The ASTC Travel Passport Program offers free general admission to over 350 science centers and museums worldwide for members of participating institutions. For 2026, ASTC implemented a standardized minimum membership cost to qualify, excluding memberships priced under $100.
The 90-Mile Rule: Free admission is only valid if the science center or museum you are visiting is more than 90 miles "as the crow flies" away from both your home residence and the specific museum where you hold your membership.
New Membership Cost Threshold: Starting in 2026, ASTC standardized guidelines will remove reciprocal passport benefits for most museum memberships priced under $100.Admission
Limits: Standard reciprocal admission covers general exhibits for up to two adults and four children (or as defined by your specific home membership tier).
Exclusions: Special ticketed exhibits, planetariums, giant-screen/IMAX theaters, and parking fees are not included.
What to Bring When Visiting:
What is the National Museum of Nuclear Science & History's reciprocal admission policy?
The museum offers free admission for 2 adults and up to 4 children with a qualifying Association of Science-Technology Centers (ASTC) reciprocal membership. Your home museum membership card must have the ASTC logo.
We cannot verify reciprocal museum memberships. Reciprocal visitors must present current membership cards and photo ID when checking in at our admission desk. Reciprocal admission includes the museum's standard exhibits. This does not include any upcharge traveling exhibitions or the Museum Artifact Center (MAC). These additional experiences are available for purchase upon checking in.
