Yee) Subject: BBXRT Status for 12/08/90 [1200 CST] (Forwarded) BBXRT Status Report 7 12 p.m. CST, Dec. 8, 1990 Space Mission Operations Control Center Marshall Space Flight Center Huntsville, AL Last night BBXRT obtained seven of the nine targets scheduled. "The best shift we've had so far," reported Dr. Frank Marshall of Goddard Space Flight Center, co-investigator. One of the most interesting targets was MGC 1399, a large elliptical galaxy. BBXRT obtained the first high quality spectrum of the halo of hot gas that surrounds this galaxy. "Much of the gas may be left over from the original formation of the galaxy," Marshall said. Marshall and Dr. Peter Serlemitsos, principal investigator, termed this observation the most exciting to date and are planning to go back to the target for a second observation. This BBXRT observation will enable scientists to estimate the total mass of the cluster, the chemical abundances and deduce the amount of "dark" matter. The BBXRT which was developed at GSFC is being controlled from Goddard's Payload Operations Control Center. ------------------------------ Date: 9 Dec 90 21:02:54 GMT From: rex!wuarchive!zaphod.mps.ohio-state.edu!ub!acsu.buffalo.edu@ames.arc.nasa.gov (marc g boffardi) Subject: Re: Translunar/interplanetary shuttle?

So then, what would be the size of it? Could you fit it in the pay- load section of a shuttle? Would it be advantageous to do that? Have a shuttle inside of a shuttle? Could it be assembled from parts carried IN the payload section of the shuttle or could it be assembled and/or de-assembled at Freedom (whenever THAT gets going...)?

Operations tkelso@blackbird.afit.af.mil Air Force Institute of Technology ------------------------------ Date: 11 Dec 90 04:32:29 GMT From: usc!elroy.jpl.nasa.gov!jato!mars.jpl.nasa.gov!baalke@apple.com (Ron Baalke) Subject: Magellan Update - 12/06/90 MAGELLAN STATUS REPORT December 6, 1990 The Magellan spacecraft is presently performing nominally. Six of the seven STARCALS (star calibrations) of the past 24 hours were successful with attitude updates averaging about 0.02 degrees. No commands were sent to the spacecraft during the past 24 hours. The weekly "tweak" of radar parameters files is scheduled for tomorrow. The radar sensor is operating normally. The Radar System Engineering Team is continuing to analyze the performance of the on-board tape recorders. Yesterday, a telephone conference on the tape recorder A bit error problem was conducted with engineers at Martin Marietta and Odetics, manufacturer of the tape recorder. Odetics currently believes the most likely cause is skew of the record and/or playback heads. They are just beginning to analyze the telemetry data in conjunction with JPL and MMC, and will develop a test plan for tests which can be conducted on the spacecraft as well as a spare tape recorder here on earth. The next meeting will be held at JPL on Thursday, December 13. ___ _____ ___ /_ /| /____/ \ /_ /| | | | | __ \ /| | | | Ron Baalke | baalke@mars.jpl.nasa.gov ___| | | | |__) |/ | | |___ Jet Propulsion Lab | baalke@jems.jpl.nasa.gov /___| | | | ___/ | |/__ /| M/S 301-355 | |_____|/ |_|/ |_____|/ Pasadena, CA 91109 | ------------------------------ End of SPACE Digest V12 #654 *******************
