Once the instrument begins regular data acquisition, new images will be available every day, 12 to 36 hours after they are acquired by EPIC. The EPIC team is developing data processing techniques that will emphasize land features and remove this atmospheric effect. This first public image shows the effects of sunlight scattered by air molecules, giving the disk a characteristic bluish tint. When EPIC collects data, it takes a series of 10 images at different bands-from ultraviolet to near infrared.) (Bands are narrow regions of the electromagnetic spectrum to which a remote sensing instrument responds. The image above was made by combining information from EPIC’s red, green, and blue bands. At L1-four times farther than the orbit of the Moon-the gravitational pull of the Sun and Earth cancel out, providing a stable orbit and a continuous view of Earth. After journey of about 1.6 million kilometers (1 million miles) to the L1 Lagrange Point, the satellite and its Earth Polychromatic Imaging Camera (EPIC) has returned its first view of the entire sunlit side of Earth. On February 11, 2015, DSCOVR was finally lofted into space by a SpaceX Falcon 9 rocket. Air Force decided to refurbish and update the spacecraft for launch. In 2008, the National Oceanic and Atmospheric Administration (NOAA), NASA, and the U.S. The mission was put on hold in 2001, and the partly-built satellite ended up in storage for several years with an uncertain future. Once known as Triana, the satellite was conceived in 1998 to provide continuous views of Earth, to monitor the solar wind, and to measure fluctuations in Earth’s albedo. The journey has been a long one for the Deep Space Climate Observatory (DSCOVR). In fact, other satellites-including Galileo, the Lunar Reconnaissance Orbiter, and geostationary weather satellites including GOES-have captured full-disc views of Earth since then. Editor’s Note: An earlier version of this story stated that it has not been possible to capture images of the entire sunlit side of Earth since Apollo 17 astronauts captured the iconic Blue Marble photograph in 1972.
