Monitoring life on Earth from space
Today’s Video of the Day comes from NASA Goddard and features a look at how scientists monitor life on Earth from space.
In 1997, NASA launched a specialized satellite that spent 20 years measuring life on Earth to create a comprehensive view of global biology.
The data set, animated in this video, shows a repetitious ebb and flow of photosynthesis which is essentially planet Earth breathing.
