He was predeceased by: his significant other Lori Jean Mattus; his parents, Joseph Mattus and Kathryne Mattus; and his sister Karen Mattus. He is survived by: his children, Jessica Sitton (Josh), Kyle Mattus (Vanja Vermezovic) and Cynthia Roberts (Dustin); his grandchildren, James Allen, Caranean Janice, Ethan Aleksander, Isaac Martin, Jackson David and Nora Jane; his sister Teresa Smotherman (Charlie); and his father-in-law Larry Olson.
His passion for technology and space converged in one of the achievements he was most proud of—his contribution to the Mars 2020 mission, where he worked on the mechanisms used in the Ingenuity helicopter deployed alongside the Perseverance rover.
