Here is a photograph of the XRS ADR, in the same orientation as the cutaway drawing.

There are a few differences between the ADR as shown in the photo and the ADR as shown in the cutaway drawing.

• In the photo, the structural support cylinder around the salt pill has been removed.
• In the photo, the heat switch is concealed behind structural parts.
• In the photo, the calorimeter location is concealed inside the calorimeter housing (also referred to as the Front End Assembly Housing, or FEA Housing.)
