UK astronaut Tim Peake will take control of a robot in Stevenage from the confines of the International Space Station (ISS), later today.
The European Space Agency mission, entitled Meteron (Multi-Purpose End-To-End Robotic Operation Network), aims to discover more about controlling remote systems from space and how humans and robotics can work together.
The 90-minute test will involve the astronaut driving the rover prototype "Bridget" through a specially created Martian landscape at the Mars Yard Test Area at the Airbus Defence and Space station in Stevenage.
According to the ESA, he must "find up to three targets marked with UV paint and exit the cave in 90 minutes. For each target the rover must approach within two metres, centre the target in the camera view, mark map, and notify ground control."
In future, ESA plan to use the technology for exploration missions on Mars.
Major Peake arrived at the ISS in December and since then has sent a number of video messages back to earth, became the first Briton to walk in space, and last Sunday ran the London Marathon using an on-board treadmill.
