They will probably be, if they are there at all, microscopic. I miss big aliens. Which is why I loved reading this science paper. Could big be back?

August 5, 2013 In its first year on the red planet, the six-wheeled rover has driven a little bit more than a mile, drilled into rocks and performed chemical and mineral analysis. Its next journey is a 5-mile trek to the foothills of Mount Sharp to help study Mars' watery past.
August 4, 2013 Japanese-built Kirobo, which measures at just over a foot tall and looks something like a child's toy, will act as a shipboard companion to future ISS Commander Kochi Wakata.
