Interview on Deflecting Incoming Planetoids
DEFLECTING INCOMING ASTEROIDS (Science Show: 12/11/2005)
There is a long tradition in film and literature of an asteroid being
diverted at the last moment from its collision course with Earth by the
miracles of space technology. Back in the real world, a study by Britian's
Engineering and Physical Sciences Research Council will look at some
realistic ways to avoid catastrophic collisions. Dr Ed Lew from the Johnson
Space Centre says that, with a couple of decades notice gravity could be
used to deflect an incoming asteroid.
