This list of science centers and museums participating in the ASTC Passport Program is in effect May 1, 2008 - October 31, 2008.

Please note—local restrictions apply
Science centers and museums located within 90 miles of each other are excluded from the program unless that exclusion is lifted by mutual agreement. Restrictions may apply based on residency. See the PDF for details. Each institution has its own admissions policy, so call before you go to get the details. Also, reciprocity extends only to regular admission—it does not include free admission to additional attractions such as planetarium shows, simulator rides or giant-screen films. It also does not usually include museum store discounts.
