NASA's JSC Project M : Humanoid on the moon

Project M is a proposed project to land an operational humanoid robot on the moon in 1000 days (M is the Roman numeral for 1000). The humanoid will travel to the moon on a small lander fueled by green propellants, liquid methane and liquid oxygen. It will perform a precision, autonomous landing, avoiding any hazards or obstacles on the surface. Upon landing the robot will deploy and walk on the surface performing a multitude of tasks focused on demonstrating engineering tasks such as maintenance and construction; performing science of opportunity (i.e. using existing sensors on the robot or small science instruments); and simple student experiments.
