RELEASE: 90-42
GODDARD TROPHY CEREMONY PLANNED AT WHITE HOUSE
Vice President Dan Quayle, in a special White House ceremony
on March 19, will make a special presentation of the Dr. Robert
H. Goddard Memorial Trophy to the 1990 winner Dr. Lew Allen,
Director of the NASA Jet Propulsion Laboratory, Pasadena, Calif.,
and Vice President of the California Institute of Technology.
Dr. Allen received the 1990 award "For distinguished and
significant contributions to the Nation's advancement in space,
earlier by service with the Air Force and the strategic defense
of the country, and currently by leadership with NASA in the
assurance of United States preeminence in planetary exploration."
The Goddard Trophy, premier award of the National Space Club
and the aerospace industry, was established in 1958 and is
presented each year at the Goddard Memorial Dinner. The
recipient of this award is selected annually by the Board of
Governors of the National Space Club.

Subject: Re: The Amazing Flying Coilgun
As a long time fan of LTA vehicles, I *like* the balloon assisted
coilgun launch system. It even can be portable, given a suitable
powersource at the launch site. Let's see NASA, ESA or Glavcosmos (sp?)
deliver door to door service. Hydrogen has a (largely unearned) bad
rep as a lifting gas, and helium is expensive, so I would imagine
hot air is the best lift source. The system even scales up nicely.
If you make the balloon large enough, it can be made out of materials
like steel and still have lift (Power requirements are large at this scale).
If the target markets can't supply an appropriate power supply, the balloon
could use something on-board given the right size (A balloon the same
mass as an aircraft carrier could carry a nuclear reactor, although
getting permission for overflights enroute to markets might be
interesting).
More seriously, balloons will probably be useful for research
on planets like Venus or Titan which have dense atmospheres (I wonder
what the lift strategy is for the cyntherian balloon, since a hot-air
balloon would have to be hotter than the 600 degree atmosphere) and
the gas giants, which have nothing *but* dense atmospheres.
