Tag Archives: Earth Polychromatic Imaging Camera

The Earth Polychromatic Imaging Camera (EPIC) is attached on NASA’s Deep Space Climate Observatory (DSCOVR). It takes images of the sunlit side of Earth for various Earth sciences purposes, in 10 different channels from ultraviolet to near infrared. Ozone and aerosol levels will be monitored, as well as cloud dynamics, properties of the land and vegetations.

EPIC has an aperture diameter of 30.5 cm (12.0 in), f 9.38, a FOV of 0.61° and an angular sampling resolution of 1.07 arcsec. Earth apparent diameter will vary from 0.45° to 0.53° full width. Exposure time for each of the 10 narrowband channels (317, 325, 340, 388, 443, 552, 680, 688, 764 and 779 nm) is about 40 ms, and the camera will produce 2048×2048 pixel images, but to increase number of downloadable images to 10 per hour the resolution will be averaged to 1024×1024 on board. The final resolution will be 25 km/pixel (16 mi/pixel).

Total Solar Eclipse 2017 Images From Space

On Monday, August 21, an estimated 2 million to 7.4 million Americans traveled to see the first total solar eclipse in 99 years to go coast to coast in the United States, which went from Lincoln Beach, Oregon, to Charleston, South Carolina. But, some of them were unlucky, as the weather was overcast in some places. But, luckily for them (and for us), NASA captured some amazing and beautiful images of the eclipse and published them on their website.

A Year of Earth From a Million Miles Away

A year after returning its first image, NASA’s EPIC camera, a four megapixel CCD camera and telescope attached the Deep Space Climate Observatory (DSCOVR) shows us an entire year of Earth from almost one million miles away. The result is the amazing video below.

With the voice of Jay Herman, EPIC lead scientist.

Moon Transiting the Earth – EPIC View

An “EPIC” animation of the Moon transiting the Earth created with actual satellite images of the far side of the moon, illuminated by the Sun. The images are taken by NASA’s Earth Polychromatic Imaging Camera (EPIC), a four megapixel CCD camera and telescope attached to the Deep Space Climate Observatory (DSCOVR). While the moon was crossing between the DSCOVR and the Earth, EPIC took these beautiful photos almost one million miles from Earth.

The distance between the Moon and Earth varies from around 356,400 km to 406,700 km at the extreme perigees (closest) and apogees (farthest).

“EPIC” Earth Image by NASA

At the Sun-Earth L1 Lagrangian point, 1,500,000 km (930,000 mi) from Earth; NASA’s Deep Space Climate Observatory took an amazing photo of the entire sunlit side of Earth on July 06, 20145. The photo was taken by NASA’s Earth Polychromatic Imaging Camera (EPIC), a four megapixel CCD camera and telescope.

The final image showing the North and Central America was generated by combining three separate images to create a photographic-quality image. The camera takes a series of 10 images using different narrowband filters — from ultraviolet to near infrared — to produce a variety of science products. The red, green and blue channel images are used in these color images.
