Space probe approaching Pluto after 9 years

The NASA probe New Horizons close to Pluto and will be able to enter the planet’s atmosphere in July of this year

The ship, which was launched back in 2006 has come nearer to the outer body at a distance that allows you to make high-quality pictures of its surface.

NASA may have to adjust its trajectory in case of detection of unknown cosmic bodies, reports Russia Today .

Apart from the modern equipment on Board the spacecraft is an urn with the remains of the discoverer of Pluto Clyde Tombaugh (1906-1997), CDs with a message to aliens, U.S. coins, flags and postage stamps. On Board the SPACECRAFT is the CD 434 738 names of people who participated in the campaign NASA “Send your name to Pluto” (Send Your Name to Pluto).

Task apparatus is the study of the atmosphere and the ground layers of Pluto, moreover, New Horizons will create a map of the surface of the farthest planet in our System. Continue reading

Great Hiking on the moon

China completed test heavy carrier rocket “Changzheng-5” (“long March 5”), which will be the basis for its lunar missions. Federal news Agency – at what level is the celestial space.

About the end of the test “Changzheng-5” according to the Chinese media. The development of these rockets was originally planned to be completed in 2008, but funding was only allocated in 2007. In the end, the first tests began in September of last year, and the first test flight is scheduled for September. In 2017 it is planned with the help of this rocket launch to the Earth return vehicle “Chang’e-5” to collect the local soil.

“Changzheng-5” refers to the basic Chinese family of rockets, named in honor of the legendary long March of the Communists in the Civil war in China. “Changzheng-1” was created on the basis of a ballistic missile with a nuclear warhead “Dongfeng-4”, launched in 1970 the first Chinese satellite. In fact, from this time begins the history of taikonautti – space Chinese.

However, prior to the 1990-2000-ies the development of the Chinese space was neither good, nor bad. And only in the last 10-20 years there was a serious success. But the speed of development was downright cosmic. Continue reading

The region of formation of comet Tempel 1 and the model of solar system formation

“Our observation was aimed at studying the chemical composition of the comet Tempel 1,” says Michael Mumma (Michael Turner) from space flight Center NASA Goddard (NASA Goddard Space Flight Center). The Mumma and his colleagues used a powerful telescope, the Keck Observatory in Hawaii for a detailed analysis of the light emitted by the gas of the comet at the moment of impact. Since each type of atoms and molecules has its own characteristic frequency of radiation, on the basis of this, scientists were able to determine the chemical composition of the comet’s nucleus.

Comets are blocks, which consist of ice and dust that move in elongated orbits. It is believed that the nucleus of the comet is gas and dust formations, remaining after the formation of the main bodies of the solar system.

When approaching the Sun, its radiation heats the comet’s nucleus, releasing dust and gas. The latter form a coma (cloud around the nucleus) and one or more tails. Repeated heating leads to the fact that disappear from the surface of the substance having a low boiling point. In fact, the nucleus of a comet is formed “crust” that is different chemically from its internal regions. This makes it difficult to determine the true composition of the comet just by studying the gas in its tail. Continue reading
