Every week, Supercluster recaps the biggest stories from space exploration. 

This week: Supercluster's Robin Seemangal is joined by contributor and launch expert Chris Gebhardt and spaceflight photographer John Kraus. They share their experience just a few hours after witnessing the retirement launch of the powerful Delta IV Medium rocket from Florida's space coast. We also discuss Skybot-F850, the Russian-built humanoid robot sent to the space station last week, who definitely does not resemble Chappie.
