Review of the mission ExoMars-2016
March 14, 2020 the Russian and European space agencies signed an agreement that turned a large-scale European program for the exploration of Mars in a joint project. The program is divided into two stages, the implementation of which is planned for 2016 and 2018. The approach of the first date gives reason to discuss in detail the mission “ExoMars-2016” (ExoMars 2016).
For the first phase of the mission “Eczemas” are mainly responsible of the European space Agency. Russia will provide launch vehicle “proton-M” to launch spacecraft and some scientific instrumentation. Like many automatic stations, “ExoMars-2016” will consist of two blocks, orbital and ground. Is called the orbital module TGO Trace Gas Orbiter, a Satellite to monitor gases. The lander, known as EDM (Entry, Descent and Landing Demonstrator Module the demonstrator inputs, approach and landing), was named in honor of the Italian astronomer Giovanni Schiaparelli.

The biggest of all open still planets astronomers found in the constellation of Hercules.
Space body, named TrES-4, is drawn around the star GSC02620-00648, remote from the Earth at a distance of 1435 light-years. A new extrasolar planet about 70% larger size than Jupiter, but has a much smaller mass, which indicates its extremely low density. In addition, the object is deleted only 7 million kilometers from its star, making its surface extremely hot, over 1300 degrees Celsius.
Around its star turns the planet every 3.55 days, you one earth week to two years, listed on TrES-4. Because of the relatively weak gravity TrES-4, probably permanently loses a part of the upper layer of its atmosphere, which stretches behind the planet in the form of a curved tail resembling a comet.
“This is the largest of all known exoplanets, says lead researcher George Mandushev from the Lowell Observatory. It is so large that using existing scientific models to superhot giant planets its size is quite difficult to describe. Continue reading
Halley’s comet is the only short-period comet that is clearly visible to the naked eye
Halley’s comet is the most popular of comets. It rotates around the Sun with a period of 74 to 79 years in highly elliptical orbit. During the appearance of the comet in 1835 with the help of spectral analysis it was found that the composition of cometary atmospheres observed molecular bands of CYANOGEN, carbon monoxide and other compounds. So quickly spread rumors about poisoning the earth’s atmosphere hazardous to human health toxic cometary gases.
As predicted by astronomers, may 19, 1910 the Earth “collided” with the tail of Halley’s comet. However, even the most sensitive instruments have not detected any unusual phenomena in the Earth’s atmosphere, which could uniquely associate with this event. So the wave of fear that swept through many countries in may 1910, had under itself no soil.
After passing through the tail of Halley’s comet, the Earth appeared as a kind of probe. It should be noted that the Earth has been repeatedly passed through the tails of comets, and the effect was always the same – no influence on processes in the earth’s atmosphere substance of different tails of comets were not provided.
