Comet Churyumov-Gerasimenko with the module “Fily” reached the nearest point to the Sun
Apparatus “Rosetta” was launched into space in March 2004 with a spaceport in Kourou to study the comet 67P/ Churyumov-Gerasimenko. To the destination apparatus has arrived in 2014 and is currently in orbit around the comet. November 12, 2014 on the surface of the investigated object was launched module “Fily”. He entered the history of space exploration, as the first probe successfully landing on a comet for the first time and managed to drill the surface for the taking of soil samples. Thanks to this unique scientific mission scientists expect to obtain detailed data about the physical and chemical structure of the comet, which will greatly expand human knowledge about the origin of the Universe.
According to him, the closer to the star in recent months, the comet’s activity has steadily increased. This is evidenced by the comparison of Photographs taken by Rosetta, the robot lander with a difference a year last summer and now. Continue reading
Unlike planets, comets move on highly elongated orbits, and therefore are visible only at short periods close to the Sun.
The main part of any comet is its nucleus .
According to the hypothesis of the famous American researcher of comets Fred Lawrence Whipple, cometary nucleus is an ice consisting of a mixture of frozen water and frozen gases interspersed with refractory rocky and metallic particles . Figuratively speaking, it looks like a “dirty iceberg”.
Let us imagine that we see the newly opened the comet, which is somewhere in the vicinity of Jupiter’s orbit. Seeing through the telescope hazy pale speck, like a spherical nebula (such unattractive are presented to the observer of a distant comet), we may be disappointed at first. With the approach of the comet to the Sun the solar flux increases. Comet “ice” begin to evaporate rapidly. Around the nucleus formed a vast glowing gas shell – coma. Together with the core of it is the head of the comet. Continue reading
Modern physics. A flight to Mars.
Russia is technically ready to organize a manned mission to Mars in early 2020-ies, the Director of the space research Institute of Russian Academy of Sciences the academician the lion Green.
“Priority for Russia, and prestigious really the first to disembark an astronaut on Mars. This problem is economically and technically solved”, — said L. Green. According to him, if to begin preparations for flight in the near future, Russian cosmonauts can land on the surface of Mars in 2023-2025 years.
For the organization of the expedition, says L. Green, hurt Russia more than any other country, including the United States.
“We now have a certain handicap in this race, as we have the biggest experience in manned space exploration. Even in the bad 90’s, he worked as the station “Mir”, then there was the ISS. Thus a chain of manned flights have not been interrupted,” — said the scientist. Continue reading
