From the vantage point of L1, DSCOVR’s EPIC camera has captured its first EPIC’s first view of a full Earth from the Sun-Earth L1 point. We are excited to begin registration for the EPIC (Earth science Project International Collaborative) Workshop. The meeting will focus on. Images of the Earth from DSCOVR:EPIC allow us to explore the Earth as though it were an exoplanet. [Adapted from Jiang et al. ].

Over on the left is the image info box that tells you when the image was acquired. If you watch the videos you’ll realize that this isn’t an “Earthrise” — from the point of view of the spacecraft, Earth is setting.

This data is to be used to study changes in Earth’s radiation budget caused by natural and human activities. It’s from that unique vantage point that the EPIC instrument is acquiring science aertth images of the entire sunlit face of Earth. They only took this one image as a test. Because the filters are so narrowband, a straight combination of red, og, and blue filter images wouldn’t make a photo with as much verisimilitude as the one released today.
The Moon transiting Earth, July 16, In November the satellite was removed from storage and began recertification for a possible launch on board a Delta II or a Falcon 9. The Earth Polychromatic Imaging Camera EPIC takes images of the sunlit side of Earth for various Earth science monitoring purposes in 10 different channels from ultraviolet to near-infrared. One might want to have a scientific discussion on that very subject, “Is the Earth more Spherical than Oblate?
It is well worth enlarging to its full by pixels.
NASA satellite camera provides ‘EPIC’ view of Earth
As a result of its closer viewpoint, points near the center of the globe are much closer to the viewer than points at the globe’s edge, so features near the center bulge — it’s the same effect that tends to make your nose look big when you take a selfie.
Archived from the original on June 8, But the EPIC instrument is equally sensitive to all of the filter settings. February 11, It sends back thousands of amazing photos aerfh year, and now you can peruse them more easily with the new website.
Ms Lakdawalla, Thank you for your clarification. Retrieved July 21, They’re still not perfect though; to do better than that, you need a spectrometer that can image in many, many wavelengths and then convolve the spectral data with human visual response.

I’ve aligned the two images so that you can compare them:. Aerh will usually be able to provide a to minute warning before a surge of particles and magnetic field, from a coronal mass ejection CME reaches Earth and creates a geomagnetic storm.
