On Thursday morning, NASA will launch its fifth Mars rover: A robotic scientist the size of an SUV. The $US2.4 billion, nuclear-powered vehicle, named Perseverance (“Percy” for short) is designed to trundle along the Martian surface, mine for signs of ancient life, capture high-quality video and audio, and collect rock and soil samples for an eventual return
