Space travel is one of mankind's greatest achievements of the 20th century. As we explore our universe more and more thoroughly, we face many challenges, but the biggest might be how to adapt to an environment where there is no gravity.
"We put the International Space Station up there to remind ourselves of the fact that we as a species can overcome seemingly insurmountable challenges and that we have the potential to explore space."
"The international space station allowed us, for the first time, to study the biological affects of staying in space for long periods of time and what we found wasn't pretty."
"Astronauts can lose up to 20% of their muscle mass just in first two weeks of being in space."
"We know that we, as a species, will not be satisfied unless we are traveling the stars."
