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).
