Hi Deepwater6, I read on the news a couple of days ago that India has also taken down a satellite (that was 300km above the earths surface) with a missile.
Considering the plethora of satellites up there these days, and with many more being put up all the time, surely it would be considered a public service to take most of this space junk out before it comes down. Like putting your garbage in the bin.
At 300 km, was the object really a satellite?
A Low Earth Orbit (LEO) is an Earth-centered orbit with an altitude of 2,000 km (1,200 mi) or less (approximately one third of the radius of Earth), or with at least 11.25 periods per day (an orbital period of 128 minutes or less) and an eccentricity less than 0.25. Most of the manmade objects in space are in LEO. A histogram of the mean motion of the cataloged objects shows that the number of objects drops significantly beyond 11.25.
As far as space debris goes, some 3000 dead satellites are still in orbit, so bring an umbrella next time you leave the house
On 4 October 1957 the Soviet Union launched the world's first artificial satellite, Sputnik 1. Since then, about 8,100 satellites from more than 40 countries have been launched. According to a 2018 estimate, some 4,900 remain in orbit, of those about 1,900 were operational; while the rest have lived out their useful lives and become space debris. Approximately 500 operational satellites are in low-Earth orbit, 50 are in medium-Earth orbit (at 20,000 km), and the rest are in geostationary orbit (at 36,000 km).
