(1) RISK OF COLLISIONS FOR SATELLITES

From Paolo Farinella <paolof@tycho.dm.unipi.it>

Hi Benny.

Just to point to CCNet readers that yesterday's (June 24, 1999)
"Nature" (vol. 399, p.743) has published a short scientific
correspondence by A. Rossi, G.B. Valsecchi and myself entitled "Risk
of collisions for constellation satellites".

There is also an interview with Alessandro Rossi on "Discovery News Brief"
(http://www.discovery.com/news/archive/archive-subgen.html), although
Alessandro disclaims the statement about "the chances of anyone being
hit by a falling satellite..."

Regards

Paolo Farinella

(2) CLAIRVOYANCE?

From Bob Kobres <bkobres@arches.uga.edu>

It's good to learn that Mr. Friedman has the clairvoyance to determine
that there is a zero probability of ANYTHING dire enough to get us off
track occurring in the next half century or so.  I suppose this is how
he knows that our technical abilities and opportunities to use expanded
knowledge can ONLY improve over this time period.

BTW: I have NEVER advocated building "super-weapons!"

The knowledge of nuclear-explosives is not going to disappear unless we
do - the genie is out of the bottle:
http://abob.libs.uga.edu/bobk/1908.html. What can change is our
attitude toward each other and the living world in general. I happen to
believe that an accelerated INTERNATIONAL program to develop our
abilities to operate in Space can most quickly build the trust,
cooperation, and knowledge needed for us to come to terms socially with
our VERY recently acquired capacity to manipulate huge amounts of
energy and information. http://abob.libs.uga.edu/bobk/nica.html
Mounting and probing PHOs as a matter of policy is simply a means of
ensuring that we know the composition of the object and its dynamical
properties. The act of routinely placing detectors on these objects
can only be a valuable learning process and will help to ensure that we do not lose
track of PHOs that have been identified. Expensive? Perhaps, but then
so are those toilet seats!

Hoping that we can avert fried-mankind--from whatever vector!
