As of 2007[update] seven putative cave entrances have been identified in satellite imagery of the planet Mars, all so far located on the flanks of Arsia Mons.[53] A more recent photograph of one of the features shows sunlight illuminating a side wall, suggesting that it may simply be a vertical pit rather than an entrance to a larger underground space.[54]
