The original article was correct. A calorie is defined as the amount of heat
required to raise one milliliter of water one Celsius degree. A kilocalorie
is 1000 such beasts. The "calorie" listed on food packaging is really the
kilocalorie with the "kilo" dropped for convenience.
Otherwise, can you imagine a blond fashion model reading a diet Coke can
saying "only 1000 calories per serving"?

2800 kcal/day is correct. The unit of food energy content, often sloppily
called a "calorie", is in fact a kilocalorie by the normal scientific
definition of "calorie".

A kilocalorie is often called a Calorie. Some ignorants change the
case, making it a calorie.
(the `big C' Calorie term for a kilocalorie has been around for decades).

definition of "calorie".
Not only that, the correct nomencalture is that 1 kilocalorie = 1 Calorie

The key summary of Feynman's report, IMHO,
was along the lines of:
"For a successful technology, reality must take precedence
over public relations, for Nature can not be fooled."
The decision-making process where P.R. goals and the desire
to get along with management goals took precedence
over real-world limits is insidious. NASA needed to make
sure it was eradicated (at least w/r/t go/no go decisions).
After the SSME hydrogen leak episodes, I felt like NASA
management had demonstrated the lesson as learned.
But now I wonder if we see signs of a shift towards
the old insidious attitudes. Urgh. in AW&ST Oct 26 '92,
pg. 15, _NewsBreaks_, _Columbia Begins Mission 52_ :
"the mission management team granted last-minute rule
waivers to permit the launch in wind conditions which
exceeded the normal limits and under conditions likely
to impose excess structural loads."
"The weather waiver was granted despite reservations
expressed by Jeff Bantle, mission flight director,
who said he considered the weather ''no go," but that
he would ''execute the launch.''
(pardon me if Mr. Spencer has already covered this)
The article goes on to say that the weather waiver was
granted (regarding crosswinds on the KSC runway in event of
RTLS abort, I assume):
"...after the [management?] team determined the average
wind velocity value was less than the maximum permitted."
The loads prompting the load waiver were not reached
during launch, but the gust limit (15 kt) was exceeded
(during the period an RTLS might have occurred, I assume).
I wonder who asked for the waivers? I suspect everything
was still within some tolerance which exceeds the normal
limits. On the other hand, is the flight director being
quoted in context? In any case, average wind velocity
seems to be a slightly half-baked basis for a decision.
Is there a followup to this story, esp. regarding Mr.
Bantle's comments, and the relevance of the particular
safety limits? Certainly the AW&ST article makes me
feel a bit uneasy. It's not enough to make me believe
the attitudes that led to the Challenger accident are
affecting shuttle operations again.

Nope; I've only just read it, in fact. First the Canadian post orifice has
to deliver it to my PO box (takes a while), then I have to pick it up (I only
clean out the box about once a week), then I have to read it (usually fairly
quick), and then I have to post it. My rule of thumb is that I'm doing fine
if posting date is one month behind cover date.

One of the important benifits of a lunar ground based (and therefore
more easily maintained, IF there is some kind of permenant base on
the moon) power, is the possibility of powering obital or other craft
with power requirements exceeding feasible solar cell array production.
An excess(!) of power could even be used to supply power to incoming
craft landing on the moon - thereby reducing total craft weight by
reducing fuel carried.

Newsgroups: sci.space,sci.astro,alt.sci.planetary
MARS OBSERVER STATUS REPORT
November 13, 1992
11:00 AM PST
Launch +49 Days
Flight Sequence C3 C continues executing toward its completion on
November 17. Magnetometer and Gamma Ray Spectrometer instrument
teams are receiving early cruise calibration data. The Mars Observer
Camera "bakeout" is continuing through December 28.
A new Star Catalog/Ephemeris was uplinked and a successful "USE"
command radiated this morning. The ephemeris previously used had the
intended effect of altering the solar array sun incidence angle by 5
degrees, from 60 degrees to 55 degrees. This sun incidence angle periodic
decrease will be performed in subsequent ephemeris loads, with the final
objective being to point the high-gain antenna at earth by the time
transition from inner to outer cruise takes place. The current offset is
designed to prevent direct sunlight on the solar panels creating an excess
amount of power. At the time of transition from inner to outer cruise, the
spacecraft will be of sufficient distance from the sun that excess power
is of a lesser concern.
Uplink of the C4 sequence is planned for November 16. C4 will begin
execution at 8:00 AM, PST, upon completion of C3 C. C4 is 28 days in
duration and continues the MOC bakeout, performs Radio Science Ultra
Stable Oscillator tests, Modulation Index Test, Radio Frequency Subsystem
Automatic Gain Control and Command Data Unit Signal to Noise Ratio
tests, and a Static Phase Error test.
The Spacecraft Team reports that all Mars Observer subsystems continue
to perform well.
Today, the spacecraft is 8,793,376 miles from earth, traveling at a
velocity of 8,106 miles per hour. One way light time is approximately 47
seconds.

I agree with all that - I believe I discuss it in a followup post. But
based on my interpretation of several sources, the mascons of Earth have
little or no perceptible effect on orbiting spacecraft (in the sense that
you don't have to allow for them in your calculations when putting your
spacecraft into a selected orbit). I believe this is because the Earth
mascons are generally less intense than those on the moon, and because the
gravitational field of the Earth is so much greater than that of the moon that
the mascons have a much smaller relative influence on spacecraft trajectory.
(Again, the equatorial bulge does not count as a mascon.)

Sorry, won't work. Not unless the individual telescopes in your array
are pretty spectacular instruments in their own right.
You need around 10 meters of unobscured aperture, with a mirror
perfectly figured and smooth to .01 lamda, to keep the light from the
planet from being lost in the statistical noise of light diffracted
from the primary. And even that's only adequate for the dozen or so
nearest stars.
The problem is that, for a terrestrial planet at optical wavelengths,
the light any telescope receives from the planet will be ten orders
of magnitude below (one ten-billionth) the light from the primary. If
planet and primary were of equal brightness, a one meter space tele-
scope could resolve them. But as it is, it would take nearly perfect
diffraction-limited optics of ten times that aperture to concentrate
the planet's light enough to detect it above the far-field light haze
from the primary.
But, you ask, so what? Won't mixing the signals from the combined
telescopes in the array isolate the light from the planet? Well, yes
and no. You can boost the signal-to-noise ratio by an amount that's
proportional to the number of telescopes in the array. That might
allow you to detect the presence of the planet, where you couldn't
otherwise. But unless you start with a pretty clean signal in the
first place, there will be far too much noise to allow anything like
imaging of continents.
People talk a lot about the fantastic resolving power of wide baseline
arrays. You can do neat things with them, but when signal-to-noise is
an issue, it's total real aperture that counts.

Me cynical about NASA? Nah -- they're the only game in town. I just object
to excessive razzle-dazzle, and attempts by certain of their employees to
push the Shuttle as the best way to accomplish NASA's goals. Goldin is better,
basically admitting that they're stuck with it. The best thing about the meetings
is that they're happening near many of you! By all means try to attend. A note
on procedure that I've sent to NASA with my other comments: the 2nd stringer
segment (i.e. panel of NASA program managers) would improve if the panel members
were introduced *before* the final segment so that you could question them 1-on-1
during the break. I suggest that you arrive early & find the managers you want
to talk to about specific issues, because you can't monopolize the open mikes.
Queue fast ... Goldin fielded < 15 questions.
My responses to Bill's questions:
>1. Do you think this meeting accomplished anything? If so, what?
Yes. Goldin gave a good summary of how NASA is attempting to address
budgetary concerns, why NASA is essential for high-tech development for
US industrial development, and the use of space as an educational magnet.

Officially, the whole experience will end up as a few sentences in some

1. Do you think this meeting accomplished anything? If so, what?
2. Do you think this meeting (or the whole series of meetings) will
accomplish anything that you want accomplished? (-:
I may ask these questions again as the meetings go on across the
nation. I'm curious about the reactions of net.people to Goldin's
effort.

ULYSSES MISSION STATUS
November 13, 1992
All spacecraft and science operations are performing well.
Routine Earth-pointing maneuvers are continuing to be conducted
about twice a week. The last set of maneuvers were performed on
Nov. 6 and 10. The next maneuver will be carried out on Nov. 14.
A reduction in the number of ranging passes continued during
this reporting period to improve the spacecraft signal at its
great distance from Earth. Today Ulysses is about 830 million
kilometers (515 million miles) from Earth, traveling at a
heliocentric velocity of about 32,400 kilometers per hour (20,200
miles per hour). Ulysses is now 12.7 degrees south of the
ecliptic plane in which the planets orbit, slowly looping its way
back toward the sun.
The Keppler Gas Experiment that measures neutral helium gas
from interstellar space was turned on today. Measurement of the
arrival speed and direction of the interstellar gas allows
scientists to determine how our solar system is moving through
interstellar space. Now that Ulysses has climbed almost 13
degrees out of the ecliptic plane, it is possible to determine
speed and direction more accurately by including measurements
made in the third dimension.

It's about time. NASA has to train its new pilot astronauts how to use analog
instruments, they're all used to modern military cockpits, and the shuttle
looks like the inside of a 707.
