ESA’s looking to send a snake to Mars in order to learn more about the Red Planet. Now before you go “what?!” It’s not a real snake but a snake-like robot that could potentially serve as one of the arms of a Mars rover that would detach, crawl independently and exploreinaccessible areas of the planet. A smaller, more versatile snake robot could get into tight spots that bulky rovers could not reach—exploring Mars’ secrets hidden in nooks and crannies. A rover is a powerful energy source andwould power the snake-bot and if the rover gets stuck, the snake could coilaround a rock and help pull the rover free—a true symbiotic relationship.
