NASA: We're sending humans to Mars
If you have fuel in orbit you just have to reach it, you don't have to get to escape velocity.

OK, got that. Did some further reading (again) on the topic and it's still about 4 km/s to reach the orbit. People are working on it, but for what I read it looks hard to overcome for 2030...

You still have to match velocity with the fuel. Crashing into your fueling station at 10000 km/h doesn't help anything.

Actually... it completely solves the problem of the return trip.

Somebody needs to teach NASA to embrace Crash-Only Design.
