How bad is the radiation on Mars?

The video discusses NASA's plans to send humans to Mars by the 2030s and the significant challenge of space radiation. It explains different types of radiation, including solar flares, coronal mass ejections, and galactic cosmic rays, and their potential harm to astronauts. Earth's natural protections, such as its magnetic field and atmosphere, are highlighted. The video explores various methods to protect astronauts, including spacecraft shielding, hydrogenated materials, and potential Mars habitats. It concludes with a discussion on the future of space exploration and the need for further technological advancements to mitigate radiation risks.
