` He will perform songs familiar to many with a decidedly Yavapai flair. He also will provide a few lessons in the Yavapai language.

The poster exhibition, exploring the birth and development of the American space program and race, will be displayed through Oct. 15.

The exhibit is the first in a series of experiences highlighting the theme of natural and social sciences in advance of the museum’s

expansion, “Where Water Meets the Desert Sky.”

Winter hours – 10 a.m. to 4 p.m., Tuesday through Saturday – will begin Oct. 1.
