Three Generations of Mars Rovers

NASA’s JPL has a nice photo of two engineers standing with three generations of Mars rovers. There’s quite a difference in size when you start with Sojourner (1997) which looks like a large radio-controlled car. Next up in size were Spirit and Opportunity (2004), which are about the size of a small four wheeler. Finally there’s this year’s Curiosity, which is about the size of a Volkswagen Beetle.

This is a small version of the image. [Bigger versions are available at the JPL website](

Curiosity’s First Images of Mars

This image was used to create the larger panorama that is attracting so much attention but what I find compelling about this image is just how, well, how quotidian it is. I’ve walked places on Earth that looked like this. For the first time in a long time, I want to step foot on Mars. I want to be there.
