The National Aeronautics and Space Administration (NASA) has indicated through the intermediary of its scientists that, in the next 25 years, the man could land on Mars.
However, the gulf that exists to achieve such a feat is great, because they will before they overcome the technological and medical obstacles that this dangerous journey represents for a human being.
Possibility of loss of vision, deadly radiation The cosmos and atrophied bones are among the challenges that men of science will face.
"With the current budgets or even more, it will take about 25 years to solve these problems," said NASA astronaut Tom. Jones, who has experience in space travel.
In addition, at a press conference in Washington said: "We must start with some key technologies" –
It should be noted that with According to the current technology it would take an astronaut nearly nine months to reach Mars, in addition to the excessive physical cost of so long floating in weightlessness.
This could lead to irreversible changes in the blood vessels. of the retina, which would lead to a deterioration of vision. Without neglecting this, the fact that the skeleton begins to lose bone tissue and calcium for so long in weightlessness
could stop being a problem if travel time was reduced. Jones believes that for this to become a reality, you have to work on nuclear propulsion systems.
"If we start now, in 25 years, we may have technologies to protect us from these long travel times," he said. ] The experts agree that many technologies need to be developed quickly, including a ship capable of withstanding the difficult entry of Mars and a soft landing. , as well as the function of bringing pbadengers back to Earth.
