Taking aim, preparing for landing
Orbiting craft keeps a weather eye on next Mars mission landing spot.
The prominent circular structure in this image – taken by NASA’s Mars Reconnaissance Orbiter – has been called Jezero Crater. It is the chosen landing site of the Mars 2020 mission, and as such a focus of frequent observation from above.
The image has been artificially coloured by NASA staff, but those colours correspond to different types of sediments – notably, clays and carbonates – carried through channels carved billions of years ago when Mars boasted plenty of water.
