− | <p>Viewing the limb of the Moon always increases hope, perhaps because as the surface curves away the perspective changes and there are expectations of seeing something new. Alan’s view of landscapes north of Mare Frigoris was obtained when the libration was unfavorable for seeing to the north pole but it provides a near profile perspective of relatively fresh impact craters. The twin-peaked crater just right of center is [http://www.lpod.org/?m=20060304 Philolaus], with shallow and flat-floored Anaximenes just beyond it to the left. Further left is Carpenter, which is close enough to the limb, and deep enough, that we see only its northern wall and not a hint of its two kilometer-high [http://www.lpod.org/coppermine/displayimage.php?album=3&pos=5 central peaks]. The oblique perspective shows how triffling is the rise of the rims of Carpenter and Anaximenes above their surroundings; typically rim heights are only 1/3rd to 1/4th crater depths. Between Frigoris and the Carpenter region is a relatively flat and bland area that appears to be an unusually smooth deposit of Imbrium basin ejecta. Compared to the highly textured ejecta behind the Apennines, this more distant impact debris is very fine, similar to the fill further east in [http://www.lpod.org/index.php?s=bond Meton and W. Bond]. </p> | + | <p>Viewing the limb of the Moon always increases hope, perhaps because as the surface curves away the perspective changes and there are expectations of seeing something new.
