 In 2011, NASA awarded Stone Aerospace $4 million to fund the Phase 2 of project VALKYRIE (Very-Deep Autonomous Laser-Powered Kilowatt-Class Yo-Yoing Robotic Ice Explorer).This project aims to create an autonomous cryobot capable of melting through vast amounts of ice.The probe’s power source differs from many other designs in that it does not rely on nuclear power to generate heat, but rather the power of a high energy laser fed to it through a fiber optic cable.
