Haha...trick question. Mars is currently 154,162,003...wait 154,162,027...wait 154,162,055 miles away. That means that by the time it lands early tomorrow morning at 1:30 AM EDT, it will be a little under 14 minutes before we actually get the first signals from the surface. If it makes it to the surface in one piece. That's no knock on the people working this project, just a recognition of how difficult it is to land a rover from 154,000,000 miles away and about a 14 minute time lag.
And by the way: How cool is it that you can google "current distance to Mars" and Bam!, there's a website with the answer? Is this a great country or what?
