Through thorns to the stars will leave a “100 year spaceship”

“Transition to transformation”

Humanity seems to have stayed in their home Solar system. Of his burning desire to go to other stars, scientists said at a scientific conference, held in October in Houston (Texas, USA ). Experts discussed the most grandiose project of the century – “Centennial spaceship” (“100-Year Starship”, or 100YSS ).

– Despite all the technological advances of humans, in the field of space exploration we’re on the level of cave people, – assured the leader of 100YSS Mae Jamison. All we did was hang a station in earth orbit, where just sometimes come to live people. The main task of space exploration in the long term should be the creation of colonies, which can live people.

The project was launched by the defense advanced Agency research projects U.S. Department of defense (DARPA) to explore all possibilities of distant travel. Help them specialists from the Research center named Ames, one of the main research laboratories of NASA. Scientists believe that their dream will come true within the next 100 years.

Inside the comet 67P found large voids

Inside the comet 67P/Churyumov — Gerasimenko there are no large voids. The mission of “Rosetta” the European space Agency made measurements that clearly demonstrated and solved the old mystery. Comets are icy debris left over from the formation of the planets 4.6 billion years ago. Spacecraft have visited a total of eight comets, and through these missions we pulled a picture of the basic properties of these space-time capsules. On some questions the answers were found, others appeared.

Comets, as we know, consist of a mixture of ice and dust, and if there were compact, gravity superior to water. However, previous measurements have shown that some of them have very low density, much lower than water ice. Low density means that the comet must be extremely porous.

But what is this porosity: due to large voids in the subsurface of the comet, or due to a more homogeneous structure with low density? Continue reading

Space price war between Russia and SpaceX

American capitalism against Russian capitalism

Recent actions taken by Congress to limit the use of Russian rocket engines in order to ensure national security, has made a real revolution in the American commercial space research programme. Private companies, such as “SpaceX and Blue Origin and Aerojet Rocketdyne” we intend to introduce a NASA rocket engines of domestic production.

Meanwhile, Russian President Vladimir Putin has abolished Russian Federal space Agency, replacing “Roscosmos” new Corporation “will be to independently develop new spaceships and implement new projects.”

However, those who thought that the Russian space industry was held the victory of capitalism, is fundamentally wrong. Unlike the company “SpaceX”, which is a fully private enterprise, updated and modernized “Roscosmos” will be one hundred percent owned by the Russian state.

The establishment of full control over the space programme is, with toccatina Putin, way to control expenses and prevent corruption. Continue reading

Size comparison of Planets and Stars

Comparative sizes of some well-known space objects

Surely everyone at least once in my life come across another list of natural wonders, which lists the highest mountain, the longest river, the driest and the wettest regions of the Earth and so on. Such records are impressive, but they fade tightly in comparison with the sizes of space objects. Here’s to them we will now see.

Mercury is the smallest planet of terrestrial group. The radius of mercury is 2439,7 + 1,0 km 0,055 Mass of the planet earth. Area 0,147 earth.

Mars is superior in size only to the mercury. The mass of the planet equal to 10.7% of the mass of the Earth. Amount equal to 0.15 volume of the Earth.

Venus is closest to Earth on the indicators. The orbital period of 224.7 earth days. Amount equal 0,857 earth. Weight-0,815 earth.

The ground – fourth in the list of largest after mercury.

Neptune – mass Neptune bigger than Earth at 17.2 times. Continue reading

Models of 3D and 2D Solar system

FLASH model of the Solar system convenient for the development of ideas about the Solar system. IN 2D

On this model You can clearly see and understand what the Solar system. Flash animated model, we can consider the motion of the planets not only in the absolute coordinate system, but in relative.

Top left is the lever to change the speed of rotation of the planets (including negative). Beautifully highlights the important points on this model. You can also turn on the music if you need music background.

The lower left of the moon phase. Helps in clarity.

At top right You can enter a specific date, say a birthday, and to get the position of the planets at the moment. Just below the switch between the months and the constellations, walking on the edge of the circle.

Bottom right switch astronomical systems of perceiving the world. Continue reading
