With the enclosed picture floating next to the instrument Soft-Matter Dynamics on the International Space Station, there will be a dedication of it to Prof. Bob Behringer's memory. The instrument was sent up by SpaceX-15 on June 29, installed by German ESA astronaut Alexander Gerst on July 19, and shall enter into regular science operations on August 2, when together with the kick-off we shall also have a dedication ceremony in Bonn, Germany.
