In the coming years, NASA will be making the long-awaited return to the Moon, where they will be joined by multiple space agencies and commercial partners. This will be followed by NASA and China sending the first crewed missions to Mars and other locations in deep space in the next decade. This presents numerous challenges, not the least of which involves providing for astronauts’ basic needs while in flight. In keeping with Dr. Sian Proctor’s motto, “solving for space solves for Earth,” dedicated to addressing air-quality problems and Climate Change here at home.
To help NASA address these problems, the leading crowdsourcing platform HeroX has launched two new incentive challenges. First, there’s the “Waste to Base Materials Challenge: Sustainable Reprocessing in Space,” which seeks innovative solutions for what to do about all the waste that’s generated during long-duration spaceflights. (human and otherwise). Second, there’s the “NASA Air-athon Challenge,” which is looking to foster high-resolution air quality information to improve public health and safety.

The pandemic caused by the novel coronavirus is creating all kinds of chaos for human society. But for the dear old Earth, and the humans and creatures that breathe its air, it’s a bit of a reprieve. Mirroring what happened in China during lock-down, Europe is now seeing the same drop in air pollution.

By definition, pollution refers to any matter that is “out of place”. In other words, it is what happens when toxins, contaminants, and other harmful products are introduced into an environment, disrupting its normal patterns and functions. When it comes to our atmosphere, pollution refers to the introduction of chemicals, particulates, and biological matter that can be harmful to humans, plants and animals, and cause damage to the natural environment.
Whereas some causes of pollution are entirely natural – being the result of sudden changes in temperature, seasonal changes, or regular cycles – others are the result of human impact (i.e. anthropogenic, or man-made). More and more, the effects of air pollution on our planet, especially those that result from human activity, are of great concern to developers, planners and environmental organizations, given the long-term effect they can have.
