US space agency NASA has launched a ₹20.6 lakh ($30,000) 'Space Poop Challenge' to develop a system that collects and routes human waste away from the body for up to six days, without using hands. The systems should address faecal, urinal and menstrual waste management in a space suit environment while protecting the safety and health of crew members.
