About this shelf
Three small instruments built on public data and published physics. Each takes one phenomenon and puts it on a phone: the asteroids passing close to Earth in the next hundred years, the muons from cosmic rays hitting your screen right now, and the fuel a ship burns because of the growth on its hull.
For people who watch the sky, count particles, or keep ships efficient.
