Hardly a week goes by without some news item about Mars and the
likelihood of manned flight to it.

I ask, where is there a cape Canaveral launch facility on the red planet
it in order to facilitate a return journey to Earth. Because that's what would be needed
given a not dissimilar gravity of the two planets.

We are all aware what is need to launch a human into space from earth.
It simply cannot be done with the crafts that took off from the moon. Similarly
such a craft would not be powerful enough to escape the gravity of Mars.

Those people who enthuse about manned spaceflight to mars (curiously
enough) never seem to mention this basic problem.
