Space pollution reaching zenith
Next time your brand new telescope traces something in the space, don’t get elated assuming a new discovery. You might have just located an iota of garbage that has littered the space above us. Starting with Sputnik 1 in 1957, more than 4,000 satellites have been sent to space. Since then, it has been reported that more than 70,000 objects lie spread between 850-1,000 km above the Earth. With an impact speed of around 36,000 kilometers per hour in space, it is estimated that a 1mm metal chip can match the lethality of a .22 calibre rifle (a metal of the size of a tennis ball is as fatal as 25 sticks of dynamite).
A National Geographic report says that NASA regularly replaces some windows of its space shuttles (as they get damaged) by small particles in space.Space debris need not remain in space and can regularly fall on earth. The Delta rocket dropped on earth on January 22, 1997 in Georgetown. Similar incidents have happened in Saudi Arabia, Argentina & Brazil. With the Centre for Defence Information stating that space debris is increasing at the rate of 5% per annum, we might someday have a huge space debris layer instead of the ozone layer surrounding the earth. And as our lives get more dependent on satellites roaming in the infinites, damages to them by the roving bullets can’t be ruled out.
