MUNCIE, Ind. (AP): Visitors will have chances to touch a moon rock during upcoming exhibits in Indiana.
 
       The opportunity comes during visits by a free NASA exhibit to Indianapolis and Muncie. The exhibit will visit Ball State University on Friday and White River State Park in Indianapolis on Saturday.
 
       The exhibit includes one of only eight moon rocks that visitors can touch. The nearly 4 billion-year-old rock was returned from the moon during the last lunar mission in 1972.
 
       Another exhibit will be set up at the Indiana State Museum through June 29 and three astronauts will be visiting Indianapolis as part of the events.
 
       Various presentations also will give the public a chance to learn about life on the International Space Station.
