'How Many Satellites Are Orbiting the Earth? Essay\r'

'Satellites are tracked by linked States effect Surveillance internet (SSN), which has been tracking every object in orbit over 10 cm (3.937 inches) in diameter since it was founded in 1957. thither are approximately 3,000 satellites direct in solid ground orbit, according to the US bailiwick Aeronautics and Space Administration (NASA), by of roughly 8,000 man-made objects in total. In its entire history, the SSN has tracked more than 24,500 stead objects orbiting Earth. The majority of these have fallen into fluent orbits and incinerated during reentry. The SSN also keeps track which piece of quad junk belongs to which country. The SSN was founded in the wake of the install of Sputnik, the first artificial satellite, by the Soviet essence in October 1957. Orbiting the planet at 20,000 mph (32,186.88 kph) while emitting a eternal radio signal, Sputnik was a red gladiolus that told America not to take its technical dominance for granted.\r\nIn the following decade, the Space Race between the USSR and USA occurred, terminate with Apollo landing in July 1969. As lay technology matured, satellites were launched for military and commercial purposes. The value of satellite launches has dropped to as low as a few million dollars for lilting satellites, and a few tens of millions for heavy satellites. This put satellite technology within the stint of many nations and multinational companies. Satellites have an operating lifespan between five and 20 years.\r\nAs of 2008, the former Soviet Union and Russia had nearly 1,400 satellites in orbit, the USA approximately 1,000, Japan more than 100, China active 80, France over 40, India more than 30, Germany almost 30, the UK and Canada 25, and at least ten each from Italy, Australia, Indonesia, Brazil, Sweden, Luxembourg, Argentina, Saudi Arabia, and South Korea. The company Sea order †a consortium of four companies from the United States, Russia, Ukraine and Norway †has launched a few satel lites into orbit from international waters every year, although the company filed for failure in 2009. The largest man-made satellite before long in orbit around the Earth is the International Space Station. Some satellites, called microsats, nanosats, or picosats, can be as scummy as 10 cm (3.937 inches) in diameter and 0.1 kg (0.22 pounds) in mass.\r\n'
