Inside the comet 67P found no major voids

Interested in everything connected with high technologies.

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

Open planet in honour of Day of Astronautics

One day in April Gagarin made his flight, and today we are on such a universal scale occasion will transcend time and space.

Time is not linear, reality is relative, and can simultaneously be in two different places. To prove it, in our current cultural ranking, we sort of go back in time to learn about the future. With undying love for “the Martian Chronicles” and warm memories of childhood on the theme of Kir Bulychev’s works we decided this time to make more distant and mysterious space journey, revealing along the way a couple of other unknown planets. So, the first point of our sci-Fi trip -1938 year.

The asteroid Vesta, around the Main asteroid belt

In earth time: 1938

Discoverer: Isaac Asimov, “In the thrall of Vesta”

What happens:

Three space travellers, survivors in the crash of a spaceship. Three airtight rooms, one spacesuit, three days ‘ supply of oxygen, a week’s supply of food and a year’s supply of water… Continue reading

Galactic tourists

100 kilometers above the Earth’s surface (according to the international standards space begins at this altitude), speed – kmh 4000, which is 4 times the speed of sound, so it looks like a tourist flight into space, which you could see in sci-Fi movies or dreamed about since childhood.

Now the dream to see the immensity of outer space has already become a reality.

Who are those 5 people who first saw the Galaxy, read the article. We will also talk about the details of the flight and to quote the impressions of space explorers.

Space tourists – Dennis Anthony Tito

Time in space: 28 April – 6 may 2001

Fare: $20 million

Citizenship: United States

This reckless American with a decidedly non-American name proudly bears the title of “space tourist No. 1”. Anthony Tito is a multimillionaire and entrepreneur of Italian origin. Continue reading
