Space elevators in New Science mag
31st August 2006
New Science has an article on elevators to outer space, but you have to pay to read the whole thing:
If you can make it into low-Earth orbit - about 160 kilometres up - then you are halfway to anywhere in the solar system. Sci-fi writer Robert Heinlein’s remark has become a mantra in the space community, mainly for its irony: despite leaps in rocket technology costing billions of dollars, those first 160 kilometres are still the hardest.
