Are breathable liquids possible?

I remember seeing an old Nova or The Nature of Things where this idea was
touched upon (it might have been some other TV show).  If nothing else, I know
such liquids ARE possible because...

They showed a large glass full of this liquid, and put a white mouse (rat?) in
it.  Since the liquid was not dense, the mouse would float, so it was held down
by tongs clutching its tail.  The thing struggled quite a bit, but it was
certainly held down long enough so that it was breathing the liquid.  It never
did slow down in its frantic attempts to swim to the top.

Now, this may not have been the most humane of demonstrations, but it certainly
shows breathable liquids can be made.

Subject: Billboard/Station/Space Dock?
Newsgroups: sci.space

Seems that the Mile-Long Billboard and any other inflateble space
object/station or what ever have the same problems. (other than being a little
bit different than the "normal" space ideas, such as trusses and shuttles)

But also dag and such.. Why not combine the discussion of how and fesibility to
the same topic?

I personnelly liek the idea of a billboard in space. But problem. How do you
service it? fly a shuttle/DC-1 to near it and then dismount and "fly" to it?
Or what?? or havign a special docking section for shuttle/DC-1 docking?

Also what if the billboard springs a leak? Self sealing and such??


Just thinking (okay rambling)..

Also why must the now inflated billboard, not be covered in the inside by a
harder substance (such as a polymer or other agent) and then the now "hard"
billboard would be a now giant docking structure/space dock/station??

Or am I missing something here.. (probably am!?)

COMET (Commercial Experiment Transport) is to launch from Wallops Island
Virginia and orbit Earth for about 30 days. It is scheduled to come down
in the Utah Test & Training Range, west of Salt Lake City, Utah. I saw
a message in this group toward the end of March that it was to launch
on March 27. Does anyone know if it launched on that day, or if not,
when it is scheduled to launch and/or when it will come down.

I would also be interested in what kind(s) of payload(s) are onboard.

Thanks for your help.

The Command Loss Timer is part of the fault protection scheme of the
spacecraft.  If the Command Loss Timer ever countdowns to zero, then the
spacecraft assumes it has lost communications with Earth and will go
through a set of predetermined steps to try to regain contact.  The
Command Loss Timer is set to 264 hours and reset about once a week during
the cruise phase, and is set to a lower value during an encounter phase.

If I'm not mistaken, this is the usual sort of precaution against loss of
communications.  That timer is counting down continuously; if it ever hits
zero, that means Galileo hasn't heard from Earth in a suspiciously long
time and it may be Galileo's fault... so it's time to go into a fallback
mode that minimizes chances of spacecraft damage and maximizes chances
of restoring contact.  I don't know exactly what-all Galileo does in such
a situation, but a common example is to switch receivers, on the theory
that maybe the one you're listening with has died.

INteresting question about Galileo.

Galileo's HGA  is stuck.

The HGA was left closed,  because galileo  had a venus flyby.

If the HGA were pointed att he sun,  near venus,  it would
cook the foci elements.

question:  WHy couldn't Galileo's  course manuevers have been
designed such that the HGA  did not ever do a sun point.?

After all,  it would normally be aimed at earth anyway?

or would it be that an emergency situation i.e. spacecraft safing
and seek might have caused an HGA sun point?

Oh, and us with the big degrees don't got imagination, huh?

The alleged dichotomy between imagination and knowledge is one of the most
pernicious fallacys of the New Age.  Michael, thanks for the generous

You, on the other hand, are letting your own dreams go to waste by

which would give your imagination wings.

For the first 100 - 500 (IMHO) years nobody will have to.  The colonists will

Again, the tie that binds will be much stronger for space colonists than
any immigrants that have gone before.  Even those intrepid Asian

Tom's right about this.  It's only a grantable right if the granter has
the will and the ability to stop anyone from taking it away from you.
Never mind the legal status.

Nick's right about this.  It's always easier to obtain forgiveness than
permission.  Not many people remember that Britain's King George III
expressly forbid his american subjects to cross the alleghany/appalachian
mountains.  Said subjects basically said, "Stop us if you can."  He
couldn't.

>If you go to the moon as declare that you are now a soverign nation, who will

That's how the USA started.  Of course, that's also how the Bolivarian
Republic started (ca. 1800-1820) in central america.  It didn't have
quite the staying power of the USA.  I'm sure there are more examples of
going far away and then ignoring authority, but none jump to mind right
now.

Or do as some whaling nations do: define whatever activities you want to
carry out as "scientific research" which just coincidentally requires
the recovery of megatonnes of minerals (or whatever), then go at it.

Lute Keyser had just this sort of arrangement with Libya (I think) in
the late '70's for his commercial space launch project (one of the very
earliest).  It was killed by Soviet propaganda about NATO cruise
missiles in Africa, which made Libya renege on the arrangement.

In my last post I referred to Michael Adams as "Nick."  Completely my
error; Nick Adams was a film and TV actor from the '50's and early '60's

Okay, Del, so Michael was being unfair, but you are being unfair back.
He is taking college courses now, I presume he is studying hard, and
his postings reveal that he is *somewhat* hip to the technical issues
of astronautics.  Plus, he is attentively following the erudite
discourse of the Big Brains who post to sci.space; is it not
inevitable that he will get a splendid technical education from
reading the likes of you and me? [1]

Like others involved in sci.space, Mr. Adams shows symptoms of being a
fledgling member of the technoculture, and I think he's soaking it up
fast.  I was a young guy with dreams once, and they led me to get a
technical education to follow them up.  Too bad I wound up in an
assembly-line job stamping out identical neutrinos day after day...

They aren't going to leave a loophole as glaring as space mining.  Quite a
few of those people are, when you come right down to it, basically against
industrial civilization.  They won't stop with shutting down the mines here;
that is only a means to an end for them now.

The worst thing you can say to a true revolutionary is that his revolution
is unnecessary, that the problems can be corrected without radical change.
Telling people that paradise can be attained without the revolution is
treason of the vilest kind.

Trying to harness these people to support spaceflight is like trying to
harness a buffalo to pull your plough.  He's got plenty of muscle, all
right, but the furrow will go where he wants, not where you want.

RELEASE:  93-76

HUBBLE TELESCOPE SERVICING MISSION SCHEDULED FOR ELEVEN DAYS

    The December flight of Endeavour on Space Shuttle mission STS-61 to
service the Hubble Space Telescope (HST) has been scheduled as an 11 day
mission designed to accommodate a record five spacewalks with the capability
for an additional two, if needed.

    The decision to schedule five extravehicular activities, or EVAs, was
reached following extensive evaluations of underwater training, maneuver times
required using the Shuttle's robot arm based on software simulations and actual
EVA tasks on previous missions.

    "Basically what we've done by going to five EVAs rather than three is
to repackage our margin so that we have the capability to respond to the
dynamics, or unknowns, of spacewalks," Mission Director Randy Brinkley said.
"It improves the probabilities for mission success while providing added
flexibility and adaptability for reacting to real-time situations."

    In laying out the specific tasks to be completed on each of the
spacewalks, officials have determined that changing out the gyros, solar arrays
and the Wide Field/Planetary Camera (WF/PC) and installing the Corrective
Optics Space Telescope Axial Replacement (COSTAR) are priority objectives
during the mission.

    "When we looked at accomplishing all of the tasks, highest through
lowest priority, and recognizing that the major tasks -- gyros, solar arrays,
WF/PC and COSTAR -- would consume most of the time set aside for each
spacewalk, five EVAs were deemed appropriate," said Milt Heflin, Lead Flight
Director for the mission.

    While the five spacewalks will be unprecedented, the use of two
alternating spacewalk teams will alleviate placing more stress on the crew than
previous missions requiring two, three or four EVAs.

    "We have paid close attention to lessons learned during previous
spacewalks and factored these into our timeline estimates for five EVAs,"
Heflin said.  "In planning for all Space Shuttle missions, it is necessary to
formulate a work schedule that represents as realistic a timeline as possible
to accomplish the mission objectives."

    Planning currently calls for at least five water tank training sessions
that include support from the Mission Control Center, called joint integrated
simulations, lasting between 10 and 36 hours.  In addition, many stand alone
underwater training "runs" will practice individual tasks in each spacewalk.

    Various refinements to the specific tasks on each spacewalk will be
made based on actual training experience during the months prior to the
mission.  Also, lessons learned from other spacewalks leading up to the flight
will be valuable in assisting the STS-61 crew in its training techniques.

    Endeavour's June flight and Discovery's July mission both will include
spacewalks to evaluate some of the unique tools to be used on the HST mission.
The evaluations will help in better understanding the differences between the
actual weightlessness of space and the ground training in the water tanks at
the Johnson Space Center, Houston, and the Marshall Space Flight Center,
Huntsville, Ala.

    Also, the inflight spacewalking experiences will assist in gaining
further insight into the time required for the various tasks and expand the
experience levels among the astronaut corps, the flight controllers and
trainers.

    Designed to be serviced by a Space Shuttle crew, Hubble was built with
grapple fixtures and handholds to assist in the capture and repair procedures.

    The telescope was launched aboard Discovery in April 1990.  At that
time the NASA mixed fleet manifest showed the first revisit mission to HST in
1993 to change out science instruments and make any repairs that may have
become necessary.

The problem is, you can't raise adequate amounts of money that way.
The Viking Fund tried.  They did succeed, in a way, but only because
of the political impact of their fundraising.  The actual amount of
money they raised was fairly inconsequential; it would not have kept
the Viking lander going by itself.

Where does the shadow come from?  There's nothing close enough to block
sunlight from hitting them.  I wouldn't expect there to be anything block
our view of them either.  What am I missing?

Subject: Space Station Redesign Chief Resigns for Health Reasons
Newsgroups: sci.space

Writer Kathy Sawyer reported in today's Washington Post that Joseph Shea, the
head of the space station redesign has resigned for health reasons.

Shea was hospitalized shortly after his selection in February.  He returned
yesterday to lead the formal presentation to the independent White House panel.
Shea's presentation was rambling and almost inaudible.

Shea's deputy, former astronaut Bryan O'Connor, will take over the effort.

Goldin asserted that the redesign effort is on track.

Right, the Profiting Caste is blessed by God, and may
 freely blare its presence in the evening twilight ..

I posted this over in sci.astro, but it didn't make it here.
Thought you all would like my wonderful pithy commentary :-)

What? You guys have never seen the Goodyear blimp polluting
the daytime and nightime skies?

Actually an oribital sign would only be visible near
sunset and sunrise, I believe.  So pollution at night
would be minimal.

If it pays for space travel, go for it.  Those who don't
like spatial billboards can then head for the pristine
environment of Jupiter's moons :-)
