This refers to the news about cosmic rays entering the earth. First, Mars could not emit harmful radiation because it is not a star. Cosmic rays are emitted by stars. i.e bodies that are undergoing nuclear reactions that is fusion (as occurs in our sun) or fission (as occurs in nuclear reactors) . Mars is neither. It is a planet that just reflects sunlight. It cannot emit cosmic radiation.
Next, with regards to these rays the earth’s atmosphere is capable of taking care of them so no need to worry. The magnetosphere absorbs and protects us from the sun’s harmful radiation. Whatever remains is too feeble to affect any thing as far as earth.
The Earth’s magnetosphere prevents most of the particles from the Sun, carried in the solar wind, from hitting the Earth. So why worry?
