Last night, in honour of the New Horizons mission to Pluto, I pulled out my copy of Solarquest. This classic board game was a childhood favourite of mine, and it’s basically Monopoly in space: instead of buying properties named after streets in Atlantic City, New Jersey (or London, if you’re British), you buy planets, moons and artificial satellites. Then, when your fellow players land on an object you own, you charge them rent.
Such nostalgia is all well and good, I hear you say, but what’s it got to do with New Horizons or Pluto? Well, Solarquest’s inventors clearly took their science seriously. By board game standards, there’s quite a lot of physics in it. For example, you can’t leave a planet unless you roll a number high enough to overcome its gravitational pull, and its Monopoly-like property deed cards include facts about each planet and moon as well as their prices.

After trundling through our solar system for more than 10 years, NASA’s New Horizons mission made its closest approach to the dwarf planet Pluto earlier today, at 12:49 BST. It was a mere 12,472 km from the planet’s surface – roughly the same distance from New York to Mumbai, India – making it the first-ever space mission to explore a world so far from Earth.
If you want to find out more about the New Horizons mission, read this recent news story by physicsworld.com editor Hamish Johnston. Above is best close-up view of this cold, unexplored world that the spacecraft sent back before its closest approach (when it was still 766,000 km from the surface), revealing in clear detail many of the planet’s surface features, including the “heart” at the bottom.
