On Thursday from air base Vandenberg in California was started the rocket Pegasus XL with [ad name=”Google Adsense-3 11″] specialized solar observatory of IRIS device onboard. The satellite intended for research of processes in the atmosphere of the Sun, is successfully put to settlement orbit. The IRIS device is calculated on two years of active work. In the next month it will pass flight tests then scientists will start to work. The ultra-violet telescope established onboard with a 20-centimetric mirror will allow in combination with the new spectrograph and the camera to receive earlier inaccessible information on the Sun atmosphere. The satellite is made counting upon detailed research of the photosphere, the chromospheres and so-called transitional layer. The transitional layer is the most top layer in the solar atmosphere and separates a solar crown from the chromospheres. Processes in this layer influence both solar flashes, and formation of streams of the loaded particles from the Sun during rather quiet periods. Therefore the studying the Sun is important not only from the theoretical point of view. In same rather thin (only from 6 to 9 thousand kilometers) a cover there is a warming up of plasma leaving in a crown. With help of IRIS device researchers expect to receive the most detailed images of a transitional layer. Resolution of the new tool will allow to distinguish on the Sun the details with the size up to 240 kilometers in the diameter. Among the devices NASA, which are studying the Sun there is a solar observatory of SOHO constructed together with ESA, two satellites for three-dimensional supervision of STEREO and space observatory of SDO. For the majority of NASA satellites originally taken away service life lasted therefore SOHO started still in 1995, still continues to transfer new data to Earth.
