Subject: Carl Sagan got a Ph.D. in Astronomy, not Biology
Newsgroups: sci.space

   A while ago, several people said that Sagan had gotten a degree in
"bio-astronomy" or "astro-biology" or something; I responded that he
got a Ph.D in Astronomy and Astrophysics from University of Chicago
in 1960.  I thought it would end the discussion, but noooo...

   William Mills mentions a curious "fact" about Carl Sagan's early career.

>  When he gave his "Is there intelligent life on Earth Speech" here
> last month, he was introduced as having been an assistant professor
> of genetics at Stanford in 1962.  Unfortunately, no one asked him
> how he went from a PhD in astronomy to a faculty position in genetics.

   I have in front of me "American Men and Women of Science", 16th ed.
In the entry for "Sagan, Carl", I read:

     "Educ: Univ of Chicago, AB '54, BS '55, MS '56, PhD (astron,
      astrophys) '60.  ... Prof. Exp: Miller reseach fellow astronomy,
      Institute for Basic Research in Science, University of California,
      Berkeley, '60-'62.  Asst. prof. Harvard Univ. '62-'68.
      Astrophysicist, Smithsonian Astrophysical Observatory, '62-'68. ..."

   Whoever stated that he was "assistant professor of genetics at Stanford"
was mistaken.

   Now, this is the last I'll post concerning Sagan.  Like I said, I
don't know him, I don't worship him, I just respect him.  I've tried
to educate some of the readers of this group about his credentials,
but I expect that we'll continue to hear stories about Sagan's
"astro-biology degree" and "genetics position" and probably some
story linking him to Marilyn Monroe, as reported in the Enquirer :-)

Newsgroups: rec.games.frp.misc,sci.space,rec.arts.sf.science

It's important to understand that the Dyson sphere, as Dyson conceived
it, is *not* a preplanned, constructed object.  Instead, the
Dyson Sphere is a structure that emerges out of the efforts of
competitive cultures to capture as much stellar energy as possible.
The sphere consists of thousands of independent space colonies which
resolve blocking conflicts (mostly peacefully, eg through stellar
view property rights markets) and, as the view gets deaer,
eventually link up in equidstant orbits to form a cohesive,
all-encompassing sphere.

This concept makes the Dyson sphere radically different from
O'Neill colonies, Ringworlds, etc. which are all preplanned objects
requiring massive, centrally planned engineering projects to implement.
With Dyson, I claim that such large preplanned structures are
about as probable as the Third Reich lasting 1,000 years, the old
Soviet Union meeting its 5-year plans for an entire century, NASA
building a Shuttle/Space Station/Moon base/Mars base infrastructure
that "opens up the solar system to space settlement", and other
such hubristic central-planning nonsense.

    If the Dyson sphere is made up of large, preplanned objects like space
colonies, why is it more probable than said colonies?

The place the Keck and large ground based telescopes really do win is, of
course, not in imaging (though with adaptive optics this will improve) but in
spectroscopy, where the sky background gets spread all over the chip, while the
spectral lines you're interested in stay on the same small number of pixels.
You thus get the full benefit of the larger collecting area with few of the
detriments of collecting more background at the same time. This will mean very
large, faint galaxy surveys become possible, for example.

Except that titanium is so abundant in lunar surface material that it
has been said to qualify as medium to high-grade ore by terrestrial

Not at all.

    Columbus had enormous reason to try and reach India.  A cheaper
trade route.   The turks were making the italians and spanish merchants
insane with their freight charges over the silk road.   Plus, everyone
suspected them of holding back the best stuff.

Columbus figured that the route around was reachable in the caravels
of his time.  Of course,  he grossly exagerrated how easy the route
would have been.  Contemporary astronomers of that time had correctly
estimated the length of a westward passage and determined it was beyond
the range of current ships.   Although everyone knew there was land
over the western oceans,  they figured it must be very far away.

Had the americas not existed,  columbus would have either starved
en-route to china,  or his crew would have mutinied and forced
him to return.

God, it *is* as bleak as it sounds.  From the sounds of your description

The Sun does indeed have a ring of matter about it, but the majority of that
mass seems to have coalesced into a few dozen clumps...

Actually the part that hasn't condensed into those clumps is quite
visible under the correct circumstances. We call it the "Zodiacal
light" and it can be seen under favorable conditions before
sunrise and after sunset (low angle forward scattering) and as the
"Gegenschein" (180 degree backscattering) perhaps also, though I'm
not sure that is due to the same stuff.

Can anyone inform me better as to the location of the stuff
responsible for the Gegenschein and about the integrated absolute
magnitude of the Zodiacal light?

Yes, Pat, the sun does have a ring around it.

Also, if you know someone who doesn't read Usenet and would

If you would be interested, please e-mail me for the questions.
I'm not going to post them unless someone requests that.

Rep. George Brown Lays Down His Marker on Space Station Freedom

FYI No. 68, May 20, 1993

At a jam-packed press conference this morning, House science
committee chairman George Brown (D-California) announced that "the
Freedom-derived Station is the only design I intend to support."
Although not a surprise because of his past support for the space
station, Brown's statement is significant.  One, he is clearly not
backing away from the station.  Two, Brown is signaling to the
administration his strong preferences about the design outcome he
wants.  Brown said that while he would not actively oppose a
scaled-down design, he would not support it either.  The loss of
his advocacy would be very detrimental in what is sure to be
another bruising battle over station funding.

In an hour-long conference announcing the introduction of H.R.
2200, the NASA authorization bill for fiscal years 1994 and 1995,
the only real topic of discussion was Space Station Freedom.  Brown
seeks station funding of $1.9 billion per year for each of the next
five years.  While this total of $9.5 billion is 24% less than the
existing station baseline, or a savings of $3 billion, it is $500
million more than the Clinton Administration wants to spend.  When
asked about this difference, Brown said the administration has
compromised its original positions on other legislation, and that
such negotiating would be expected on this issue.

Brown's move is clearly intended to pressure the White House as its
moves towards its June decision on the space station.  He views
current problems as political, not technological.  Commenting on
the review, Brown said, "Although a great many innovative ideas
have surfaced -- and this has been a valuable exercise -- none of
the alternative concepts to emerge in discussion so far have the
potential to mature to the state that now characterizes the Freedom
design.  Any new concept, however attractive it may sound, will
require detailed study and development before I would feel
comfortable with any large-scale commitment.  Thus, the
Freedom-derived Station is the only design I intend to support.  If
the Nation decides not to pursue the Freedom Space Station, I would
recommend that we give much more serious consideration to our next
step than a 90-day study can provide."

The committee will wait until the design review is completed before
taking further action on H.R. 2200.  A panel of outside experts is
scheduled to review NASA's study by June 10, at which time
President Clinton will select the redesign option.  Brown said that
he would be meeting with House appropriations subcommittee chairman
Louis Stokes (D-Ohio), Senate subcommittee chair Barbara Mikulski
(D-Md), and Senate subcommittee science chairman Jay Rockefeller
(D-WVA) to establish a consensus on station funding, and will work
with the White House.

Although key congressional players may eventually rally around a
station design, the outlook before the full Congress is quite
uncertain.  Brown warned that if the recommended design is a
"harebrained" idea it would have, on a scale of 1 to 10, a "1"
chance of passage.  A station design meeting all of its
international obligations and other requirements would have, Brown
said, only a "5" chance of passage.  "This is," Brown cautioned,
"going to be a very hard sell to Congress."

According to this weeks space news,  The Johnson "GEODE"
concept looks like it's back to life again.  Although not under
consideration by the O'Connor panel,  Johnson thinks only
Geode can meet the cost guidelines imposed by Clinton.

Personally I think Geode is the way to go.   You get quick
assembly,   the core truss concept remains,   it's expandable
and it meets the internationals  requirements.

It can go up in a high orbit for russian collaboration
and Johnson claims it can be done for 7 Billion.

If all the major concepts break budget,  then we may look

No, I don't know of any other references that would pry into the
private lives of the Grissoms in this way.  If you're really that
concerned about whether or not "The Right Stuff" is fact, I really
think it would be more appropriate to dwell on the facts, rather
than prying into (and disputing!) people's personal feelings.

Friend, you don't seem to understand that there's a difference between
distorting facts and simply interpreting, as best one can, emotions
and feelings that only one person can truly know.  Wolfe wasn't in the
motel room with the Grissoms.

   What's the latest on the first launch of Delta Clipper X?  It has to be
