A realistic hazard model was decided upon, and the scenario developed from that: an incoming object about 1 kilometer in diameter, in an orbit ranging from the outer rim of the Asteroid Belt to within that of Earth’s. .Three basic possibilities are considered in this book. The first is the deflection of the asteroid, using remote probes along with a number of possible technologies to change the asteroid’s course. Second is the attempt of a manned mission, in order to plant a propulsion system on the asteroid to push it into a different orbit. Third is the nuclear option, a last-ditch attempt to break up and then disperse the asteroid using nuclear weapons. (A rather impractical combination of these second and third options were us | | 出版日期 | Book 2014 | | 关键词 | ASTRA project; Asteroid dangers description; Asteroid impact risk; Asteroid watch; Astronomical impact h | | 版次 | 1 | | doi | https://doi.org/10.1007/978-1-4614-8749-4 | | isbn_softcover | 978-1-4614-8748-7 | | isbn_ebook | 978-1-4614-8749-4Series ISSN 1614-659X Series E-ISSN 2197-6651 | | issn_series | 1614-659X | | copyright | Springer Science+Business Media, LLC 2014 |
