NASA is Teaching Us Sustainability
“Astronauts who spend months on end in orbit have to learn to make do and mend in the best tradition of sustainability. Missions to bring fresh supplies are expensive and time consuming. For any astronauts who take on a mission to Mars, planned for the 2030s, with the round trip likely to take two years, life would be even tougher.
That prospect has helped focus minds at America’s space agency, Nasa, on clever ways to provide for daily needs in challenging conditions. But the lessons being learned are also proving to have knock-on benefits down here on Earth.”
