ExoMars Hardware

Aberystwyth University are manufacturing items of hardware for the ExoMars 2020 rover optical remote sensing instruments – PanCam, ISEM and CLUPI.

Aberystwyth manufactured hardware includes:

PanCam and ISEM Calibration Target – PCT

The PanCam and ISEM calibration target is the reflectance reference standard for the PanCam and ISEM 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 ISEM.

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 acheived – 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.

CLUPI Calibration Target – CCT

The CLUPI Calibration Target provides the reflectance reference standard for the CLUPI instrument. The materials and construction are the same as the PCT but the CCT is considerably smaller – 25 x 25 x 10mm with a mass of 4.5g.
