About
Northrop Grumman’s pulse tube cryocoolers are designed for high reliability in critical space missions, including applications in missile defense, climate science, astronomy, and weather tracking and prediction. These cryocoolers have a significant flight heritage, having operated on-orbit for more than 300 combined years. A key feature of these pulse tube cryocoolers is their operation without moving parts, which contributes to their exceptional longevity, often exceeding their designed lifespan many times over without any degradation in performance. They are capable of supporting demanding and complex space missions, such as NASA’s James Webb Space Telescope. The designs are scalable, making them suitable for both large-scale, robust spacecraft and smaller, more proliferated spacecraft designs.
