Build space toilets: Astronaut Prasanth Nair to Indian startups

Indian Astronaut Group Captain Prasanth Nair urged startups to explore unconventional areas. "Start making space toilets because there is only one successful space toilet in the world," Nair said. "Russia is the only country in the world that has an effective space toilet in place. Even Americans had to depend on Russian technology on the International Space Station," he added.
