Mars Mission Aircraft to Carry Poop Bags to Shield Cosmic Rays -
The journey to Mars is all set to begin in 2018 with two astronauts on 501 days round trip. Countering cosmic rays is a big concern for the Inspiration Mars Foundation team. And to block cosmic rays, the team has found a solution that will see couple astronauts use their own feces.
Taber MacCallum, the Inspiration Mars Foundation's chief technology officer, told New Scientists that poops have great radiation shielding ability and anyways there is no place available for that material to go.
The Mars capsule will be lined with solid and liquid human waste along with food and water to block cosmic rays, he added.
The solid waste will be dehydrated as recycled water will be used for drinking purpose. The dehydrated waste will be kept in the bags to put right against the walls. The drinking water will also be used as shield because nuclei are highly effective to block cosmic rays.
Water has more nuclei-per volume than metal and that is why it’s an effective measure to stay protected from cosmic rays. The waste will line the walls of the craft up to 40 centimeters thick. The trips will, therefore, avoid radiation risks on insemination and child birth of scientists.
