| Here are some notes I took at the Boston chapter of the
National Space Society/L5's November meeting.
Professor Ranko Bon spoke at the meeting.
Professor Bon is an architect whose specialty is the rather new
and obscure field known as building economics. He was involved in
what he humorously called the "Building Technology Revolt" in the
MIT architecture school -- this consisted of foreign students who
were not interested in American professors teaching them how to
build Appropriate Technology shelters (i.e. dung huts). They wanted
high-tech. So Professor Bon devised an interdisciplinary design
course, "Space Habitat Design Workshop".
The first course focussed on the design of a space station using
deployable structures -- lightweight framing that could be collapsed
for transport, and easily unfolded in space. The goal was the limiting
of the number of flights and the amount of eva work (it being dangerous,
inefficient and expensive to have people in space suits bolting things
together in zero-g).
Bon showed slides made from CAD diagrams of the structure and details
of the proposed framework. He estimated that three shuttle flights
would have been necessary for a minimum livable station.
The second version of the course, which is currently in progress,
expanded further the multidisciplinary character of the course.
The course featured speakers, and students, from the Aero & Astro,
Mechanical Engineering, Architecture, Civil Engineering, and other
departments. Bon also invited the flamboyant Wendel Wendel (have
I got his name right?), founder of Space Structures International,
a firm specializing in deployable structures. Wendel's motto is,
"Why wait for NASA?" Midway through, the students voted on their
mission: to design a moon base.
Bon then showed slides detailing some of the current thinking in
the course: a network of 3000 meters of tunnels, laid out in
hexagonal grids in the loose rock of the rim of a large crater.
In situ rock melting technology, which has been used on a small
noncommercial scale in Arizona, would be used to form the
tunnels. These tunnels, which would be five meters in diameter,
would then be segmented into pressurized habitation tunnels
thirty meters long. Bon emphasized the importance of dispelling
a "submarine" or cave-shelter ambiance through use of plants,
fiber optic lighting and other features. The base would hold
180 people.
Two-hour presentations on the final design will be given on
December 7th and 9th, starting at 5pm, in building 3-133 at
MIT. Bon invited all interested to attend.
During the talk I scribbled down a few quotes I thought were
interesting.
"Engineers and architects, when put into a friendly environment,
generally cooperate nicely...at first the engineers do not want
to come out of their corners... but you show them some good ideas,
and then they will come out."
"You know it will not all be designed by scientists and engineers.
It will be designed by many people. Dumb ones, crazy ones, all of
us."
"If I gave you $2 million to design a new kind of shoe, what would
you do? You would spend it!"

Upcoming Boston NSS & Other Events.
Most Boston NSS meetings are at 7:30 pm on the first Thursday of each month.
Meetings are in MIT building NE43, 8th floor RplayroomS, 545 Main St.,
Cambridge. Main St. goes from Central Square toward the Longfellow bridge
and Beacon Hill. NE43 is the only 9 story building where Main St. crosses
the railroad tracks, park in the parking lot between the building and the
railroad tracks.
If coming by subway, take Red Line to Kendall Square, walk away from downtown
Boston, first building after the railroad tracks.

Subj: NEWS: Amateur Balloon Launch in Huntsville AL
On 7/31/94, the Huntsville Alabama L-5 Society (a chapter of NSS), and
the Alabama Space and Rocket Center co-sponsored a balloon launch. The
payload, launch, and recovery were supervised by Bill Brown, for whom
this was the 45th launch. Tracking and recovery assistance was
provided by many enthusiastic local hams.
The balloon carried two major payload modules: a VHF HAM repeater
(144.34 MHz), and an amateur TV module. Additionally, a packet of new
membership cards for HAL-5 was flown, duct taped to the top of the VHF
module.
Bill started the day with a presentation to a group of teachers at
International Space Camp, while we awaited the predicted breakup of a
cloud cover.
A picture-perfect launch was achieved at 9:55 am Central time, from
the lawn next to the Apollo 11 lunar crater mockup at the Space and
Rocket Center. The balloon reached an estimated 123,000 feet, at which
point the limb of the Earth was visible through more than half of the
camera's field (I forgot to ask what lens he was using) with space
above it. The balloon burst at 11:58 AM, and continued to transmit
video essentially all the way down. TV reception was reported from
Rolla, MO, Springfield, IL, Melbourne, FL, and many points nearer. The
whole adventure was recorded by WHNT-TV reporter Dick Curtis, himself
a ham and a bit of a space nut. He went to Tennessee with the chase
team and filmed the payload recovery from a cow pasture belonging to a
rather surprised farmer.
We're all ready to do it again anytime Bill has a payload ready.
Usually, he flies a GPS circuit and adds telemetry from that to the
video, but this time the GPS box would just not talk to the TV
transmitter, despite all-night hacking. Also, the VHF repeater froze
up between 40,000 and 80,000 feet, but worked again from 80,000 on up.
Outside of those minor flaws, it was an outstanding flight, and a big
thrill for all concerned.
