Weekly Space Hangout - Oct. 4, 2012

It was a slow week on Space news except for the massive announcement that an ancient riverbed was discovered on the surface of Mars. We took a look at this as well as the historic 55th anniversary of Sputnik, a precise measurement of the expansion of the Universe, and more!
