Polaris Rover

The Polaris Rover is a mobile explorer that prospects for water at the lunar poles. Polaris carries up to 120kg of payload, such as a drill to take core samples and science instruments to identify water content.
Polaris has three vertical solar panels to generate 250W of power and two radiator panels to reject excess heat. Stereo cameras and laser guide Polaris and generate 3-D video and models of the lunar surface. The robot communicates directly with Earth using a pointed S-band antenna to receive commands and send video and data. Polaris is capable of driving and avoiding obstacles autonomously, including traverses into dark regions in the lunar pole’s long shadows. Polaris suspension maintains four-wheel ground contact over sloped and rocky lunar terrain without the use of springs.
