The BHIS will go into the borehole after the drill is removed in order to remotely sense the charactiristics of the borehole. The BHIS will provide imaging, and collect Raman spectra, and magnetic and conductive properties of the borehole rocks. The BHIS will be deployed nominally no more than once per meter. After the core is retrieved by the Mars analog drill core retrieval system, the walls of the hole are imaged and analyzed with the Bore-Hole Inspection System, (BHIS). The BHIS can position the inspection tool from depths ranging from 0 to 25m with a precision of ~0.1mm. The BHIS consist of two main parts, the Bore-hole Inspection Tool, which positions and takes readings from the mounted cameras and Raman spectrometer; and the Bore-hole Inspection Standard Tool, which analyzes and records data collected in the hole from its magnetic susceptibility meter apparatus. In general, the BHIS' main components are:

-RAMAN Spectrometer (Jovin Ibon): The working wavelength is 633nm, its spectral range is 200-3600 cm -1 and has a spectral resolution of less than 10cm -1 , and it is controlled by a PCI bus CCD controller board. The laser is a Helium-Neon Laser with the fiber coupled with a FC connector. This particular laser has low noise, good beam pointing stability, and long-term amplitude stability.

-Macro and micro imaging cameras: To image the walls of the hole as well as spot analyzed by the RAMAN spectrometer the BHIS uses the M820 cameras (manufactured by JAI). These color cameras have a composite video signal CCD sensor with effective pixels at 752(w) x582 (h), field of View less than 20x20mm, and a resolution better than 0.05mm/pixel.

-Magnetic Susceptibility Meter (manufactured by Geovista): This apparatus has a range from 10 -4 up to 2 SI units and has adjustable gain for measurement in range.
