Why all the fuss about the launch tomorrow from the Baikour Cosmodrome in Kazakhstan? Expedition 43, also being referred to as the #YearInSpace is a giant step forward for humans one day colonizing other planets and exploring deep space.
This is the first time astronauts will have spent over a year in space and in addition to their regular duties on the ISS, they will be closely studying the effect prolonged space travel has on the human body. The mission will test the physical and psychological health and changes to the crew, and presents a unique opportunity for scientists and flight surgeons since Astronaut Scott Kelly's identical twin Mark will be part of the mission here on Earth. Since they possess the same DNA, seeing changes between Scott and Mark will provide a fascinating and exacting insight as to how space travel changes the body.
And, since we here at Science Channel believe in questioning everything, we wonder if perhaps Mark Kelly, the Earth-bound twin will experience any changes himself since twins have reported sharing the same changes and experiences across long distances?
The International Space Station is in orbit some 240 miles above the Earth, and a year is a long time to participate in this exploration of human endurance. By participating in this crucial mission, these bold adventurers will truly be helping humankind make its first steps towards a greater unknown by testing the limits of what we now know about long term living and exploring space.
