Three Ma'at pits
Filed under Rosetta and Philae, pretty pictures, comets, comet Churyumov-Gerasimenko
Pits Ma’at 1, 2 and 3 on Comet 67P/Churyumov–Gerasimenko show differences in appearance that may reflect their history of activity. While pits 1 and 2 are active, no activity has been observed from pit 3. The young, active pits are particularly steep-sided, whereas pits without any observed activity are shallower and seem to be filled with dust. Middle-aged pits tend to exhibit boulders on their floors from mass-wasting of the sides. The image was taken with the OSIRIS narrow-angle camera from a distance of 28 km from the comet surface on September 12, 2014. From left to right the pits measure 125 m, 130 m and 140 m across and are 65 m, 60 m and 50 m deep, respectively.
