Proxima team #5

“My name is Jean Mignot, I worked at CNES for 30 years in various fields, notably on satellite altitude control systems, which has led me to define an experiment called Fluidics that I’m conducting from CADMOS designed to understand how fluid sloshing affects satellite control.
I’m Thomas Pesquet’s teammate on the experiment he’s running for the Proxima mission aboard the ISS.”
