Depuis 2006 la sonde MRO (Mars Reconnaissance Orbiter) de la NASA est en orbite à 300km autour de Mars.
A bord de MRO se trouve la caméra HiRISE de très haute résolution qui prend des photographies de la planète Mars depuis plusieurs années maintenant.
Très belle sélection d'images de HiRISE visibles sur Boston.com.
