Subject: LNLL Inflatable Stations
Sender: [e-mail]
To: [e-mail]

I like LNLL's approach to a space station - inflatable modules, but I
keep wondering:

Sure, the module's themselves won't weigh much, and will be easy to
launch, but how do you equip them? Is the eqipment installed after
inflation or before? On Freedom, everything is simply installed
inside the modules before launch.

Another question, on all of the artists conceptions I've seen of the
LNLL station, there are no windows. Are any planned? Freedom
won't have many windows, but it does have the observation node
which should give a spectacular 180 degree view. A lot of doctors
have said this is important to relieve the clausterphobic effects
of living in a small place.

One thing I did like about LNLL was the ability to spin the station
if wanted for artificial gravity. This will be great to keep the
astronauts physically fit, but won't the Coriolis effects, even for
light gravity be pronounced on such a small station?

I like LNLL's idea, but I haven't heard anything about this stuff.

Funny, I started this posting with only one question...

Hi - Just a quickie -

does anyone out there know anything about the International Space University ?

A friend mentioned it to me, but he's gone postgradding elsewhere now, and
I can't get in touch with him to get the info again...

any help gratefully received.

The program will have enough money next year to fund ~7 people. I assume
they will continue design work on the modules. At the grassroots, we
need to have people write and meet with their representatives. If any of
your representative sits on the Energy and Water Development subcommittee
of the Appropriations committee this is expecially important. If you
don't know your representatives comittee, write me and I'll let you know.
In addition, letters to NASA and the Space Council would help.

The single biggest thing holding the Great Exploration up is turf
battles with NASA.

Nonsense.  There are many Earthly environments that are far more hostile
than open space, because they are much less predictable and much less
controllable.  Space is actually quite a benign environment, given proper
preparations.  (Well, low Earth orbit is getting a bit unpleasant due to
the space-debris problem, but other than that, the statement holds.)

The hostility of open space is much overrated, or rather, the raw hostility
of Earth environments is much underrated.  Six-year-old Saskatchewan kids
routinely walk to school unaccompanied in an environment that would kill
an unprotected human almost as quickly as open space would.  I recall an
incident in high school when I went out the door into a brisk wind at maybe
-20 or so, dropped some papers, hastily shed my clumsy mittens to pick the
papers up before they blew away... and then headed back indoors at a dead
run, because after less than thirty seconds of exposure, I couldn't feel
anything below my wrists.  No actual injury, as it turned out, but
thoroughly terrifying.  Few people appreciate just how deadly our "normal"
environment can be if we let our guard down.

As witness the spectacular failures of aerospace-company ventures into
things like mass transit in the early 1970s, not so.  The basic technologies
are applicable, yes, but as Allen points out, the *tradeoffs* are completely
different.  Boeing had the knowledge to build a workable airliner, yes, but
that is very different from building a *successful* one.  If the 707 had had
the maintenance requirements and operating costs of most then-current
military systems, it would have been a commercial disaster despite technical
success.  In fact, the airlines were braced for trouble, and vastly overspent
on things like spare parts.

>...Getaway Special on a shuttle or on a sub-orbital launch is different from

Quite true.  Of course, by this standard, most of the NASA centers involved
in the space station are incompetent for the job too, since only one (MSFC)
has ever built anything like this before.  (JSC arguably might qualify due
to the shuttle orbiter, but launchers and space stations are very different.)

                       MONDAY NOVEMBER 5, 1990

SpaceNews originates at KD2BD in Wall Township, New Jersey, United States.
It is published every week and is made available for unlimited distribution.



* PIONEER 11 STATUS *
=====================
The Pioneer 11 spacecraft emergency support continues with 70 meter antennas
in high power transmitter uplink configuration.  Non-coherent downlink
telemetry has been processed by the Ames Research Center.  Following the
uplink with the 70 meter antenna in Spain on 28-Oct-90, the 70 meter antenna
in Goldstone was unable to acquire 3 way downlink.  The project at Ames
reports commands are getting into the Pioneer 11 spacecraft, but the planned
receiver swap was not successful.

[Information via JPL]


* MAIL BAG *
============
I've been receiving quite a few questions recently about DOVE-1/OSCAR-17.
First of all, DOVE transmits on a frequency of 145.825 MHz FM.  This
downlink carries spacecraft telemetry (AX.25 AFSK packet radio format)
as well as synthesized voice transmissions.  To date only telemetry has
been carried on DOVE's downlink as spacecraft testing continues.
After new software has been loaded and tested on DOVE, the Votrax speech
messages should be heard.  It should also be mentioned that DOVE-1 does
not have mailbox capabilities.  It was designed primarily for downlinking
digitized voice messages to Earth.

Q: Could you carry Keplerian orbital data in SpaceNews?
A: Since there are other outlets for Keplerian orbital data, I would rather
   not repeat that information here. (Sorry!)

Q: Are they any satellites that I can access with an HT?
A: Well, you could get a signal into RS10 or RS11 on Mode A with nothing
   more than a handheld 2-meter transceiver if you were to key the PTT
   button with CW, but this usually results in a very chirpy signal!
   FM and other "constant carrier" emissions should be avoided when
   communicating through amateur satellite transponders.

Q: Is "SpaceNews" associated with the trade journal "Space News"?
A: No.  "SpaceNews" has been in existance since November 1987.
   It is dedicated to topics of interest to Amateur Radio operators
   worldwide and is non-profit publication without connection to any
   organization, public or private.


* OSCAR-13 NEWS *
=================
Command Stations performed magnetorquing procedures near perigee of orbits on
October 15-17.  The new transponder schedule is as follows:

Mode-B : MA 000 to 095
Mode-JL: MA 095 to 125
Mode-LS: MA 125 to 130
Mode-S : MA 130 to 135
Mode-BS: MA 135 to 140
Mode-B : MA 140 to 256
Omnis  : MA 220 to 040

This schedule is expected to continue throu 26-Dec-90.  The spacecraft
attitude is BLON = 180  and  BLAT = 0.

This must have occured to someone before but...

If the shuttle has to abort its launch and land
on the other side of the Atlantic, does it qualify for
the Trans-Atlantic speed record?

Similarly, if it were to abort a bit later and land
back in the US, if it were to land back a KSC (it doesn't,
it lands at Edwards AFB, but this is hypothetical) would
it count for a round the world record? or maybe the second
craft to fly around the world non-stop?

I suspect that a short venture into space is what would disqualify
such a flight.

On a more technical note, does the shuttle need to fire the OMS
rockets to get down from such a abort cleanly? Does the shuttle
undergo the rigours of a normal reentry? I guess the answers are
no, and yes, but I'm curious.
