TubeSat - your own satelite !Our planet has entered the next stage in the history of technology. This happened as a result of the invention Private TubeSat satellites tandbehandling i Polen Links patrocinados no Google www.performance-media.com.br (called Interorbital's TubeSat Personal Satellite Kit). Recent satellite TubeSat a modernized alternative to the CubeSat. The invention weighs only three quarters of the mass of its predecessor, which is 0.75 kg. Is also smaller volume of the device. Nevertheless TubeSet offers plenty of free space required for carrying out most of the experiments. What's more, at best, the price of Stag night Krakow incoming tour operator poland Free Phone Cards the set includes a cost TubeSat put satellites in orbit. For this purpose, use is made of Satellites NEPTUNE 30, which brings the device to the target. Due to the fact that the devices are placed on TubeSat orbits located at a distance of 310 km (192 miles) from Earth's surface, they are not on the "routes" waste of stag weekend krakow Hotels compare discount plastics space that could damage the device. After the period of their utility, which takes about a few months (the exact length of time that a satellite is in orbit depends on solar activity), the satellite re-entering the atmosphere and are burnt. TubeSats devices are "friendly orbits. Launch the first satellite is planned for December 2010. TubeSat device has been designed to fulfill the function of BSB (Basic Satellite), peru phone card china phone card Conference Organizers Poland or a mere satellite detached. In each set attached to the device you will find the technical elements of the whole satellite monitoring mechanism for the circulation of the satellite Gerber Files (PCBs), electronic components, solar cells, batteries, transceiver, antenna array, a microcomputer and software required. With all the elements, anyone can build their own satellite, which is able to generate energy, Incentive Travel Poland DMC Poland Otimizaçao de sites which is enough to locate it in the space around Earth from manual, almost amateur radio receiver.

This year, a swarm of Leonids may be active far-reaching as many as 200 meteors per hour. Until recently it seemed that the comet formed 55P/Tempel-Tuttle swarm of Leonids has its period of glory for himself. This comet returned in the next around the Sun in 1998, and by that in 1998-2002 we have seen rain meteor activity that reached up to 3000 events per hour. Theoretical models describing the evolution of the swarm of particles expelled from the comet 55P/Tempel-Tuttle over the past several hundred years, however, showed clearly that the year 2002 was the last, where we had a chance to watch the meteor shower real. Weak activity in 2003-2007 seemed to confirm these predictions. November 2008, however, he changed the situation somewhat. Earlier this month, Jeremie Vaubaillon predicted as many as two additional moments of increased activity of Leonids 2008. The first was to get out as early as the night of 16 to 17 November at 2:32, when the earth was to meet with the material ejected from the comet in the year 1466. Here were only two good messages. First, the moment was favorable for observers in our country. Secondly, the projected number of hours were to be in the range 25-100. It turned out that virtually Vaubaillon hit the jackpot. From the data presented on the International Meteor Organization revealed that most of the swarm of Leonids meteors can be admired in the night from 16 to 17 November at around 2:59 hours, so only less than half an hour later than the suggested models. In the case of such a difficult thing as a modeling streams, such half-hour shift in the way of precision is perfect. Moreover, although the predicted activity dating back 25 to 100 meteors per hour, proved to be true most optimistic forecasts. In fact, we had maximum opportunity to admire as much as 95 events per hour. In September Vaubaillon published the results of its latest model. From these calculations show that on 17 November 2009, we have a pretty big chance of activity, due to the fact that the earth will meet with the two traces of dust from the comet's mother dumped in 1466 and 1533. Moreover, the meeting will more or less at the same time, the first trace at 22:43 our time, and the second about 22:50. The submission of these two maxima can give the number in excess of 200 meteors per hour. Vaubaillon does not exclude, however, that as in 2008, the maximum shift for a moment about half an hour or even an hour later. It would be useful for observers in Poland, because the radiant swarm (the place from which the meteors seem to fly out) located in the constellation Leo, at the end of the night rises higher and higher above the horizon. The projected time is radiant because only 10 degrees above the horizon, but an hour later more than 15 degrees. The model provides a Vaubaillona appearance of two weak maxima. The first of these is associated with particulate trace left behind by the comet in the year 1567 and to meet with him come November 17 at 8:27, so when unfavorable for observers in our country. The latter appears on November 18 at 4:29, so the ideal time for us and will be associated with very old material from the year 1102 The model speaks of activity at the level of 10-50 meteors per hour. This year, a good guide to where to look for the constellation Leo, and lying in the swarm will be clear radiant Mars, which shines on the border of the constellations Leo and Cancer, a little above and to the west of radiantu Leonids. It should be noted that the next new moon falls on 16 November, and thus create ideal conditions for observing Leonids, which can be seen on the dark sky, allowing even the weakest record the phenomenon. May the weather was good, and the maximum was delayed even more than an hour - said PhD. Leonids are active from 10 to 23 November and are the fastest meteors known to us. The particles that fall into the stream because the earth's atmosphere at breakneck speed of 71 km / s. |
