"Curiosity" had been bound for Mars since it hitched a ride aboard the United Launch Alliance Atlas V rocket last November from Cape Canaveral.
After 352 million miles and $2.5 billion dollars, NASA's rover finally landed on the surface of the Red Planet. Or at least, NASA hoped it will land--with is payload of fancy gadgets for studying Mars once it arrives, a lot was riding on the success of a tricky maneuver.
Over a period of about seven minutes, the spacecraft containing Curiosity--actually a car-sized rover contained inside a larger craft--decelerated from 13,200 miles per hour to zero in the space of 390 miles.
Everything went as well as hoped, and Curiosity will spend two years exploring Mars looking for signs that our nearest planetary neighbor has or ever had the ability to support and sustain life.
You can watch a replay of the tense, giddy landing, and the jubilant celebration of the NASA scientists when it landed successfully.
"Curiosity" also sent back several photos, and later, a video of the landing from her own cameras.
