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

The greatest hoax in the history of space exploration – Secrets of the world

Space exploration mankind is just beginning. It’s only been 47 years since the launch of the first artificial satellite. At the dawn of the space seemed to fly on the next planet there are very few. The great powers of the world tacitly competed for the right to be the pioneers of space. As you know, the palm in this area belonged to the Soviet Union first launched into space man.

After the launch of Yuri Gagarin the world community recognized the absolute leadership of the USSR. But the main competitor – the United States of America – was not shared by the tumultuous enthusiasm about another giant leap of progress. And if the Soviet Union existed, the phrase “Catch up and overtake America!”, before members of the NASA task was to restore the eroded national prestige ahead of the Soviet Union in the space race. Three weeks after the flight of the first American astronaut in space, John F. Kennedy vowed America, after ten years since the Americans landed on the moon.

Indeed, on July 21, 1969 American astronaut first stepped on the moon. For Americans, this event was no less significant than the discovery of America or the Declaration of independence. Around the globe spread the pictures depicting the first inhabitants of the moon under the stars and stripes, and later shots of the film depicting a historic moment. With them and began don’t setaside this time the dispute about the lunar program. Continue reading

Philae returned the first detailed images of the comet Churyumov-Gerasimenko

Wednesday night, the Earth reached the signal from the research module Philae successful landing on the comet Churyumov-Gerasimenko. Unique in its complexity maneuver succeeded at the first attempt. Experts from the European space Agency outfitted the robot in the path 10 years ago. During this time the device has traveled more than six billion kilometers. The data collected, according to scientists, may shed light on some puzzles of the Solar system.

Almost 7 hours of intense expectation, and now scientists from the European space Agency’s congratulate each other with applause. The descent module landed on the comet. Or, saying a new term, “picometers”.

“Undoubtedly, we have lived this mission for 10 years. And now the goal has been achieved. Philae landed on the comet surface. We clearly saw it on the testimony of telemetry”, – reported in the ESA.

“Philae is talking to us. It comes from all the new data that we process right now. Continue reading
