Maidstone (Mars)

Named after the Town in England.

Maidstone is the county town of Kent, England, 32 miles south-east of London. The River Medway runs through the centre of the town, linking it with Rochester and the Thames Estuary. Historically, the river was a source and route for much of the town's trade as the centre of the agricultural county of Kent, known as the Garden of England. There is evidence of a settlement in the area dating back to beyond the Stone Age. (wikipedia entry)

A crater is a circular depression likely created by an impact event. On Mars large craters are named after deceased scientists, writers and others who have contributed to the lore of Mars. Small creaters (less than 60km) are named after small towns and villages.
