Zeldovich Medal awarded to Japanese researcher for research results of fluid dynamics experiments on-board "Kibo" at COSPAR 2018

Last Updated: September 13, 2018

At COSPAR 2018, the scientific assembly of the Committee on Space Research (COSPAR) held on July 14 - 22 in the US, Dr. Taishi Yano, Assistant Professor of Faculty of Engineering at Yokohama National University, was awarded the Zeldovich Medal. The medals are conferred by the Russian Academy of Sciences and COSPAR to young researchers for their outstanding contribution to space research.

Dr. Yano has been involved in Marangoni convection experiments* using the microgravity environment on-board Japanese Experiment Module "Kibo" on the International Space Station (ISS) since 2009. His internationally recognized contributions to research, including both discovery of a new convection structure with improving measurement technique and clarification of the fluid transition conditions, gave him the medal.
