NASA puts men on Mars for 25 years Stories

Mortal radiation of the cosmos, the potential loss of vision and atrophic bones are just some of the challenges that scientists must overcome before the astronaut can melt Mars, experts and officials from NASA.

The US Space Agency believes that in the next 25 years, a person can be placed on a red planet, but the technological and health challenges that stand in the way of doing this are huge.

"With current budgets or something more, it will take about 25 years to solve these challenges," said the retired astronaut NASA Tom Jones, who traveled into space in various missions.

"We now have to start with some key technologies," he told a press conference in Washington. At a distance of approximately 225 million kilometers, Mars presents a greater challenge than Apollo's mission to the Moon.

With the technology currently available, it would take up to nine months for astronauts Mars, and the physical cost of floating for so long in a zero weight would be enormous. For example, scientists believe that this could lead to irreversible changes in retinal blood vessels, which would lead to visual degradation.

In addition, after the failure of the null weight of the skeleton, the calcium and bone tissue would begin to lose.

Experts are still unaware of the effects of the one-year mission on Earth's surface. Mars.

BETTER PROPULSION
One way to reduce damage to the human body is to significantly reduce travel time to the planet. Jones believes that nuclear power systems would have an added benefit from energy production over the years.

"If we start now, we could have technologies available in 25 years, which will help us protect ourselves from these long travel times," he said.

In today's conditions, only one foot trip to Mars For a long time, the astronaut should use the same amount of radiation that he considers safe in his career.

"We still do not have a security solution in terms of protecting against cosmic rays and sunburns, which are (at the time of transit) exposed (the astronaut)", said Jones.

Experts have identified several technologies that need to be developed rapidly, including a ship that can withstand a sharp Mars and smooth landing and the ability to return passengers to Earth.

The NASA It has a new robotic landing module, called InSight, which goes to Mars, where it will land on November 26 after it flew out of California on May 5th.

The $ 993 million project aims to broaden the knowledge of the situation in the region Mars to send researchers and discover how rocky planets, like Earth, have formed billions of years ago.

Jim Garvin, chief scientist of the Goddard Space Flight Resort NASA, believes that InSight will complete "critical strangers" and help to have a clear understanding of Mars.

In 2020 there will be another mission NASA they will send a vehicle to this planet to find out the living environment of the Martian environment, search for signs of ancient life, and assess the natural resources and threats to future researchers.

In addition, private companies, such as SpaceX and other countries, are developing technologies that could be used in future missions Mars.
