Is it possible to recover his capsule now with modern
sallvage techniques or would it probably be buried in muck
beyond recovery?
It'd sure make an interesting artifact for a maritime museum.

When in 1994 will the comet collide with Jupiter.
I have to arrange my vacation schedule!
I guess its too early to tell if it will be visible
from North America.
This event would definitely be worth an observing trip
to another continent. I'd guess it's a once in a
millenium event!!

Newsgroups: sci.space,sci.astro
Latest IAUC says that, based on the current orbital solution,
the entire train may collide with Jupiter. The trail has the
best chance of missing, which is interesting as it will
then be flung into (a family of) heliocentric short
period orbits - possibly Earth crossers!
Yeomans at JPL quotes 0.64 prob of collision given
current orb params.
So, where in the sky will Jupiter be July next year?
If it hits, observations should probably be done by
high resolutions ground based scopes (maybe CFHT and
Keck if in position) and fast CCD imagers and spectrometers,
Jupiter is order arcminute across on average (assuming
I did me 'rithmetic rite), so large fields of view help.
Wonder which hemisphere will be lucky, still, with Hawaii
and the Canaries the globe is pretty well covered...

Subject: How would we get back to the moon, if we had to?
Newsgroups: sci.space
A year or so ago, there was a long discussion in this newsgroup
about how we would get back to the moon, if it was necessary
to do so. The most of the discussion centered around whether
we would try to resurrect the couple Saturn V's laying around
in museums, and reconstruct the Apollo program, or whether we
would simply start from scratch. The consensus seemed to be
that we would go the latter route, because the technology has
changed so much in the past 20-25 years.
I'm working on a think-piece concerning the future of the nuclear
weapons complex, and this strikes me as a useful analogy. Any
debate about nuclear weapons should be directed to another newsgroup
(although if anyone has feelings about the validity of this analogy,
I'd be happy to hear them via email: bpw@ctxsys.lanl.gov), but
I need some info about the state of the technology used to build
the Apollo program. In particular:
1) For what subsystems has the technology changed the most? (I'm
guessing it's the computers/electronics)
2) What was the state of the computer technology in the Apollo program
(ie. was it even as sophisticated as, say, an 8008?)
3) Are there any techologies used in the Apollo program which are
now long out of use, or simply not available?
4) What do you think about the question posed above, if there was
a compelling reason to get back to the moon FAST? Would (could?)
we simply resurrect equipment from museums? Would we use the
major pieces, updating the electronics, etc. as necessary?
Or would it be fastest to simply start all over?

But you don't want a useless object. Those earth-crossers have what the
moon lacks: volatiles. Unless _all_ of them would be lost by a collision,
it would be nice to create a few resource sites on the Moon.

Subject: Mining on the Moon?
Newsgroups: sci.space
Has anyone read Heinlen's "The moon is a harse Mistress"
in which an inertial catapult is used to sling large loads of ore surrounded by
a metal jacket with braking thrusters to Earth. Is this a practical option -
can it be done and if so would it be to expensive?
I don't know what the extent of mineral resources on the moon are or wether they
are worth mining but if the transportation was cheap enough ie. just put it on
this catapult with a metal jacket around it and some thrusters and you can
deliver it anywhere on Earth, then it might the practical.
Can anyone help me
- is this practical, can this system be set up?
- what are the type and extent of the mineral resources on the moon?
- has this idea been explored seriously before?

Any closed cycle environment is going to rely on biology. We really
know nothing about how Earth life will react to Mars gravity. LEO can only
give you zero-g, unless you put up a big centrifuge. (The Space Station,
at least before the current redesign, included a small centrifuge, which
could handle some biology testing, but not a whole biological closed system.)
The Moon at least gives you low gravity: if Earth life can do well in long
term lunar gravity, it's a good bet it can handle Mars gravity.

Remember Jamestown: a colony in a malarial swamp near fertile high ground.
It survived for about 90 years because it was on the water, and had easier
transportation back to England. A Moon Base would have a similar advantage
over Mars or asteroids.

Sour grapes? Is this truly a legitimate reason to be opposed to human space

Subject: Space Station Freedom Paper Sim #3
Newsgroups: sci.space
Boy, that was fun! Yesterday, we held Paper Simulation #3 for the
Space Station flight controllers. This was a stand-alone sim. To gel
my thoughts on the sim, and to let you folks out on Usenet know what's
going on in Space Station Mission Ops, I'll post a summary to the
'Net. Since you folks can't be expected to have all of the training of
flight controllers, I'll try to explain the arcane terms and concepts
involved.
Flight controllers are the folks here in Houston who help the
astronauts keep track of their systems, plan their procedures, and send
commands up to their spacecraft.
A "Paper Sim" is a sim in which we don't use the computers in the
Consolidated Control Center (CCC) (we actually used the Shuttle Mission
Control Center [MCC], Flight Control Room number two [FCR-2]).
A "stand-alone sim" is a sim in which the role of the astronauts is
played by training personnel, not actual astronauts. This is the
antonym of an "integrated sim," in which the crew is in the spacecraft
simulator.
The purpose of this sim was to help flight controllers become familiar
with the handover of duties and information from one shift of the
flight control team (FCT) to the next. This was the first SSFP sim
which had such a handover.
The Mission Operations Space Station Training folks set up the sim
scenario as follows: the Space Shuttle Orbiter was docked with the
Space Station Freedom (as defined by the current baseline, not any of
the redesign options NASA is examining). This was Mission Build flight
6 (MB-6), Flight Day 4 (FD4). The Training folks gave us pieces of
paper containing the Initial Conditions (IC's) describing differences
between the planned situation at MB-6, FD4 and the sim scenario. In
the IC's, (1) the crew complained that the air temperature in the node
and the lab were too high, and (2) there was a leak in the Thermal
Control System (TCS) radiator number 1. The TCS radiators are
considered an Orbit Replacable Units (ORU's), which means that they can
be changed out and/or repaired on orbit. The TCS radiators reject
waste heat from SSF systems. IC #3 told us that we had already
activated audio and video communication with the SSF. IC #4 was that
there was some crew exercise (treadmill or stationary bicycle or
something -- I'm not sure which) scheduled for FD4. IC #5 was that the
Total Hydrocarbon Analyzer (THA), which is a redundant part of the Air
Revitalization (AR) subsystem of the Environmental Control and Life
Support System (ECLSS), was not operational, not recoverable, and would
be swapped out on MB-7. Other IC's: the Space Radiation Analysis Group
had forecasted heavy solar activity for the next 12 hours, so we were
no-go for extra-vehicular activity (EVA or space walks).
The leak in TCS radiator 1 was only about .6 pounds of Ammonia
(.6 pounds per what? I dunno), which the Thermal folks (console
position THOR in the CCC) determined was not really critical. THOR
eventually isolated the leak to the A side of radiator 1, which allowed
the B side to circulate ammonia normally (but that leaves radiator one
in a "one-failure-away-from-death" situation). But the leak made it
really necessary to deploy radiator 2.
At GMT 14:10:00, the FCT commanded radiator deploy. The crew confirmed
that they could see the radiator moving, and the FCT could see
telemetry which reported that the motors were going. Suddenly, when
radiator 2 was 75% deployed, it stopped. The ODIN flight controller
(Onboard Data, Interface and Networks) determined that their telemetry
object list (TOL) indicated no problem with the built-in test (BIT).
By 14:53:00, the FCT had determined that the problem was in a remote
power controller (RPC). The PHALCON flight controller started the
procedure to trouble shoot the RPC. The result was negative; we had
a failed RPC. That radiator wasn't gonna deploy.
Meanwhile, Propulsion Module 1 had a failed Multiplexer/Demultiplexer
(MDM). The SEECO (Station Enviromental, Electrical and Communications
Officer) flight controller reported that a delta-pressure gauge in the
node 2 hatch was going bad. The OSO (Operations Support Officer)
flight controller reported that there would be a problem in the present
configuration if we had to have the Shuttle un-dock, go home, then come
back; the re-docking forces would cause the radiators to collide.
However, the only way to fully deploy the radiator at this point was an
EVA, which was contra-indicated because of the solar radiation hazard.
Basically, we were stuck.
Just before the end of the day-long sim, the Training folks sent us a
note telling us that the solar radiation warning was rescinded, and we
were go for EVA.
Much more happened, but I'm out of time. Have a good weekend.

It is bad when his politics tells him to discard science and tell lies in the
guise of science. In the nuclear winter flap, his cohorts used the flexibility
of the modelling approach to tune the parameters for the worst possible result;
this, then, was used to trumpet the fact that nuclear war is bad (OK, folks,
hands up -- how many in the audience here were saying to themselves, "Gee,
I thought nuclear war was a splendid idea until TAPPS proved their nuclear
winter idea!"). More careful work, using model parameters based on reality
rather than results, indicated a much less severe outcome (the "nuclear autumn"
result). Now, of course, anything Sagan says about much of anything can be
cheaply rebutted with the suggestion that he's probably jiggered his data to
bolster a bogus claim: big help, Carl.
The problem is not "balancing science, politics, morality, reality, etc..."
It is having one's politics or morality convince one to claim that one's
statements are scientific or represent reality when, in fact, neither is the
case.

If we are going to bust on Sagan, we should get together
and lynch Teller. He's a much worse offender.
