   I was staring at this confused for a minute because I'm more used to looking at the Kerbal Space Program version than the real-world one and was wondering what happened to Minmus.

   Its a shame no-one has sat down and worked these out for minimum energy transfers (or at least, some approximation thereof) instead of hohmann transfers. Bit harder than just sitting down with a calculator and the wikipedia pages for the solar system, I guess. Might be possible to cobble together some information about how much delta-v the various probe missions required from nasa and esa publications without having to think too hard about how slingshot manoevers work.

   Just curious: how come Low Venus Orbit → Venus surface is 27 km/s, while Low Earth Orbit → Earth surface is 9.4 km/s?

   Don't Venus and Earth have similar size and mass?

     If it's for KSP, they don't care a lot about orbit>surface cost because aerobraking makes that free (in theory), so the figure would be more for surface>orbit, which is made difficult by the drag in the dense athmosphere.

       Ah, OK. I was assuming the figures were without consideration of the atmosphere. Thanks for the clarification.
