I suppose grandparent comment is saying that a possible timeline is to send some people there today and finish building the rocket to pick them up and bring them back in say 5 years. A bit like the Boeing clusterfuck last year...

It'd also be cool to send an empty rocket with auto-landing capabilities and supplies way before the manned mission, and when those Mars visitors arrive, they can move the tech needed for survival (which would've been invented/improved in-between) to the return rocket.

But that all sounds like Kerbal scenarios rather than real life ones.
