I think it's safe to say that nobody would want kilogram quantities of
anti-matter concentrated in any one place on the planet.  Such a thing
could ruin th eneighborhood and bring property prices screaming down
around our ears.

Actually, I wonder if even the moon would be a safe place to
concentrate a few hundred kilograms of the stuff.  Maybe the
farside...  I think I would prefer Mars.

Lets see.  100kg, e=mc^2, thats 9e25 ergs right.  The Sun puts out
4e33 ergs in a sec and has a surface area of about 6e12 km^2.  So, an
accident with 100kg of antimatter would be sort of like having a piece
of the sun, roughly the size of Texas, in your back yard for about 1
second.  Not particularily desirable.

Well if you _must_ use some planetary body, the far side of the moon
is just fine. 100kg of anti-matter will only yield a 4 gigaton
explosion (assuming it's reactive enough to all go boom at once).
Sure, you'll leave a pretty big crater, but it's not going to shift
the moon or anything.

The point is this: ex-Soviet (Russian/Ukranian) technology most likely
will be used in some rather substantial capacity and some combination
of the above countries will become ESA members whether they are geographically
located in Europe or not.

It makes sense economically, politically and any other way there is to
measure things.

They (i.e. the governments involved) probably can't find any agreement even
for purchasing empty space.

which is another reason that they will not do it. Since in Germany the public
has changed its mind on space projects, and the government spends all money
for things correlated with reunification, ESA has a huge lack in funding.
So everything looks like NO future for ESA.

I think the real point here is that you completely ignored what I wrote and
simply poted what you would *like* to see.

In principle, it would be good for the former Soviet states to cooperate
with the ESA and contribute their storehouse of experience and knowhow.

In practice, it's extremely unlikely.  Funding for the ESA comes from contri-
butions by the member nations, and there is no way the ex-Soviet states can
afford it.  The only way they could even consider it is if they completely
scrapped their current space program and subordinate themselves to the ESA,
which is unlikely, to say the least.

I think what we are going to see happen is a fairly signifigant scaleback in
Russian space activity for several years, followed by a gradual resumption to
former levels around the turn of the century, when their economy starts to
function again.  As for the ESA, God only knows what is going to happen to
them...probably bicker themselves to death.

Should look up terms like "in kind" aid. And "cheaper facilities." And
"hypersonic wind tunnels."  And other goodies which could be rented at cost.

If DoE can spend $9 million to fund fusion research in Russian and NASA is
preparing to spend more money with the not-so-evil Confederation, ESA
might do the same.

I think the first REAL commercialization of space (the sort of thing which Nick
and Alan espouse, but can't seem to get going here) is happening in Russia.
They've got incentive; if they don't get outside cash, they're unemployed.
With various export technology controls being lifted, it is quite feasible to
see some U.S. companies put together experiments here and send them up for
30-60-90-120 day stints on Mir. For cold cash.

Perhaps I've missed some crucial posts (which is entrirely possible given
a quirky news server) but I haven't seen a lot of news regarding the
details of the Galileo Antenna.

What is the confidence (of the NASA team, not some net-philosophers)
that thermal cycling will help?

What else can be attempted?  Thruster bursts? Fast rotation?

What is the confidence that *some* technique will succeed?

What is the schedule for more dramatic attmempts at freeing the antenna?

Any tidbits would be read. Thanks.

Maybe its not as bad as your gut reaction would lead you to believe.  By
definition this system would be oriented to areas where there are few
people.  Pranksters are unlikely to journey to a wilderness area just to
get their jollies.  Calls identified as coming from relatively populated
areas could be dispatched to local authorities, who would deal with
false alarms in the usual way.  When you pickup a signal from the North
Slope, you can be pretty sure it's genuine.  If it's 50 miles from
Anchorage, you leave it to the local people who know if it's near a road
or not and can act accordingly.  It's not like a malicious distress
call: the search area will be small and easy to locate.  Come to think
of it, we've had radios for long enough that rescue operations will be
used to a certain amount of background noise from cranks.

-To Anyone on this list who would enjoy answering my question about outer
-space:
-   The year is 2010. This is your last day on earth. Tomorrow you leave with

-the first civilian crew hand-picked by NASA to colonize the moon. NASA
-prepares your OFK - Offical Flight Kit - with all you need to survive
-physically on the moon. You are also allowed to take your PPK - Personal
-Preference Kit. It is the size of a traveler's shaving kit and must weigh no
-more than a pound. In it you must pack whatever you need to sustain you
-emotionally and spiritually in outer space.
-   What will you choose??

Well, you wouldn't need anything that could be produced on the moon, and
you wouldn't need photos, other images, literature, etc., because they can
be transmitted from Earth later on. So what you would want to concentrate on
are things that you value in themselves.

Some possibilities you might consider:
 - Legal documents (i.e. marriage licence), autographs, baseball cards, etc.
 - Food items that won't be available on the moon for many decades
    (though ruling out the possibility of ever being able to get things by
    "mail order" even at sky-high prices seems a little farfetched).
 - The shrunken head of a revered ancestor. (Bones, in the traditional Chinese
   custom, would be a little too heavy and bulky, unless further reduced.)
 - The Hope Diamond.

I wouldn't necessarily choose any of these, but others might.
What do people typically carry in their "luggage allowance" on the Concorde?

clearly you want to make sure that the singularity is massive enough
such that its evaporation rate is slower than its accretion rate.
Does anybody know what the relationships of mass to evaporation rate
is?  I was under the impression that explosive evaporation only took
place when the singularity was very very small, i.e. < 1e6g or so.

>- you still need lots of reaction mass.

You need reaction mass, yes.  The amound depends on the delta V you
need.  For short hops, you only need a little.  For long hauls, you
need more.  And, if you are thinking about interstellar hops, you can
still use the bussard ramscoop to collect hydrogen and blow it past
the singularity.

Can anybody tell us the efficiency of this with respect to a fusion
drive?

Maybe.  Remember you can control the charge of a singularity just by
forcing it to swallow some ions.  Also, its mass will give it a
certain amount of inertial stability, i.e. it's not likely to be
bouncing around its container at a decent fraction of C.  Thus, the
control system will have time to marshal it forces and keep the
singularity at bey.

I can guarantee that the answer to that question is "no". I mean, it

No need.  I'll stand up and ask it.  It is such a ridiculous question?
Would you want something from a nearby star system to come here and
accidentally reterraform Earth to their liking because they didn't notice
we were here?  Until we meet a new life form or two from another planet
I don't think you can make a convincing case for our ability to know

Very true that Lunar research suffered in the past, which should be improved.
So I'd like the LRM to be supported, it's important for planetary science.

On the other hand, that our knowledge on the Moon needs improvement, and,
therefore, LRM, should in *NO* way mislead anybody to think that we know
*ALL* interesting things (or even too much) on Mars and/or Venus. So also a
successor of Magellan, as well as Mars Observer (and LRM) should be taken
into consideration.

Also you should keep in mind that on longer terms there will either be manned
AND unmanned spaceflight or nothing but some commercial (and perhaps
military) sat's. In the non-scientific public (or, partially, even the
non-space scientific), people are PRO or CONTRA spaceflight as a whole,
as far as funded by public (assumed from observations here in Germany).
The anti-space party likes to profit from a manned-unmanned discussion:
as public funds decrease, both manned and unmanned space projects suffer,
which we just see concerning the ESA projects. So I urge everybody to
support *first* an increasing of space budget *as a whole*.

Good point. One practical use of such a requirement, however, might
be to provide a guideline for deciding when an active astronaut
should retire. A number of the astronauts wear glasses on-orbit;
likely many of them due to deteriorating eye-sight as they grow
older. Even if all new-hires had 20-20 uncorrected vision, once they're
in their 40's it'd start getting worse. The requirement may apply
less to new-hires than to old hands.

   A side remark on sci.space, as the discussion swept over from sci.misc:
   (Prof. Carl Sagan said similar things in COSMOS)

   I assume that many of the readers here are deeply interested in SETI,
   extra-terrestrial life (in particular, intelligent), etc.. How can one hope
   that there may be *any* useful (and peaceful) contact with ETI's if we
   are not even able to peaceful co-existence with the other TI's (the whales) ?

You presume: whales are intelligent and that useful => peaceful

   Please, no flames here. The discussion should stay on sci.misc.
           ^^^^^^^^^^^
What, no snide "cannibal" comments? At least try putting in your own
follow-ups if you want redirected discussion...
