|Stereo Panoramic Imager (SPI)
||Stereo color cameras on a pan/tilt unit.Returns panoramas and high-res images up to 1
mm/pixel resolution. Primary sensor for target selection and understanding science context.
||High. Integrated with rover. Returned useful science data. Minor calibration, reliability
|Visible/Near Infrared Spectrometer (VNS)
||Returns spectra in visible and near-infrared wavelengths. Primarily used for mineralogy,
may also detect chlorophyll
||Medium. Backpackable unit separate from rover. Returned useful science data. Mature
|Fluorescence Imager (FI)
||Returns visible reference and fluorescence images. Used to identify life by detecting
naturally fluorescent biomolecules such as chlorophyll.
||Low. Integrated with rover. Did not return useful science data. Basic technology research
|Environmental Sensors (ES)
||Weather station with wind, humidity, insolation sensors. Used for both engineering
(e.g., solar panel performance) and science environment understanding.
||High. Stationary weather station separate from rover. Returned useful data. May or may not
be integrated with rover in future expeditions; integration not expected to be challenging.
