Experimental samples bonded to the wheels of the Rashid rover. These wheel-based samples are the platform for the mission’s Material Adhesion and Abrasion Detection experiment – an international extension to the mission’s scientific footprint. The Centre for Research and Engineering in Space Technologies of the Université libre de Bruxelles in Belgium contributed samples while also coordinating the sourcing of others from the Cambridge Graphene Centre of Cambridge University in the UK, York University in Canada, along with ESA. Additional wheel panels were contributed by other science partners around the globe.
