Deep Space Climate Observatory

Astronomy
  • A joint NOAA/NASA spacecraft to observe the solar wind, launched in 2015 February. From its position in orbit around the L1 Lagrangian point 1.5 million km sunwards of the Earth it measures the strength and direction of the interplanetary magnetic field and the speed and density of the solar wind approaching the Earth. These observations are used by NOAA’s Space Weather Prediction Center in Boulder, Colorado, to forecast space weather that can affect the Earth and orbiting satellites. DSCOVR also measures the visible and infrared light reflected by the sunlit side of Earth (the Earth’s energy balance) to improve climate models.

The satellite was launched on 11 February 2015, from Cape Canaveral, Florida.
