Current Research

Tolson’s comes to NIA with a diverse and robust research portfolio. He carries with him a relationship with NASA that is represented today in the way that his research is integrated with the efforts of NASA’s planetary entry, atmospheric science, and sensor development groups. This relationship, along with the body of knowledge and experience he possesses, lends great dimension to the experience that students and collaborating researchers have at NIA. Tolson’s interest in the exploration of other celestial bodies, terrestrial and extraterrestrial atmospheres, and sensors, integrates with NIA’s main research thrust in space exploration and atmospheric science.

Throughout his career Tolson has been directly involved in pre-flight, operations, and post flight analysis of space missions to the Moon, Mars, Venus and Titan. He has recently been involved in every NASA planetary aerobraking mission, and while in academia, he provided his students with the unique opportunity to have operational responsibilities during the aerobraking phase of the Mars Global Surveyor, the Mars Odyssey, and Mars Reconnaissance Orbiter missions. During these missions, Tolson lead students in real time analysis and interpretation of accelerometer and telemetry data to determine aerodynamic/atmospheric properties at aerobraking altitudes. Results of the interpretations were used to make daily orbit-maneuver decisions.
