Beneath the seemingly simple exterior of an F/A-18 Hornet, cruising at the speed of sound above the vast Californian landscape, a revolution in space navigation unfolds. Strapped underneath its wings, NASA has tested an extraordinary commercial sensor technology that promises to transform how robots and astronauts will one day land on the Moon and Mars.
Envisioned by Psionic, Inc., the Psionic Space Navigation Doppler Lidar (PSNDL) epitomizes the synergy of innovation and collaboration. Rooted in original NASA technology, Psionic has artfully miniaturized this tech while enhancing its functions and durability—rendering it tough enough for the harsh realities of spaceflight. The PSNDL system doesn’t stand alone; complemented by cameras and an inertial measurement unit, it forms an all-encompassing navigation toolkit. Together, these components accurately chart a vehicle’s position and velocity, leading the way to precision landings and beyond.
This February, NASA’s Armstrong Flight Research Center in Edwards, California became the launch point for this endeavor. The F/A-18 darted through the sky, sketching a massive figure-8 over the iconic backdrop of Death Valley. Through brisk maneuvers, the aircraft gathered crucial data across a mosaic of speeds, altitudes, and angles—data that will one day guide spacecraft through the treacherous terrains of lunar valleys and Martian landscapes.
Doppler Lidar technology, the backbone of this system, captures speed with exquisite accuracy. It harnesses the Doppler effect, observing shifts in laser frequencies as they bounce off Earth’s surface. Its prowess truly shines in sunlight-deficient areas like the lunar South Pole, where harsh contrasts demand precision. Coupled with the ability to visually reference rocky surfaces from above, the PSNDL empowers spacecraft to land safely and with pinpoint accuracy.
But Psionic’s journey from mere concept to cutting-edge technology wasn’t solitary. Since 2016, nurturing hands in NASA’s camp—bolstered by initiatives like the Small Business Innovative Research program—have supported Psionic’s progression. Field tests on suborbital vehicles and vital funding from NASA have smoothed the path to its current iteration. This collaboration culminated in 2024, when the predecessor NDL system onboarded a commercial lunar lander for a successful trial.
The unfolding narrative of PSNDL is a testament to human curiosity and persistence. As it makes strides toward maturity, this technology signifies more than a technical milestone—it beckons a new era where mankind strides confidently onto alien soil. The message is clear: the frontiers of space are within reach, and the toolkit to explore them is taking shape today.
