View Resource NASA Releases New Way to Measure Drought

NASA has unveiled its new Multi-Spectral Drought Indexer (MSDI), improving existing technology for measuring absorption and reflection of sunlight by plants in order to make maps of unprecedented detail. The data, which come from satellites, are translated by researchers into monthly maps of vegetation color changes, thus indicating how much soil moisture is available to plants. The existing...

View Resource Artificial Satellites

Over 2,000 man-made satellites are currently orbiting the Earth, providing a wide range of services like communications, remote sensing, and global positioning. As more are launched and new technologies are developed, they will play an increasingly important role in everyday life. The Tech Museum offers this site (1) dedicated to the basics of satellites and their functions. A Java program...
