                 DAILY ACTIVITIES STATUS REPORT
                            FROM THE
      KENNEDY SPACE CENTER/CAPE CANAVERAL AIR FORCE STATION

                      Launch Minus 18 Days

Date of report:     9-7-92         Time of report:     3:00 PM EDT

          [There were no reports on 9-5-92 and 9-6-92.]

The environmental recording equipment was removed from the payload
fairing late Friday night after air conditioning was established.
The data indicate that the highest temperature reached was 79 F,
which is within the specified range.  However, the relative
humidity reached 59% (the specification is less than 55%).  At this
time, there is no evidence of water inside the payload fairing.  We
are assessing the higher than spec humidity and the humidity
profile which occurred during the thunderstorms while the stack was
being prepared for hoisting.

A particle count was taken from an area near the MOLA (Mars Observer
Laser Altimeter) on Saturday morning as part of our continuing
contamination assessment plan.  It did not show excessive particulate
accumulation after the air conditioning was established.  Another
sample was taken Sunday morning and will be analyzed on Tuesday.
Subsequent samples will be taken every 48 hours.

The discharge portion of the battery reconditioning cycle was
completed on Sunday about mid-day, and the 40 hour charging
activity was begun.  When the batteries are fully charged, the
Titan interface connectors will be mated, and a GO/NO GO SEPET will
be performed.

Titan is trouble shooting a failure monitor problem which occurred
today, and have put their subsequent testing on hold.

The schedule of reviews between now and launch have been revised to
include an additional meeting of the Contamination Incident Red
Team.  The Spacecraft Launch Readiness has been reduced to one day.
