A new study founded by NASA and published on November 11 in Proceedings of the National Academy of Sciences, shows a 13-year decline in vegetation in the eastern and southeastern Amazon. While the decline was small, the area affected encompassed 5.4 million square kilometres, equivalent to over half the area of continental United States.
NASA satellites were fundamental in the study and were used to measure the "greenness" of the vegetation in the Amazon. Moreover, they were used in a new and innovative way.
On 29 April 2014, a new animation of the storm system which spawned 31 tornados affecting seven states across the Central and Southern United States from 27 to 28 April 2014 has been released by NASA using data collected from a NOAA’s GOES East Satellite and NASA’s Aqua Satellite.

On March 11, 2011, the Great Tohoku Earthquake occurred approximately 70 kilometers off the coast of Japan. This magnitude 9.0 earthquake was closely followed by a massive tsunami that reached 7 meters in height. Using NASA
