Living in space is no easy task, and one of the largest concerns for mission planners cannot even be seen: cosmic radiation poses a risk to the human body in the form of cancer, central nervous system disorders, cardiovascular problems and tissue degeneration. Our atmosphere protects us on Earth from the constant barrage of cosmic radiation, but venture 50 km up - the International Space Station circles at around 400 km altitude - and the only thing protecting astronauts is the spacecraft hull or their spacesuits. Risk builds over time so we will need to develop ways of counteracting radiation on long missions to far-away planets. The SIS-18 ring accelerator can shoot ions at targets including biological cells, recreating cosmic radiation. Analysing how the ions interact will help mission designers to develop new ways of minimising the risks of cosmic radiation. The ions are accelerated with magnets to 90% of the speed of light, or 270 000 km/s. This image shows a beam diagnosis element, which allows scientists to analyse the shape of the ion beam as it passes through. Credit: ESA / eyevine
