A new Multi-spectral Drought Index measures the impacts of too little water or too much rainfall on vegetation. The index will also be used to verify other existing drought-monitoring products. The NDVI is an index created by Tucker 20 years ago to measure the absorption and reflectance of sunlight by plants. A new way of accessing and downloading images, animations and visualizations of the Earth is now available. Images are categorized by location, satellite, and topic, and are also searchable using a full-text search engine.
New images are uploaded daily and highlighted on the front page.

The launch of Space Shuttle Atlantis STS-106 has been set for Sept. 8, on a mission that will open the doors to the International Space Station's new living quarters. This mission begins a series of Station assembly flights aboard the Shuttle during the next year. During the planned 11-day flight, the crew of seven will spend a week docked to the International Space Station, unloading more than one and a half tons of equipment and supplies from both the Shuttle and from a docked Russian Progress cargo craft.
