Cosmic kidney disease: the condition that could affect Mars missions

Deep space missions

New research has shown a possible deterrent to future deep space exploration missions: the effects of these endeavors on astronauts’ health.

Unexplored consequences

The study, published in Nature, explored the consequences of space travel on the kidneys. It said that the effects of space on vital organs are mainly unexplored.

Microgravity and GCR

The researchers focused on the effects of microgravity and Galactic Cosmic Radiation (GCR) on the kidneys during prolonged space travel.

Kidney failure

Newsweek reported that, according to the study, a long trip, like the two-year trip NASA astronauts might take to Mars, could cause the crew kidney failure.

Observation

The team observed rats exposed to conditions similar to those in deep space, such as the one outside the Earth’s magnetic field. It also monitored humans who had traveled to space.

Hard to detect

One of the study’s authors, Keith Siew, warned that some astronauts might need dialysis after returning from a space trip like that. He also said radiation damage is hard to spot, and it could cost lives during the journey.

Kidney stones

The result did not blindside the team. Siew said in a statement cited by Newsweek that science has known that space travel can affect astronauts’ health and cause kidney stones.

Missions in danger

Those health issues “would be catastrophic for the mission’s chances of success,” Siew concluded. It could endanger missions, as NASA plans to go to the red planet in the next decade.

A window of opportunity

University College London professor and other author Stephen B. Walsh said in a statement that the study showed that kidneys are an essential organ to look into for space travel.

Medical solutions

“It may be possible to develop technological or pharmaceutical measures to facilitate extended space travel,” Walsh added in the UCL statement.

Benefits for all

The professor also said that pharmaceuticals that help astronauts’ kidneys tolerate radiation better could also help on Earth. For example, the medicine could help cancer patients receive higher radiation doses.

Mars 2030

NASA expects to send a mission to the red planet in the 2030s. To achieve that, the agency is also studying how such a mission could affect the crew’s mind and body.
