These great hollow globes of artificial super-metals, and artificial transparent adamant, ranged in size from the earliest and smallest structures, which were no bigger than a very small asteroid, to spheres considerably larger than the Earth. (Olaf Stapledon, STAR MAKER)

Murray Ridge
Mars Exploration Rover Opportunity settles into it's winter work area, Murray Ridge, on the western rim of Endeavour Crater on Mars. Opportunity's ninety-day (Sol) mission started in 2004. Think about that. That is one hell of a return on investment. I wish my car would work that long between repairs!
