Roger Ludwig

Roger Ludwig received his B.S. degree in management from Oakland University, Rochester, Michigan, in 1981 and his M.B.A. degree in finance from California State Polytechnic University, Pomona in 1996.

Roger began his aerospace career in 1981 at Altair Radar, Kwajalein Missile Range, the Marshall Islands, where he performed radar skin tracks of Earth-orbiting objects for the North American Aerospace Defense Command (NORAD) Space Detection and Tracking System (SPADATS). He eventually became a SPADATS operations director.

In 1985, Roger joined the Jet Propulsion Laboratory (JPL) and gained exposure to spacecraft operations and the Deep Space Network as a spacecraft mission controller on the Active Magnetospheric Particle Tracer Explorers (AMPTE) mission. He transferred to the Communications Systems and Research Section in 1989 and performed telecommunications analysis supporting the NASA Voyager spacecraft (interplanetary mission) Neptune encounter and Voyager Interstellar Mission until 1997. He assisted with Magellan (mission to Venus) on-orbit mapping, Galileo (mission to Jupiter) launch and Venus and Earth flybys, and launch of the Mars Observer spacecraft.

Roger left JPL in 1997 to work for TRW Corporation as a satellite system engineer on the Defense Support Program. In 1999, he returned to JPL and the Communications Systems Research Section to perform telecommunications analysis supporting the Cassini Project (to Saturn). He transferred to the Flight Systems Section in 2000 and returned to the Voyager Interstellar Mission, with broader system-wide responsibilities in the search for the edge of our solar system and first-ever collection of science observations from interstellar space.
