The Shuttle is a highly unsuitable vehicle for transportation into deep space or orbital manouvering. This is because it carries a substantial dead-weight penalty in the form of its aerosdynamic wings, stabilizer, fins, control system, and heat shield. For unmanned missions it is also penalized by having a heavy life support system. Better to keep the shuttle for its only halfway economic role, Earth ot LEO. Other missions require different vehicles. -- Charles Radley Internet: Charles.Radley@ofa123.fidonet.org BBS: 714 544-0934 2400/1200/300 ------------------------------ Date: Sun, 15 Jul 90 10:17 CDT From: Subject: UNSUBSCRIBE ME Please unsubscribe me from the space digest. ------------------------------ Date: 14 Jul 90 13:36:16 GMT From: elroy.jpl.nasa.gov!zardoz.cpd.com!dhw68k!ofa123!Charles.Radley@decwrl.dec.com (Charles Radley) Subject: Re: Bush Approves Cape York A Royal Australian Air Force base is planned for Cape York, independent of the Spacecport plan, but will allow "significant economies" according to the Cape York IAE report.

It is part of life. I think the point of the regulation is that with the money invested in training, scheduling etc that these individuals should not *seek* out addititional, high risk activites.

A pretty lousy comparison. A more valid one might be, "Would you buy a car that got 30 miles to the gallon and had a maximum speed of 80 miles per hour (in other words, average) based on the promise that eventually it would achieve 300 mpg and 800 mph." To that, I'd probably answer, "Sure!" -- Disclaimer: All spelling and/or grammar in this document are guaranteed to be correct; any exseptions is the is wurk uv intter-net deemuns,.

The liquid hydrogen tanking test on the Space Shuttle Atlantis at the Kennedy Space Center went smoothly last Friday. Current activities include visual and photographic inspections of the aft compartment. NASA managers are currently reviewing the data from the testing procedures, the photos as well as the purge flow rates to better understand the data collected. Also, preparations begin today for changeout activities on Auxiliary Power Unit #3. ******** Meanwhile, technicians at the Orbiter Processing Facility renewed the liquid argon dewars used to keep the Broad and X-Ray Telescope cooled. This procedure is part of the ongoing maintenance schedule of the Astro-1 payload. The Astro-1 multiple observatory will be launched aboard the Space Shuttle Columbia. The launch date will be determined after the source of the orbiter's hydrogen leak is identified and necessary repairs are made. ******** Also at KSC, preparations are underway to move the Spacelab Life Sciences 1 transfer tunnel to the Cargo Integration Test Stand later this month. This operation will serve as a fit check and the actual installation for flight will occur in the Orbiter Processing Facility. The SLS-1 is also scheduled to fly aboard the Space Shuttle Columbia following the Astro-1 mission. ******** The Hubble Space Telescope Review Board, under the guidance of Jet Propulsion Laboratory Director Dr. Lew Allen, is scheduled to meet July 25 at the Hughes Danbury Plant in Danbury, Connecticut. The facility is the location of the Hubble mirror maker Hughes Danbury Optical Systems, Inc. The Board will review the work history and study ideas for possible future tests. ******** --------------------------------------------------------------- Here's the broadcast schedule for Public Affairs events on NASA Select TV.
