It's said that what's so amazing about spaceflight is that how fast man has accomplished it. It took less than 60 years from the time that the Wright Brothers stretched their wings at Kitty Hawk to when Yuri Gregarin became the first man to orbit the earth. Less than nine years after that, Neil Armstrong to that one small step, putting man on the moon by the end of the decade. Since then, manned space flight has be confined to low earth orbit, but man has reached far outside it's solar system with various unmanned probes which have reached the boundaries of interstellar space. So what is spaceflight, how risky is it and is it worth the billions spent every year by taxpayers? This SlashGear 101 will answer some of those questions.
