Astronauts could be eating their own poop in the not too distant future.
Scientists are trying to find a cheaper alternative to taking food up into space as it's expensive. Disposing of astronauts' waste on long-term space flights is also a problem.
So, it's only natural that poop is turned into food, right? Right?!
Researchers at Pennsylvania State University have developed technology for breaking down solid and liquid human waste, and transforming it into food that’s hygienic and safe for consumption.
Scientists say the concept would be a bit like Marmite or Vegemite, a microbial paste which is high in protein and fat.
Yeah, we're not too sure we'll be becoming astronauts anytime soon!
