Houston Museum of Natural Science question

I got tickets for the permanent exhibit & tickets for a planetarium show. The exhibit starts at 12:00 Pm and the planetarium show is at 1:00. Will I be able to go back to the exhibit after the show to continue where I left off? I thought I had gotten tickets for 11:00 but I was wrong. I don’t think I’ll have enough time to see everything in an hour before the show starts. I checked their FAQ but was not able to find an answer for this. Any help is appreciated!
