NASA’s newest exploration rover, dubbed Axel for its design, can climb steep and rocky terrain and explore deep craters on planets like Mars. It uses only three actuators to operate upside down, right side up, turn in place, and follow illogical paths. Axel can maneuver autonomously using cameras, sensors, and wireless communication, or be tethered to a larger spacecraft.
NASA’s mars exploration rover, Opportunity, has trekked the surface of the Red Planet for five years. It discovered the first signs of ancient ice and is helping to answer the question: Is there life on Mars?
