The ‘Small Items’

Aberystwyth University are manufacturing three items of hardware for two of the ExoMars rover optical remote sensing instruments – PanCam and Enfys. They are known collectively as the “PanCam Small Items”:

PanCam Calibration Target – PCT

The PCT is the reflectance reference standard for the PanCam and Enfys instruments. The colour patches are manufactured from coloured glass and the structure from aluminium. The PCT has dimensions of 67 x 76 x 18mm and a mass of 40g. The 6 small colour patches are for use only by PanCam, the two larger patches are for use by PanCam and Enfys.

PanCam Fiducial Markers – FidMs

The Fiducial Markers provide geometric reference points on the top deck of the ExoMars rover. These will be used to confirm that the mast has unfolded correctly from its stowed configuration on the Martian surface. The 3 FidMs have dimensions of 32 x 16 x 6.5mm and a mass of 1.2g each.

Rover Inspection Mirror – RIM

The Rover Inspection Mirror is a convex spherical mirror mounted on the rovers front left bogie suspension bracket. When imaged by the PanCam High Resolution Camera, the RIM will provide views which cannot otherwise be achieved – including the underside of the rover and the end of the drill. The RIM is 50mm diameter and together with its mounting bracket has a mass of 20g.
