NASA has released the first image of the probe DSCOVR (Deep Space Climate Observatory). It is no accident seen on the entire illuminated hemisphere of the Earth from the Americas. The image, taken from a distance of more than half a million kilometers shows the possibility of a new EPIC camera that will be used for climate research. Since September, these photos will be presented on a special website every day, from 12 to 36 hours after taking them.
DSCOVR probe mission is a joint project of NASA, NOAA (National Oceanic and Atmospheric Administration) and the US Air Force, which aims to provide constant monitoring of the impact of space weather including solar activity on the climate conditions on Earth. The satellite was launched in February, rockets aboard the Space X Falcon 9, she recently arrived on the scheduled orbit in the region point libracyjnego, otherwise known as Lagrangian point L1. At this point, on the Earth – Sun probe can remain at rest with respect to both of these celestial bodies and have a constant view of the lighted at the moment hemisphere of the Earth.
From this unique place, with the help of the EPIC camera can conduct observations level ozone and aerosols in the atmosphere of the Earth, the level of cloud cover of vegetation, and finally the extent to which reflects incident on the earth than the ultraviolet radiation. NASA also plans to help her investigate other phenomena, such as the distribution of volcanic ash.
EPIC camera photos (Earth Polychromatic Imaging Camera) may contain information of 10 images collected with the help of narrowband filters from the ultraviolet to the near infrared. In the case of such images, as seen above, uses the image of the filters red, green and blue, as in normal photographs.
