The name of the post office became Overbrook.[3] In 1877, the Pittsburgh, New Castle and Lake Erie Railroad was constructed through Overbrook, and had a station built there.

Some say it was Parks's wife who enjoyed astronomy, while others believe it was shortened after Samuel Marshall's name.[4] On March 6, 1895, Mars was incorporated as a borough.

In 1904, the Pittsburgh and Butler Street Railway gained permission from Mars to construct its right-of-way through the borough. The line become part of the Pittsburgh, Harmony, Butler and New Castle Railway in 1917, being renamed Pittsburgh, Mars and Butler Railway. The line closed in 1931.

The USS Mars (AFS-1) was named after the borough. The ship became part of the United States Pacific Fleet in 1963, and was decommissioned in 1998. It was then sunk in 2006 as a target vessel. The bell of the USS Mars was loaned to the borough and has become a part of a memorial in the downtown park.
