A vest designed to shield astronauts from deadly solar particles in deep space is set for trials on a lunar mission ready for deployment on any manned mission to Mars, its Israeli developers said.The AstroRad Radiation Shield has been devised by Tel Aviv-based StemRad, which has already produced and marketed a belt to protect rescue workers from harmful gamma ray radiation emitted in nuclear disasters, such as Chernobyl and Fukushima.The vest will protect vital human tissue, particularly stem cells, which could be devastated by solar radiation in deep space or on Mars, whose sparse atmosphere offers no protection, StemRad's CEO Oren Milstein said.U.S. space agency NASA has said it hopes to send astronauts to Mars in the mid-2030s.The vest is made of layers that look like a contoured map and will be tailor-made for each astronaut. Non-metallic protective materials will be positioned on each shield to cover the organs of each astronaut.
It's what I thought, there's no vital human tissue in their noggins. No need to protect them from evil solar radiations. So just a vest will do.
