Spirit and Opportunity Keep On Roving!

The two Mars rovers, Spirit and Opportunity, have had their missions extended for another six months, which is good news for space buffs and taxpayers alike. The space buffs will get even more data from the red planet now instead of much later and the taxpayers get a better return on the $400-million-plus spent on this mission already. Considering Earth's dismal track record where lobbing expensive hardware at Mars is concerned, that's a good thing.
