Whenever I look at our orbital neighbor, at the scars on the moon's surface from impacts over history, I truly stand amazed that more events like what occurred in Russia on Friday do not occur more frequently. As if the moon is tells a cautionary tale reminder to keep one eye on the sky, you never know what's coming :)
As for DA-2012. When it was first announced, I used NASA's own tracking app and varied data models did show an impact with Earth. Over time, that changed. It's always interesting to watch those models change as new data sets get parsed and added, making the models more accurate. Fun stuff!
