The "Venera-D" on the study of Venus will realize in 2020-2025- VIDEO
Monday, 08 October 2012 14:44


The head of Roscosmos (the Russian Federal Space Agency), Vladimir Popovkin, on the third Moscow International Symposium on Solar System Research in Moscow, said today, that the project "Venera-D" to study of Venus, the Roscosmos plans to realize in 2020-2025. According to Vladimir Popovkin, the "Venus-D" implies a large-scale studies with Venus orbiter, two balloon probes, as well as the device, which falls on the surface of Venus. It is assumed, that the orbiter project of "Venera-D" must have worked in an orbit of Venus at least three years, sending all information to Earth, THE VIDEO: http://hainanwel.com/en/unusual-world/2 ... venus.html

"Venus Express" will enter into the atmosphere of Venus- VIDEO PDF Print E-mail
Monday, 19 May 2014 13:02
The European Space Agency is preparing to conduct an interesting experiment: brake apparatus "Venus Express" by the descent into the Venusian atmosphere, without using expensive missiles. After eight years of study of the second planet in our solar system, "Venus Express", the unit of the European Space Agency (ESA), will enter the Venusian atmosphere in the next two months. According to the ESA, the work of "Venus Express" came to an end as its rocket fuel is nearly exhausted. The last mission of the unit will be to study the Venusian atmosphere close during flight through it. On the "Venus Express" are located seven high-precision instruments for a detailed study of the ionosphere, atmosphere and surface of Venus. The device was launched on November 9, 2005 from the Baikonur Cosmodrome, using rocket "Soyuz-FG". In April next year, it was already on the 24 -hour elliptical orbit of neighbor of Earth, flying at an altitude of 66,000 km above the south pole of Venus and only 250 km - over the north. During his eight-year career apparatus provided scientists with a wealth of new information about the Venusian atmosphere, the rotation of the planet, its magnetic poles and possible tectonic activity. Given that fuel reserves "Venus Express" coming to an end, ESA gradually begins descent apparatus into the atmosphere. One of the goals of this maneuver - getting valuable experience in the art of aerobraking, that will be used in future missions. ESA is going to slow down the machine lowered without using expensive missiles. Experiment on aerobraking will be held sometime between June 18 and July 11, with the devices unit will continue to receive and process data about the planet's atmosphere. Experts are not sure, that survive of the "Venus Express" will be a similar test. If so, its mission is likely to continue for several more months, VIDEO:

Venus Express spacecraft plunged into the upper atmosphere layers of Venus - VIDEO

Thursday, 17 July 2014 08:00
Venus Express spacecraft from the European Space Agency plunged into the upper atmosphere layers of Venus during its descent from 160 to 130 kilometers. During this immersion in the atmosphere of Venus, the Venus Express found a thoUSAndfold increase in the density of the atmosphere of Venus. Later apparatus Venus Express will rise to a higher orbit to an altitude of 460 kilometers before July 26, 2014, VIDEO:

Apparatus Venus Express has completed a dive into the lower layers of the atmosphere of Venus- VIDEO
Apparatus Venus Express, which was made by the European Space Agency to study Venus completed a dive into the lower layers of the atmosphere of Venus and safely got out of them. Apparatus Venus Express to the end of July 2014 studied the red-hot atmosphere of Venus at a distance of 135 kilometers above the surface, examining the strata of the atmosphere of Venus, that were not available previously. During the investigation it was found that the atmosphere of Venus in the band from 130 to 165 km above the surface, the pressure is about 1000 times greater than in the higher layers of the atmosphere of Venus, VIDEO:

Venus may have oceans of carbon dioxide - VIDEO

Venus is often called Earth's twin because it is the rest of the world more similar to Earth by weight, size, distance from the Sun, and chemical composition. Nevertheless, even though the Earth is a haven for life, Venus appears hellish planet with a terrible atmosphere and clouds of sulfuric acid, caustic that harbor desert, hot enough to melt lead.

Although Venus is now extremely hot and dry, once on it could be oceans on Earth. Previous studies have suggested that in the atmosphere of Venus is enough water to last it could cover the planet ocean depth of 25 meters - if all this water somehow fell as rain. But the planet is too hot water has cooled down and settled, in spite of its volume.

Instead, the water of the seas, scientists have suggested that Venus once could have in Oceania from liquid carbon dioxide. Carbon dioxide is abundant on Venus.

"At the moment the atmosphere of Venus is represented mostly carbon dioxide, 96.5% of the total," - said study author Dima Bolmatov, a theoretical physicist at Cornell University in Ithaca, New York.

Carbon dioxide is well known to the world as a greenhouse gas that traps heat, warming the planet, is exhaled by animals and used by plants during photosynthesis. Although this substance can exist in solid, liquid and gaseous form, at a certain critical point, combining temperature and pressure, carbon dioxide can pass in "supercritical" state. It can have the properties of both liquids and gases. Dissolving metals like a liquid, but the flow, like a gas.

To see what might be the effects of Venus with supercritical carbon dioxide Bolmatov and his colleagues studied the unusual properties of this substance. Such substances, scientists still know little.

It is usually assumed that the physical properties of supercritical fluids are gradually changed along with pressure and temperature. But computer simulation of molecular activity showed that in the supercritical state such matter can dramatically shift from gas to liquid properties.

The atmospheric pressure on the surface of Venus now 90 times higher than on the earth. But in the early days of the planet, this pressure could be ten times higher. So could last a relatively long time, from 100 to 200 million years old. Under such conditions, the carbon dioxide could be formed into a supercritical fluid behavior, said Bolmatov.



"This, in turn, makes possible such geological features of Venus as gorges and valleys, like the mouth of the river area, plains and prints other activities similar to the supercritical carbon dioxide fluid," - said Bolmatov resource Space.com.

Scientists have found that depending on the pressure and temperature of the cluster gas-supercritical carbon dioxide (Michael D1) could be collected in the "bubbles" of gas, covered with a thick layer of liquid.

Bolmatov and his colleagues are going to conduct experiments that will determine when the transition from gaseous to liquid properties of the carbon dioxide in the supercritical state.
