40 days and counting. The long wait is almost over!
I wonder whether we will get enough data to test new simulation theories like this one. http://space.newscientist.com/article/mg19...solar-wind.html What do you expect from this first flyby? |

Well, it has been about 33 years since the last measurement of Mercury's magnet field. I would assume that the best science on this flyby will be from the Magnetometer.
The really good image operation will be very short indeed. It should last only 10 to 15 minutes for some close-up visuals once the spacecraft comes out from behind the planet. The imaging could start at 4000 km from the surface and continue as the spacecraft recedes. But the exciting part is that that part of Mercury has not been imaged close-up before. Granted, it is not at the closest approach of 200 km; but 4000 km is good. Despite the visuals we might get, I'm more excited about the potential for Mapping out Mercury's Magnetic Field. I'm afraid a single pass is not good enough to do that with a high degree of confidence; but I'm hoping we will get a few surprises that will give us a much better model than we currently have. |
