'Can put humans on Mars within 25 years,' claims NASA, but...!

The US space agency has recently claimed that it can put humans on the Red Planet 'Mars' within 25 years. The scientist's' claims there are few hurdles they are facing, if they are not immense, they can be able to put humans on Mars successful.

Deadly radiation from the cosmos, potential vision loss, and atrophying bones are just some of the challenges scientists must overcome before any future astronaut can set foot on Mars, experts and top NASA officials said Tuesday.

NASA believes it can put humans on Mars within 25 years, but the technological and medical hurdles are immense.


"The cost of solving those means that under current budgets, or slightly expanded budgets, it's going to take about 25 years to solve those," said former NASA astronaut Tom Jones, who flew on four space shuttle missions before retiring in 2001.

"We need to get started now on certain key technologies," he told reporters in Washington.

As per reports, at an average distance of about 140 million miles (225 million kilometres), Mars poses scientific hurdles an order of magnitude greater than anything encountered by the Apollo lunar missions.

It would take an astronaut up to nine months to reach Mars with today's rocket technology. For instance, scientists think prolonged weightlessness can cause irreversible changes to blood vessels in the retina, leading to vision degradation, claims media reports.

And after a while in zero-G, the skeleton starts to leach calcium and bone mass. One way to reduce wear and tear on the human body is to dramatically cut down on travel time to Mars, said Jones.

Jones called for nuclear propulsion systems that would have the added benefit of producing electricity on flights.

"If we start now, in 25 years we might have these technologies available to help us and protect us from these long transit times," he said.
