                            GALILEO STATUS REPORT
                               January 22, 1993

     The Galileo Spacecraft is operating normally in the dual-spin mode and
is transmitting coded telemetry at 1200 bps (bits/second).

     Yesterday, AACS (Attitude and Articultion Control Subsystem)
calibrations were performed, as planned.  Tracking was scheduled over DSS-14
(Goldstone 70 meter antenna) and DSS-43 (Canberra 70 meter antenna).

     Today, January 22, 1993, real-time commands were sent to power cycle the
UVS (Ultraviolet Spectrometer) on/off to exercise the drive mechanism.
Real-time commands are also scheduled to perform planned system fault
protection updates.  Stored sequence planned cruise science MROs (Memory
Readouts) were completed as scheduled.  Also, the planned USO (Ultra Stable
Oscillator) test was performed.  The PWS (Plasma Wave) instrument is also
scheduled to be turned on from the stored sequence.  Tracking is scheduled
over DSS-43.

     Over the weekend, no spacecraft activity or tracking is scheduled.
The AACS inflight mode is scheduled to begin on Monday, January 25, 1993.

As far as I know, boeing doesn't really care WHAT you do with one of their
planes once you buy it (as long as you stay within the operational parameters).

To this end, "what the markets are" really means people lined up cash in hand
to buy one or two of these things.  

Boeing does study the airplane market, and it hurts when an airline goes under,
but they are not in the operations business.  This means that someone somewhere
needs to make an order for one or two of these birds.  Those are the people
that need to know "what the markets are".

This seems to be true of all of the people who are "willing" to build an SSTO.

My question is more on the order of "how do we convince the manufacturers that
they will be able to sell these things?"  Including the possibility that 
somehow WE as a group step up, and place an order.

I checked my notes again, and the notes give the start engines, then flip
sequence.  It is possible that I misheard the speaker (Gaubatz from McDonnell
Douglas).  I expect the most likely explanation is that I have
mis-interpreted the sequence.  An alternate possibility is that the "engines"
started are the RCS thrusters, which run on gaseous hydrogen and gaseous
oxygen.

  Your first idea would be good on an arctic expedition, or
even on a lunar traverse, but not on a trip to Mars, since
everything bewteen here and there ALSO has to be revolving
around the Sun: different distances from the Sun = different
periods of revolution. You could drop stuff off evenly spaced
between here and Mars, but when you got to that distance, they
would no longer be lined up, having travelled along their
orbital paths since they were left.
  The second idea of sending some sort of resupply craft ahead,
and parking it in Martian orbit where you could find it,
redezvous with it, dock and transfer from it, is a MUCH better
suggestion!

I seem to remember that the novel mentioned the use of a "Sakharov
Drive" - it sounded like a pulsed-fusion engine to me... I also
remember them mentioning propellant. I'm not sure if it was in
reference to their own engines or the ones on the Chinese ship Tsien,
who used Europa as a re-fueling point to gather water as extra
propellant.

Organization: Abo Akademi University, Finland

X-News-Reader: VMS NEWS 1.24

I recently saw a couple of pictures of the proposed Thousand Astronomical Units
probe in a book by Nicholas Booth. The craft itself looks like an enlargened
Cassini/Mariner mk.II, with a huge antenna dish [diameter of approx. 15 
meters], an optical laser system for communications, an 1.5-meter telescope 
for carrying out measurements of radial velocities for nearby stars(?) and the 
customary particle and fields experiments equipment.
---
The second part, the ion engine, wasn't really dealt with in the text so I'd
appreaciate it someone could fill in the details. It's basically a long
cylinder with a small nuclear reactor in the rear end powering the engine. The
ion drive will accelerate the propellant [metals like Mercury or Cesium?] to
velocities of up to 70km/s and will fire continuously for ten years. After
that, the two parts would separate and the engine section would act as a relay
station between the probe itself and Earth. The spacecraft will reach  a
velocity of 100 km/s and a distance of 1000 AU (0.002 light-years)
in only fifty years. In addition, a Pluto orbiter could be released as the
probe leaves the solar system.
---
How would the probe be launched? It appears to be far too big and heavy to fit
inside a standard rocket booster. Will they use the shuttle for this, and will
the ion engine be used for accelerating the probe out of Earth orbit as well?
---
Jet Propulsion Laboratory came up with the mission plan. Perhaps Ron Baalke can
shed some light on this?

Grumman's bid was declared ineligible because it was not technically

Oh?  Really?  I could have sworn I saw an ad in this morning's

I understand that they have a system where air is recirculated through
a large mass of soil.  This replicates one of the mechanisms of the
natural biosphere for cleansing the atmosphere.  Microorganisms are
significant sinks for CO, H2, and numerous other trace gases.  And,
indeed, they claim that odors have not been a problem.

I have read, however, that the Shuttle is pretty rank at the end of a
flight.  Is this true?

Where were you?  I was in grade school, and it was raining so we were inside
for our lunchtime recess.  The teachers let us watch the launch live (My 
teacher was a teacher-in-space candidate.)  We spent the whole afternoon
trying to figure out what happened, and the flag was lowered to half-staff
that day and for the following week.  I can't believe they wouldn't let you
discuss one of the most tragic events in recent history.
