NASA Satellite Captures EPIC View of Earth’s Clouds and More (Video)

NASA’s Earth Polychromatic Imaging Camera — or EPIC for brief — is vital adult to a acronym, by producing visually overwhelming and scientifically fascinating images of Earth.

EPIC lives onboard NASA’s Deep Space Climate Observatory (DSCOVR), that orbits a object about 1 million miles from Earth — a ideal vantage indicate to take a picture of Earth’s whole sunlit face any 2 hours. A new video from NASA explains how this plcae allows EPIC to lane facilities like clouds, particulates in a atmosphere or volcanic charcoal clouds. It will also yield information about a appetite bill of a world — an critical square of information for meridian models.

Today (Dec. 14), during a annual assembly of a American Geophysical Union, scientists expelled new images taken by EPIC, and described some of a scholarship it will facilitate.[See some-more photos from NASA’s Deep Space Climate Observatory]

“We’ve grown accustomed to saying images of a world from space,” says a new video constructed during a NASA Goddard Spaceflight Center. “But full Earth views […] have indeed usually been seen by astronauts on their approach to a moon, and a handful of retreating probes, like Galileo, as they peered behind toward home for a final time.” 


As many people are good aware, satellites orbiting a Earth yield “high fortitude images of a world any day,” according to a video. But as a video explains, these satellites are too tighten to a aspect of a Earth to constraint a whole face during once. Instead, they have to take many cinema as they loop around and around Earth. The cinema are afterwards gathered into a singular image. But that means these images don’t uncover changing features, like storms, during a same indicate in time. EPIC, on a other hand, provides a finish perspective of a Earth face in any image.

“It’s a usually perspective we have like this where all is during a accurate same present in time, even yet a internal times are different,” Jay Herman, EPIC instrument lead questioner during Goddard, pronounced in a matter from NASA. With this capability, it’s probable for scientists to watch storms or clouds of dirt as they pierce opposite a planet. “We can see a course in genuine time,” Herman said.

EPIC will furnish beautiful tone images of a Earth, though it also take cinema in ultraviolet and near-infrared light, that are improved for tracking some features, a scientists during a AGU assembly said. The scholarship of EPIC is rather expansive, and will embody assisting to measuring Earth’s appetite change (which is formed partly on how most object is engrossed and reflected by a planet). That information is used in meridian models. Scientists are also “analyzing EPIC information to improved know vegetation, aerosols, ozone and other facilities of Earth and a atmosphere,” according to a matter from NASA.

DSCOVR launched on Feb. 11 of this year, aboard a SpaceX Falcon 9 rocket. The plcae where it orbits a object is famous as a initial Lagrange point, or L1, a place where a gravitational lift of a object and a Earth “balance out,” permitting booster to stay comparatively stable, a scientists said. It is also carrying instruments that will investigate a sun, and maybe yield information that could assistance scientists envision solar flares and other dangerous space continue events.
