On the official channel of the American space Agency NASA in Youtube there is a video which takes less than three minutes to see a year on Earth, how it looked, if you look at our planet from the Sun. The video is composed of pictures taken by the instrument of the satellite DSCOVR EPIC, and is accompanied by English speaking review specialist.
The satellite DSCOVR (Deep Space Climate Observatory) launched from Cape Canaveral in February 2015, is always situated between the Earth and the Sun in the so-called point of the Lagrange point L1. At this point the gravitational influence of the planets and luminaries are balanced, and that keeps the satellite where it needs to be. The location of the device allows him to constantly see the Earth with the “day” side, and the sunsets and sunrises on its “territories” fall into the lens tool, the EPIC not less than 13 times a day. “The main mission of the satellite is to monitor space weather — solar wind, coronal mass ejections, and so on
Every two hours the machine makes a series of ten pictures, each of which corresponds to a certain wavelength of radiation coming from the Earth. In order to obtain the image of which is formed by the roller, the scientists combined several of these shots, primarily those in human perception correspond to blue, green and red color. Thus, the video colors reminiscent of the spectacle that presented itself to a man, if he were in the place of DSCOVR.
The entire video consists of approximately three thousand photographs taken in the period August 2015 to July 2016. Although such a high speed of change of shots is somewhat hindered to see the history of the Earth “in detail”, some leisurely processes — for example, the movement of clouds — in the video you can trace, experts say. And at the end of the second minute of the video, the scrolling speed of the frames slowed briefly, to the audience it easier to see the shadow that the Earth cast by the Moon during a total solar Eclipse 9 March 2016.Related posts:
