Mission Cheops will monitor single, but very bright stars
Astronomers in Europe decided to watch more closely the lonely, but bright stars. To find out at least the reason for their appearance in such unusual places and why it became so bright that was the reason. In order to study different phenomena in this direction, scientists decided to equip in November next year a special mission Characterising Exoplanet Satellite (Cheops). The Soyuz space rocket will deliver the spacecraft to orbit, the launch is already scheduled from the Equatorial cosmodrome on November 14, 2019. This time, an artificial satellite Cosmo-SkyMed will also be launched into orbit in a pair. This is a satellite relay of Italian origin. One satellite after the launch will go into its low orbit, and the Cheops will adjust so that it went a little further and took place at an altitude of 700 km above The earth`s surface.
At this altitude, the atmosphere is almost there, so without any problems it will be possible to study the distant and very bright stars. These bright stars are interesting only because they have in their orbits were previously discovered super large exoplanets. Observations are primarily needed in order to identify the transit method of the planet in the orbit of such bright stars. If the planets still have an atmosphere, it will be possible to find out its composition by the spectrum of light streams passing through it from the star. On Board such a complex equipment that it will allow to observe several transit passes, which are primarily needed in order to determine the real size of the exoplanets.
Planets and the distant bright stars, and has previously been found, moreover a lot of interesting planets already known. Now, knowing the visible size of the planet, it will be possible to calculate the density of the substance from which it consists. Such data will allow you to know more about how such planets as the Earth or Neptune are formed in the orbits of super bright and hot stars, which are considered to live not long, but very bright life.
While Cheops satellite is still in the laboratory, but the tests are in full swing, now it is on the test stand of Airbus Defence and Space in Spain, then he will be given a start in life by checking the survivability of all systems in the most extreme conditions.
