NASA wants people in Mars within 25 years.



The bones that prevent Cosmos's deadly radiation, sight loss, and decline are just some of the challenges that scientists have to overcome before they hit Mars. NASA officials told Mars on Tuesday.

The US space agency believes that humans can be buried in the red earth within 25 years, but the technical and medical obstacles are enormous.

Tom Jones, a former NASA astronaut, was known to have performed four space shuttle missions before retiring in 2001. "The cost of salvaging an astronaut will take about 25 years if we increase our current budget or budget a little.

He told Washington reporters: "We have to embark on certain core technologies.

At an average distance of about 225 million kilometers, Mars raises a bigger scientific question than it would face on the Apollo moon.

Using today's rocket technology requires up to nine months of astronauts to reach Mars.

For example, scientists think that extended weightlessness can cause irreversible changes in the blood vessels of the retina, resulting in decreased vision.

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

With just one third of the Earth 's gravity, scientists do not yet know the impact of the estimated one – year mission on the surface of Mars.

Better thrust

One way to reduce human wear is to drastically reduce your travel time on Mars.

Jones has demanded a nuclear propulsion system with the added benefit of producing electricity during flight.

"If we start now, within 25 years, these technologies will help us and protect us from these long travel times," he said.

In the present situation, the outward journey to Mars will take a long time and astronauts will receive the same amount of radiation as they normally think to be safe over their entire career.

"We still have no solution in terms of shielding you in terms of protecting you from spaceships and sunburst," Johns said.

Aerospace experts have identified several technologies that require rapid development, including the ability to withstand harsh penetrations on Mars, smooth-landing spaceships, and the ability to lift people from the surface to the earth.

NASA has a new robotic lander named InSight that will expand to Mars on May 26th after taking off from California on May 5th and landing on November 26th.

The 993m project aims to expand human knowledge of the internal conditions of Mars and inform efforts to dispatch explorers and to reveal how Earth-like rock planets were formed billions of years ago.

Jim Garvin, Chief Scientist at the NASA Goddard Space Flight Center, said that InSight will "fill critical and unknown" and help a major understanding of Mars.

Another mission in 2020 is to send Mars rovers to Mars, determine the residence of the Mars environment, find signs of ancient life, and evaluate natural resources and risks to future human explorers.

In addition, private companies such as SpaceX and many other countries are developing technologies that can be used for future Mars exploration.

Some experts believe that a new exploration of the moon is the key to Mars's future mission, because astronauts can extract water or apply technology to future Mars probes.
