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:

Surface Density= 10^6 km^2 x (10)/(15.42)^2 =10,000,000/237.7764 = 42,056.32 =4.2 x 10^4
Age: 4.2 billion years old

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:

If you skip the graphs, you will only earn credit for the Surface/Crater Density questions if you
did them correctly.
There are only three questions, so be careful.
