Exciting things happen in the world of spaceflight every day. At Vis Viva, we do our best to keep track of these and discuss the most recent developments. As such, we have monthly news round-ups, where one of our members presents the events of the past month. This presentation was given by Ingo Gerth at our sixth bi-weekly meeting in Delft, May 29, 2013. ============== It shall be pointed out that our meetings are about more than just slides—they are about the interaction of our Fellows. Vis Viva offers a forum for the active discussion of space topics, and so our talks are lively get-together with a permanent conversation of the speaker and the audience. Since just slides cannot get this across, we kindly invite you to join one of our bi-weekly activities.
