Experiment has never been in space

The US Aeronautics and Space Administration (NASA) is about to perform an unprecedented experiment: sending the children in twins to the International Space Station (ISS) within a year, while the brother is kept on Earth to be the subject of verification.

They will be comparing many characteristics before, during and after completing tasks. The results will help scientists study the effects of space travel on humans and also help uncover the effects of aging in space.

It has long been known that living in long-term space will reduce bone density, reduce muscle mass or atrophy. Until now, scientists also want to know more deeply at the micro level such as considering changes in DNA or aging process . So NASA planned a groundbreaking plan that will take place in March 2015 to study for the first time the impact of space travel on the human body in real time, measuring any changes. between two twins when they happen.

According to the plan, next March NASA astronaut Scott Kelly will work with Cosmonaut's astronaut (Russia) Mikhair Kornienko working on ISS for a year. It is quite interesting for a couple of two astronauts to go to ISS and work together for such a long period of time because it was only 6 months before going and going so far.

However, the period of stay in ISS is not the most important because while Scott flies continuously around the earth at a speed of 27,000 km / hour, the twin brother remains on the ground as a control for the experiment. . Daiy Mail quoted Craig Kundrot working for a human research program at NASA's Johnson Space Center, saying scientists' task is to continuously sample before, during and after the flight. This is the first time NASA can track two genetically identical individuals. NASA has also published 10 proposed criteria for genetic research of twins such as biochemistry, vision, perception .

In theory, the human immune system has made changes in space making it weaker than on the ground. In this experiment, twins Mark and Scott will be given the same flu vaccine and then study how the two's immune system responds.
