- Report from the Planetary Defense Coordination Office
Lindley Johnson is assigned to NASA Headquarters Science Mission Directorate, Planetary Science Division, as the Program Executive for the Near Earth Object Programs. Prior to NASA he served 23 years of Air Force active duty, obtained the rank of lieutenant colonel while working on a variety of national security space systems. After joining NASA, he was the Program Executive for NASA's Deep Impact mission to comet Tempel 1, launched in January 2005 to deliver an impact probe to the comet's surface on July 4, 2005, and explore the composition and interior structure of short-period comets. NASA's NEO Observations program has discovered over 8,000 near-Earth asteroids and comets since Lindley became its manager, about 80% of the total known. Lindley has received NASA's Exceptional Achievement Medal for his work on comet and asteroid missions. Asteroid 5905 (1989 CJ1) is named "Johnson" to recognize Lindley's efforts in detecting Near Earth Objects.
