Dress up and join the Armstrong Air & Space Museum as the organization hosts its annual Halloween event, Boo! On the Moon. For this eerie affair, the museum galleries will be adorned in spooky and festive props and decorations. The museum will be handing out candy and treats for children who visit these days. To help with costs, the museum will also be offering half-off admission to children 12 years and younger who are dressed in a Halloween costume.
