How are space probes to the outer planets such as Jupiter protected from being obliterated by collisions with asteroids in the asteroid belt?
A)   They aren't—we only lose one out of every four spacecraft to collisions with asteroids, so it is cheaper to take our chances.
B)   The spacecraft are equipped with cameras to detect asteroids so they can be directed safely around them.
C)   The spacecraft are sent in an inclined orbit that arcs above or below the asteroid belt, then crosses the ecliptic again near Jupiter.
D)   They aren't—asteroids are so far apart that the spacecraft just sail on through.
