Mars: NASA measures radiation – gives details

Radiation on Mars is deadly to humans. But now there are new details that give hope — thanks to NASA’s Curiosity spacecraft.

Frankfurt – Mars* As a planet next to Earth, it exerts great magic on humanity. In the 1930s, the US space agency wants to NASA* For the first time, an astronaut has been sent to the Red Planet – but one point remains to be resolved: radiation protection for space travelers: Inside.

Since Mars, unlike Earth, has neither a protective magnetic field nor a dense atmosphere, radiation from space can penetrate the surface of the planet unhindered. NASA’s rover, which is currently conducting research there, is not interested in radiation – but it could be fatal to humans.

Radiation on Mars: Some terrain formations can protect people

Therefore, people who are supposed to explore Mars in the future need radiation protection – and it is better that they do not have to travel long distances from Earth to the Red Planet. The rover Curiosity, which recently discovered a “strange structure” on Mars, appears to have now found a solution to this fundamental problem. That’s what has been suggested at least by a study published in Geophysical Research Letters that is based on data from the NASA Curiosity spacecraft.

The study by lead author Guo Jingnan (University of Science and Technology in China) and an international research team is working with data from the Radiological Assessment Detector (RAD) instrument on board the Mars rover. It measures harmful radiation on Mars – regardless of whether it comes from the Sun or from other sources. The area that RAD can measure in detail is named after NASA Murray Bates Receipt. ‘Curiosity’ has been parked in this area for 13 days – while the RAD tool continues to collect data. According to the study, these data show a decrease in radiation.

Near the Murray Pots (butt is translated from English as “hardness” – it’s a rock more resistant than the surrounding area and therefore less eroded) the amount of radiation decreased by about five percent. Now five percent isn’t much – but any reduction in radiation helps in a challenging environment like Mars.

Mars: Any amount of radiation protection, no matter how small, helps with space travel

There are two types of radiation on Mars: direct radiation that comes from above, that is, from the sun or from space. and indirect radiation that is reflected off the surface of Mars. When it comes to indirect radiation, the RAD data also shows something that should be important for future human research on Mars: features of the Martian surface that future astronauts can protect from direct radiation can simultaneously amplify indirect radiation. So it is not enough to look for hardy and shelter there – indirect radiation can be increased there.

The new study does not facilitate understanding of radiation conditions on Mars. In addition to conditions that can change the radiation, there is also the distance between Mars and the Sun. It seems that things as unimportant as the height a person is on Mars or the angle at which radiation penetrates through Mars’ thin atmosphere can also make a difference.

Although the study does not offer a definitive solution to the problem of radiation on Mars, it does provide other methods such as space travel* May work in the future. Any natural radiation protection on Mars will likely be used in future space navigation missions, or as Universe Today puts it: “Detailed radiation maps that also include terrain could save lives.”
