Description 
A descriptive note detailing the content and context of the digital collection.
The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) instrument is one of NASA’s five Earth-observing instruments. Launched on December 18, 1999, on the Terra satellite, ASTER “images Earth to map and monitor the changing surface of our planet” by capturing high-resolution (15 to 90 square meters per pixel) images of the Earth. Since then, more than 2.95 million images were captured. The content “ranges from massive scars across the Oklahoma landscape from an EF-5 tornado and the devastating aftermath of flooding in Pakistan, to volcanic eruptions in Iceland and wildfires in California”. Users can view a fraction of the images from this website, while the rest can be accessed from a series of different tools provided.
