Future Nasa Concept Design

In one of the nation's largest restoration projects, NASA technology helps state and federal government reclaim 15,100 acres (61 km2) of salt evaporation ponds in South San Francisco Bay. Satellite sensors are used by scientists to study the effect of salt evaporation on local ecology.
NASA has started Energy Efficiency and Water Conservation Program as an agency-wide program directed to prevent pollution and reduce energy and water utilization. It helps to ensure that NASA meets its federal stewardship responsibilities for the environment.
• Earth Science Enterprise
Understanding of natural and human-induced changes on the global environment is the main objective of NASA's Earth Science Enterprise. NASA currently has more than a dozen Earth science spacecraft/instruments in orbit studying all aspects of the Earth system (oceans, land, atmosphere, biosphere, cyrosphere), with several more planned for launch in the next few years.
