It is $9 for adults, children 3-12 and seniors over 65 are $7.50. Military and 1st Responders are free. The first Sunday of every month it is free to enter museum but you must pay $6 for unlimited planetarium shows on that day.
No. It's not free. I paid $7.99 entry fee bc I was with a group. I think the normal fee is $9 for adults and a little less for children.
