You've probably never seen a wooden arrow explode when someone attempts to fire it from a compound bow. Even a 45# compound bow has the ability to shread wooden arrows (usually doing some damage to the arms of the bowman.) Arrows used in high pull bows are usually hollow aluminum shafts. /\ korpela@ssl.berkeley.edu Internet /__\ rioch BKYAST::KORPELA 42215::KORPELA DecNet / \ of Chaos korpela%bkyast@ucbjade Bitnet (_____________________ ------------------------------ Date: 22 Mar 91 01:05:27 GMT From: swrinde!elroy.jpl.nasa.gov!jato!mars.jpl.nasa.gov!baalke@ucsd.edu (Ron Baalke) Subject: Magellan Update - 03/21/91 MAGELLAN STATUS REPORT March 21, 1991 The Magellan spacecraft and its radar system are performing nominally.

All of the communications margins, spacecraft temperatures, and power levels are within the expected range. Magellan is now in its 1268th mapping orbit. The capture rate of data on the Earth is still about 94%, so we have the equivalent of 1190 orbits on the ground. Yesterday, mission controllers completed the uploading of the final files to reload AACS (Attitude and Articulation Control Subsystem) Memory "B". Today, they are in the process of six uplinks, four related to a gyroscope static detection test and two related to configuration of DMS-A (Data Management Subsystem-A) in preparation for the Tape Recorder Test #2, which is part of the current command sequence. Processing of the data into science data products has been running at or ahead of schedule. However, since it takes as long as two weeks to receive the Original Data Record tapes from the DSN (Deep Space Network) stations in Spain and Australia, the production of full resolution image strips is currently about 150 orbits less than the count of orbits on the ground. ___ _____ ___ /_ /| /____/ \ /_ /| Ron Baalke | baalke@mars.jpl.nasa.gov | | | | __ \ /| | | | Jet Propulsion Lab | ___| | | | |__) |/ | | |___ M/S 301-355 | Change is constant. /___| | | | ___/ | |/__ /| Pasadena, CA 91109 | |_____|/ |_|/ |_____|/ | ------------------------------ Date: 20 Mar 91 16:32:25 GMT From: sdd.hp.com!zaphod.mps.ohio-state.edu!rpi!news-server.csri.toronto.edu!utzoo!henry@ucsd.edu (Henry Spencer) Subject: Re: railguns and electro-magnetic launchers In article <1991Mar20.013858.16326@ariel.unm.edu> prentice@triton.unm.edu (John Prentice) writes: >>Nobody's done this with an EM launcher.

While the final contract negotiations probably will not be completed before April, NASA will purchase only the satellite sensor data from OSC on changes in ocean color for five years after the satellite launch. In return, OSC will have until about August 1993 to develop, build and launch the satellite. It is expected that OSC will use its Pegasus launch system to launch a combination package of a Hughes Sea-viewing Wide Field Sensor (SEAWIFS) mated to its PegaStar small satellite bus. The unprocessed real-time data will be used by GSFC as part of the Global Change research as part of NASA's "Mission to Planet Earth". SEAWIFS will measure concentrations of phytoplankton and chlorophyll by measuring changes in the color of the ocean's surface and support assessment of the global carbon cycle. The contract is not expected to cover the entire program cost, but will act as "seed money" to start the program, in expectation that other commercial applications will be found for this data. OSC retains the marketing rights for all data, and will market the raw data to the Navy and other federal agencies, and is planning to market enhanced data products internationally to a variety of commercial users such as shipping firms, commercial fishing operators, ocean oil, gas and ocean-drilling firms, and to environmental monitoring groups. [Commentary: This is a big step for OSC to establish a complete end-to-end small satellite business area. On this program they will develop the sensor, build the satellite, launch it, gather the data, sell the data, process the data, and sell the processed data. Strategically, this was an excellent move. However, there are some risk areas here - their data will be competing with EOS and SPOT in the commercial world, as well as with the MOS (Maritime Observation Satellite) program in Japan. They will be also competing with an active "after market" in the U.S. and abroad specializing in post-processing Landsat or SPOT data for users. The OSC competitive advantage here is that there are not other firms providing this exact type of specialized data for phytoplankton concentration (although there are firms post- processing it out of other satellite data). Since OSC must finance some part of this venture, this may be a drag on OSC's resources for some time. But it also might pay off very handsomely if enough non-NASA customers are found. NASA also should be recognized as providing a very proper stimulus for commercial space firms in this type of contract. This is the first contract of this type. By acting as "anchor tenant" for this venture, NASA gets the data they desire for a low initial cost, while helping a commercial firm expand into the marketplace. NASA has accepted a slightly higher program risk (if OSC can't find commercial markets for the data, will they continue the project?), but is also potentially saving millions of tax-payer dollars.] -- Wales Larrison Internet: Wales.Larrison@ofa123.fidonet.org Compuserve: >internet:Wales.Larrison@ofa123.fidonet.org -------------------------------------------------------------------------- ------------------------------ Date: 23 Mar 91 14:44:36 GMT From: taco!SEWARD%CCVAX1.NCSU.EDU@mcnc.org (Bill Seward) Subject: Penny wise, pound foolish Does it seem to anyone else out there that Congress is doing to Space Station Freedom exactly what they did to the Shuttle? From all reports I've heard, Congressional funding cuts were the cause of a number of problems with the shuttle program, ranging from that dratted booster rocket that is used to loft payloads from LEO to geosync to a well- known problem with the booster rockets (due to inadequate design testing necessitated by reduced funds). IMHO, it may well be time for NASA to say to Congress what I have recently said to my employer--"You gave me task A to perform. Fine, I'll do it. But let me do it right, or don't ask me to do it at all."
