The structure and function of the kidneys is altered by space flight, with galactic radiation causing permanent damage that would jeopardise any mission to Mars, according to a new study led by researchers from UCL.
The volume of shielding water needed is the difference between those two cylinders, or 22⋅π⋅2.752−20⋅π⋅1.752≈522.68−192.42=330.26m3. As one cubic meter of water weighs 1 metric ton (1,000kg), that’s 330,260kg to get into space
Honestly, 330 tonnes doesn’t seem too unacheivable to me. That’s less than the mass of the ISS, which was built using much smaller rockets than are currently in development.
