NASA recently released a video featuring one of its newest concepts for space exploration.
Meet Hedgehog: a robot intended to overcome the difficulties of navigating low-gravity environments on comets, asteroids and other space objects.
A typical rover makes its way around a mission site—say, the surface of Mars—much like a regular car.
But a small body’s microgravity makes driving around a dangerous proposition—the rover could float away or tumble over and the mission would end.
Hedgehog is different. It's basically a box with spikes and wheels on the inside. And brakes for those wheels.
When those brakes are pulled, the box hops an
