Peter Tsou is a principal science staff member at the Jet Propulsion Laboratory (JPL) of the California Institute of Technology, where he has worked for the past 34 years.^[1] Dr. Tsou's research was focused on using aerogel for space exploration.^[2]

Dr. Tsou was a Principal Investigator (PI) for a number of Space Shuttle and Mir missions, and was responsible for inventing the technique of intact capture of hypervelocity particles. In addition, his work revolutionized the use of silica aerogel for space missions. He is most famous for his work involving the capture and return of comet particles via NASA's Stardust mission, to which Dr. Tsou served as deputy PI.^[3]

Education[]

Dr. Tsou earned B.S. (1965) and M.S. (1966) in Electrical Engineering at the University of California, Berkeley. He received his PhD in Large Scale Engineering Systems from the University of California, Los Angeles, in 1972.^[3]

Career[]

Since 1974, Dr. Tsou has worked at NASA's Jet Propulsion Laboratory, located in Pasadena, CA. He has been involved in multiple projects, most recently as Deputy Principal Investigator (PI) of STARDUST (1994–present). Prior to this, Dr. Tsou served as PI for the MIR Sample Return Experiment (1994–1997), PI for Spacehab II Sample Return Experiment and STARDUST proposal manager (1992–1994), PI for Get Away Special Sample Return Experiment (1989–Present), instrument definition manager (1984–1990), spacecraft system engineer (1982–1990), Task Manager for the Low Cost Solar Array program (1975–1980), and a system engineer (1974–1975).^[3]

Prior to his work at JPL, Dr. Tsou worked at University of California, Los Angeles, as a project manager on the Climate Impact Assessment Program of the Supersonic Transport (1970–1974), and at TRW as a technical staff member (1966–1968).

Research[]

His research interests for the past two decades have concentrated on achieving a sample return of cometary coma material. He invented the technique of intact capture of hypervelocity particles for just such a mission as Stardust, the 13th proposal for a comet flyby sample return mission. Working with scientists at Lawrence Livermore National Laboratory, he made the aerogel material lighter and more suitable for catching the comet particles.^[4] He has also introduced the use of aerogel as one of the capture media and flight qualified variable density aerogel for space flight.

Dr. Tsou has donated several samples of aerogel for several museums: JPL's museum, located on their main campus in Pasadena, CA;^[5] the Kirkpatrick Science & Air Space Museum, also known as the Omniplex Science Center, for the first public display of the traveling "Stardust Cafe" exhibit;^[6] Santa Monica College for display in their science complex.^[2]

He was the principal investigator for a series of Shuttle Sample Return Experiments and Mir Sample Return Experiment with silica aerogel he made at JPL. He continues to develop improved techniques to identify, remove and study particles captured in aerogel.

Dr. Tsou was responsible for inventing an integrated aerogel thermal-structural design for the Mars Pathfinder Sojourner rover, another breakthrough for space thermal insulation.^[7]

His other research interests include exobiological implications of extraterrestrial bodies and methods to sample extraterrestrial materials.
