Subject: Impediments to NASA productivity
The single most important impediment to NASA producitivity is the
systemic violation of the intent of the Hatch Act of 1939 that pervades
all sectors of our our government, not just NASA.
All of the most damaging problems that seem NASA-specific have their
roots in this central theme.
For those who don't know about The Hatch Act's intent: It was
set up, in the wake of the New Deal programs, as a way of breaking
a positive feedback loop of corruption in government via taxpayer
funds being increasingly diverted to political activities. The cold
war (the military industrial complex) and the Great Society (and the
welfare bureacracy it created) have found it is actually more efficient
to buy political support by using their funds to create incentives for
such support outside of their civil servant bureaucracies, ie: contractors
and benefit recipients respectively (although the welfare bureacracy
itself is relatively large compared to most). This is the real cause
of the takeover of government by "special interest lobbyists". NASA is
(and indeed must be) right up there with the rest of them -- even with
its own internal people flying to Washington to lobby aggressively.
(BTW: Given my history of "hate speech" against NASA, many may find
it surprising that I appear to be a NASA apologist here. My ethics
don't prevent me from being, or allowing others to be, competitive.
They just prevent me, and would prevent others, from winning cut-
throat competition and then taking no responsibility for changing the
rules that make for street brawls and select winners based on all the
wrong characteristics. NASA has shown no such ethical integrity, and
is therefore worthy of contempt -- all the more so since if NASA
didn't exist at all, it would not be capable of suppressing competition
as it has been doing in proportion to its funding since the mid to
late 60's.)
The importance of technical merit becomes disappearingly small in a
ballooning system of political feedback which, in evolutionary terms,
selects for the political expert over the technical expert -- against
positive-sum and for negative-sum gamesmanship. An immensely damaging
consequence of this, specific to civilian technology agencies such as
NASA, is that being a supposedly technical organization, the people at
the top are quite threatened by the technical experts they displace
through political means, since hard technical results are more difficult
to "argue away" when you are wrong, than "softer" results in other parts
of government. Being proven wrong in the public eye COMPARED TO YOUR
COMPETITORS is political death. That is why substantive competition must
be suppressed, at all costs, so that technical disasters, like the
Challenger, can be argued away as "doing the best at a really hard job
that NO ONE could do any better -- just give us more money next and less
pressure next time."
Let's trace NASA's problem from "the top", in the House SubCommittee
for appropriations for HUD and Independent Agencies:
People frequently complain that NASA shouldn't be grouped with
welfare bureaucracies in the appropriations process.
The actual reason this is damaging to NASA is because all of these
agencies are allowed to, and therefore must, violate the intent
of the Hatch Act of 1939 in order to remain competitive in
the appropriations process. The specific grouping doesn't
matter as a first order cause.
The sense in which NASA is at a special disadvantage in the
HUD subcommittee is that is must pay more for its supporters than
typical welfare bureaucracies. An engineer in a defense contractor
costs more than a typical welfare queen, so he isn't as efficient
a way to buy support. Also, (and this is causally related to the
previous fact) welfare bureaucracies don't really have to DO
much of anything for which they can be held accountable by the
public. Vague assertions that HUD is doing some good, for
example (perhaps buttressed by government-funded social studies),
are easy and cheap to defend to political standards of acceptability.
NASA has the possibility of failing in its missions in ways that
are relatively obvious to the public, on the rare occasions it must
attempt to fly missions. (DoD is even more inherently accountable
since so many of its people could actually die if they don't do
their jobs with a modicum of competence.)
In this respect, NASA could probably get more money if it were
placed in more direct political competition with DoD since the military
industrial complex does, ultimately, have to pay more attention to
actual performance than civilian technology agencies do. But this would
only make NASA's performance worse since it would give it more money
without changing the incentives that reward and therefore select for
political over technical merit.
Given that NASA must achieve political excellence while avoiding
actual tests of its technical abilities as much as possible, the
behaviors rewarded in NASA are the following (all are highly
correlated):
* Maximize the number of congressional districts included in any
single mission/project.
* Use the existing political expertise to suppress competition which
would be politically embarrassing.
* Minimize the number of missions/projects.
* Minimize the number of alternate routes for obtaining funding.
* Minimize the amount of freedom of technical exploration, ensuring
that all technology projects are directly attributable to one of
the few large programs and are unlikely to alter the technical
tradeoffs in such a way as to disrupt political deals with
contractors in various congressional districts.
* Maximize the duration of single missions/projects.
* Maximize funding per mission/project.
* Minimize the clarity with which mission/project objectives are
specified.
Over 20 years of such incentives have produced the NASA of today with
its terminal symptoms of bureaucratic cancer and technical incompetence.

I don't think so.
The shuttle SSME's have always been ectremely marginal.
The nose gear was kinda weak, and had numerous ops problems until
it was recently upgraded.
The brakes were too weak, the new brakes and drogue chute fix that.
The aft attach struts were too weak even by NASA standards.

Newsgroups: sci.space,alt.sci.planetary,comp.robotics
Status report on Russian Mars rover telepresence test
between Ames and Moscow:
Dave Lavery, Headquarters Office of Advanced Concepts and
Technology robotics program manager, reports that Ames
conducted the first test on Wednesday afternoon of a
remote virtual reality control system which is being
tested to operate a prototype Mars rover located in
Moscow.
This first test involved establishing a computer
connection from the control workstation located at Ames
across the Internet to the CNES facility in Toulouse,
France, and from there through a repeater to the IKI
laboratory in Moscow.
The first test was to drive the rover down a hallway in
the laboratory. A scene description model (a computer
representation of the physical conditions) of the hallway
was downloaded from the Internet from Moscow to the
workstation at Ames and was used to construct a virtual
environment at Ames of the Moscow hallway. The computer
environment was then used by the Ames operator to
visually command the rover to drive down the length of
the hallway.
(of note: This same methodology was used in this past
December's Dante robot experiment by operators from
Carnegie Mellon University located at Goddard Space
Flight Center to perform a robot control test of the
Dante robot located on the rim of Mt. Erebus in the
Antarctic. In this instance, though, the computer link
was made through the TDRS satellite.)
The only feedback to the Ames operator during the Mars
Russian rover test was a set of numerical position sensor
readings being displayed on the operator's computer
workstation monitor. Video compression and transmission
hardware and software will be installed on the rover next
week to allow the Ames remote operator to view the actual
operation of the rover as commands are sent over the
Internet.

Don't forget the desires of the politicos. Note that the big, fancy
war room with all those fancy electronic maps doesn't particularly
'enhance the mission', either; in point of fact, when they don't have
Congress or Executive staff (like the Prez or VP) in, the work takes
place elsewhere. I would assume that real-time imaging at high frame
rates would have a similar motivation -- because the 'amateurs' like
to watch.
[Since most of the real work is done by lots of people doing boring
work with stereo lenses in back rooms, there's actually no need for
'real-time imagery' at all -- store and forward would be plenty good
enough, since the time consumer is going to be the analysis on the
ground, anyway.]

Nobody said the picture would look like what you saw in the movie. We
*know* that was faked. I'm curious, though. Have you computed the
'body rate' required of the satellite to see if it's so outrageous, or
did you just take the linear velocity (high) and say, "Wow, that's a
really big number -- it can't do that!"

Ok, let's think about what kinds of capability would be required.
There are really only two numbers that are germane to this. Angular
rate of change required of the satellite and height of orbit. These
are, of course, interrelated, but I don't want to do a rigorous
mathematical treatment -- just enough to show how easy it would be.
First, the average angular rotation rate required of the satellite to
keep a specific point on the surface of the earth in view. Since you
give the average period at around 90 minutes, that says that the
satellite must be capable of 360/5400 degrees of slew per second, if
we assume that the surface of the Earth is stationary (it's not, but
more on that later). That gives a rough average of about seven
hudredths of a degree per second. Now, this does not seem to me to be
a hideously difficult rate of slew. Note that the required slew rate
will be lower than this when the satellite is low on the horizon with
respect to the target and higher when it is overhead, but even so,
these do not seem all that difficult to sustain.
Of course, there is also some 'side to side' slew necessary, since the
Earth is spinning at right angles to the path of flight of the
satellite (we usually put these things in polar orbit), but once
again, that is a predictable (and not particularly large) number.
In any case, the actual slew rates required at any given time (as well
as the changes in distance from the imaged site) are going to be
dependent upon the altitude of the satellite -- several hundred miles.
If you treat the Earth as approximately flat when the satellite is
overhead and work out the vectors, you get a rate of change for the
angle when overhead of about 15 degrees a second, which is somewhat
high but not all that outrageous. However, the rate of change of that
rate of change is rather high when directly overhead, which seems to
lead to the conclusion that they would not image in that mode when
directly overhead, but rather from slightly further down on the
horizon after the required angular acceleration needed to keep the
site in view has dropped significantly.
The conclusion seems obvious. If you can do single images of a quite
specific spot on the surface of the Earth, you can also do 30 frames
per second imaging.

This whole thread of discussion is really analagous to
comparing apples and oranges! Shuttles and the Soyuz-TM both
carry people. The Soyuz-TM has carried VERY small payloads to
MIR which were launched directly from one of the scintific
airlock ports of the space station, but the Soyuz-TM really
doesn't LAUNCH anything.
The Soyuz-TM spacecraft is lifted into orbit by PROTON, which
has some fairly impressive heavy-lift capabilities. The PROTON
was used to loft the MIR main core module, which weighed 21
tons, the KVANT 1, KVANT 2, and KRISTAL modules into orbit.

The Proton would certainly be overkill for the Soyuz TM. All Soyuzes (Soyuzi?)
have been launched by (suprise) Soyuz boosters (a/k/a SL-4, a/k/a A-2).

Yes and now. Shuttle is the only US manned spacecraft and Soyuz
is the only Russian manned spacecraft. Thus, comparing their
manned operations makes sence. Of course, Soyuz does not stand
on its own, it is a part of a system including MIR space station.
So we should rather comapre Mir/Soyuz with Shuttle.
Comparing cargo capabilities of shuttle and Soyuz spacecraft
does not make sense (Soyuz spacecraft is not designed for cargo
operations). Here the Shuttle should be compared against TITAN or
Russian PROTON launcher.

No !! Soyuz SPACECRAFT is launch by a Soyuz ROCKET. Why would anybody
use a 21ton-capable PROTON rocket to launch 6.5ton Soyuz spacecraft ?????
The name SOYUZ is used for two different things.
First, there is a Soyuz SPACECRAFT. It is a manned spacecraft for 3 people.
It carries no cargo. Currently used version is called Soyuz-TM.
Second, there is a Soyuz ROCKET. It is a three-stage rocket with a
cargo capability of about 7tons to LEO. It is used to launch Soyuz spacecraft,
but it also launches about 30-40 other payloads every year. It has also a
four-stage version sometimes called Molniya. This is by far the most
used space launcher in history. According to Flight Internationsl Launcher
Directory, Soyuz/Molnia has been launched 1260 times (as of Apr 93) with 16
failures reported.

True. But each had even larger difficulties to overcome.

New Zealand, Australia, and the Philippines did not pay for

Obviously free defense is not the only thing.
France Paid most of their own defense costs. They lost wars in both algeria

Their economy is quite fine.

Well, I have to agree that Ken's remarks were just a little beyond
logic, but I'm afraid I don't find yours much more accurate.

Uh, don't look now, but we sure seem to do a lot of business selling
weapons systems to other countries. You might also want to examine
the trade deficit with regard to Europe. You'll find we sell them a
lot more than they sell us and that part of what we sell them is
things like F-16 fighters, radar sets, etc.
So we see that Ken is pro-Defense and you are basically anti-Defense,
and neither one of you is really looking at the objective picture.
[Don't rely on my being 100% objective, either, although I try to be.
After all, I build weapons, so I do have some interest in our policies
in that area.]

Excuse me? The Germans had (and probably still have) the largest
military force in Europe, not to mention that we were going to get to
fight on *their* homes (and not ours). If you want to grouse about
someone not paying 'their fair share', talk to the French or the
Japanese.
