You must have heard of collisions and accidents on roads ,water or air. But you will be amazed to know that there can be accidents in Space also.

For the first time in this Space -Age , two satellites have collided in orbit. Early on Wednesday morning, Sydney time, a Russian communications satellite and an American Iridium mobile phone spacecraft smashed into each other, 790 kilometres above Siberia.

This left both the satellites unusable . US Air Force Brigadier General Michael Carey, of US Strategic Command, said at least 600 pieces of wreckage had been observed circling the world.

“We knew this was going to happen eventually,” said Mark Matney, of NASA’s Orbital Debris Program Office.

Orbital traffic control had been impossible because the position of most satellites, until now, could only be plotted to an accuracy of four of five kilometres.

Yesterday, NASA was trying to determine whether the wreckage posed a danger to other satellites. Initial findings showed the risk to the International Space Station was “very, very small”.

The 900 kilogram Russian satellite, Cosmos 2251, was launched in 1991 and ended its working life 10 years ago. The 670 kilogram American vehicle was one of 66 operational Iridium spacecraft relaying satellite-telephone communications.

NASA says about 17,000 objects bigger than 10 centimetres, mostly debris from satellites and rockets, circle Earth.

This is high time now to take a look at the space debris also.Otherwise it may cause serious damage to our future palns of space flightsor telecommunication plans…
