Powered descent is the key to any journey that allows for detailed scientific exploration of the kind that existed during the Apollo program. It's also how the Phoenix program landed their spacecraft on Mars in 2008. And for Moon Express, it will be the first powered descent of a lander on the Moon since Apollo 17 in December of 1972.
As for our specific propulsion system, you probably don't have a need to know, not just yet any way. But we promise, as soon as these powerful little thrusters get us safely on the Moon's surface, we'll tell the world exactly how we did it. Including the proprietary radar systems that will help guide the Lander down.
