Planetary Defence Activities Beyond NASA and ESA
Planetary Defence Activities Beyond NASA and ESA Brent W. Barbee 1. Introduction The collision of a significant asteroid or comet with Earth represents a singular natural disaster for a myriad of reasons, including: its extraterrestrial origin; the fact that it is perhaps the only natural disaster that is preventable in many cases, given sufficient preparation and warning; its scope, which ranges from damaging a city to an extinction-level event; and the duality of asteroids and comets themselves---they are grave potential threats, but are also tantalising scientific clues to our ancient past and resources with which we may one day build a prosperous spacefaring future. Accordingly, the problems of developing the means to interact with asteroids and comets for purposes of defence, scientific study, exploration, and resource utilisation have grown in importance over the past several decades. Since the 1980s, more and more asteroids and comets (especially the former) have been discovered, radically changing our picture of the solar system. At the beginning of the year 1980, approximately 9,000 asteroids were known to exist. By the beginning of 2001, that number had risen to approximately 125,000 thanks to the Earth-based telescopic survey efforts of the era, particularly the emergence of modern automated telescopic search systems, pioneered by the Massachusetts Institute of Technology’s (MIT’s) LINEAR system in the mid-to-late 1990s.1 Today, in late 2019, about 840,000 asteroids have been discovered,2 with more and more being found every week, month, and year. Of those, approximately 21,400 are categorised as near-Earth asteroids (NEAs), 2,000 of which are categorised as Potentially Hazardous Asteroids (PHAs)3 and 2,749 of which are categorised as potentially accessible.4 The hazards posed to us by asteroids affect people everywhere around the world. -

INTRODUCTION Outer Space has always fascinated man, beginning from the Biblical days of the building of the Tower of Babel to this very Century in which it is particularly important in his everyday life. So, man has been making attempt to explore, he has explored and he is still exploring this important domain. This will remain so even to the end the days of the last man on Earth. The early vision of space leaders, particularly the U.S and Soviet Union, was space for prestige and supremacy. That vision was not different from that of the people of Babel: “Come, let us build ourselves ... a tower whose top is in the heavens. Let us make a name for ourselves …” (Genesis 11 The beginning of Space exploration was characterized by “State- selfishness” and unfriendly-race. Soviet Union made several achievements first: • launched Sputnik I in October 1957 • Cosmonaut Yuri Gagarin of Soviet Union became the first human being in space on April 12, 1961 Soviet Union leadership claimed that its first capabilities were evidence of its overall superiority These first-in-all achievements contributed to significant increase in Soviet Union national prestige vi- a-viz the U.S Kennedy and his advisers felt the need a to beat Soviet Union, to re-establish U.S prestige and demonstrate its leadership. -
