Lab replicates outer space to test new robot

Mario is a new robot being tested at Cranfield University

Scientists have built a lab that replicates the conditions of space to test how robots could assemble large structures in orbit.
Cranfield University is testing Multi-Arm Robot for In-Orbit Operations (Mario) at the Astra-Lab in Cranfield, Bedfordshire, a facility simulating the space environment.
Mario's development aims to make space-based projects such as solar power panels and large telescopes viable.
The Astra-Lab and Mario will be used for testing various space missions and provide both academics and students with hands-on experience in space robotics.
Astra-Lab stands for Advanced Space Technology for Robotics and Astronautics laboratory.
The purpose-built facility has a friction-free floor and a projector system to replicate light from the Sun.
It also uses a compressed air system to simulate working in free-floating conditions.

Astra-Lab was opened by Lord Patrick Vallance, minister for science
Mario will initially be controlled from Earth with a future goal of autonomous operation.
It is hoped large structures can be sent into space in a flat-packed format, alongside a robot like Mario to carry out assembly.
Cranfield's Dr Leonard Felicetti designed and built the robot.
"Having a cutting-edge facility like this gives us an opportunity to be right at the forefront when it comes to both space robotics and guidance, navigation and control," he said.
