FYI: Sounds like Sagdeyev, he was the head of the IKI - space research
institute of the USSR Academy of Sciences - for several years, a fairly small
organization responsible for managing a few scientific satellites and
probes, nothing to do with Buran. He spends a lot of time now in Maryland.

reply to your 'non-reply'?  All the net.clever of the typical Frosh,

[The *speculation* [do you know the word, Larry?] with regard to
Milliken was raised by someone who was a Full Professor (not an
Associate).  Perhaps you need to learn to think a bit more freely?
Or, if your overzealous use of captitals and punctuation is any
indicator, perhaps the phrase "a bit more freely" could be replaced
with "at all"?  You aren't related to McElwaine by any chance, are
you?  He like upper case and overstatement, too.]

Gang -

It is hard to sleep in space, at least with Spacelab - it is very noisy,
with pumps and fans running constantly. It is also cold - the thermal
balance is done with a worst case heating load and so the Spacelab gets
very cool.

Several of the crew members that I have talked with have mentioned the
noise - but once you get used sleeping in space they say it is very
natural. You don't sleep under a blanket, they have sleeping bags. And
since they are in zero-g you don't have anything resting on you, you can't
pinch your arm and have it go to sleep, etc.

The other problem is excitement - eveyone wants to look out the window
sometime! At least with Spacelab Module missions there is not a window back
there, but the payload crew does escape into the mid-deck or flight deck
once in a while. And the crews are eager to get the science - so they want
to be at work.

They all come back real tired - but that does not stop them from signing up
for the next flight!

Subject: Info Req: technology complexity metrics
Newsgroups: sci.space,sci.engr.manufacturing

I'm looking for information or pointers to journal articles/books/references
or reports on the following topics. Any help will be appreciated!

Basically I want to gether information on metrics for the complexity of
large scale advance technology projects, especially those that are
space and aerospace related. I would like to get a variety of different
viewpoints, such as those from different fields like Operations Research,
Computer Science, Artificial Intelligence, Aerospace engineering,
Manufacturing Engineers and possible other domain experts.

The primary application areas I'm interested are A.I., manufacturing
in space, large scale systems and human factors.

An example of the kind of thing I would like to be able to gauge is, for
example, the relative complexity of the space shuttle versus the space
station, or the relative complexity of *developing* technology such as
a mars lander compared to a computer hw/sw system for rapid prototyping
instrumentation. i.e. I want to be able to compare (on some level)
disparate types of things or processes - so I prefer to know about
metrics which are very general as well as those specific to a domain.

If you can point me to any related information, I'll be grateful.

The *estimated* probability of something shuttle (or HST) sized taking
some sort of hit from the Perseid shower/storm has been quoted at 0.001 -
1 in 1000.  Personally, I avoid standing under trees during thunderstorms,
even thought the odds of taking a strike are much longer than 1 in 1000.
I have no problem with NASA not taking any unnecessary risks.

BTW, I understand that HST's cover will be closed to protect the mirrors
during the storm as well.  Again, better safe than sorry ...

                         MAGELLAN STATUS REPORT
                             August 6, 1993

1.  Aerobraking the Magellan spacecraft into a near circular orbit on
Venus was successfully completed on Tuesday, 8/3/93.  The apoapsis was
reduced from 8460 to 540 km, and the orbit period to 94 minutes.

2.  Magellan's periapsis was lifted out of the upper atmosphere by a
series of five Exit OTMs (Orbit Trim Maneuvers) which began early Tuesday
and finished on Thursday.  The final orbit is 540 x 197 km.

3.  The Magellan Transition Experiment demonstrates a significant new
maneuver technology by achieving a major orbit change with minimal
propellant and enabling new scientific observations near the poles of
Venus.

Magellan Significant Events for Next Week

1.  A press conference on Magellan's successful aerobraking will be
held at JPL on Tuesday, August 10 at 10:00 A.M., and broadcast on
NASA-Select.

2.  Tuesday also marks the 3rd anniversary of MagellanUs arrival at
Venus.

3.  Circular orbit operations will officially begin on August 16th.

Wait, how do you suppose to sell off the old launchers?  And why R&D is
not cheap.  With this mode every new launcher will be a proto-type.

There's also a CDROM you can buy with all of the images and music along
with the book by Sagan.  I've been told the disk is of so-so quality
so I haven't plonked down the ~$50 yet.

I need to find out where I can obtain the current state
vectors for Voyager 1 and 2. If anyone has the current
state vectors could they please post them. By state
vectors I mean (x,y,z,xdot,ydot,zdot) with respect to
the solar system's barycenter.

Thanks...

The true determinant of wing size is swept area. Since the rotary
wing travels faster than the vehicle, it's swept area is bigger than
a fixed wing. So these *are* big by wing standards.
