NASA’s Deep Space Climate Observatory satellite has sent back a picture of the Earth. The picture that the satellite sent back was taken at a distance of one million miles away from Earth!
The camera, NASA’s Earth Polychromatic Imaging Camera (EPIC), is a four megapixel CCD camera and telescope. By combining three separate images, the camera was able to create a photographic-quality image.
The image was taken July 6, 2015, showing North and Central America. The central turquoise areas are shallow seas around the Caribbean islands. This Earth image shows the effects of sunlight scattered by air molecules, giving the image a characteristic bluish tint. The EPIC team is working to remove this atmospheric effect from subsequent images. Once the instrument begins regular data acquisition, EPIC will provide a daily series of Earth images allowing for the first time study of daily variations over the entire globe. These images, available 12 to 36 hours after they are acquired, will be posted to a dedicated web page by September 2015.
The primary objective of DSCOVR, a partnership between NASA, the National Oceanic and Atmospheric Administration (NOAA) and the U.S. Air Force, is to maintain the nation’s real-time solar wind monitoring capabilities, which are critical to the accuracy and lead time of space weather alerts and forecasts from NOAA.
