Subject: Another Orbit Question
Newsgroups: sci.space
In light of the fact that a geostationary orbit above only one pole is
not possible, I have another question that concerns an idea that I have been
working on for the past few months. Is it possible to keep a body at
relatively the same point say about 20000 or so miles above the north pole
or south pole of the earth? I assume that it would require some type of
thrusting to keep it from orbiting around the earth in normal fashion. If
you could give some insight on this question such as the relative amount of
thrust this would require and whether it would have to be continuous or not
I would appreciate it.

Only if you thrust continuously to counter Earth's gravity. With normal
rockets, this will quickly exhaust your fuel supply. There has been some
thought about the possibility of using a solar sail for this, although it
would require much higher altitudes because the light-pressure thrust is
so feeble.

I was browsing through the ames.arc.nasa.gov archives the other day
looking for some GIFs. My problem isn't that the directory isn't 30k long
but I don't know what the images ARE. I tried FTPing the README and INDEX
files and that didn't help. One was the IMDISP dectription which I already
have and the other was something else.
How can I find out what any particular file is and ANY archive?
I'm also looking for a good orbital program to display orbits with the

BEST one to use???

Read the CONTENTS file. This file has descriptions of each of the GIFs.
Also, most of the GIF files have caption files (the *.txt files).

Subject: Detonavion vs Deflagration (was Re: Shuttle replacement)
Newsgroups: sci.space
I don't know if this is correct, but an article that came out in a local
paper on 29 January 1986 that said that the Challenger ET exploded with a
force of 1.7-2 megatons. If this is true then a launch pad accident
would destroy every out to about 10 miles from the pad.
One flaw: the large pieces of debris from the orbiter. A nuclear-equivalent
blast would have vaporized the orbiter. WMy point: a major source for concern
is the prospect of the media harping about Challenger when the DC-series
starts flying.

Subject: Just the fax?
To nobody's great astonishment, the Shuttle onboard facsimile receiver
has broken once again. (Actually, I can't remember a flight when the
fax worked all the way through.) There was some mention that the rollers
were not feeding the paper properly.
Fortunately, there's a backup device called the teleprinter. I would have
to guess that the fax machine is better than the teleprinter when it's
working, and that's why they bother to bring it along.

You may get better science return by flying up 7 tons of polar orbiter

Ok, then I will there be any way of obtaining VICAR?? I guess that it
would be hands off to ordinary people like myself.
Also, there is a program for the IBM PC called Vista Pro. To be as short
as possible in explaining this, it is a 3D landscaping gernerator that
accepts the U.S. Geological Survey's Digital Elivation Model images. You
can also creat liniar flybys with it. Can I do this with the Magellan
images or any other that are available? And if so, what other images are
available??? And, where can I get them?

Geo sync orbits only exist at 0 latitude. you could put a relay
at 90 degrees, but youd need a huge amount of fuel to hover there.
To do ppolar communications, either LEO relays sats are used
or you can create highly inclined highly elliptical orbits that
leave the bird hovering for a few hours at perigee, a modest tracking
antenna can then follow the bird. if you have several in the constellation, you can have continous coverage.

Hey Allen you might want to call range safety out at White sands to confirm
this. I cannot imagine that the first flight of a totally unproven system
that is unmanned would fly without range safety, ESPECIALLY at White Sands.
I bet the folks over in El Paso and Las Cruces would be a mite concerned as
well. I may be out at White Sands for the CONSORT 6 launch in late February or
early March and I can bet you that if we are anywhere near DC-X there will
be range safety to kill it to keep it away from us in case of trouble.

Anyone who listens to Rush Limbaugh should know by now that the truth is

Out of curiosity and perhaps a more reasonable comparision, could someone
post where and how KSC gets it's LOX and LH2?
What quantities are consumed?
Does most of the output go to the Shuttle?
Does anyone know what percentage of the US LH2 production is used by
NASA (i.e. is there some other major use for LH2)?
The current consumption of LOX/LH2 for space use seems to be a large
amount at irregular and infrequent intervals compared to the hoped for
routine use of SSTO.

A refueled ET in LEO with a Shuttle can't go anywhere since the engines

Well, I'm guilty of this as well, but hindsight is 20/20! Alas,
KH-11s, Space Shuttles, and GOES are a little on the expensive
side to build a whole bunch of backups. (Who'd have thought in
1985 that inside a year, all our space boosters would go kablooey?)

I sure it will, too, but I'm getting tired of waiting. That beast
flew in June 1989, and since then has spent more time sitting on
the launch pad than any other launcher in the world. This is the
marvelous machine that the military abandoned the Shuttle for. So
far, I'd say, they haven't gotten their money's worth. It's more
expensive than planned, harder to launch than planned, and is flying
much less frequently than planned. Sound familiar? That's why they
abandoned the Shuttle.

Three X-15s were built, and upgraded periodically throughout the
program. One crashed in 1968, just before the program was to end.
The other two are now at the Smithsonian and USAF Museum.

I don't quite remember what the code for the planet was...
There is a REAL good book called "The search for life in the Universe"
which had an interesting explantion for the Voyager plaque..
Unfortuantly I can't find it now and can't remember the author's name.

It was even clever, the _first_ time. We'll give him the benefit of

However, the claim that those tapes show some dog-fight in space is

Two things. First, much of the steam went out of the N-1 effort after
Apollo 11; they would have made their mistakes faster had the pressure
still been on. They knew they couldn't land before the US, *if* the US
stayed on schedule; they were hoping that the US would have trouble.
Second, the N-1 wasn't necessary for a circumlunar mission. Proton was
adequate to do that. They flew unmanned precursor tests: the Zond lunar
flights were stripped-down unmanned Soyuzes. If a man had been aboard
the last one of those, he'd have survived in comfort. (On the previous
one, he'd have had a rough flight but not a fatal one.) There was time
to launch another before Apollo 8. Nobody knows why it wasn't done;
the best guess is that they were trying but ran into minor problems of
some kind and missed the window.

Is there any way to actually get a look at Galileo as it whips by Earth?
Maybe if a few hi-res pictures of it can be taken, we could actually SEE what
is wrong with its antenna.
Just wondering,

It's just recently come out on CD, although it's expensive ($80 or so).
>I've always been interested in exactly what was recorded on it.
In that case, you probably want the book "Murmurs of Earth" rather than
the CD.
