NASA’s Perseverance Rover and Ingenuity Mars Helicopter are exploring Mars hundreds of millions of miles from Earth, but Rocket Center visitors can see their “twin” models beginning Sept. 2, in the “Dare to Explore: Frontiers of Space” exhibit. The Rocket Center is the only stop in the Southeast for the “Roving With Perseverance” roadshow, which showcases the model rover and helicopter. The rover is as big as a car while Ingenuity is tiny in comparison.
