Eligibility: Everyone. Permanent exhibit halls; special exhibits, planetarium and giant screen separate. Skipping the ticket window here saves $25 adult per adult.
Worth knowing: Third-party listicles still claim a Thursday free window — HMNS's own hours page says the free window is Tuesday 5–8pm. Trust the museum's page, not the roundups.
Another way in free: Houston Museum of Natural Science participates in Bank of America's Museums on Us — cardholders get free general admission on the first full weekend of every month.
