Scientists say the best time for humans to travel to Mars is when the sun is roaring

This story is part of Welcome to Mars, our series exploring the red planet.

Humanity relies on the idea of ​​visiting Mars in person, but there is a nagging problem of dangerous radiation during long spaceflights to get there. Scientists have raised concerns about brain damageAnd Digestive problems Cancer is on a journey to the red planet. In general, it sounds disgusting, but it is not impossible to withdraw.

A new study has some suggestions for dealing with safety issues, which could partly be due to strategically choosing the best time to travel.

“This study shows that while space radiation imposes severe limitations and poses technological difficulties for the human mission to Mars, such a mission is still viable,” the paper says. Published this month in Space Weather. It covers simulations that indicate the optimal time to travel to Mars.

The paper calls out two main types of hazardous particle radiation: solar energy particles (SEP) from our sun and galactic cosmic rays (GCR) from outside the solar system. Researchers point to a time known as solar maximum — when our sun is at its highest level of activity — as an ideal time for humans to head to Mars.

“Scientists’ calculations show that it will be possible to protect a spacecraft associated with Mars from energetic particles from the Sun, because during the solar maximum, the most dangerous particles and their energy are deflected from distant galaxies due to enhanced solar activity,” UCLA said in a statement on Wednesday.

Spacecraft designers will need to focus on protecting astronauts from SEP, but there will be less impact from damaging the GCR during the solar maximum. The team also recommends maintaining a round-trip to Mars for less than four years, although the study acknowledges that this may change based on the development of new shielding materials.

Travel time to Mars can vary (NASA’s Perseverance mission took about seven months to get there), but there are several peak times coming in the mid-1930s and 2050 when shorter journeys from Earth to Mars coincide with periods. of maximum solar energy. We hope this helps you plan your vacation on Mars.
