* Developed new technologies to clean up air pollution. NASA has developed a number of new technologies to clean up air pollution, including:

* The catalytic converter, which converts harmful pollutants into less harmful substances

* The electrostatic precipitator, which removes particles from the air by charging them and then attracting them to a negatively charged plate

* The scrubber, which removes pollutants from the air by passing it through a liquid or gas

* Monitored air quality. NASA uses satellites to monitor air quality around the world. This data is used to track pollution trends, identify sources of pollution, and develop air quality regulations.

* Educated the public about air pollution. NASA provides educational resources about air pollution to the public. This information helps people understand the causes and effects of air pollution, and how they can reduce their exposure to it.

Water

* Developed new technologies to clean up water pollution. NASA has developed a number of new technologies to clean up water pollution, including:

* The reverse osmosis membrane, which removes impurities from water by passing it through a semi-permeable membrane

* The activated carbon filter, which removes impurities from water by adsorbing them onto activated carbon

* The ultraviolet light disinfection system, which kills bacteria and other microorganisms in water

* Monitored water quality. NASA uses satellites to monitor water quality around the world. This data is used to track pollution trends, identify sources of pollution, and develop water quality regulations.
