Planet Earth

  • Released Thursday, October 2, 2014

Earth is constantly changing, and NASA scientists and engineers are working daily to explore and understand the planet on scales from local to global. Though Earth science has been a key part of NASA’s mission since the agency was founded in 1958, this year has been one of the peaks. Three Earth-observing missions—two satellites and one instrument—have already been launched and two more missions are set to take off later this year. All of these new efforts complement an existing fleet of Earth-observing satellites and research aircraft that monitor our world. Watch the video to see a time-lapse that shows land and cloud changes in the eastern hemisphere as seen by the NASA-NOAA Suomi NPP satellite.
