Презентация на тему A trip to Mars

to Mars with a manned spacecraft.

Mars in order to colonize the planet. The project

was developed in 2010. The main idea of the project is to send people to Mars forever. This will significantly reduce the cost of the flight, it will be possible to take more cargo and crew. First 'Martians' plan to send to the Red Planet in 2030 already.

delivered with high-tech equipment and a small nuclear reactor

can produce oxygen, water and food. Every two years, when Mars will be provided at the desired orbit, NASA will be able to replenish stocks of "colonists" and deliver new astronauts.

the main purpose of flight to Mars - landing

several people on the surface of Mars, with the return to Earth, as the objectives of the mission belongs to search for resources outside of the Earth.

DNA of the organism. Of the damage is irreversible

and can lead to cell mutations.
Prolonged weightlessness during space flight is just the greatest medical problem. Muscles, bones and the circulatory system due to missing gravity become weak if they are not trained.

his body begins to change. Blood flows to the

upper half of the body, and the heart has to do more to pump blood. The body "thinks" that a lot of fluids in the body and begins to secrete hormones that are responsible for water-salt metabolism, resulting in a person loses a lot of fluids. Usually astronaut during this restructuring requires at least 3 liters of water a day. This effect is quite fast

tangible for the cosmonauts. Most often cited aggression, which leads

to conflict when people are long in a confined space. This effect can be minimized if the stress-type people in interplanetary crew.

rocket motor. Each engine has its tanks with a

working medium, its control system, its own section of the solar panels. If we consider that electrorocket engines have high reliability, the failure of a number of motors not much effect on the duration of the flight.

which a few days provide increased dose crew. In

such cases, the astronauts take cover and protected from ionizing radiation, a special room. Possible violations of health technology, especially computers, and wired communications during this time should be emphasized.

astronauts when hit by light. Due to the very

small particle size of it is very difficult to isolate. So the astronauts of the "Apollo" on the next day noticed the presence of dust in the descent module.
