It's Time for Sustainable Development Goal for Space

In 2015, the United Nations adopted the 2030 Agenda for Sustainable Development—the Sustainable Development Goals (SDGs)—a universal call to action to protect the planet for future generations and ensure that all people will enjoy peace and prosperity. These 17 goals included the elimination of poverty, hunger, and inequalities, the promotion of education, and the promotion of sustainable development worldwide. With the rapid development in Low Earth Orbit (LEO), there are growing concerns that an 18th SDG should be adopted for space.

This goal calls for the sustainable use of Earth’s orbit by space agencies and commercial industry and the prevention of the accumulation of space junk. This has become a growing problem in recent years thanks to the deployment of satellite mega-constellations and the “commercialization of LEO.” In a recent study led by the University of Plymouth, a team of experts outlined how the lessons learned from marine debris mitigation could be applied to space so that future generations can live in a world where space truly is “for all humanity.”

Cultured Meat Could Keep Astronauts fed in Space

The term “cultured meat” has become a bit of a buzzword for the health food industry. This refers to meat produced in a lab using in vitro cell cultures derived from animal proteins. For many, this “alternative meat” is vital to combatting climate change by removing one of the chief causes of deforestation (making room for cattle ranches) and global warming (bovine methane emissions). For others, it’s an environmentally-friendly way of ensuring food security in an era of climate change.

But what about as a means of feeding astronauts on long-duration missions or living for extended periods beyond Earth? In this case, cultured meat would be a way of fulfilling the dietary needs of astronauts who would otherwise be entirely dependent on vegetable proteins. The possibility is currently being explored by the European Space Agency (ESA) and could be a game-changer for future missions to the Moon, Mars, and beyond!
