Investigate Images of Moon Craters, Valleys and Walls
Investigate the craters on any image. Here are some ideas.
See more directions at the end of this page.
Find the center of the crater using the x, y coordinates. Look at the status bar at the bottom of the Image Processor. It tells you the position of your cursor on the image with an x value and a y value. (x,y)
Carefully observe the structure of each crater or other moon feature, such as mountains, valleys or walls. Describe or sketch what you see. Record your ideas and questions.
Something to calculate....
Measure a crater diameter or circumference or a valley length.
Use slice and record the distance in pixels (from the Slice pop up graph) on the Moon images. Help with using the slice tool and calculating pixel scale.
Plato is 62 miles (or 100 kilometers)
across. To find the pixel scale for these images, divide the number of kilometers or miles
by the number of pixels for the crater Plato.
What is the pixel scale in kilometers? _________
What is the pixel scale in miles? _____________
Measure each crater or feature. Multiply the distance in pixels times the pixel scale you calculated above.
