Today, NASA successfully landed a large and sophisticated mobile laboratory on Mars. While true that it was two years later than planned and $900 million over budget, this represents one of the few successes in Mars landings (70% of previous missions to Mars have ended in failure). NASA Administrator Charlie Bolden compares the challenge of Mars expeditions to launching something from Kennedy Space Center and having it land in the Rose Bowl, on the 50-year-line, on a Frisbee.
