Mass production can be a wonderful cost reducer if the product is
needed in huge quanties, and if the product is mature. But when
the product is immature, too early a standardization can lock in
inefficient designs and stunt the development of better designs.
Despite the fact that we are 36 years into the space age, we've
flown fewer missions than were flown in one month in 1918 in
fighter aircraft. We don't have the demand for sufficient flights
to require mass production. And we don't have the experience to
decide which design should be standardized. Since the market is
so small, standardization now would end most competing design
work because there isn't sufficient demand to support more than
one mass production line.
The span from Wright Bros to DC-3 shouldn't be measured in
years. It should be measured in flight hours. When you look
at it that way, we haven't reached 1907 yet in spaceflight.
Would you have us standardize on 1907 aircraft?

Actually, on the basis that any landing you can walk, or swim, away
from being a good one, winged vehicles have a real edge over rocks,
err rockets. With all engines out, many aircraft can ditch successfully,
and most can touch down on any spot of fairly level ground. The *plane*
may sustain major damage, but as long as the contents survive, that's
relatively unimportant. Three of four loss of power incidents with
general aviation aircraft in Georgia in the last month have resulted
in no fatalities. The one exception was in a thunderstorm the pilot
should have avoided. In fact, engine out procedures are a required part
of pilot training. When flying VFR, a pilot should always have an
emergency landing site in mind within his gliding range.

Subject: Federal Research Program Info
Newsgroups: sci.space
I've come across this source of information that I think would be of
interest to subscribers of this newsgroup, and thought I would pass it
along. It is accessible through the Internet or by PC with a toll free number.
WHAT IS FEDIX?
FEDIX is an on-line information service that links the higher education
community and the federal government to facilitate research, education,
and services. The system provides accurate and timely federal agency
information to colleges, universities, and other research organizations.

All true, but it overlooks the primary objections. We don't do self-
replicating robotic manufacturing from dirt on Earth because (a) we
don't know how, (b) even if we did know how, it's not economic in
competition with other methods using higher grade raw materials. Now
given we don't do this on Earth, why would anyone think it workable
on the Moon? There may be some processes that are easier in low
gravity/vacuum, but why do we think robotic replication is one of
them?
The real test of any lunar/ET manufacturing scheme is, does it deliver
something we need to the place we need it for the lowest cost? And second,
does the value of the material exceed the cost? So far, the answers for
lunar materials are no and no.

I don't care about rapid response, I'm trying to get my payload up
at the lowest mission cost.

Except why should I suspect there will *be* a Saturn launch anytime
in the next 20 centuries? I'm not concerned about time critical
payloads, I'm talking about lowest *cost* in any reasonable timeframe
to the orbit *my* payload needs. Saturn has such a high bulk lift capacity
that it's very rarely needed. And when it is, it's not likely to be
going to the orbit I need.

With very special payload constraints to fit the multi-payload
shrouds, and with very special integration demands. All that
costs $$$ and time to design custom payloads to fit the special
launcher requirements. *And* of course that design work is worthless
if you decide to change launchers. You can't just chuck your payload
in the hold with the other general cargo.

ROROs don't have the mass and volume constraints of spacecraft.
Even with a cheap launcher it costs a lot to carry the extraneous
mass of pallet containers to orbit. And if your payload doesn't
fit a standard pallet because of mission requirements, then you're
well and truly screwed. And if your mission requires an orbit that
other payloads don't happen to be heading toward, too bad. The
nature of the mission sets the size, shape, and destination of
the payload, and there are limitless numbers of different missions.
It's a lot like mass transit versus the private auto. It may be
cheaper to haul a person X miles on mass transit, but if the
tracks don't connect your origin and destination, transit's
lower costs are irrelevant. All that's important is the *mission*
cost of getting your butt from point A to point B.

Not yet, officially. Current funding ends in October 1993, but the project
is optimistic that they'll be funded for another year for gravity operations.
The additional cost for that year is about $7.4M, compared to roughly $800M
the project has cost so far. I don't remember who it is that has to OK the
continuation (Congress?).

You're the second person to say this in response to my post. Being

Long ago, I once heard of a satellite releasing thousands or millions of
1 inch or so snippits of fine copper wire into low orbit. An experiment
to see if these would improve long distance radio communications (bounce
the radio waves off the copper needles). The orbit was chosen so the
copper wire needles would re-enter after a while. To avoid long term
danger from all that space junk hitting something. Don't know if the
re-entry of this stuff was visible....

Subject: Mission to Mars. Plan and Ideas!
Newsgroups: sci.space
Here is a short plan to get to Mars, and soem ideas, feel free to correct me,
or suggest better and easier ways and methods.. (as in cost, payload, and
availabiltiy)..
I wrote most of this down while at my Hard Ware Clerk job so
It is a bit rough.
Stage 1: To Orbit, basically trying to get the material and support material
to get to Mars, basically into oearth orbit..
a. Heavy G payloads, namely stuff that can stand the heavy Gs from a space
gun, or other device that can get cargo into space, and you don't have to worry
about it being crushed, and stuff that alot of is needed..
b. Heavy Lift: Basically stuff that is large, bulky, and needs to be lifted
in one piece.
c. Low G, Low Lift Stuff (humans, delicate equipment that can't be built in
space).
Stage 2: In Orbit.
Space station or atleast a place to get all the gear and equaipment together..
To change from earth vehicles to a to mars vehicle..
Stage 3: To Mars.
a. Slow Heavy Cargo (via soalr sail, or other means that can be used to send
heavy cargo that does not need to be send quickly, namely supplies for Mars,
and equipment for Mars).
b. Fast Cargo: Basically the humans, there for the voyage habitate and
instruments for the journey, everything that is needed for the journey out.
Stage 4: On Mars/From Orbit to Mars Surface/Surface to Orbit.
a. Orbit to Surface.
b. Station of Mars.
b2. Resupply via solar soil or slow boat.
c. Rovers/Information Gathering.
c2. Returning of information (rocks and such) to earth, via soalr sail or
other means/slow boat.
d. Surface to Orbit.
Stage 5: Return to Earth.
a. Out of Orbit.
b. Heavy Returns (soalr sil or slow boat, see 4-c2 above).
c. Light Return (humans and delicate stuff, and sensors for retuirn voyage).
d. Orbit Earth/dock with station and transfer to lander.
e. Lander on earth..
I know soem of the systems I have mentioend or used are not currently being
used..
Such as Super Gun (needs to be a larger diameter or something to get bigger
payload..Mayeb a 16 Inch Magnum Round (basically a old 16 Inch gun, bored out
for a longer shell, or have the shell be in the gun,
and the projectile be outside, much liek the old original guns of old)..
Also Solar Sail, small prototypes are in the works at the last time I heard..

Your education is severely lacking. The Dean drive is a reactionless
drive system based on swinging weights and timed application of braking
impulses. It demonstrates that a device can fool a spring scale into
indicating an object weighs less than it does. What it isn't is a real
propulsion system.

The Endeavour was an old collier converted to a Royal Navy
exploration/observation ship.
His crew included at least one botanist (Banks - who later ran Kew
gardens) and one astronomer.
It may have been armed, but in that day and age it was standard
procedure on almost all ships due to piracy, etc.

Perhaps there's no other way to stop the second stage ignition sequence

The Glomar Explorer was built by Howard Hughes' Summa Corp for the
CIA. Whoever is it's *cover* owner is rather irrelevant.

I have some new information on the DC-X flight, but first this word from
our sponsor: Do you live in Flordia? Do you want to help make the SSRT
followon a reality? Well, here is your chance!
There is an urgent need to get phone calls and letters to Senator Bob
Graham (D-FL). He is on the Armed Services Committee and he seems to be
somebody who can help get the SX-2 funded. Please write and ask him to
write Senator Nunn and ask for acceptance of the House position
on SSRT in the Senate/House conference on the DoD Authorization Bill.
His address is:
Senator Bob Graham
SD-241
Washington DC 20510
Phone: (202) 224-3041
Fax: (202) 224-6843
Some points to make in the letter/phone call:
1. Florida is the number two state for contracts on this program (especailly
Honeywell and Pratt & Whitney).
2. The followon will also mean jobs in the state.
3. Spaceport Florida will benefit from low cost access to space and will
be an excellent place DC launches.
Please write and call soon if you live in Florida. This guy is in a real
position to influence things if he wants.
Other DC news:
1. The 'burp test' went OK but had a problem. One engine cut off a second
or so early. This was due to the setting of safety parameters and not a
mechanical problem. The same thing happened often during the early static
tests so this isn't a cause for worry. They are going to reset some of the
parameters and re-run the test in a few days. Needless to say they are
being very cautious since they don't have spares. Also, some of the
parts in the DC-X are very old (one thing which made it a cheap program)
so they need to be careful.
2. The 'first flight' is currently scheduled for Aug. 28 (which conflicts
with my daughter's birthday so it looks like I ain't going :-( ). This
slip happened before the burp test so I suspect it has more to do with
range scheduling.
3. There is an article in today's NY Times (Aug 10) on DC which is very
positive. It produced a lot of interest in several groups. People at
the Department of Comerce will now be attending the flight because
of the article and ABC News was also prompted by the story to call
MacDac about doing a story. I also know that NBC news is considering
a story.
If you want to see the test flight, the best way is to convince these
media to broadcast the flight. Give them a call and ask them if they
plan to cover it. The more they hear, the more likely they will be to
cover it. Some addresses and phone numbers:
