To The Asteroids - and Beyond! - John Lewis (SETI Talks)
Μετάδοση με ζωντανή ροή στις 10 Σεπ 2013
SETI Talks archive: http://seti.org/talks
Speaker: John Lewis
Professor Emeritus of planetary science at the University of Arizona's Lunar and Planetary Laboratory
Abstract:
Tsiolkovsii
and Goddard dreamed of the day when we would have access to the
resources of the asteroids. Today, with an enormous and rapidly growing
body of data on meteorites, the Near-Earth Asteroids (NEAs) and their
more distant counterparts, we can envision the propulsion systems,
transportation system architectures, ores, processing schemes and
markets for products made from materials sourced in nearby space. Most
of these products are of greatest value and significance in space; some,
such as platinum-group metals and energy, would be worth returning to
Earth.
The resources of the NEAs also provide the propellants and
structural materials for a broad expansion of human presence in space.
This talk will survey the what, where, how and why of space resource utilization-- and raise the timely question of when.
