Date Acquired: September 29, 2009
Image Mission Elapsed Time (MET): 162744150
Instrument: Narrow Angle Camera (NAC) of the Mercury Dual Imaging System (MDIS)
Resolution: 0.40 kilometers/pixel (0.25 miles/pixel)
Scale: The basin is approximately 290 kilometers (180 miles) in diameter
Spacecraft Altitude: 15,600 kilometers (9750 miles)
Of Interest: This unnamed impact basin was seen for the first time yesterday during MESSENGER's third flyby of Mercury. The outer diameter of the basin is approximately 290 kilometers (180 miles). This basin has a
double-ring structure common to basins with diameters larger than 200 kilometers (about 125 miles). The floor of the basin consists of smooth plains material. Concentric troughs, formed by surface extension, are visible on the basin floor, similar to
those seen in Raditladi basin. Such troughs are rare on Mercury, and the discovery of such features in this newly imaged basin is of great interest to members of the MESSENGER Science Team. Crater chains produced during ejecta emplacement also can be seen emanating from the basin.
