Mission to Mars

A person is attracted to space. He wants to figure out where it came from, if not from monkeys, and is there intelligent life on other worlds. And don’t always need to look prohibitively far away, if you planet “on all occasions”. Mars became the object of attention long before the exploration of space, and it is popular with filmmakers who want to make fiction.

But it was a fantastic part of the question this film will have problems. The Director was not able to find and catch the right rhythm and the right mood. The trouble is in the details. It begins with the earthly scenes where the astronauts rolled up a party on the occasion of the mission. Then the viewer is immediately thrown on the surface of Mars, where already carried out some work. Even really clear what they’re looking for. In movies about space and traveling through it is always interesting to watch the preparation. As the astronauts enter the ship, as the ship takes off, passes the atmosphere, overcomes a great distance, and were approaching their destination. Well and then — as scientists begin their work, take their first steps in uncharted territory, etc. Continue reading

Space flights cause a failure in the immune system of a person

The results of two studies of NASA, recently published in the journal journal of Interferon & Cytokine Research suggest that spaceflight may cause temporary changes in the immune system of crew members who are long time on Board the International Space Station.

Data obtained at an early stage of one of the experiments showed that the distribution of immune cells in the blood of crew members during the flight remained relatively unchanged. However, they found that some cell functions were significantly reduced, while the activity of another cell type, on the contrary, increased. That is, in a sense, the immune system of crew members, it failed.

If the cell activity is suppressed, the immune system cannot adequately react to threats, which can lead to asymptomatic for the virus. If activity is increased, the immune system becomes too sensitive, which can lead to the development of allergic reactions and persistent rashes, as well as reported some of the crew members.

In another study, scientists analyzed blood plasma, measuring the concentration of cytokines – proteins that regulate the immune system. Continue reading

Do I need to be perfectly healthy to fly in space?

The main problems during space flight are considered motion sickness, fatigue, dehydration, loss of appetite and back pain

The astronauts can perform on the International space station not more than six months. And for good reason.

The loss of muscle and bone mass in zero gravity during this time is so great that the continued presence in space for humans is not possible.

Future space tourists will not go through the same tough training as cosmonauts and astronauts – how flying can affect their health?

In an article published by the British medical journal, argues that the district doctors in British clinics need to be prepared for the fact that in the near future, their patients will begin to wonder whether their body to move space travel.

Only a handful of doctors have sufficient knowledge in the field of space medicine to give expert advice. Continue reading
