Deadly radiation from the cosmos, potential vision loss and atrophying legs are just some of the challenges that researchers must overcome before a future astronaut can put foot on Mars, experts and top Nasa officials said Tuesday.

The US Space Agency believes it can put people on the red planet within 25 years, but the technical and medical obstacles are huge.

“The cost of solving them means that under the current budgets or slightly expanded budgets will take about 25 years to solve them,” said former Nasa astronaut Tom Jones, who flew on four space mission missions before joining pension 2001.

“We must get started now with some important technologies,” he told reporters in Washington. 19659006] At an average distance of approximately 140 million miles (225 million kilometers), Mars’s scientific problems represent an order of magnitude greater than that of Apollo Lunar missions.

With today’s rocket technology gy, it would take an astronaut up to nine months to reach Mars – the physical pathway for floating as long in zero gravity would be huge.

For example, scientists believe that prolonged weightlessness can cause irreversible changes in the blood vessels in the retina,

And after a while at zero G, the skeleton begins to leak calcium and bone mass.

With gravity only one third of the earth, scientists do not yet know the effects of a supposed one.

Better propulsion

One way to reduce the wear of the human body is to dramatically cut down on travel time to Mars .

Jones is called nuclear power plants that would have the added benefit of producing electricity on airplanes.

“If we start now, in 25 years, we can get this technology available to help us and protect us from these long transit times,” he said.

Under current conditions, only one outgoing trip to Mars would take so long that any astronaut would receive the same amount of radiation that would normally be considered safe for a whole career.

“We do not have the solution yet in terms of foreclosure, in terms of protecting you from cosmic rays and sunspots that you experience during this transit time,” Jones says.

Experts in the aviation industry have identified several technologies that require rapid development, including spacecraft that can survive the hard entry into Mars and land soft enough, as well as the ability to lift people from the surface and return to the ground.

NASA currently has a new robotic landlord called InSight zooming toward Mars due to land it November 26, after leaving from California on May 5.

The US $ 993 million project aims to expand human knowledge of internal conditions on Mars, inform efforts to send investigators there and reveal how rocky planets the Earth formed billions of years

Jim Garvin, chief researcher at NASA Goddard Space Flight Center, said InSight would fill in “critical ignorance then “and help build an important understanding of Mars.

2020 comes another mission to see NASA send a rover to Mars aimed at determining the Martian environment, searching for signs of old life and assessing natural resources and dangers for future human explorers.

In addition, private companies like SpaceX and a host of other nation building technologies build on future Mars missions.

Some experts see new moon exploration as the key to a future mission to Mars, as astronauts can learn about extracting water or using technology and applying these lessons to future Mars missions. [19659024] window.fbAsyncInit = function () {
