Data Set Overview
=================
 
This data set presents the temperature measurements of the Stardust
Sample Return Capsule (SRC).  Twelve different sensors were placed at
various locations in the SRC and used to monitor the thermal
environment and the temperature of the individual components of the
instrument.  Temperatures measured by each sensor were recorded,
typically every few minutes, throughout the mission.  The last
measurements were taken shortly before the SRC separated from the main
body of the spacecraft.
 
  SRC Temperature Sensors
  -----------------------
 
    The following temperature sensors were installed inside Stardust
    Sample Return Capsule (SRC).

   Notes: The heater(s) that maintained avionics and battery
   temperature were located on the avionics side of the deck. The
   shoulder and wrist sensor readouts are probably most representative
   of the collector temperature.

Event Timing
------------
 
Below is a list of mission phases and events that could affect the
temperature of the SRC components, and the dates when they occurred
during the mission.
 
DSM events -- Deep space maneuvers, which produce changes in the
              spacecraft orbit
ISP events -- Periods when the SRC is open and the collector is deployed
              to collect samples of interstellar dust particles

SRC Re-entry                  2006 Jan 15
 
SRC separation from the main body of the spacecraft occurred at 05:57
UT on 2006 Jan 15.  The capsule re-entered the Earth's atmosphere at
09:57 UT and landed at 10:10 UT on the same date.

In general, the precision of
       the temperature measurements is approximately 0.2 C, even
       though the entries are given to six decimal places.
