Moog products ensure a successful Mars Rover landing

Moog Inc. (NYSE: MOG.A and MOG.B) today announced that the company's space products have played a critical role in NASA's successful Perseverance Rover landing on Mars. Perseverance is NASA's latest mission to explore Mars and builds on the success of the 2012 Mars Curiosity Rover mission. The Moog team designed, built and tested several components necessary for the mission. During the final descent, the Moog throttle assemblies controlled the inlet spacecraft's engines. The spacecraft entered the atmosphere at 12,500 miles per hour, stabilizing and lowering the level of the Perseverance Rover until it successfully touched Lake Crater at approximately 4:00 p.m. ET today.

Moog also played a key role in launching the Rover on the Red Planet. The mission fired from Cape Canaveral, Florida, on July 30, 2020. Moog propulsion took the launch vehicle out of Earth's atmosphere. In addition, Moog rocket engines were used to steer a 350 million-mile spacecraft carrying the Perseverance Rover, ensuring it stayed on course at 55,000 miles per hour. With Rover now safe on the Red Planet, Moog technology will continue to support the mission. Moog valves and filters will help keep the Rover drill clean when digging samples during one Mars, which is 687 days on Earth.

"I am proud of the work that our talented and dedicated team members have put into this project to ensure its success. Their ingenuity and commitment drive innovation and the continued success of Moog, our local community, and exploring worlds beyond our own, ”said Maureen Athoe, president of Moog’s Space and Defense. Steve Witkowski, market manager for space electronics, added: “From the engineers who create the individual hardware, to our technicians integrating the individual components into a larger system, it is truly a mission in a mission. It's unbelievable to think that your work is an important element in exploring another planet.

"Mars 2020 is another major step forward in space exploration and another significant success in Moog's Space and Defense," added Steve McDonald, manager of propulsion engineering. "Seeing how our hardware successfully fulfills such an important mission is both inspiring and fulfilling."
