Earth Time-lapse

From a dusty atmosphere stretching across the Atlantic Ocean to daily views of clouds at sunrise, a NASA camera keeping a steady eye on the sunlit side of Earth is yielding new insights about our changing planet. The EPIC camera is stationed in space one million miles away, affixed to NOAA’s DSCOVR satellite. DSCOVR was launched on February 11, 2015, and, after a four-month journey, reached its orbit around the first Lagrange point, where the matching pull of gravity from the sun and Earth allows the satellite to stay relatively stable between the two bodies. From this distant outpost, EPIC captures a color image of the sunlit side of Earth at least once every two hours, allowing researchers to track features as the planet rotates in the instrument’s field of view. EPIC also collects measurements in ultraviolet and near-infrared wavelengths that help scientists study various aspects of Earth and its atmosphere. Watch the video to see a time-lapse of Earth created from images taken by EPIC.
