An aerospace engineer by training and trade, Keegan has designed, built and tested everything from boost pumps to satellite demonstrators. He’s taken part in dozens of rocket tests, led university projects to cast solid rocket motors and helped design unmanned missions to Ceres.

In the summer of 2015, Keegan founded RedWorks with Paul Petros, Susan Jennings, and Lino Stavole to compete in and make it to the finals of the AmericaMakes / Nasa Centennial 3D Printed Habitat Challenge. Keegan and his team are creating a way to 3D print whole buildings on the Moon, Asteroids and Mars using just local materials, quite literally laying the groundwork for human settlement of the solar system.
