NASA to Launch a Study in 2015 to Identify Effects of Spaceflight on Human Body

NASA is all set to launch a study to figure out how spaceflight would affect human body in 2015. NASA's initiative will get the support from lead participants, veteran astronauts and identical twin brothers Scott and Mark Kelly.

Scot Kelly will be sent to the International Space Station for a one-year mission in March 2015 whereas his twin sibling, retired astronaut Mark Kelly, will remain on earth to be part of the experimental control group.

The aim of the study is to identify any difference in physiologic and mental responses of both the brothers because of space flight and being on earth. Scientists will focus on effects on the human body that are caused by spaceflight and weightlessness.

Mark Kelly is the husband of former Arizona Congresswoman Gabrielle Giffords, and perhaps that is why he is more known than his twin brother Scott Kelly.

Gabrielle Giffords suffered serious injuries during an assassination attempt in January 2011. Mark Kelly retired from NASA and the Navy in 2011 to spend more time with his injured wife.

During the study, frequent blood, saliva, urine, and stool samples will be taken from the 50-year-old twins. Also, there will be regular physiological and psychological tests before, during and after the completion of mission.

The study will mark the stay of Scott Kelly in space as the longest by any American in history. Usually, astronauts are being sent on space missions to the ISS for six months, and it has rarely happened when astronauts have spent a year or longer in space.

Craig Kundrot, Deputy Chief Scientist of NASA's Human Research Programme, said that the study on twin brothers will enable to study the differences that may occur because of living in different environments among two people with the same genetics. In all, both the brothers will participate in 10 different investigations.
