The MMSD Planetarium is located in Vel Philliips Memorial High School. The entrance to use for public programs, assuming parking in the large parking lot on the Mineral Point Rd side of the building, is the main entrance (under the awning). There are navigational aids in the hallways but you will take a left, a right, head straight ahead and up a small staircase, and then veer slightly left to enter the commons (by door #3) and the planetarium entrance.
