One Year on Earth – Seen From 1 Million Miles

One Year on Earth – Seen From 1 Million Miles

"

" I'm Jay Herman. I'm the EPIC Lead Scientist for the DSCOVR mission.  On July 6, 2015, we released this spectacular image of Earth taken by NASA's EPIC camera.  Now, we assembled more than 3,000 images captured by EPIC into a time-lapse sequence that shows a year in the life of our planet.  EPIC is an Earth science instrument aboard the DSCOVR satellite, which launched in February 2015.  The

spacecraft always remains between the sun and the Earth  approximately 1 million miles away, at a special gravitational balance point known as Lagrange 1.  From this view, EPIC sees the sunrise in the west and the sunset in the east  at least 13 times a day.  The haze seen around the edges is due to scattering of light by molecules in the atmosphere.   Scattering is also what makes the sky

appear blue during the day and red at sunset.   The colors shown are our best estimate of what a human sitting at the location of EPIC would see.  EPIC takes at least one set of images about every two hours.   The camera records each set in 10 different wavelengths.   At least three separate wavelengths--red, green, and blue--are combined to produce this color view.  In March, the moon passed

between the Earth and the sun causing a total solar eclipse.  During the eclipse, the moon cast its shadow over a portion of the planet.  If we slow the video down, we can see the moon's shadow make an appearance right about now.  Although the view from EPIC is only once every two hours, we're able to track features like the motion of clouds.  Around two-thirds of the Earth is

covered by clouds.   Clouds reflect light from the sun, helping to keep the planet cool.  They also trap heat rising from the surface, keeping the planet warm.  Changes in cloud cover affect the heat balance and how warm the Earth becomes, which is one of the reasons why we study them.  The hourly images of the entire sunlit side of the Earth provided by EPIC  will be used to study

the daily variations of features over the entire globe  helping us to better understand and protect our home planet.
