Geospatial World 03/17/2021 1 Minute Read Cobham Mission Systems, the worldâs leader in critical control solutions, today announced that its space pyrotechnic valves on the NASA Perseverance rover mission enabled an historically precise landing on Mars. During the final minute of the flight, as the rover shifted from parachute to retrorockets to control the descent, eight pyrovalves fired precisely on cue. Opening instantaneously, the pyrovalves allowed exactly the fuel required to support a guided entry, descent and landing on Mars, which placed the rover within the targeted landing ellipse.  âCobham Mission Systems is so proud to support NASAâs Jet Propulsion Laboratory with proven space propulsion solutions that power Mars exploration,â said Craig Ryan, integrated product team director for Space Systems at Cobham Mission Systems. âWe have a long heritage of providing space technologies, starting with the design of John Glennâs breathing regulator used in the world-famous Project Mercury flight in 1962. Nearly sixty years later, we are delighted to play a role in the successful Perseverance rover Mars landing. Congratulations to the NASA JPL team and all involved!âÂ
