    Do you really not see the difference between a spacecraft that is intended
    for permanent earth orbit and one that simply needs to be spun up to reach 
    escape velocity?  Of course it is true that while one of the deep-space
    probes is in orbit it could fail.  A booster can also fail on the ground
    endangering thousands, it is all a question of risk.  Putting hot space-
    craft in permanent (or not so permanent, if you ask the Canadians) orbit
    is a huge risk compared to the American policy of just using that kind
    of power in deep-space probes.
