"In building and running the International Space Station, humans have learned how to master space close to Earth. It orbits about 400 kilometres above the Earth, says Parker. “By contrast, the moon orbits 400,000 kilometres distant from the Earth, a thousand times farther away. Mastering a hostile environment that distant will require us overcoming all sorts of technological hurdles. Then we will be better armed when we start looking at Mars, which is 400 million kilometres away – a million times farther from Earth than the space station. This is going to be a long process.”"
Pretty confident of overcoming those hurdles, even if the fuel is our desire to stay away from everyone and their troubles
