Why is space exploration important
One year ago NASA made there own twin experiment. Scott Kelly was sent to the ISS while his identical twin brother stayed on Earth. About 340 days later Scott comes back to Earth, riding inside the snug soyuz coming back with him is Mikhail Korniyenko. While kelly-the-Earthbound wasn 't really doing anything besides collecting blood, urine, and saliva for research, NASA is also been taking samples from his brother. And by comparing the samples they 'll hopefully know more about what happens to a human 's body in space. One year is twice as long then the normal trip in space, but it is how long astronauts will have to stay in space for interplanetary space to Mars and back. And that 's one year for the …show more content…
To fix that problem NASA makes the ISS astronauts exercise two hours a day , by strapping them to a treadmill with elastic bands or by doing weight resistance exercises. Without gravity the heart shrinks because it no longer has to pump blood to the legs and back. Also the tissue in there head swells or the Charlie Brown effect, It makes it harder to see because there cheeks are swollen. When Scott Kelly touches down on Earth most of the data collecting will be over. But analyzing the data has only just begun.
The dream of space travel, has been humanity 's interest with what’s above the clouds for awhile now. Humans want to explore the unknown, discover new worlds, and push the boundaries of our knowledge. The unreal desire to explore and challenge the boundaries of what mankind knows. Human space exploration gives us the answers to the questions we 've been asking for (dunbar 1).Another reason is obviously curiosity. Who among us has not had the urge to know what’s over the next hill? What child has not been drawn to explore beyond the familiar streets of the neighborhood? Curiosity is a huge reason on why humans even go up in space it 's cause they want to know what 's up there and why it is (Griffin 2). Most people want
