Assuming you're the driver in the car in the attached photo, can you estimate your "geographic position" or GP? That is, what point is directly beneath you on the Earth? The photo is 100% real, by the way, taken just an hour ago. It's Elon Musk's old Tesla as a dummy "test mass" for the launch of the Falcon Heavy rocket. This is not CGI. The only aspect of the photo that isn't real is the driver. That's just an empty suit. Meanwhile, you can watch a really spectacular live feed from orbit for the next few hours: Tesla in orbit. There's not much science in this, but it's great theater!
