Nasa has blasted a new piece of kit into space - a virtual reality headset that will beam what the crew on the International Space Station see back to earth.
The organisation has launched Project Sidekick, a collaboration with Microsoft's VR headset HoloLens, that it hopes will speed up repairs and research on the ISS.
In the future, it hopes to use the technology on missions to Mars and an asteroid.
Nasa last month sent two pairs of the headset to the ISS, around 354km from the earth's surface. Astronauts are expected to be using them by the end of the year.
The devices will be used in two ways. First, it will beam a crew member's view back to experts on the ground, who will be able to coach them through operations such as repairs, and "draw" on top of the astronaut's view to help them. Secondly, augmented reality software will put holographic pictures on top of an astronaut's field of vision, which Nasa says will speed up training.
