The title of the lecture is "Space Exploration: The Age of Space Commercialization." Mr. Beggs was Administrator of NASA from 1981-85, during 22 successful shuttle flights. He was responsible for initiating, and obtaining President Reagan's support for, the Space Station program. As the President's representative, he was also responsible for obtaining the cooperation of the European Space Agency, Japan, and Canada for the program. Beggs is currently Chairman of the Board of Spacehab, a company which is involved in building and designing laboratory facilities to be used on shuttle flights. For more information, call PPS President Audrey Robinson at (609) 734-0452. -- Marc W.

Brown, Jr. refers to the book, "Project Solar Sail" and cites the following: "The book also contains a photo of Dr. Robert Forward's Starwisp, a microwave sail ship, on a hanger(?) floor." While glancing through the book, I remember this photo, but didn't read the caption. If it claims that the photo is of Forward's Starwisp design, then an editing error was made. The photo, according to the World Space Foundation in other publications, is of a prototype solar sail designed by the WSF Solar Sail Engineering Mission that was on display at the Paris Air Show four (?) years ago. Forward's Starwisp would not be displayable on a planetary surface; "wisp" is not just an aesthetic term... Ever so often, solar/star sails are brought up in Space Digest. I've probably bored most of the people in the past with private discussions, but I'll take this opportunity to see if there are any new subscribers who are intrigued by this concept...

"The advanced satellites," explained William S. Guion of Goddard's Tracking and Data Relay project office, "will differ from the existing TDRS spacecraft in two important respects: a new frequency band with a high-data rate capability of 650 million bits per second; and an enhanced multiple access system which will increase the data rate provided each of several simultaneous users from the current 50 thousand bits per second to 3 million bits per second." {Existing TDRS satellites are:} TDRS-3 (TDRS-West), 171 deg. W long. (southwest of the Hawaiian Islands and just east of the Gilbert Islands) TDRS-4 (TDRS-East), 41 deg. W long. (off the northeast coast of Brazil) TDRS-1 (TDRS spare), 79 deg. W longitude, near Ecuador TDRS-2 was lost in the Challenger tragedy. NASA AND JAPAN SIGN GEOTAIL AGREEMENT - can900102.txt - 1/14/90 NASA and Japan have completed an agreement for the launch of Japan's GEOTAIL spacecraft on a commercially-supplied Delta II launch vehicle, from the Kennedy Space Center, in July l992. The GEOTAIL spacecraft is a bilateral cooperative mission between NASA and ISAS {Japanese space science agency--SW} which will investigate the stored energy in the geomagnetic tail of the Earth. GEOTAIL will use a double lunar-swingby orbit to take measurements in the region from 8 to 220 Earth radii (Re). ----------------- 4 ARTICLES BY TITLE ONLY--------------------------- NASA RESEARCH ANNOUNCEMENT (Research in Planetary Materials and Geochemistry) - can900103.txt - 1/15/90 NASA RESEARCH ANNOUNCEMENT (Applied Information Systems Research) - can900104.txt - 1/14/90 MAGELLAN STATUS REPORT - can900105.txt - 1/14/90 GALILEO STATUS - can900106.txt - 1/16/90 ------------------END OF CONDENSED CANOPUS--------------------------- This posting represents my own condensation of CANOPUS.

They burn Diesel oil; mileage is something like 30 ft per gallon. From the Spacelink portion of the SPACE archive: 6.2.3.17.3.14 The following document was updated on 12-30-88 and contains 3080 characters. CRAWLER-TRANSPORTER. Tracked crawler-transporter vehicles move the space shuttle vehicles between the Vehicle Assembly Building and Launch Complex 39-A or 39-B. The two transporters are 131 feet long and 114 feet wide. They move on four double-tracked crawlers, each 10 feet high and 41 feet long. Each shoe on the crawler track weighs 2,000 pounds. The transporter's maximum speed unloaded is 2 mph; loaded, it is 1 mph. Unloaded, it weighs 6 million pounds. The transporters have a leveling system designed to keep the top of the space shuttle vehicle vertical within plus or minus 10 minutes of arc-about the dimensions of a basketball. This system also provides the leveling operations required to negotiate the 5-percent ramp leading to the launch pads and to keep the load level when it is raised and lowered on pedestals at the pad and in the Vehicle Assembly Building. The overall height of the transporter is 20 feet, from ground level to the top deck, on which the mobile launcher platform is mated for transportation. The deck is flat and about the size of a baseball diamond (90 feet square). Each transporter is powered by two 2,750-horsepower diesel engines. The engines drive four 1,000-kilowatt generators that provide electrical power to 16 traction motors. Through gears, the traction motors turn the four double-tracked crawlers spaced 90 feet apart at each corner of the transporter. North of the Orbiter Processing Facility is a weather-protected crawler-transporter maintenance facility in which components of the crawler-transporters can be repaired or modified. It includes a high bay with an overhead crane for lifting heavy components and a low bay for shops, parts storage and offices. A pit has been built outside on the crawlerway to accommodate track segment removal and installation. The crawler-transporters move on a roadway 130 feet wide, almost as broad as an eight-lane turnpike. The crawlerway from the VAB to the launch pads consists of two 40-foot-wide lanes separated by a 50-foot-wide median strip. The distance from the Vehicle Assembly Building to Launch Complex 39-A is 3.4 miles and 4.2 miles to Launch Complex 39-B. The roadway is built in three layers with an average depth of 7 feet. The top surface is river gravel. The gravel is 8 inches thick on curves and 4 inches on straightaway sections. When the space shuttle vehicle is fully assembled and checked out in the VAB, the crawler-transporter is driven into position beneath the mobile launcher platform. The transporter jacks the mobile launcher off its pedestals, and the rollout to the launch pad begins. It takes approximately five hours for the unusual transport vehicle to make the trip from the VAB to the launch pad. During the transfer, engineers and technicians aboard the crawler, assisted by ground crews, operate and monitor systems while drivers steer the vehicle towards its destination. After the mobile launcher platform is ''hard down'' on the launch pad pedestals, the crawler is backed down the ramp and returned to its parking area. ------------------------------ Date: 1 May 90 15:37:00 GMT From: ogicse!dali!uakari.primate.wisc.edu!samsung!cs.utexas.edu!news-server.csri.toronto.edu!utgpu!utzoo!henry@ucsd.edu (Henry Spencer) Subject: Re: Sex in space In article <1990May1.024038.1555@larry.mcrcim.mcgill.edu> fdg@sol.UUCP (Frank P.

I think the crawlers are powered by Cummins diesel engines, I don't know what model, but I can probably find out. -ingo /* Ingo Cyliax ECN, Electrical Engineering Bldg. * * cyliax@ecn.purdue.edu Purdue University, W.
