Space Technology and Earth

Space technology — satellites, sensors, and data systems launched into orbit — is one of the most powerful tools for understanding and protecting Earth's environment. Satellites provide a vantage point that's impossible from the ground: they can see entire oceans, continents, and ecosystems at once, and they can monitor changes over time. NASA's Earth science program operates dozens of satellites that measure sea level, ocean temperature, ocean color (which indicates algae and plankton), hurricanes, deforestation, ice cover, air quality, and many other parameters. For the Indian River Lagoon, satellite data is increasingly important: satellites can measure water clarity (turbidity), chlorophyll (which indicates algae blooms), sea surface temperature, and even track sediment plumes from storms. This 'big picture' data complements the ground-based monitoring stations in the lagoon, giving scientists a complete view of the lagoon's health from both the water and from space. The connection between space technology and lagoon protection is direct: the better we can see and measure the lagoon from space, the better we can manage and protect it.
