NASA welcomed hundreds of children and accompanying adults to its INFINITY visitor center on Aug. 4, offering Mars-related activities that focused attention on the space agency's Curiosity mission to the Red Planet. Parents and children, such as Myron and Trey (age 3) Cummings, enjoyed exploring Mars using an interactive touch table. Midway through the day of activities, visitors in the Science on a Sphere auditorium also enjoyed a presentation on Mars and the Curiosity mission by Dr. Steven Williams, a NASA expert on Mars.
