He served on design review boards at Goddard and received a 30-year service award from NASA in 2013.

Mr. Salerno enjoyed hunting and judged competitions for the Potomac Chapter of the National Association of Versatile Hunting Dogs of America and the D.C. Chapter of the Weimaraner Club of America. He was an amateur radio operator and a member of the American Radio Relay League. He also was a member of the Bethesda-Chevy Chase chapter of the Izaak Walton League of America, a conservation group.
