[2] Tsou has served as the principal investigator (PI) for several missions conducted on the Space Shuttle and Mir, during which he devised the method of intact capture for hypervelocity particles.

Collaborating with scientists from Lawrence Livermore National Laboratory, he contributed to the development of a lighter aerogel specifically designed for capturing cometary particles.

[8] Additionally, he played a role in introducing aerogel as a flight-qualified variable density material and capture medium for space missions.

Furthermore, Dr. Tsou has made contributions to the field of space thermal insulation by inventing an integrated aerogel thermal-structural design for the Mars Pathfinder Sojourner rover.

[9] His research interests extend to investigating the potential exobiological effects of extraterrestrial bodies and exploring methods to retrieve samples of materials from other planets.
