NASA wants people on Mars in 25 years



Deadly radiation in the universe, potential loss of vision, and atrophizing bones are just a few of the challenges that astronauts will have to overcome before Mars can foot in the future, experts and senior NASA officials on Tuesday.

The US space agency believes it can put people on the Red Planet in 25 years, but the technological and medical obstacles are enormous.

"The cost of resolving these costs means it will take about 25 years to stay under current budgets or a little enlarged budgets," said Tom Jones, a former NASA astronaut who served as four space shuttles before his retirement in 2001.

"We need to start some important technologies now," he told reporters in Washington.

With an average distance of about 140 million miles (225 million kilometers), Mars creates a greater order of magnitude than anything else that the Apollo missions face.

With today's rocket technology, it would take an astronaut up to nine months to reach Mars – the physical cost of a swim in zero gravity would be great.

Scientists, for example, think that long-term weight loss can cause irreversible changes in blood vessels in the retina, leading to visual impairment.

After a while, the skeleton begins to leak into calcium and bone mass.

With just a third of the Earth's gravity, scientists don't yet know the effects of a one-year mission on the surface of Mars.

– Better drive – a way to reduce wear and tear on the human body shortens travel time to Mars.

Jones asked for nuclear propulsion systems to help generate electricity on flights.

Edi If we start now, within 25 years, these technologies will help us and protect us from these long transitions “, he said.

Under the current circumstances, a trip to Mars would take so long that any astronaut would receive more radiation than usual, which would be considered safe for the entire career.

Is We haven't had a solution to protect you from the cosmic rays and solar flares you've encountered in this transition period, Jones Jones said.

Aviation experts have identified a number of technologies that need rapid development, including a tough entry into Mars and a spacecraft that is soft enough to survive. They could also get people back from the surface and return to Earth.

NASA has a new robotics landing, called InSight zooming towards Mars, as it landed on November 5 after taking off from California on November 5th.

The $ 993 million project aims to expand human knowledge of the interior conditions in Mars, strive to send explorers there, and uncover how many rocky planets have formed billions of years ago, such as the Earth.

Jim Garvin, chief scientist at the NASA Goddard Space Flight Center, said InSight would help fill in “critical unknowns NAS and help create an important understanding of Mars.

Another task in 2020 will see NASA sending a rover to Mars, which aims to determine the viability of the Mars environment, to investigate the old life signs and to assess the natural resources and hazards for future human researchers.

In addition, special firms, such as SpaceX and other nations, are building technologies that can be used in future Mars missions.

Some experts see the new discovery of the Moon as the key to a future mission of Mars, because astronauts can learn to draw water or use technology and apply them to future Mars missions.
