Subject: Satellite Microcontrollers

In my software engineering class today, we discussed using non-state of
the art technology because of the dependability factor.  (i.e. something
that has been around 10 years has been thoroughly debugged, in theory)

The topic of satellite controllers came up, and a 4 bit microprocessor
was mentioned that was reputed to be highly radiation resistant. It was
called an ELF.

My question is, does anyone have any information on this microprocessor?
If so, could those who do have information on specifications, availability,
etc. mail this information to me at:

[e-mail] (preferably) or this account if necessary.

thanks,

Eric

I have frequently wondered why the "best" voyager photos haven't
been collected in a book.  It seems like it would sell well, and
hopefully advance the cause of science.  Pardon me, Science.  Does
anyone know if plans for such a book are in the works?

RELEASE:  89-169

NASA APPOINTS SPACELAB PAYLOAD SPECIALISTS

     Dr. Lennard A. Fisk, NASA's Associate Administrator for
Space Science and Applications, recently appointed two Spacelab
payload specialists.  Dr. Millie Hughes-Fulford will be a prime
payload specialist for Spacelab Life Sciences-1 (SLS-1) and Dr.
Stanley N. Koszelak will serve as the U.S. backup payload
specialist for Spacelab-J.

     Hughes-Fulford, 43, previously assigned to Spacelab Life
Sciences-2 as the prime payload specialist, has been reassigned
to SLS-1 to replace Dr. Robert W. Phillips, 60.  Phillips is
stepping down because he did not meet the medical standards for a
payload specialist.  He will continue his duties as an SLS-1
mission support team member.

     Hughes-Fulford is an associate professor of biochemistry at
the University of California Medical Center, San Francisco, and a
medical researcher at the Veterans Administration Medical Center
in San Francisco.

     SLS-1 is the first mission to use Spacelab, a laboratory
that fits in the Space Shuttle cargo bay, as a biological
research facility.  The 20 scientific investigations onboard will
help answer critical questions about the way humans adapt to
microgravity and readapt to Earth's gravity.

     Koszelak, 36, is an assistant research biochemist at the
University of California at Riverside.  As the U.S. backup
payload specialist for Spacelab-J, Koszelak will perform critical
ground support duties during the mission.  Spacelab-J is jointly
sponsored by NASA and the National Space Development Agency of
Japan.  A Japanese payload specialist also will fly on Spacelab-J.

     SLS-1 is scheduled to fly in August 1990 aboard Space Shuttle
orbiter Columbia and is managed by the Johnson Space Center,
Houston, for NASA's Office of Space Science and Applications
(OSSA), Washington, D.C.  Spacelab-J, scheduled to fly in June
1991, is managed by the Marshall Space Flight Center, Huntsville,
Ala., for NASA's OSSA.

That's going to be some nudge; what are you going to use for propulsion
for that?  Galileo used the biggest upper stage NASA had, and would have
preferred a bigger one.  (The point here is not that one would use shuttle
upper stages for a large planetary transport, but that the propulsion
requirements for a Galileo-type trajectory are *not* just a "nudge".)

"Comparatively quick"?  Can you elaborate on this?  Even after Galileo's
fiddling around in the inner solar system, its transit time to Jupiter
is still measured in years.  Human exploration of the outer solar system
is difficult, verging on impractical, unless propulsion is good enough to
let you forget about economy orbits and use fast ones instead.

VPHD access platforms were positioned and the four J-hooks were
installed last night.  Alignment is scheduled for today.  Waste
drums were installed, and modem line patching method from CDSC
to Astrotech is in engineering assessment.

Subject: galileo and me

When I was a kid, my folks would get the whole family
up at 5:00 AM to watch the Mercury and Gemini launches.
This helped to instill in me a lifelong love of science
and engineering in general and space in particular.
Now it is my turn.
My daughter Madelaine was born at 0149 on October 18, 1989.
Later that evening, Galileo left for Jupiter.
I knew my universe had changed when I
realized that she would be starting school when it got there.
I look forward to teaching her about space.
We are thinking about giving her age in miles from earth but
that will increase and decrease as Galileo loops around
the solar system. Perhaps we should use total miles travelled.
It's going to be grand!

Subject: Information sources for frequent space questions (1 of n)

Many space activies center around large Government or International
Bureaucracies.  In this country that means NASA.  If you have basic
information requests: (e.g., general PR info, research grants, data,
limited tours, and ESPECIALLY SUMMER EMPLOYMENT (typically resumes
should be ready by Jan. 1), etc.), consider contacting the nearest
NASA Center to answer your questions.

EMail typically will not get you any where, computers are used by
investigators, not PR people.  The typical volume of mail per Center is
a multiple of 10,000 letters a day.  Seek the Public Information Office
at one of the below, this is their job:

NASA Headquarters (NASA HQ)
Washington DC 20546

NASA Ames Research Center (ARC)
Moffett Field, CA 94035
[Santa Clara, CA, near San Francisco Bay, you know Silicon Valley 8-) ]

NASA Goddard Space Flight Center (GSFC)
Greenbelt, MD 20771
[Outside of Washington DC]

NASA Lewis Research Center (LeRC)
21000 Brookpark Rd.
Cleveland, OH 44135

NASA Johnson Manned Space Center (JSC)
Houston, TX 77058

NASA Kennedy Space Flight Center (KSC)
Titusville, FL 32899

NASA Marshall Space Flight Center (MSC)
Huntsville, AL35812

NASA Langley Research Center (LaRC)
Hampton, VA 23665
[Near Newport News, VA]

Not a NASA Center, but close enough:
Jet Propulsion Laboratory [JPL/CIT]
California Institute of Technology
4800 Oak Grove Dr.
Pasadena, CA 91109

There are other small facilities, but the above major Centers are set up
to handle public information requests.  They can send you tons of information.

Specific requests for software must go thru COSMIC at the Univ. of Georgia,
NASA's contracted software redistribution service.  You can reach them
at [e-mail].

NOTE:  Foreign nationals requesting information must go through their
Embassies in Washington DC.  These are facilities of the US Government
and are regarded with some degree of economic sensitivity.
Centers cannot directly return information without high Center approval.
Allow at least 1 month for clearance.  This includes COSMIC.

Appropriate addresses (PR) to be added when determined:

ESA: European Space Agency
[Reachable at NASA HQ]

JSA: Japanese Space Agency
[Reachable at NASA HQ]

Add your country here.

Clearly Mr. Neff cannot see the difference, but that does not give him
any status in telling the rest of us.  If you have to spend your whole
life in some statist country, how much does it matter which country?

Of course it matters.  I would expect any reasonably intelligent person
to give many reasons why someone would want to live on the moon.  And
living underground does not mean all the time is spent underground.

Frankly, I can find no great advantage to living in an aboveground house
compared to the same quality house underground.  That does not mean that
Mr. Neff does not.  Assuming that we can find a way for people to live in
the moon and be productive, people will want to live there, and should live
there.
