One of Greenaugh's significant contributions involved managing a program focused on defending the planet from potential collisions with near-earth-objects. His research in this area resulted in technical papers published in reputable outlets like Physics Today and the New York Times. ^[3] Furthermore, NASA benefited from his work, with two technical reports, "Studies of Short Time Response Options for Potentially Hazardous Objects"^[4]and "Multi-Organization – Multi-Discipline Effort Developing a Mitigation Concept for Planetary Defense."^[5] With over 35 years of experience, Greenaugh left an indelible mark on the nuclear enterprise and energy industry.^[6] His tenure at MITRE Corporation and Los Alamos National Laboratory showcased his prowess in handling national energy issues and contributing to research on energy and nuclear non-proliferation.

Greenaugh's commitment to education was evident through his role as an adjunct professor at Howard University for over twenty-five years, where he imparted knowledge in the School of Engineering. ^[7] where he taught courses in the School of Engineering. He also shared his expertise at the US Air Force Academy.

In addition to his professional achievements, Greenaugh was a devoted member of the Omega Psi Phi fraternity's Gamma Zeta chapter, highlighting his commitment to community and camaraderie. His life and career stood as a testament to resilience, excellence, and contributions to both scientific advancements and societal progress.

In 2006, he was awarded the Black Engineer of the Year award for achievement in government, by Career Communications and cited at the A. James Clark School of Engineering, University of Maryland.^[8] He also received the Centennial Award for Science from the Omega Psi Phi fraternity in 2011, the National Trail Blazer Award in Science and proclamations from multiple cities.
