  I've gotten the impression (from AW&ST and other reports) that the
first space station is intended to be a prototype of future space
stations.  Part of this is due to the realization that one space
station cannot perform all the activities that various customers want
to do in space.  For example, some people want a station in
near-equatorial orbit (easier to launch there, access to GEO) while
others want a station in sun-synchronous (earth observation, Landsat
repairs, etc.).  Then you have the manned space station proponents
(man is more flexible than any machine) versus the unmanned proponents
(man is too expensive for automated factories, movement upsets the 0g,
etc.).  All have valid points.

  The design of the first space station is apparently an attempt to
balance what can be funded today versus the largest number of
potential customers which can be attracted to the current design
(sounds familiar).  Once the bugs have been worked out in the first
station, later specialized stations might be built.  If the Skylab and
Saylet (sp.?) stations are any guide, there are going to be a lot of bugs to
work out.  I realize that NASA my be placing all its eggs in one
basket again, but perhaps it's better to work on getting the first one
right before we have various stations around Earth, the Moon, Mars, etc.

  Speaking of new transportation systems such as the "Orient Express,"
wouldn't it be better if the first test flight of this was aimed at a
space station or shuttle (with a repair crew on board) instead of just out into
space?  I remember crossing my fingers when the first flight of
Columbia showed missing tiles.  The Air Force gets to test new planes
at Edwards, where those huge runways can accomodate all kinds of
errors or breakdowns.  Since the "Orient Express" is bound to have
teething problems, an in-orbit capability to repair the ship (or at
least rescue the crew) would be nice.  It would be one more "huge
runway" to land on.

  I'm surprised the US and USSR don't have a treaty that would
encourage an observation/rescue capability for the first few flights
of new spacecraft.  The Russians hope to try out their new shuttles by
the end of the decade, and NASA hopes to get going on the "spaceplane"
and its own space station.  Add in the "Hermes" and things start to
get crowded!  While there are some security concerns since most of
these spacecraft can carry military payloads, I think the risks of
allowing people a close look (which is available anyway) offset the
dangers to everybody's programs if more crews are lost.  People seemed
to have recovered from the quick death of the Challenger and its crew,
I wonder how people, Congress and the media would react to a stranded crew
(from any country) which slowly suffocated?

The manned space station will only be part of the activity.  There
are also plans to launch `free flyers' from the station into different
orbits that can be retrieved later.  This solves some of the problems
with crystal growth (massive astronauts causing vibrations in the shuttle
or station) and provides isolation for dangerous experiments.  A totally
separate manned station in another orbit may be unnecessary.
