In November 2006 Pavel Vinogradov hit the longest and fastest golf shot of all time. It would travel thousands of kilometers at 40 times the speed of a cruising jet. It may not stop travelling for three years.

   Vinogradov is not a golfer, in fact, he’s never played a round of golf in his life. He’s an astronaut, the commander of Expedition 13 aboard the International Space Station, orbiting the Earth. He played the short from a specially-built platform outside the space station during a space walk.

   The golf shot, breaking every distance and speed record in the history of golf, was eventually used in a TV commercial. The ball contains a transmitter and the journey of the ball could be followed on the website of the company that manufactured it.

  This is more than just a clever advertisement for a brand of golf ball, however. The space station also needs the publicity. The team of scientists working on the space propramme need to keep their work in the public eye, as they beg for extra funds to pay for their expensive reseach.

   But environmentalists are angry about this latest space prank  (恶作剧). “Space is already full of enough junk to fill an ocean,” said campaigner Rowan Conway. “Stunts like this are the last thing we need.”

   Since space exploration began, the USA has launched nearly 750 satellites traveling round space, and the former Soviet Union has launched nearly twice that number. China and Japan are responsible for another hundred or so between them. Even private companies have launched about a hundred.

   A lot of these satellites eventually stop working and start to fall apart. As a result, there are nearly 9,000 man-made objects hurting around in space, a lot of it’s debris(残骸碎片) and junk from long-defunct space missions. Space junk can be anything from a hatch which fell off a space module to a fragment of paint from the space shuttle or a satellite that no longer works. Thousands of nuts, bolts and other debris from space mission have created an orbiting garbage dump around Earth, presenting a hazard to spacecraft.

   Man-made debris can orbit at speeds of up to 28,000 kilometres an hour. Think of the damage a golf ball could do to a spacecraft traveling at that speed!
