How bad is the radiation on Mars? Missions to Mars may seem like a long way away. NASA currently has their eyes set to get humans us around the mid to late 2030s. But in reality, this time scale is very small because of some hurdles to overcome first. The most dangerous truth is being exposed to high radiations in space.
When it comes to the planet Mars there are many things we don’t know about it as a whole. Its history is very much a riddle in every aspect and we don’t know what lies beneath its surface.
We don’t know if we can make a colony there but of course, being human we are going to try which is noble. But also problematic for a very basic reason. Mainly we have to fight a lot of things to get us to not just live on Mars but survive there too.
We already know some of the basic dangers while living on Mars, such as not having a supply of food and water. Secondly no oxygen because of the atmosphere we don’t have natural oxygen that we can breathe. We would need spacesuits to make sure the pressures of space would not crush us.
The main culprit for the dangerous radiation in our solar system is the sun. It is constantly emitting light in many different frequencies and has a steady outflow solar wind. Which is highly energized protons electrons and alpha particles, in other words, subatomic particles? These cuts those wavelengths can be dangerous to humans as it is.
Radiation On Mars
However, most people don’t know about it that Mars is the planet infamous for its Radiation. The reason is a very thin atmosphere and the lack of magnetosphere.
Mars is constantly bombarded with High radiations and with high radiation a human can’t live and survive.
The question arises why Mars doesn’t have protection against radiation.
Mars has no protective magnetosphere as the earth does. Scientists believe that at one time Mars also experienced convection currents in its core. Creating a Dynamo affected power to a planetary magnetic field.
This lines up with many signs from Mars that at one point in time. It may have been very much like earth including having oceans of water and possibly even fields of grass or other things.
The question is how did we learn about all the problems Mars has with its atmosphere and its radiation. The answer is simple we sent probes in crowds to find it out, with this process we learn what could we do in the future.
Roughly 4.2 billion years ago either due to a massive impact from a large object or rapid cooling in its core this Dynamo effect ceased.
As a result over the next five hundred million years. Mars’s atmosphere was slowly stripped away by solar winds between the losses of its magnetic field.
Its atmosphere and the surface is exposed to high radiation than our earth. And in addition to regular exposure to cosmic rays and solar wind, it receives occasional lethal blast that occurred with strong solar flares.
Why Earth is Safe from Radiation?
Earth is safe from high radiations because of the magnetosphere and the atmosphere that lies above our planet. Between the two we have a shield that will deflect the most harmful radiation but on Mars.
We wouldn’t have that shield or safety net. We would get the full-on radiation from both the sun and other resources from space. Which is why the red planet is a baked red badland with nothing living on it.
But then how do we get the radiation down to those safe levels, so assuming we can get to Mars and we can put people on it how would we protect ourselves from the radiation?
By the 2030s technology will have advanced enough for this to become a real possibility. So let’s see the astronauts have arrived on Mars.
