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

Space tourists threat?

Recently a team of American researchers said that the now popular space tourism can be dangerous for climate of the planet. However, many scientists refer to this statement with skepticism. My opinion on this subject the correspondent was expressed by one of the leading experts on space travel, Professor Alexander Bolonkin.

Recently the journal Geophysical Research Letters has accepted for publication an article in which a group of researchers suggests that the currently popular space tourism can be dangerous for climate of the planet. Although it is not yet printed, about this study already talking in many leading online publications. All of the authors of the publications seem to fully support the researchers ‘ view regarding the danger of space travel.

What a project to promote space so scared of scientists from the Aerospace Corporation in Los Angeles (USA)? The fact that, in their view, flying back and forth space “shuttles” are left in the upper atmosphere is a lot of soot, which is a product of incomplete combustion of nuclear fuel. A group of researchers led by Martin Ross built a computer model of such contamination, based on information from business plans for space tourism in ha by 2020, and emissions estimates developed spacecraft SpaceShipTwo company Virgin Galactic’s.
