Flexural pivots were selected for the gimbal support system of the 100-lb thrust engines aboard all five Lunar Orbiter spacecraft. Each pivot was 5/8 in. diameter × 1 in. long and shipped with a 100% reliability load test. NASA and Boeing confirmed excellent performance across all five flights — the pivots required no lubrication, eliminated bearing clearance issues across extreme temperatures, and operated flawlessly from near-vacuum to 760 torr.

NASA Goddard engineers chose Riverhawk brazed flex-pivots for the L'Ralph Scan Mirror Mechanism aboard the Lucy spacecraft — launched October 2021 on a 12-year mission to survey seven Trojan asteroids. The pivots enable a single-axis scan mirror that eliminates the need to slew the entire spacecraft, operating across −120°C to −89°C in deep space. Riverhawk's technical guidance on brazed vs. electron-beam welded pivots was cited directly in the published NASA paper.
