A live stage show for children, “Mad Mission to Mars 2025,” recently opened at the Kennedy Space Center Visitor Complex in Florida. Comedy and music, along with special effects and 3-D computer animation, transform guests into “astronaut trainees” on a virtual trip to Mars. During the show, scale-size models of planets are placed in the audience to simulate the solar system. Staff members choose volunteers from the audience to help demonstrate aspects of living and working in space.
