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

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

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

Cosmonauts day

April 12, Russia celebrates cosmonautics Day. This holiday was established by the decree of the Presidium of the Supreme Soviet on 9 April 1962 in honor of the world’s first manned flight into space.

April 12, 1961 in earth orbit was launched the world’s first spaceship‑satellite “Vostok” with a man on Board. The launch of the first manned space craft was headed by Sergei Korolev, Anatoly Kirillov, Leonid Voskresenskiy.

Pilot‑cosmonaut of the ship was a Soviet citizen pilot major Yuri Gagarin. The start of the space multistage rocket was successful and after the set speed and separation from the last stage of the carrier rocket, the ship began a free flight on an orbit around the Earth.

After circling the globe, through 108 minutes after launch, was included braking propulsion system and the spacecraft‑the satellite began to descend from orbit to landing. In 10 hours 55 minutes Moscow time the astronaut landed in a given area of arable land in the Volga river near village of Smelovka in the Ternovsky district of the Saratov region. Continue reading

Commercial space station
Second disclaimer: Denis Tito was the first cosmotourist, but not the first astronaut sent into orbit on a commercial basis. Even in 1990, Japanese journalist toyohiro Akiyama visited the orbital…
