Nature’s Flight System Could Be Key To Exploring Mars SpaceDaily

One of the oldest forms of flight — the flapping wings of insects — may support a revolutionary new class of robotic flying machine uniquely suited for exploring a brave new world: the planet Mars. The thin Mars atmosphere, composed mostly of carbon dioxide and lacking oxygen for combustion, provides an inhospitable environment for conventional aircraft and helicopters. Compounding the challenge are size constraints imposed by the spacecraft delivering air vehicles to Mars. But the flapping wing “Entomopter,” a patented mechanical insect capable of both flying and crawling, may be ideal for meeting the demanding requirements of Mars aerial exploration.
