In fact, there are small commercial refrigerators for camping

That was someone replying to your erroneous posting about how "noise" was
such a big problem, so the response was based on your context. It almost
sounds like you now trying to use that as some sort of "evidence" ??

Groom...
I was saying that it would not likely be flying at 100K feet when over L.A.
and we know for a fact that it wasn't anywhere close to that height during
the "booms". IF for some reason "Aurora" was at 100 over L.A., it could
certainly find a "safe" way to land. The point is that there would be
no REASON for flying that high when coming in for a landing...

Something clearly labelled as speculation "confuses people"? Only
those who are confused by things like shoelaces, I would think. If
someone says, "Perhaps it . . . " I generally assume that's
sspeculation.
So your only argument comes down to the old canard about "bandwidth".
Oddly, more of that gets wasted by people complaining about wasting it
than is generally wasted by the people accused of same.

Thanks so much for making this available. Viewers might want to try

MARS OBSERVER STATUS REPORT
March 4, 1993
3:00 PM PST
Flight sequence C7 B is active. The Flight Team reports that spacecraft
subsystems and the instrument payload are performing nominally. The
spacecraft is in Array Normal Spin in outer cruise configuration, with
uplink and downlink via the High Gain Antenna; uplink at 125 bps,
downlink at the 4 K Science and Engineering data rate. The Gamma Ray
Spectrometer is taking calibration data.
DSS-15 (Goldstone 34 meter antenna) has been unavailable for tracking
for the last 2 scheduled passes due to pointing hardware problems.
Current estimates for earliest availablity is 10:00 PM this evening.
Flight Operations is working to extend scheduled DSS-45 (Canberra 34
meter antenna) coverage for purposes of gathering additional tracking
data for Navigation and Spacecraft team maneuver development inputs.
Navigation and Spacecraft teams continue final parameter development to
update Flight Sequence C8 for performance of Trajectory Correction
Maneuver 3, scheduled for March 18. The Maneuver Performance Data File
meeting is scheduled for 9:00 AM Friday. The TCM-3 velocity change will
be approximately one half meter per second, and will be performed
utilizing the 22 Newton thrusters, rather than the larger 490 Newton
units used for earlier corrections.

I'm amazed that the NASP was even funded. Back in 1978, the American Institute
of Aeronautics (Technical Committee on Space Systems) concluded that:
"One advanced Earth-to-orbit transportation concept employs a hypersonic
airbreathing launch platform using supersonic combustion ramjet ("scramjet")
propulsion combined with a rocket second stage which ascends to orbit.
It has been shown that such concepts are not economically competitive
with SSTO vehicles as space launchers unless the high costs of developing
and operating large scramjet platforms can be defrayed substantially by
sharing with various atmospheric cruise missions. Practical "commality"
or multipurpose use has been historically rare, so some form of SSTO
vehicle will remain the most promising approach to economical Earth-to-
orbit transportation for some time to come."
"Rapidly evolving vehicle concepts and technologies point to the feasibility
of fully reusable Earth-to-orbit vehicles, including single-stage-to-orbit
(SSTO) transports, by the early 1990's. Such vehicles could reduce
Earth-to-orbit transportation costs below those of the present shuttle by
factors of 50 or more, to below $5 per kilogram in orbit. The key
technologies are high-pressure and dual-fuel propulsion, low-mass cold
and hot vehicle structures, reusable thermal protection systems, and new
areodynamic concepts. These growing technologies should be supported
assiduously."
On pages 63--66, the authors describe a "Class 4 ballistic SSTO" that looks
*very* much like the proposed Delta Clipper...
The report is a relatively slim volume (91 pages) but does a good job of
putting the current situation in context.... Highly recommended.

1980-2000." New York: AIAA, 1978. (AIAA Aerospace Assessment Series,
volume I.) (TL 795.5 S63)
My question to the net: Where does the classification "Class 4 ballistic
SSTO" come from in connection with DC type SSTO's, i.e., what are class
1, 2, and 3 ballistic SSTO's?

2. Start work immediatedly on converting Freedom technology to Moon/Mars base

Don't change the subject Dennis. You asserted that batteries form a single
point failure for ALL spacecraft. You then attempt to prove the statement
by providing an example of a place where the battery WASN'T the source
of a single point failure (dispite catastrophic failure).
This is what is called a contradiction.

I don't recall ever complaining about IUS.
You still don't get it. I don't mind expensive one bit provided the funds
are efficiently spent. For example, I recently bought the most expensive
CPU board for a system I am developing. I did it because the increased
performance would yeild results better enough to justify the additional
cost. But even thou I bought the most expensive board, I still spent some
time shopping around to get the best price for my customer.
>I would not have done that, looking at the statistical

Depends. Let's see, assuming Shuttle lifts two satellites both with
IUS and let's say each satellite costs $100M. Let's also say the failure
rate without redundant electronics is 1% and .5% with redundant
electronics.
That means we are spending about $400M to get the satellite up. So if I
can provide redundant electronics for under $2 million a copy it is a
good idea.

Need to toss in my two cents about the "End o' California Drought" and
its *supposed* association with the weak enhancement of the El Nino
conditions.
First off, the current El Nino thing going on (I hesitate to call it
an "event") is much weaker than what occurred during the winters of
'86-87 or '91-92 no matter what one wishes to define an El Nino with
be it Nino 3 Sea Surface Temperatures (SST), Southern Oscillation (SOI),
outgoing long-wave radiation (OLR) over the dateline, surface westerly
anomalies in the wind. If you wish to check this out for yourself,
please look a the latest *Climate Diagnostics Bulletin* from NOAA's
Climate Analysis Center - it's free too.
Secondly, even when a "significant" El Nino is occurring, there is no
*consistent* teleconnection to Western U.S./California rainfall. Please
check out Ropelewski and Halpert, *Mon.Wea.Rev*, 1987. What *typically*
(and keep in mind that each El Nino has its individual characteristics)
is that the anomalous convection in the equatorial Central Pacific kicks
off (excites) downstream waves in the midlatitudes that have an anomalous
mid-tropospheric low in the North Pacific and an anomalous ridge along the
U.S./Canada west coast. (See early work by White and Clark, 1975, *J.
Atmos. Sci.* and Namias, 1978, *Mon.Wea.Rev.*)
With this ridge along the west coast, one expects warmer than normal
surface temperatures, but the precipitation is more difficult to anticipate.
This is because of the complicating presence of where the southerly branch of
the jet stream sets up. (Whenever a strong ridge in the westerlies is
present one often has a split flow in the westerlies occur with a southerly
branch of westerlies "beneath", or to the south of, the ridge.) If this
southerly jet sets up over California, they get wetter than normal (as it
apparently has this winter). However, sometimes the jet sets up over
northern Mexico - keeping the U.S. West dry. Note that in all the news
about a wet California and southwest, the Northwest states (Washington,
northern Oregon, northern Idaho, Montana, and the Dakotas) have had a
dry December and January.
So I guess the best way to sum El Nino/California teleconnection up is
that:
El Nino >>> Wet California (as in '82-83, '92-93)
El Nino >>> Normal California (as in '69-70, '72-73)
El Nino >>> Dry California (as in '76-77, '86-87, '91-92)
(And, again, I hesitate to call '92-93 winter a full-fledged El Nino).
(Data for above from the latest *Weekly Climate Bulletin*, also from
NOAA's CAC - also a free publication).
I hope this may help. (This is not a flame either, just my perhaps
incorrect view of the wonderful world of meteorology.)

The work *was* done by McDonnell Douglas, but it is not part of
or funded by WP2. The plume loading study was done under the Applications
Analysis Support Contract (AASC), which supports MOD and various divisions
of the Engineering Directorate.
There are a lot of contracts and contractors out there, and it is
mistake to assume that all this work is done under the Work Packages.

However, the Son of NASP seems to be in the works. This will be a very
reduced scale effort and will focus on building and flying several
prototypes rather than just one. It looks like DC-X had an influence
on them.

I agree they whern't likely to do much in hypersonics as such but from the
materials point of view it was a successful program.
BTW, large parts of the total NASP spending came from the contractors
and not the government.

Well I don't think it's that important if you have a Ph.D. or not.
I've got one in Physical Chemistry but I don't think that had anything
to do with getting my job. I think it's more important to get involved
in an area that you like, are good at, and is of some interest to NASA.
Don't get yourself into too narrow of a slot because projects change,
and come and go. If you can, try to get involved in some research
project associated with NASA, work with (for) a professor who has a
grant with NASA that way your name and abilities become known to
people at NASA and might help you get a job there down the road. If
nothing else it's good experience and a lot of fun.
Good luck,

It's not a policy but Appropriations has been very unwilling to provide
multi-year appropriaitons for NASA today (unlike Apollo when it was
routine).
>They refuse to obligate future Congresses to specific expenditures.
Only partly. A large part of the reason is that Congress believes that
NASA doesn't spend money very wisely and needs the extra supervision.
>NASA does not have the legal power to do this on their own.
No, but the Administrator can re-program fairly large sums of money
on his own. Even within an area there is a lot of freedom for the
administrator. Freedom, for example, is usually only one or two line
items. There may also be restricitons or requirements on in the bill
for station spending but the vast majority of the funds are there to
be spent as the administrator sees fit (as long as it is for station
work).
There are also a lot of 'slush funds' controlled by center managers. Some
estimates say that up to 30% of money spent on Freedom are diverted by
center managers to fund their non-station related pet projects.
So the money is there and NASA can spend it with a lot more freedom
than you think.

An assessment of the space station effort done at a high level of NASA
has shown that Freedom can be built on schedule for $2B per year *IF*
all the money where spent on Freedom.
Now this is what they have been getting from Congress for the past
few years and are likely to get for the next few years. If the money
where spent wisely we would have a station.
Can't blame congress for this.

NASA Authorization bills tend to authorize everything. Also, since they
pass after the appropriation bills the appropriation is the defacto
authorization.

Every night I drop to my knees and thank God that you are alive today
instead of in the days of Henry Ford. I can hear you say: "I'm sorry
Mr. Ford, but you can't be allowed to build your auto factory. You
would displace too many buggy whip makers and we can't have that".
My solution would be to have them work in a larger self sustaining
space economy.
