Carmack's Armadillo Aerospace made an attempt on Sunday to cash in on this year's X Prize Cup by having their Lunar Lander hop from launch and landing pads, simulating a real lunar landing. Unfortunately, even after two successful runs, the craft's engine exploded shortly after ignition on what would be their final attempt. Carmack said, simply, "Today is officially a bad day when it comes to our vehicle." True enough, John. We just hope you didn't feel too distracted by all the wonderful treats brewing at your other job as a game designer 'cause then, we'd feel really guilty.
