The 'roid in Spain drills mainly on the plain: Plucky Brit Mars robot laps up sun, sand and, er, simulated science

A prototype Mars rover, named Charlie, has gone for a trundle around Spain’s Tabernas Desert this week, as scientists gear up for the real thing in 2021.
The UK-built trundlebot was controlled by the ExoFiT team at the UK’s Harwell Space Cluster in Oxfordshire, 1,000 miles away from the sun and sangria of Spain where the remote controlled rover did its thing.
