He's gotten to Mars in the begging of 2004. He landed with a bouncy airbag, and got out safely. At first he could only find lots of volcanic rocks, and some thought Spirit was a failure and that volcanic rocks weren't interesting.
(in my opinion, what rocks is that he actually went to another planet and took pics there.)
And he conquered Columbia hills, a Martian mountain.
He had luck too. When dust settled on the solar panels and seemed like the rover would shut down because of energy loss, a miraculous "dust devil"(sorta like little tornadoes) came and washed the sand away.
But it finally ran out of luck when one of its wheels stopped working and stuck in the sand.
March 22, 2010 was the last time JPL communicated with Spirit.
And a while ago, NASA announced it would stop searching for Spirit.
I guess this had to come sooner or later. We still have Opportunity, and yes, there is the new rover Curiosity launching later this year.
Martian exploration is just beginning.
Martian sunset- breathtaking.
