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

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
