Soviet Probe ‘Cosmos 482’ crashes Indians after not under control of half a century ago | Science
Soviet probe Cosmos 482 It finally fell to the earth. After wandering The ship, which was launched in the framework of the mission in 1972 in 1972 by the orbit of the Earth, was outraged at the weather this Saturday, according to the Russian Space Agency Roscosmos, eight in the morning (Spanish Peninsular time). A. Telegram message, According to the Russian Agency, according to the Specialists of the Russian Center for Rockets and Space, saves Tisnimash, which is part of the Roscosmos, the device entered the atmosphere by 9:24 Moscow – the lowest hour in Spain – “Anaman Medio is 560 km west of the island.”
The main territorial agencies of the planet are following uncontrolled outrage over the Soviet investigation Cosmos 482 Although the expectations are being refined as the days and the planned date approaching, the uncertainty of the re -entry is high until the last moment of uncertainty. A few minutes later this Saturday morning, the radars of the Space Waste Office of the European Space Agency (ESA) found a ship on Germany. According to its instructions, the German country should come again at 9.30 am, but the radars have not grabbed nothing. “Since the radar ship on Germany was not found in this plan A blog There they monitor the re -entry.
Soviet probe Cosmos 482 It was a masterpiece released 53 years ago, it never reached its destination: Venus. This is the main reason for the fall of this object of space scrap for the earth. The ship is designed to bear the heavy pressure of the solar system’s warm planet, so it can live from one piece to its re -install in the Earth’s atmosphere, scheduled to Friday to Saturday.
The international committee’s supervision protocol was activated for space trash coordination a few days ago, in which 13 spacecraft besides ESA, its American Homologue, NASA, along with the United Kingdom, France, Italy, Russia, Ukraine, China and Japan. Despite the entire committee, communication between some of them is practically void. For example, it takes time without providing Russia’s data, although its radars are periodically followed by space objects. Provided a great information source to the Western world NASA With its radar network, both ESA and some European agencies have their own devices.
The uncontrolled probe completes an orbit every hour and a half. Each radar can observe this object four times a day and estimate when and where it falls. The problem is that it is very difficult to tolerate the behavior of this object in layers of atmosphere at a height of 100 and 200 km. For this, the uncertainty of solar activities and other unknown factors, as the parachute to the capsule, and if it is deployed, or if it is already done, Dormstadt, engineer Benjaman Bastida, who works in the ESA’s spacecraft in Germany, has explained. All of these factors were almost a day or later a day or later in the margin of the error, and almost all the earth was on the trajectory.
The Cosmos 482 It was opened in March 1972. It was unable to escape the less earthy orbit. After reaching the parking orbit around the earth, the ship tried to start the transfer trajectory to Venus. However, it was divided into four parts: two of them were in orbit in 48 hours in 48 hours, the other two pieces, perhaps the motor unit of the landing probe and the special upper phase, entered the high orbit of the earth’s 210 and 9,800 km, According to NASA. It is believed that the failure of the engine’s ignition is due to not reaching the speed needed to transfer the engine to Venus, leaving the payload in the elliptical terrestrial orbit, which will decrease over the next few days.
The 495 kg landing module is 300 times the acceleration of the terrestrial gravity and is designed to end up with 100 times more pressure than our planet, ESA describes. As a result, it can withstand its re -entry in the atmosphere.
Space agencies have been taken as a valuable experiment. The aerodynamic form of this ship makes it an ideal object to measure air density in very low earthly orbits. Every time the elliptical orbital orbit passes through the perigi, its nearest point loses the height of the earth, its highest part. This height difference allows you to cope with the climate resistance facing the object for re -entry. The design of a very space vessel is very complicated to perform these studies, but an almost spherical form of the descent cartridge makes it possible, making it a “accidental” scientific experiment with Rentrada’s entry.
The fall of large parts of space trash is common. Parts of moderate size rackets are outraged almost every day, but small objects of marked spacecraft waste are more frequent. Rarely surviving pieces can cause damage to the ground. With increasing space traffic, the frequency of these outrage is expected to increase in the future.
ESA explains that the risk of re -entering of the satellite is very remote that causes injuries. The annual accident of a person injured with space waste is less than 1 among 100 million.
