NASA’s Terra spacecraft had been orbiting around the Earth for almost 16 years, which is equipped with a Japanese instrument called the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER ) and that has been capturing pictures of the Earth since it launched into space in 1999.
It is said that it had pictured around 99% of the surface of the Earth, where its data and images weren’t free to public until now. NASA and Japan announced together on April 1 that 2.95 million images of the planet are now free to access and analyze, even you can download them.
Every picture taken by ASTER looks like they were marked up with colors, but that’s because the images were captured using an infrared camera, so the changes in surface temperatures, materials and elevation have had created different color patterns.
