                        MAGELLAN STATUS REPORT
                           November 8, 1990
 
     The Magellan spacecraft is in good health, in its Superior Conjunction
mode.  The daily STARCALS (star calibrations) and twice daily DESATS
(desaturations) have been successful.
 
     Yesterday's commands to re-configure the spacecraft were successfully
uploaded, including setting the command loss timer to 9 days and disabling
the S-band RF loss monitor.
 
     Today the spacecraft controllers plan to play back track 4 of the tape
recorder and uplink other configuration commands in preparation for Friday's
upload of the mapping sequence.  Execution of the sequence will begin with
orbit #787 at 4:07 AM PST on Saturday, November 10.
 
     If mapping resumes as now scheduled, the "Superior Conjunction Gap" will
include 110 orbits or about 22 degrees of longitude.  This area will be mapped
between June 26 and 11 July 11, 1991, when Magellan again passes over.
