Preparations for Next Moonwalk Simulations Underway (and Underwater)

This project will develop piezoelectric-based power conversion for small power systems on the lunar surface. These piezoelectric systems can potentially offer high power density to significantly reduce size, weight, and cost. They can also offer high efficiency as well as resistance to the extreme lunar environment with its expected prolonged exposure to extreme cold and radiation. The effort will build and test prototype piezoelectric DC-to-DC power converters and DC-to-DC power supplies.

ECF 2024 Quadchart Underwood.pdf

This project will demonstrate a fusion propulsion system based on z-pinch which is a method of compressing plasma by running electrical current though it. The z-pinch will compress and heat the plasma to produce fusion reactions, and the system will be paired with an electromagnetic accelerator to produce thrust from these reactions. The effort intends to design, build, and test a prototype device and use computational modeling to evaluate the potential performance of larger systems which would be suitable for powering deep-space missions.

This project will investigate one of the key fundamental challenges associated with directed-energy light-sailing technology, similar to solar sails but powered by a laser beam pointed at the sail instead of by the sun. The effort will first mathematically model, then design, build, and test a prototype diffractive light sail. The three-dimensional, origami-inspired light sail could potentially unlock higher thrust, passive beam riding stability, and higher maneuverability via its ability to transform its shape.

This effort will aim to demonstrate the feasibility of directed-energy propulsion through a combination of computational simulations and prototype testing. The project will model the interactions between lightsail material and a laser beam that can be pointed at the sail to propel the spacecraft. The results of the modeling will be used to fabricate an optimized sail for testing with a 30W laser. A successful demonstration would pave the way for ultrafast spaceflight within and beyond the solar system.
