Abstract

Tonight we will begin our Moon walk in the lunar north as we explore another challenging region - Sinus Roris (Fig. 11.1). “The Bay of Dew” is actually a northern extension of the vast region of the Oceanus Procellarum. Covering about 202 km, many lunar maps are not quite true to Sinus Roris’ dimensions. Its borders are not exactly clear given the curvature on which we see this feature, but we do know that the eastern edges join Mare Frigoris. This area is much lighter than most features of this type. If you seek answers, then look further north as Roris’ high albedo can be attributed to the ejecta from many nearby impacts. It also holds a fanciful place in history, as seen in this excerpt from the science fiction story “Man on the Moon” by Wernher van Braun.
