Human missions to Mars in doubt after astronaut kidney shrinkage revealed
‘An astronaut could make it to Mars but they might need dialysis on the way back,’ scientist warns
Scientists at University College London (UCL), who carried out the study, said that serious health risks are more likely to emerge the longer that an astronaut is exposed to the extreme conditions of space. “We know what has happened to astronauts on the relatively short space missions conducted so far, in terms of an increase in health issues such as kidney stones,” said Dr Keith Siew, first author of the study from the London Tubular Centre, based at the UCL Department of Renal Medicine. “You can’t protect them from galactic radiation using shielding, but as we learn more about renal biology it may be possible to develop technological or pharmaceutical measures to facilitate extended space travel.”
