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
“Transition to transformation”
Humanity seems to have stayed in their home Solar system. Of his burning desire to go to other stars, scientists said at a scientific conference, held in October in Houston (Texas, USA ). Experts discussed the most grandiose project of the century – “Centennial spaceship” (“100-Year Starship”, or 100YSS ).
– Despite all the technological advances of humans, in the field of space exploration we’re on the level of cave people, – assured the leader of 100YSS Mae Jamison. All we did was hang a station in earth orbit, where just sometimes come to live people. The main task of space exploration in the long term should be the creation of colonies, which can live people.
The project was launched by the defense advanced Agency research projects U.S. Department of defense (DARPA) to explore all possibilities of distant travel. Help them specialists from the Research center named Ames, one of the main research laboratories of NASA. Scientists believe that their dream will come true within the next 100 years.

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
