If We Can Put a Man on the Moon, Why Can’t We Put a Man on the Moon?

Interesting, I didn't realize Earth's gravity was still so strong at 500km up. Getting payloads to the station from space would still be cheaper because we could rely on aerobraking, but accelerating mass to Earth escape velocity from LEO would require an extra 1km/s of delta-V compared to the Moon. I think the Moon might make sense if we can mine significant materials from it, but I haven't read much about what's there.

Yup, our well is steep :).

See also this subway-style ∆v map of our system (inspired by a similar map for Kerbal Space Program): http://i.imgur.com/AAGJvD1.png. I feel it would work great as a poster on a wall.

The map really brings home the point that "Low Earth Orbit is halfway to anywhere in the Solar System".

Neat pic (after I figured out I had to zoom in to see the destinations). It's just missing the route from the Moon to Earth Intercept(/Escape). I'd also love to see these maps include routes to the asteroid belt from the Earth/Moon/Mars.
