[/caption] Another milestone for the Mars Exploration Rovers: Spirit has been operating on Mars for 2000 sols, or Martian days. Who would have ever thought the rovers would last this long? But here they are, still going, um, pretty strong. Even though she's got plenty of electrical power, Spirit is currently stuck in loose soil at her location, called Troy. But engineers are working hard to figure out how to set her free. Check out the latest on the efforts at the

Free Spirit website.

To celebrate Spirit's milestone,

Unmanned Spaceflight's

Astro0 has put together a Sol 2000 poster over at his website,

Astro0 in Space.

It's gorgeous, and includes a

new poem by my pal Stuart Atkinson
