SpaceBalls To infinity and beyond.. The ball is very well suited to space exploration, since it is light, can be inflatable, has protected "inner atmosphere", is power efficient, fast, etc. There are also some special Aero/groundbot versions (kind of UAV, umanned aerial vehicle combined with the usual ground capabilies!) which should be suitable in some planets with atmosphere. Maybe some spherical robots /groundbots will go to the moon in either the Google Lunar x Prize ("aka Moon 2.0"), or in the Swedish Luna Resort project by Mikael Genberg. Please note that one of the pictures above is a montage, of a photo from the Planetary Society, and a 3D-rendered ball. The other one is a illustration of Luna Resort.
