DSCOVR was originally proposed as an Earth observation spacecraft positioned at the [[Earth's orbit|Sun-Earth]] {{L1}} [[Lagrange point]], providing live video of the sunlit side of the planet through the Internet as well as scientific instruments to study climate change. Political changes in the [[United States]] resulted in the mission's cancellation, and in 2001 the spacecraft was placed into storage.

Proponents of the mission continued to push for its reinstatement, and a change in presidential administration in 2009 resulted in DSCOVR being taken out of storage and refurbished, and its mission was refocused to solar observation and early warning of [[coronal mass ejection]]s while still providing Earth observation and climate monitoring. It launched aboard a [[SpaceX]] [[Falcon 9]] launch vehicle on 11 February 2015, and reached {{L1}} on 8 June 2015, joining the [[List of objects at Lagrange points|list of objects orbiting at Lagrange points]].

NOAA operates DSCOVR from its [https://www.ospo.noaa.gov/ Satellite and Product Operations Facility] in [[Suitland, Maryland]]. The acquired space data that allows for accurate weather forecasts are carried out in the [[Space Weather Prediction Center]] in [[Boulder, Colorado]]. Archival records are held by the [[National Centers for Environmental Information]], and processing of Earth sensor data is carried out by [[NASA]].<ref name="dscovr-infosheet"/>
