SP-424 The Voyage of Mariner 10

 

Fig. A-29. Close inspection of the many individual frames used to make the mosaics of the earlier figures provides a wealth of new information about the innermost planet. The presence of other large basins was confirmed in (a) is shown a flooded 240-km (150 mi) diameter basin, its walls indicated by arrow heads, as revealed at Mercury I Another flooded basin (b) photographed at Mercury II is 350 km (220 mi) in diameter and appears to be flooded with plains material and then subsequently cratered by some large impacts. Not only did the filling material partially inundate small craters which had formed along the rim of the basin at the lower left but also overflowed the rim and spilled onto the surrounding terrain at the top right.
