Axel, a research prototype rover for exploring the Moon, Mars and other planets, is remotely driven over rocks as engineers from Jet Propulsion (JPL) and grad students from Caltech (California Institute of Technology) demonstrate its mobile over the steep and rocky grounds of the JPL Mars Yard on January 14, 2009 in Pasadena, California. The rover is capable of descending cliffs or into craters and returning by a cable tethered to its starting point. Development of the Axel rover is a point effort funded by NASA Exploration Systems Mission Directorate (ESMD) and lead by Principal Investigator Issa Newnas and Co-Investigator and Caltech professor of mechanical engineering bio engineering Joel Burdick.

A set of pictures taken by Kellie Netherwood on the northern-most island located in the Inner Hebrides of Scotland perfectly captures the spirit of the Scots: wild, free, and majestic. It is no wonder that Scottish people fought tooth and nail to gain their independence all throughout their history. The green fields, rocky hills, and the beautiful waterfalls all sing to the spirits of the Scots, instilling pride into everyone who considers this place to be their motherland. However, no matter what your origin may be, you cannot help being fascinated by the beauty of these landscapes, drawn to them as if by a powerful force. (Photo by Kellie Netherwood)
