Why can鈥檛 humans go to space?
The distances involved, the demands it would put on the human body, and the cost of any hypothetical manned spacecraft are all formidable challenges. Each of these 鈥?and other problems 鈥?must be solved, or else manned interstellar travel will remain impossible. Distances in space are vast.
What are the problems of space travel?
The second set of problems are biological ones. Space travel is not kind to the human body. This is true even close to the Earth, where astronauts are at greater risk of radiation exposure as well as the effects of prolonged time in weightlessness (causing muscular atrophy).
How hard is it to slow down a spacecraft?
How easy that is to do depends on the spacecraft. If it is a heavy one like the Space Shuttle (now retired of course) then it can only slow down deep in the upper atmosphere, where it is dense. So it gets very hot. That鈥檚 why the Space Shuttle had to have ceramic tiles able to withstand temperatures up to 3,000 F (1,650 C).
How difficult is it to travel to the Moon and Mars?
The problem is equivalent to that faced in travelling to the Moon and Mars, except on a far grander scale: manned spacecraft must be orders of magnitude larger and more complex, since they must contain all of the apparatus and space necessary for humans to survive inside them.
