Which instrument's detailed imaging analysis has occasionally failed to corroborate expected geological signatures of ancient shorelines in targeted areas?
Answer
HiRISE camera
Images from the HiRISE camera onboard the Mars Reconnaissance Orbiter have sometimes failed to show the definitive sedimentary sequences expected if a large ocean had existed.
