Ewellix planetary roller screw lands on Mars
02 August 2021
Ewellix has developed and manufactured a planetary roller screw that recently landed on Mars as part of NASA’s Mars 2020 Perseverance Rover Mission.
Ewellix engineers worked in collaboration with NASA’s Jet Propulsion Laboratory (JPL) at the California Institute of Technology, to develop a roller screw component for the Perseverance Rover that would be robust enough to withstand the extreme conditions of outer space and Mars, which can reach -80°C.
After a 203-day journey, the Perseverance Rover, the largest and most advanced rover NASA has sent to another planet, has touched down on Mars to search for signs of ancient microbial life. The Rover’s mission is to collect Martian rocks, and extract and seal samples for testing and onboard storage. The mission team of NASA scientists will then decide when and where the Perseverance Rover will leave the samples for pick up by a future mission in approximately 2031, to bring them back to Earth for detailed analysis...
