Diligent in study of the world of view of scientific forward position is reasonable eaves of hole extensive region
Is aerospace the mankind to " escape be born day " hope or " beyond redemption " Tartarean? According to a of NASA newest investigation and study shows, in airship of Fan Zaiyu time or the astronaut that dimensional station has worked, the herpes virus that the conceal inside the astronaut system that exceeds half the number wears is activationed afresh. Without doubt, such phenomenon explored the task to cheat a shadow for prospective deep space, let a person must reconsider the mankind entering the feasibility of aerospace.
On recent press conference, heart city restricts center of writing abdicate spaceflight (Johnson Space Center) scientist Satish Mehta expresses, after astronaut enters outer space, the such as inside body is coriaceous alcohol and adrenalin such answering stimulate hormone to meet a large number of exudation, bring about the fall of function of system of human body immunity directly. Meanwhile, the aerospace that because be in small gravitational environment personally,the function of cell of the immunity inside astronaut body meets (after 60 days) and be weakened considerably, especially those have the immune cell that restrain and eliminates virus function.
Mehta and its work in the same placing return unexpected ground discovery, there are 47 people in 89 astronaut that execute short-term mission (53% ) when the herpes virus in uric fluid and saliva compares them to be on the earth, get more much! And in 23 astronaut that executing long-term space mission, unusual number amounts to 14 people (61% ) . Apparent, after aerospace lives, the virus that dormancy condition is in originally inside human body is activationed afresh, this lets researcher begin to suspect, the culprit with minatory healthy astronaut is environmental pressure.
The scientist expresses, the astronaut that has a symptom at present fortunately is opposite less, what participating this research is all in 89 astronaut, only 6 people suffer from in aerospace went up bleb, 7% what hold total number about. But as a whole, astronaut leaves earthly time to grow more, the risk of their sicken and odds are bigger also. Accordingly, NASA fears this problem is met executive spark of block up future lands the job. After all, the life safety of astronaut is Chongzhongzhi is weighed.
Long-term since, the astronaut of NASA bears week of a move in chess or a movement in wushu, be as long as even the cosmic radiant influence of a few months, get used to the environment of small gravity hard even. Not only such, of cycle of the psychological pressure that keeps apart with the world, Morpheus always also affecting astronaut mussily, create huge burden to its.
? In recent years, the small gravitational environment that all indicates aerospace in the light of the multinomial research of astronaut and cosmic ray can cause not reversible loss to human body, can change the DNA of a few important cells inside human body even, this cheated a shadow to space exploration undoubtedly, to astronaut people healthy problem constitutes great menace.
