The original PlayStation's CPU is powering the New Horizons space probe.
The New Horizons space probe which recently completed a flyby of Pluto and beamed new images of the planet back to Earth is being guided by the same CPU which powered the original PlayStation console. As reported by The Verge, the probe contains a MIPS R3000 CPU, repurposed to "fire thrusters, monitor sensors, and transmit data."
Various gaming hardware have been employed by NASA in its past projects, including use of the Kinect and Oculus Rift to control a robotic arm in real time. NASA has also revealed plans to use Microsoft's HoloLens augmented reality headset in the International Space Station, where it will provide support and guidance for day-to-day actions.
