUST, DEEP IMPACT, and others. Asteroids and comets are the two types of potentially hazardous objects (PHO). For objects in the inner solar system, astronomers can distinguish these bodies on the basis of their appearance. Moving objects that appear as a star-like point of light are known as asteroids. Moving objects that appear diffuse or those that have visible tails are known as comets. People have known about comets sinc... |

Tunguska - Impact in Siberia 1908, Comets, Asteroids, and Near-Earth Object Threats, NASA Programs to Survey and Study Asteroids and Comets (CD-ROM) This electronic book on CD-ROM presents a library of federal government documents and publications covering all aspects of the threat posed to Earth by Near-Earth Objects (NEOs), and the Tunguska event which devastated a portion of Siberia in 1908. The Tunguska Event: The biggest meteor in recorded history shot across the Tunguska River in Russia in 1908, and exploded like a nuclear bomb. The Tunguska meteor did not make an impact crater, but some of the effects of its explosion are similar to what could happen in a large meteorite impact. At seven in the morning on June 30, 1908, a blazing meteor streaked across the sky in central Russia. It sped northwest from Lake Baikal toward the trading post of Baikit in central Siberia, an area of dense forests, wide swamps, and meandering rivers. Before reaching Baikit, the meteor exploded in a gigantic column of fire near the Tunguska River (61 N, 101.5 E). The effects of the explosion were felt worldwide. Around the globe scientists wondered at the rapid changes in atmospheric pressure and unusual vibrations in the Earth. People within a th... |
