5 unknown facts from the life of Konstantin Eduardovich Tsiolkovsky
On September 19, 1935 in Kaluga passed away the great Russian inventor Konstantin Tsiolkovsky . Exactly one year later there was opened house-Museum of scientist-taught and a pioneer of cosmonautics, whose life with her careful study expands like the universe.
1. Opponent of Einstein, an admirer of Lenin
However, the Tsiolkovsky-the theory of expansion of the universe was denied, as he denied the theory of relativity . Konstantin Eduardovich did not agree with Einstein that the universe is limited in size to two hundred million light years. According to Tsiolkovsky, the claim is as absurd as to assert that in the cross section of the universe equals one millimeter. Continue reading
NASA begins screening astronauts for Mars mission
The U.S. national Directorate of Aeronautics and space research (NASA) announced the launch of the program for the selection of astronauts in preparation for a manned mission to Mars.
The names of the astronauts will be announced in mid-2017. However, selected do not immediately fly to Mars, and will to participate in the testing of manned spacecraft Orion developed for Mars mission, which will take place no earlier than 2020.
While not everyone will be able to qualify for participation in the project. Mars offered to fly U.S. citizens with education below the bachelor’s degree in engineering, biology, physics or mathematics. Candidates must also have at least three years of experience in the profession or to provide evidence of at least a thousand flight hours as commander on a jet plane.
In addition, candidates will undergo testing at NASA physical endurance and tolerance to long-duration missions, the report says. Continue reading
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
