The shoulder patch of the Mars, Pennsylvania, Police Department.

The patch of the Mars, Pennsylvania, Police Department was adopted in August 2002. Shaped like the Pennsylvania Keystone, the patch depicts the red planet, along with a spaceship. A similar spaceship, measuring 7 by 7 feet and weighing 2,800 pounds, sits in a downtown park. Mars, a borough in central western Pennsylvania, was founded in 1873 and is the only town in the United States with that name.
