| Outline of Final Research Achievements |
Current formation rate of craters is an essential information in estimating formational ages of recently geological activities. Because automatic identification of new craters is, at least currently, difficult, we performed “citizen mapping” of craters in a space museum, TeNQ, located the center of Tokyo. More than 30,000 people joined this activity for more than two years. We successfully identified 476 new dark patches within 1.0x10^7km2, which is about 7.06% of the entire Mars. This gives the formational rate of 1.3x10^-5/km2/yr, which is one order of magnitude larger than previous analyses based on image analyses and theoretical impact flux.
