Recently the world celebrated the first 50 years of human space flight. And now, after half a century, this date should be remembered, because in space, traveled more than five hundred people from many countries, including from Ukraine.
Fidel Pavlenko said Oleg Fedorov, Director of the space research Institute of NAS of Ukraine, whether to continue to consider, on 12 April an outstanding day in the history of mankind?
Space activity is not profitable. It is of course. But we understand that there is a space of 40 Nations with a space program, and even in the crisis public investment has not decreased, as far as I know. This suggests that many countries consider that such activity for us today it’s not profitable, but, as the Americans say – investing in the future.
It seems to me that every civilized man, who forgets the beginning of its activities or the activities of its predecessors, not like this. So one who is engaged in space activities, even for him this is not only a celebration, an occasion to reflect every time on what you do today, what path was and what is waiting for you. Therefore very important for us because this date is once again to think over the strategy. Continue reading
Two Muscovites may well go to Mars. However, only after nine years. And in case of successful realization of the international project Mars One. Candidates for the expedition were selected around the world, and now they will be ready to fly to the eyes of billions of spectators.
For her, it seems, nothing is impossible. It conquers the caves and the mountains, descends into the water and in free flight, as a bird soars above the ground. However, psychologist and fitness trainer Catherine thinks Elias is only the stages of the path. Into space. To Mars. She’s seriously going to be among the first inhabitants of the red planet.
Fascinated fantastic novels, and Bradbury, Strugatsky, the journalist Anastasia Stepanova on distant planets, too, dream of a lifetime. After work in a hurry for courses in basic space Sciences. And even spent two weeks in the desert, in conditions resembling Martian.
Such take in cosmonauts. Anastasia and Ekaterina participating in the project MarsOne. Its creators two years ago announced, Mars will finally have a life. Will founded the settlement of earthlings. Continue reading
Jupiter thousands of years ago named after the king of Roman gods, and reigns among the nine planets of our Solar system, rivaling the Sun in its splendor. The largest planet is located far beyond the main asteroid belt. The mass of Jupiter exceeds the mass of all other planets combined.
Jupiter is the largest planet in the Solar system. The semimajor axis of Jupiter’s orbit is 5.2.e. the eccentricity of the orbit e = 0,0489, the period orbits – 11,867 years. The inclination of the orbital plane to the plane of the Ecliptic is 1°1817″. The average speed along the orbit – about 13.1 km/s.
The period of rotation around the axis is 9 hours and 55 minutes. Each dot on the equator moves at a speed of 45 thousand miles per hour. Due to the centrifugal force of Jupiter is noticeably flattened (compression rate greater than 6 %). Since Jupiter is not a solid ball, and consists of gas and liquid, the Equatorial parts rotate faster than the polar regions. The rotation axis of Jupiter is nearly perpendicular to its orbit, therefore, the planet has no seasons.
The mass of the planet is M = 318 M = 1,9∙10 27 kg, radius R = 11,2 R = 71 492 km, However, Jupiter is very thin: its density is 1.33 g/cm 3. which is four times less than the density of the Earth. The acceleration of gravity at the level of the cloud surface of Jupiter sostavljaet = 2,53 g. Continue reading
