Will other planets be colonized by short humans?

I'm reading interesting works sustaining that actually Venus would be quite easy to be transformed in a Earth like planet [and its gravity is really similar, so humans would live very well on it].

But it seems that a giant ocean, with its tide, condemned the planet to its present. Theory proposes that Venus could have been habitable, but a large ocean slowed down its rotation, killing it - Universe Today
Sure ... we cant transform our own deserts, but a whole distant planet.... no problemo..... we got a crew ready

Neither is a viable plan. You take a crew and skeleton admin staff and you bring several thousand embryos and artificial incubators.

I dont understand why we cant preposition equipment and supplies on the target planet... say Mars..... First you send a number of cargo ships that deliver the goods..... in separate but relatively close locations....
Then you send the crew..... even if they miss the exact landing site they should not be too far from one of the prepositionned locations....

All the prepositioned equipment in the world won't help because humans won't survive the trip.

In low gravity humans suffer bone mineralisation. Each month around 1% bone mass is lost and it doesn't grow back when they return to Earth. It takes around nine months to get to Mars so a round trip will cost you 18% PERMANENT bone mass loss. As the bones deteriorate, the calcium ends up in the bloodstream, which causes more medical problems, such as constipation, renal stones, and psychotic depression. In addition your red blood cell count plummets in low gravity causing a range of problems related to anemia.

We won't be surviving a trip to Mars until a ship is developed with a rotating section to simulate gravity. And even then we had better hope that there are no solar flares during that nine month trip.

what about those guys who spent months in a space station ?
