Comet Churyumov-Gerasimenko

Comet Churyumov-Gerasimenko are two comets stuck together

The researchers of the mission “Rosetta” said the comet 67/P Churyumov-Gerasimenko acquired its form as a result of collision at a low speed of two different comets in the early development of the Solar system.

A team of researchers under the leadership of astrophysics Massironi Matteo (Matteo Massironi) from the University of Padova (Italy) look at the Photos of the comet 67P/Churyumov-Gerasimenko, taken in high resolution in the period between 6 August 2014 and 17 March 2015, it Became evident that the comet was formed as a result of collision of two different bodies, flying at low speed. The results of the ESA study says .

Recall, the first images of the comet from close range, the probe “Rosetta” in July 2014 showed that the object consists of two “blocks” of different sizes. and resembles the shape of a rubber duck. Scientists examined two hypotheses: the first is that the cosmic body had acquired such an unusual form as a result of a collision between two comets, and another stated that the “neck” of the comet formed in the process of natural erosion of rocks that make up the object. Now, however, the researchers got convincing evidence in favor of the first. Continue reading

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.

Comet

Comets are Solar system bodies having the form of vague objects, usually with pale clot kernel in the center and tail. They are among the most beautiful celestial bodies. hazy Bright shell surrounding a core of hazy, long tail, extending sometimes to half the sky, fast motion among the stars – all this makes comet different from other heavenly bodies. The comet can be observed when a small ice body, called the nucleus of the comet is approaching the Sun at a distance that is less than 4-5.e. warmed by the sun, and it begins to stand out gases and dust that are visible as a result of their illumination by the Sun.

Gases and dust released from the nucleus, creating around him a hazy shell – atmosphere of the comet, components along with the core of the head of the comet. The atmosphere of a comet continuously dissipates in interplanetary space: under the action of radiation pressure and interaction with the solar wind gases and dust are carried away in the direction from the Sun forming the comet’s tail.

Most of the comets in the middle of the head there is a bright star-like “core”, representing the illumination of the Central, most dense zone of true gases around the comet’s nucleus. Continue reading
