The data from these studies helps scientists comprehend whether cosmic dark matter and antimatter exist in huge amounts in the cosmos, as well as the genesis and spread of cosmic ray particles in our Milky Way galaxy. These findings may also aid scientists in better understanding the radiation hazards associated with future crew trips to the Moon and Mars, as some cosmic rays can be detrimental to humans.
