Name: Mars Cratering Activity 1 Use the web application shown in the video tutorial For this activity, you will be estimating the age of the Hadriaca Patera region (image 1) in the web appplication.  Count the number of impact craters greater than 500 m in diameter for the square region of 15.42 km by 15.42 km.  Non-impact craters for that square region should not be counted.  Once you know the number of impact craters for that square region, use the following formula to estimate the number of craters per million square kilometers: Show all work:  Image # 1 ( Hadriaca Patera ) Surface Density = 10 6 k m 2 × ( number of impact craters ) ( linear ¿ region ) 2 = ¿ 10 divided by 15.42^2 =0.042056318 x 10^6= 42,056 craters per million Age: 3 billion years

Name: Mars Cratering Activity 2 Use the same web application as before. For this activity, you will be estimating the age of the Nirgal Vallis region (image 5) & the Dao Vallis region (image 9) in the web application.  Count the number of impact craters with different cut-off diameters for the different square regions.  Non-impact craters should not be counted.  Once you know the number of impact craters for that square region use the following formula to estimate the number of craters per million square kilometers: Show all work:  Image # 5 ( Nirgal Vallis ) Surface Density = 10 6 k m 2 × ( number of impact craters ) ( linear ¿ region ) 2 = ¿ 17.39^2= 302.4121 divided by 10^6 x 11 = 100000= 11000000 divided by 302.4121 = 36374.20593 Age: 2 billion years  Image # 9 ( Dao Vallis ) Surface Density = 10 6 k m 2 × ( number of impact craters ) ( linear ¿ region ) 2 = ¿ Age: 11.64^2= 135.4896 10^6 x 8 =8000000 divided by 135.4896 = 58914.67388
