Planet For Harvest Kepler

The astronomical community is undoubtedly a revolutionary moment in the field of extrasolar planets. NASA officials have made new findings provided by the Kepler observatory, and among the large number of planet candidates (yet to be confirmed), begin to emerge those of land size, and even better, which are at distances from their star support the existence of liquid water on their surfaces, ie, that might be suitable for some form of life. The Kepler is reviewing systematically heaven, but only a small part of it, so that the potential number of planets in the nearby universe promises to be huge. According to the latest news, Kepler has identified to date a total of 1,235 candidates for extrasolar planets. Of these, 68 would be the size of the Earth, 288 are called super-Earths, 662 are the size of Neptune, Jupiter 165, and 19 would be greater than the latter. The most interesting is that 54 candidates are in the appropriate "habitable zone" of its star, ie, they may have liquid water on the surface, and that of these, five are about the size of Earth, the rest being somewhat higher or much older. The latter could be equally habitable moons. The habitable zone has a variable position depending on the type of star. A small star will cool the area very close to it, and a very warm the take further. Scientists have also reported that six of the candidate planets found around a single star, Kepler-11, 2,000 light years from us. There are six planets that pass in front of its star (who made transits), and therefore the system could be even more unknown members. Kepler's work, however, has not finished at all. The results to date come from observations made from 12 May to 17 September 2009, which involved the review of the 156,000 stars in the field of view available, which covers 1 / 400 of the sky. About 170 of the stars seem to have more than one planet. Candidates may now become full-fledged planets if confirmed by observations from the ground and others made by the Spitzer Space Telescope.

's First Satellite Geo-IK-2 does not reach orbit Preview

space launch The fifth year could be the first to have failed. Russia launched from the Plesetsk cosmodrome at 14:00 UTC on 1 February, a rocket-KM Rokot a scientific military satellite on board. But the rocket left its cargo in an elliptical and not circular, as expected. It seems that the Briz-KM upper stage failed to fire again to bring the satellite to an altitude of 1,000 km planned. The satellite, called Geo-IK-2 (11L), is in a polar orbit, and so far has not contacted the Earth. Your goal should be to carry out surveying tasks (analysis of Earth's gravity, the rate of rotation of the earth and its shape), which would help to better understand our planet, plate tectonics and other useful features both for science and for the military. This first Geo-IK-2 (14F31) will be followed by a second copy within this year. Network is part of the Musson-2 and is a substantial improvement over the previous series Geo-IK. It was built by the company Reshetnev SS on a similar platform to the Uragan-M satellite. It has two solar panels and weighs about 1,400 kg. A board carries a radar altimeter Sadka provided by the European company Thales Alenia Space, laser retroreflectors GLONASS and GPS receivers. Russia has launched an investigation, pending contact with the satellite power and that can be pulled something out of him in his precarious orbit. ( Photo: SS Reshetnev )

The Discovery is back on the ramp of Launch

The shuttle Discovery left the vehicle assembly building at 19:58, when Florida (00:58 UTC), January 31, towards the launch pad 39A. The giant set, driven by the vehicle, and took about seven hours to reach its destination (07:53 UTC), about 5 km away. Once secured, the Discovery will begin to be ready for launch, scheduled for Feb. 24. ( Photo: NASA / Kim Shiflett )
