NASA’s new website allows world to see sunlit side of earth every day

On a daily basis, NASA will upload at least a dozen new coloured images of earth on its new website. It will allow people to see the sunlit side of our Mother Planet. These images will be captured by a camera on the Deep Space Climate Observatory (DSCOVR) present one million miles away from earth.

The project is part of partnership between NASA, the National Oceanic and Atmospheric Administration (NOAA) and the US Air Force. The images as stated above will be posted daily are taken 12 to 36 hour before by NASA's Earth Polychromatic Imaging Camera (EPIC).

Every new sequence of the images will provide a view of earth's rotation. The website also has an archive of EPIC images, which can be searched through date and continent. Main aim of the DSCOVR is ensure the solar wind monitoring capabilities, which are quite important NOAA to make space weather alerts and forecasts.

In total, the spacecraft has two earth-observing instruments. EPIC, which is a four megapixel CCD camera and telescope, allow scientist to properly go through regular changes on earth in terms of variation, ozone, aerosols and reflectivity.

"The effective resolution of the DSCOVR EPIC camera is somewhere between 6.2 and 9.4 miles (10 and 15 kilometers", said Adam Szabo, DSCOVR project scientist at NASA's Goddard Space Flight Center, Greenbelt, Maryland. Earth being very bright makes EPIC to take very short exposure images.
