The James Webb Space Telescope is the most powerful space observatory ever built. Its five-layer sunshield depends on Vulcan Spring's Conforce® Constant Force Springs to maintain precise, consistent tension throughout operation in the thermal extremes of deep space.
The Double Asteroid Redirection Test (DART) was humanity's first planetary defense mission, a high-speed kinetic impactor designed to alter the orbit of asteroid Dimorphos. At launch, the spacecraft's solar array was stowed tight against the body to fit launch constraints. At the right moment, Vulcan Spring's Hinge Springs actuated deploying the array cleanly and reliably to power the satellite through deep space.
Vulcan Spring custom spring solutions are integrated into LEO satellite platforms across deployment mechanisms and positioning systems. Engineered to survive launch loads, thermal cycling, and the vacuum of space, our springs deliver repeatable performance across the full service life of the satellite.
