The unexplained 2023 death of NASA scientist Michael David Hicks has renewed scrutiny over a series of recent deaths and disappearances among scientists linked to sensitive U.S. research programs.
The death of NASA research scientist Michael David Hicks has renewed scrutiny over a pattern of deaths among scientists linked to sensitive U.S. aerospace and defense programs. Hicks, who worked at NASA Jet Propulsion Laboratory from 1998 to 2022, died on July 30, 2023, at age 59. Nearly three years later, records show his cause of death has not been publicly disclosed.
Hicks contributed to major space missions, including DART Mission and Deep Space 1, and authored more than 80 scientific papers. According to reports, his case is among several recent deaths or disappearances involving scientists tied to U.S. space or nuclear research programs, prompting concern among national security observers.
Other cases cited include the disappearance of Monica Reza in 2025, the death of JPL engineer Frank Maiwald in 2024, and the killing of astrophysicist Carl Grillmair in February 2026. Former Federal Bureau of Investigation official Chris Swecker warned that foreign adversaries have long targeted Americans with access to sensitive technologies.
