Operation
On 6 July 2015, DSCOVR returned its first publicly released view of the entire sunlit side of Earth from 1,475,207 km (916,651 mi) away, taken by the EPIC instrument. EPIC provides a daily series of Earth images, enabling the first-time study of daily variations over the entire globe. The images, available 12 to 36 hours after they are made, have been posted to a dedicated web page since September 2015.DSCOVR was placed in operation at the L1 Lagrange point to monitor the Sun, because the constant stream of particles from the Sun (the solar wind) reaches L1 about 60 minutes before reaching Earth. DSCOVR will usually be able to provide a 15 to 60 minutes warning before a surge of particles and magnetic field from a coronal mass ejection (CME) reaches Earth and creates a geomagnetic storm. DSCOVR data will also be used to improve predictions of the impact locations of a geomagnetic storm to be able to take preventative action. Electronic technologies such as satellites in geosynchronous orbit are at risk of unplanned disruptions without warnings from DSCOVR and other monitoring satellites at L1.On 16–17 July 2015, DSCOVR took a series of images showing the Moon during a transit of Earth. The images were taken between 19:50 and 00:45 UTC. The animation was composed of monochrome images taken in different color filters at 30-second intervals for each frame, resulting in a slight color fringing for the Moon in each finished frame. Due to its position at Sun–Earth L1, DSCOVR will always see the Moon illuminated and will always see its far side when it passes in front of Earth.On 19 October 2015, NASA opened a new website to host near-live "Blue Marble" images taken by EPIC of Earth. Twelve images are released each day, every two hours, showcasing Earth as it rotates on its axis. The resolution of the images ranges from 10 to 15 km per pixel (6 to 9 mi/pixel), and the short exposure times renders points of starlight invisible.On 27 June 2019, DSCOVR was put into safe mode due to an anomaly with the laser gyroscope of the Miniature Inertial Measurement Unit (MIMU), part of the spacecraft's attitude control system. Operators programmed a software patch that allows DSCOVR to operate without a laser gyroscope, using only the star tracker for angular rate information. DSCOVR came out of the safe hold on 2 March 2020, and resumed normal operations.
