The view of oddly sculpted ground inside the giant Hellas Basin on Mars comes from the High Resolution Imaging Science Instrument on NASA's Mars Reconnaissance Orbiter.
Minerals in northern Mars craters seen by two orbiters suggest that a phase in Mars' early history with conditions favorable to life occurred globally, not just in the south.
Six hundred recent observations of the Mars landscape from an orbiting telescopic camera include scenes of sinuous gullies, geometrical ridges and steep cliffs.
