[...] the DSCOVR satellite's main purpose is to observe space weather, such as magnetic fields emitted from the Sun that can muck up our planet's communication systems. The satellite was launched aboard a SpaceX Falcon 9 rocket in February and now sits at Lagrangian Point 1 [...]
This position also provides DSCOVR with a spectacular view of Earth. Fortunately, the satellite was equipped with a camera to capture our planet's facade called the Earth Polychromatic Imaging Camera, appropriately nicknamed EPIC. The camera is a powerful telescope, which takes a series of 10 images of Earth at a time in different light wavelengths — ranging from ultraviolet to the near infrared. The red, green, and blue channel images are combined together to make the spectacular color images of Earth, with resolutions between 6.2 and 9.4 miles per pixel.
