Spacecraft Solar Probe Plus will go on a record approach to the Sun



    And no wonder, because this spacecraft must enter the atmosphere of the sun. Not in the hottest layers, of course, but the temperature where the probe is going is decent.

    In this spacecraft will be collected all the latest technological developments related to the Sun and its research (as well as protection from the Sun, of course).

    The project itself is designed to collect the most detailed information about the Sun and its impact on the Earth, including the biosphere and noosphere, if I may say so. True, the launch of the probe is still far - it is planned that the Solar Probe Plus will fly to the Sun, only in 2018, in the summer.

    After launching, the probe will not immediately approach the Sun at a minimum distance, but will make revolutions around the star. In total, it is planned to make 24 turns, with a gradual approximation of 6 million kilometers. The previous record of approaching the Sun belongs to the Helios-B apparatus, which approached 42 million kilometers.

    The design of the Solar Probe Plus will use a protective shield, which previously showed itself well during the flight of the Messenger station to Mercury. This screen allows you to withstand very high temperatures, up to 1400 degrees Celsius. Active solar panels and all other methods of protection against high temperature and interference will be used.

    Solar Probe Plus will have five major scientific systems. These are Solar Wind Electrons Alphas and Protons (SWEAP), Wide-field Imager for Solar Probe Plus (WISPR), Fields Experiment, Integrated Science Investigation of the Sun (ISIS), and Heliospheric Origins with Solar Probe Plus.

    Using these tools, scientists hope to obtain detailed stereometric images of the solar corona, to study the composition of the solar wind, to obtain information about electromagnetic and radiation fields, to study the atmosphere of the sun and to perform a number of related studies.
