Human missions to Mars in doubt after astronaut kidney shrinkage revealed

Human missions to Mars could be at risk after new research revealed that long-duration space travel can impact the structure of astronauts’ kidneys. Samples from more than 40 space missions involving humans and mice revealed that kidneys are remodelled by the conditions in space, with certain parts showing signs of shrinkage after less than a month in space. The findings could jeopardise plans by SpaceX and Nasa to send crewed missions to Mars in the coming decades, with SpaceX boss Elon Musk recently claiming that it could be possible within the next “10 to 20 years”. SpaceX created a five minute animation demonstrating what a crewed trip to Mars aboard a Starship rocket might look like (SpaceX) Scientists at University College London (UCL), who carried out the study, said that microgravity and galactic radiation from space flight caused serious health risks to emerge the longer a person is exposed to it. Future missions to Mars were not ruled out, though the scientists said that measures to protect the kidneys would need to be developed to …
