SPACECRAFT ( SC ) is a technical device used to perform a variety of tasks in space. as well as conducting research and other works on the surface of various celestial bodies. Means of delivery of spacecraft into orbit serve as launch vehicles or aircraft .
Spacecraft, one of the main objectives of which is to transport people or equipment in the upper part of the earth’s atmosphere — the so-called near space. also called “Space aircraft” ( CLA ).
The use of spacecraft to determine their separation in the following groups:
suborbital SPACECRAFT ;
earth orbital SPACECRAFT . moving on geocentric orbits of artificial satellites ;
interplanetary (expeditionary) SC ;
napolnenie KA . Continue reading
Giant spaceships approach the Earth?
The recent statement by scientists from SETI (the project engaged in the search for extraterrestrial intelligence) is not a joke stirred the public. Once the U.S. government decided to stop funding SETI, the researchers of this organization released information that they were able to detect several huge objects of unknown origin near the orbit of Pluto is rapidly approaching our planet. Assume that these objects are concentrated in the field of length 150 and a width of 30-50 miles. Also refer to the coordinates with the location detected UFO:
19 25 12, -89 46 03
16 19 35, -88 43 10
Scientists are unhappy that the government is trying to hide such important information from people.
There are rumors that these ships are here to save humanity from the terrible disasters that can occur on Earth in the near future, performing the role itself is a kind of Ark. There is also the view that we are on the verge of star wars, and these objects have come to enslave the inhabitants of the Earth.
Many reputable scientists say that this story is nothing like another invention of the SETI, but really it’s just piles of debris. Continue reading
Only on our channel we Represent your attention the biggest planet of the solar system. And let’s talk about Jupiter in more detail
The largest planet —- (0012) —- the Size of Jupiter —-
Jupiter is the biggest and the heaviest planet in the Solar system located far beyond the main asteroid belt.
According to modern concepts, the sun and the planets formed from a common dust cloud. The share accounted for 23 of Jupiter mass of the total mass of the planets of the Solar system. Its mass is 2.5 times greater than the mass of all the combined planets of our Solar system. Where the planet consists of hydrogen, methane and ammonia.
—- (0031) —- Facts about Jupiter —- The largest planet —-
Jupiter is so thin that its density is 1.33 gcm3, which is four times less than the density of the Earth.
The acceleration of gravity at the level of the cloud surface of Jupiter is g = 2,53 g.
This planet has a powerful magnetic field, about 67 satellites of the ring. Continue reading
Space tourism. History and prospects.
On Friday, 31 October, disaster struck the American private spacecraft Space Ship Two. This is the news went around all the news channels of the world. One of the two pilots managed to eject.
What kind of project passenger space ship Space Ship spaceship and carrier White Knight ?
For the first time the issue of commercialization of space missions was raised as far back as 1967, the Americans. But the idea found no support in the state. Space flights were very hazardous and the road.
However, in 1996, well-known, tireless designer, inventor and pilot Bert Rutana was established by a private design company to create space, passenger craft reusable. Commercial use of space travel received a new impetus. The concept of “space tourism” takes on a new, broader meaning. Of course, later were space tourists. They were sent to the Mir station, the Russian Soyuz spacecraft. But, first of all, it cost millions of dollars, and secondly, these were isolated cases, and on tourism, in a broad sense, could not be and speeches. The program was funded by large companies or the flight was paid for by private individuals. Continue reading
It has long been observed that the nuclei of periodic comets are depleted, with every turn they glow weaker. Not once was there a division of cometary nuclei into two parts or more. This destruction produced or solar tides, or collisions with a meteor shower. The comet, discovered by the Czech scientists Bilim (Biloy) in 1772 was observed with repeated returns with the seven-year period. In 1846 its core collapsed, and it turned into two weak comets, which after 1852 was not observed. When in 1872, according to the calculations, the missing comet should pass near the Earth, there was rain of “falling stars”. Since November 27 this phenomenon is repeated every year, though less effectively. Small solid particles of the disintegrated nucleus of a former comet Bilogo stretched along its orbit, and when the Earth crosses the stream, they fly in the atmosphere and evaporate. A number of other meteor showers.
Meteoroids — the remains of comets, visible only at the time of evaporation are called meteors. The width of meteor showers is much greater than the size of the generated nuclei.
Photographing the path of the same meteor in the starry sky, as he is projected to observers, separated from each other by 20-30 km, determine the altitude at which the meteor appeared. Most meteoroids begin to glow at heights of 100 to 120 km and has already completely evaporated at a height of 80 km . Continue reading
