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)

5,000 Sols and Climbing
Pictured in the current Astronomy Picture of the Day is Intrepid Crater on Mars. This was imaged in 2010 by Mars Rover Opportunity. Originally planned as a 90 day mission, Opportunity recently passed 5,000 (!!!) days of operations on Mars.
Five thousand days into a ninety day mission. What an achievement!
Click on that image in the link. It's worth a long look.
