DS - Dust Sensor

The DS instrument will perform dust measurements in the Mars boundary layer. It is composed of a set of IR detectors, an IR emitter, both working in the MWIR band, and an SMA actuator. During the mission, the instrument acts as an active sensor, and will perform measurements of the dust in suspension, discriminating on scattering/absorption. The function of the actuator is to provide a black body reference to the detector for calibration.
