Aircraft for Other Worlds

Future planetary exploration may draw upon a rich history of aeronautical progress here on Earth — from the Wright Brothers to centuries-old hot-air ballooning. Space engineers are charting novel ways to investigate Mars and other worlds in our solar system with innovative research underway to design robotic aerial craft that can plumb the atmospheric depths of Titan, a moon of Saturn, even slice through the clouds of Venus, or glide over the outer-planet gas giants.
