The 31st International Symposium on Shock Waves (ISSW31) will be held July 9-14, 2017, at Nagoya University.

About Shock Wave and Space Propulsion Laboratory

We aim for innovations in aero/astronautics and propulsion with understanding physics of shock waves and plasma/high-enthalpy flows.

Stop Rotation of Debris by Laser Ablation

Fragments of the rocket components and the satellites, the so-called “space debris”, are threatening the safety in earth orbit. It is said that more than 500 thousand of debris is orbiting with extremely high speed (7.9 km/s, for example). So, space debris mitigation is one of the most urgent problems in the space development field.
 In our Laboratory, the technique of deorbiting debris by laser ablation is studied. To demonstrate validity of the deorgiting method, we attempted to stop rotation of miniature satellite model by laser irradiation. Rotation of the model is almost terminated with generated impulse of laser ablation.
