Deep Space Climate Observatory (DSCOVR; formerly known as Triana, unofficially known as GoreSat[3]) is a National Oceanic and Atmospheric Administration (NOAA) space weather, space climate, and Earth observation satellite. It was launched by SpaceX on a Falcon 9 v1.1 launch vehicle on 11 February 2015, from Cape Canaveral.[4] This is NOAA's first operational deep space satellite and became its primary system of warning Earth in the event of solar magnetic storms.[5]
DSCOVR was originally proposed as an Earth observation spacecraft positioned at the 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 ejections 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 orbiting at Lagrange points.
NOAA operates DSCOVR from its 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.[1]
