For ALL Members

ASTC Travel Passport Program (PDF)

You must have the NEW membership card with the ASTC logo on it. (All existing members must exchange your current membership card for the new one. Please bring your old card to the Long Island Explorium and you will receive your new Membership card with logo)

BEFORE YOU GO - check that the museum that you are visiting is participating in the passport program. Check that is is more than 90 miles from the Explorium.
*This distance is measured “as the crow flies,” meaning that it is based on the
linear radius, not driving distance.

Online radius tools can be helpful when determining if a Passport venue is within a 90-mile radius of the Explorium.  Go to
This tool allows you to draw two circles in different colors.  Enter the address of the museum where you are a member first (or their home address, if the museum they wish to visit checks IDs).  Then, enter the address of the museum you wish to visit and create a new circle in a different color.
