I'll bet you were wondering just who (or what) the heck Spirit is. LOL! Well, Spirit is the Mars Rover that landed on Mars five years ago today. Twenty-one days later Opportunity (a second rover) joined Spirit on Mars. It was hoped that these two rovers would last at least 3 months...... That was five years ago! Not that the two haven't had problems. Poor Spirit can only go backwards now, and Opportunity has a problem with one of his arms. They've also had a few power problems. Both rovers get their power from the sun using solar panels. Dust tends to cover up the panels causing a power shortage.
Still, all things considered, these two tough little rovers have definitely gone above and beyond. Want to get the whole story? Click Here for the BBC News article. And Here for some photos sent back by Spirit and Opportunity. Things like this just fascinate me.
