Or, how to explore the solar system and be back in time for Thanksgiving. It’s no secret that I’m a space nerd. One of the major headaches of human space travel is that if you put the enthalpy of combustion, the melting point of metal, the Tsiolkovsky rocket equation, and the escape velocity of the Earth into a giant pile of nearly-linear algebra and shake it for a while it turns out that getting stuff into space is ludicrously hard. Launch from Earth to low Earth orbit (LEO) requires about 9.3 km/s of delta-v. LEO to Earth escape is another 3.2 km/s. Going to other planets, even the…
