Notes:
(1) The data won’t be played back until the spacecraft is on the High Gain Antenna.
(2) The housekeeping data between collected from the turn on until 023T02:35:00 will not
be played back.
(3) The data from the PIM may be lost because of the short DSN track.
2 ACTIVITY CONSTRAINTS
SSR loading is the main constraint. We have specified 2.2 Mbits in the Masursky CAR.

Under this configuration the data volume is 1.21 Mbits.
The duration of the single integration is 01:37:00. That gives us about 00:02:40 to dump
the data to the SSR before the instrument is shut down. The telemetry mode is expected to
be S&ER3. The buffer should be dumped in about 35 seconds.

5 PLANNED REAL-TIME AND CONTINGENCY COMMANDS
There are no planned real-time commands. All of the Masursky associated activities
occurred “in the blind”.
6 FLIGHT SOFTWARE VERSION AND PATCHES
Flight software version 1.1 will be used, patched for crn 42. The patch will be applied
from the background sequence after the RAM code has been loaded (as implemented for
ICO 1, V2 and ESB).
7 MAPPING OF ACTIVITIES TO DISTRIBUTED SEQUENCES
The latest allocated ODC ID is 31.
