The frame: the film “the Martian”
Scientists at the University of new Hampshire in US found that the effects of radiation on astronauts making space travel more seriously than was considered earlier. The reason for this is the decrease in solar activity, with the result that the solar wind effectively reflects less cosmic rays. About it reported in a press release on Phys.org.
The researchers analyzed data from CRaTER instrument located aboard the automatic station Lunar Reconnaissance Orbiter and is designed to assess the harmful effects of cosmic rays and solar radiation. It turned out that the radiation sources which are objects outside the Solar system, becomes more intense. The reason for this is the anomalous long period of low solar activity.
According to scientists, the possible radiation dose that will be received by the astronauts who went to Mars, will increase by 30 percent. However, the danger comes from the Sun. So, in September 2017, astronomers have recorded a coronal mass ejection, which led to the emission of energetic particles.
