Check the website tickets
While this question is more appropriate for the web site or the museum, itself, I can tel l you that the exhibit can be incredibly crowded. Go early. Really really interesting, however.
When you buy tickets at the museum for the same day, they will tell you what times are available because you need to get the headphones
I think members r able to get day of tickets. So if you show up early and r willing to join, I think you can get tickets for that day. You can check the website for costs.
