Mars | NASA scientists have bet for 25 years to bring a man to Mars.


Desperate radiation from the universe, loss of vision and bruised bone are just a few challenges scientists must overcome before astronauts can go Mars, Experts and civil servants NASA.

The US space agency believes that a man can fall on a red planet in the next 25 years, but the technical difficulties and medical challenges that can occur are enormous.

"With current budgets or more, it will take about 25 years to solve those challenges."NASA astronaut Tom Jones performed various missions while flying.

"We have to start with certain core technologies," he told reporters in Washington.

The red planet, at a distance of about 225 million kilometers, is a bigger challenge than Apollo to the Moon. Currently available technology, Astronauts will take up to nine months to arrive at Mars, and the physical cost of so long floating in zero gravity will be tremendous..

Scientists, for example, think that this can cause irreversible changes in the blood vessels of the retina, resulting in decreased vision. Also, under zero gravity, the skeleton will begin to lose calcium and bone tissue.

Experts still do not know the impact of the one-year mission on the surface of the earth. Mars.

Better thrust

One way to reduce the damage to the human body is to significantly reduce the travel time to the planet.

Jones believes the nuclear propulsion system has the added benefit of producing energy in flight. "If we start now, 25 years from now, we will be able to take advantage of technology to protect us from these long journeys.

In today's situation, one leg of a trip to Mars will take too long. The astronaut receives the same amount of radiation that he believes is safe in his career.

"There is still no safety solution in terms of protection of the spacecraft and astronauts exposed to solar flares during this transit time," Jones said.

Experts have identified several technologies that need to be developed quickly, including ships that need to make haste. Mars And make the landing smooth, passengers Earth.


That NASA It has a new robotic landing module called InSight and will land on 26th of November after taking off from California on May 5th on Mars.

Jim Garvin, chief scientist at NASA's Goddard Space Flight Center, believes that InSight completes "the things of the critical illusion" and helps clear understanding of Mars.

In 2020, other NASA missionaries will determine the residence of the Mars environment, find signs of ancient life, and send vehicles to the planet to assess the natural resources and risks of future human explorers.

In addition, private companies such as SpaceX and other countries are developing technologies that can be used for future missions to Mars. (AFP)
