I have looked forward to this as much as I still look forward to the New Horizons probe to the outermost edge of the solar system, to Pluto.
Mercury has some exhilarating mysteries, and I look forward to seeing the probe unlock them.
Some things will become clear but it'll be like cutting heads off the Hydra. But that's the fun part of science - every question answered seems to raise many more.
Hear hear. Here's to the questions. The foundation, root, body and crown of science.
Looks like you don't want to be there when it 'rains'. But it's amazing how far the impact of the big crater reaches. I wonder if these are cracks in the surface or sprays of dust.
Why aren't there that many craters in Earth?
Any other boomers think back to the days of John Glenn?
