Newsgroups: sci.space
Hi everyone,
I was wondering if anyone knew of any Australian space societies, companies,
organisations etc that I could write to ( e-mail(?) ) and/or join.
I am particularly interested in any that are around the Melbourne area.
Please e-mail me at one of the addresses below.
Thanx in advance.
Andrew Bennett.

Implicit in this argument is the notion that activities in space
subtract from efforts to solve problems on earth.
This is simply not true.
In the Washington Post (and I suspect other newspapers) was a
major story this morning: Hurricane hits Florida. 10 people might
have died.
If we had followed your approach over the past 40 years, the
headlines might have read: Surprise hurricane hits Florida!
Thousands die!
That's the way things used to be -- before weather satellites.
Western civilization has been one of the greatest engines for
solving of problems the human race has ever created. But it
didn't accomplish all this by turning inward. It did it by
turning outward and embracing the world and persuing discovery.

How do you figure? I'm defining an HLV as having a larger payload than a
shuttle or Titan IV. That would put the number of construction launches around
a dozen. By itself, this doesn't look like a big enough market to spur
development of a new vehicle, and there isn't another market in sight. Add to
this the fact that shuttle will be going to Freedom anyway because people need
to be there and you cut the number of HLV launches down further.
Supply might be a market, but the astronauts are going to have to drink a lot
of tang to make this a big enough market to support an HLV

I thought the Soyuz discussion hit some nice engineering points; I learned a
lot and it got me to think. (Maybe it *did* drag on too long.)

This is a novel suggestion... might at least make a good SF story. It
would be cruel and vicious of me to suggest hiring postal employees
(some of my best friends are postal employees).

But, Gerald, that's how we Buck Rogers fans spent the Seventies and
Eighties, often without benefit of any drugs at all!

Yup, but it is running out of propellent and is due to burn up in the
atmosphere of Venus this December.
>Besides Magellan,
>what other spacecraft (Russian?) may be still functional?
Here's a list of deep space spacecraft that are still operating.
Pioneer 6, 7 & 8 (solar orbit)
Pioneer Venus
Pioneer 10 & 11 (left the solar system)
Voyager 1 & 2 (left the solar system)
Hiten (lunar orbit)
Giotto (solar orbit)
Ulysses (on its way to pass "underneath" the Sun)
Galileo (coming back for a Earth gravity assist and then on to Jupiter)
Sakigake (solar orbit)
Suisei (solar orbit)
ICE (solar orbit)
Strangely enough, the Soviets don't have any spacecraft still operating.

Yes, but not for long.
In September, the orbit will have decayed enough so that PV will start clipping
the atmosphere. Depending on if the remaining fuel can be used effectively,
and if there is enough left, there is a chance that the mission can last into
December. The chances of success are gauged at 50%. In any case, the
PV orbiter will be dead and gone by the end of the year.
Actually, the entry will allow for some snazzy experiments to be done in situ.
The mass spec and other instruments that haven't been able to be used in
the higher orbits will now be used.
Overall, the mission was an amazing success especially if you consider that
the nominal mission was exceeded by some twelve years. People should
remember these kinds of successes when they are getting down on NASA for
making mistakes (I don't think I need to name any ;-)
