l be discovered.  Unmanned asteroid probes are needed
before billions are spent on a manned mission, if only to find out for
sure what the things are made of.

   Why mess around with terraforming?

Why indeed?  I personally prefer space colonies.  It's interesting to
note that it *can* be done, if people want to pay for it.  As a
previous message stated there may be reasons for partially terraforming
Venus even if no one wants to live there.

To David Alpern (Alpern.Ibm-Sj@Rand-Relay):  The explosion of nuclear
devices in the ionosphere occured in the 1961-1963 in Projects Argus and
Starfish.  Exploded at alltitudes of 100 km, the explosions dumped
lots of charged particles into the ionosphere, which in some cases
caused the Earth's radiation belts to overload and collapse.
