Difficult to travel to the stars

It is difficult to build a spacecraft capable of going to some distant planet, but it is even more difficult to maintain life for astronauts throughout the journey.

>>>America dreams about the journey to the stars

Journey to the nearest stars The solar system takes several decades to several hundred years, experiencing at least several generations of astronauts. But scientists are still unclear whether humans can give birth safely in space.'Determination of gravity intervention to conception rate and successful pregnancy , ' said Dan Buckland of the Massachusetts Institute of Technology at the 100-year Airship Symposium, led by the Research Foundation. Modern Defense Project (DARPA) - US funded.

So far, people have not yet launched the spacecraft out of the Solar System, let alone the nearest star more than 4 light years away. A light-year - the distance of light travel for 1 year - is determined to be about 10 trillion km. It is still not possible to find a spacecraft that could be a good example in this case, since the spacecraft that once carried the moon to Apollo 10 operated more than 40 years ago, can fly at nearly 40,000 km / hour. With such a distance, future spacecraft must maintain their own operation, which science has not yet implemented. Besides, unless the scientists find a way to recreate the gravitational environment on the spacecraft, a interstellar journey will be forced into zero gravity. Over time, this condition will destroy the human body, cause muscle atrophy, destroy minerals in bones and weaken vision, according to biologist Athena Andreadis of the University of Massachusetts.

The effect of the gravitylessness on the developing fetus is even worse, more likely to disrupt the normal development of the fetus, and affect nerve function. Your child's body and skeleton can develop differently in space than babies on the ground. That's not to mention the time of flowering, it is predicted to be extremely terrible without the support of gravity, as said by Andreadis expert with SPACE.com . However, before this scenario occurs, the affair on the spaceship will be extremely hard. According to Andreadis, due to the absence of traction, the pair of partners are more likely to have to constantly collide with the spacecraft, without friction, with no fulcrum and everything slippery.

Assuming all the obstacles are overcome and our astronauts reach their destination, the difficulty is not over. Even when the spacecraft landed on a planet with life, the environment here may not be similar to the earth. The next job is to build the biosphere, and this can affect the life of the organisms there. Another option is to create people who can tolerate new environments. But the creation of a different type of citizen with earth people will face moral problems, not to mention biological difficulties.
