Nonsense.  There is no reason why R&D work on more advanced systems could
not go on.  But it is important to distinguish building a reliable and
cost-effective launcher from doing R&D in advanced launcher technology.
The two are not the same; indeed, they are incompatible.  If we want
something that works well and that has some chance of being cheap, we
*want* technology that is old enough to have been debugged.

>(Also, much of the Saturn would have to be redesigned ...

Nonsense again.  Almost nothing would need redesign; the only area I
can think of where this would be beneficial would be the electronics.
We'd need to redesign the *tooling*, and that would cause small changes
in the design of the launcher, and much of it would have to be re-tested,
but the basic design is not broken and does not need fixing.

a country with reliable and cost-effective low-tech launchers is much more
of an aerospace leader than one which can't make its high-tech birds work.

POTENTIAL GEOMAGNETIC STORM WARNING CANCELLATION

The following Warning has been CANCELLED:

     - POTENTIAL GEOMAGNETIC STORM WARNING (cancelled).

Potential GIC Status: GREEN.


     The flare effects from the major X-class flare of 20 April failed to
materialize.  The window for potential geomagnetic storming has passed.  As a
result, the Potential Geomagnetic Storm Warning has been terminated.
Geomagnetic activity is expected to remain generally quiet to unsettled for
the next couple of days.

     Solar activity indices have been dropping rapidly over the last several
days.  In particular, the solar flux has dropped to a level of 146 on 23
April, which is the lowest level observed since 02 November, 1990.  Major
flaring is no longer possible from the few very weak regions currently
visible on the solar disk.  In fact, only minor C-class flaring and
occassional subflaring appears possible.  SIDs/SWFs are not expected over the
next several days.  Stable ionospheric conditions should prevail.

     HF and VHF propagation conditions will remain near normal over the next
several days.  No periods of degradation are anticipated.

     Auroral activity will remain generally dormant.

Subject: Eclipse Trip to Mazatlan
X-Vmsmail-To: SMTP%"[e-mail]"

   For those who would like an "out of this world" experience, there still
are a few spaces left on an eclipse trip to Mazatlan for which I am the
science advisor.  We leave July 9 from Houston (chartered nonstop flight),
stay 3 nights at the (beachfront) El Cid Mega Resort; watch the eclipse
from on the grounds of the hotel (5 minutes and 27 seconds of totality;
more if you want to share a cab and go somewhere else); and return July 12.
The cost is $599 each for double occupancy; $569 each, triple; $559, quad.
Hotel, air (from Houston) and transfers to and from airport are included;
meals and local travel are not.  (Who wants someone else to arrange their
meals in Mexico??)   This is the cheapest such trip I've seen advertised
anywhere, and the operator is working at virtually no profit (he upped the
class of the hotel without increasing the price).

   The tour operator is experienced in arranging amateur astronomy travel;
I went with them to Canada in '79 and was a guide to Australia for Halley's
Comet in '86. They have also arranged eclipse trips to many other places.

   For information call George at Hanssen/Future travel [phone].  In
Houston call [phone] or 480-1988.  Tell him I sent ya.

They need the cash too badly...they'd provide decent services. There's nothing
which NASA needs to lift into orbit on Energia which couldn't wait a couple of
years in case of disruption of launch services from the Soviet Union via
political events.

NASA projects lived through the disruption of services after Challenger, which
was UN-anticipated. With a little contingency planning, Energia could work.

There was a failure back in the mid-80's, but it was due to the fuel
tank. If the engine was the cause of the failure, it would be the
first one in a very long time. Which is why I suspect the electronics,
but then again I'm no expert.

If there is shooting in the area and the rebels control the launch pad then
they won't be able to provide decent service.

If they reopened the Gulag and Congress held up the launch on human rights
grounds then we wouldn't get good launch services.

Of course, the last disruption in the Soviet Union because of political events
lasted 70 years.

I agree that nothing NASA is doing couldn't wait a couple of years (subject
to launch windows). However, that is not what I am talking about. I would
like to see an active US space program which produces a spacefairing
civilization. To do this the Soviets are not reliable enough.

        I don't entirly agree with the Anti-trust thing, I mean if America
        can allow murders to run rabid, crazies to mass murder 10+ people
        and put them back on the street, allow police officers to beat up
        people for enjoyment.  I think congress can overlook a simple little
        thing like Anti-trust.  Besides with half of America on drugs I really
        don't think anyone is going to notice.  At least this is what is printed
        in the Japanese news, that an average Japanese will read.

Subject: FACE on MARS -- Request for info...

Hello there

 Recently I have heard numerous times that some Mars mission
actually found evidence of some form of skillful habitants. I am told
that there are

        1. pyramids like in Egypt but with the twist that the base
           is pentagonal.

        2. formations that resembles a face.

        3. the ruins of a town ....

I have been trying to get hold of an OMNI issue which covers this
material. So far not much luck. I have not read this weeks LIFE taboid
that talks about LIFE On MARS.

Thus I would appreciate any information you might have on this topic.
Thank you ...


Other:
        The notion that Earth is the only place where life exists is quite
a bit strange. There is no definitive proof to challenge this notion.
So we live without a resolution ... To the mind that beleives in LIFE
other than EARTHLING ...the mere probabilistic stmt. that
"There exists a finite non-zero probability that in ...." is not
enough.

The netter's knowledge may help me in this regard ....

 Thank you very much

That is an interesting idea.  If anyone knows any more about this, please say
something.  Is there any way to alter the VEEGA trajectory in such a way as
to bring it back to Earth at a low enough velocity to drop it into Earth orbit
for repair?  I realize it probably wouldn't get back until 1998 if it's even
possible, but we could then retrieve it, fix it, and re-launch.

I don't wish to flame anyone either; but you're wrong.

I know of Spitfires, Mustangs, Hellcats, Bearcats, Corsairs, Skyhawks, Migs
Tomcats, etc., etc., etc., as well as tons of civilian craft, but I ain't
never heard of R100 or R101 before you mentioned them.

Just because YOU know them as well does not mean they are as well known.
