In today's 23 / 9, a satellite expired Agency Aerospace America (NASA) will break down to earth a day earlier than expected.
The case has really caused people in many countries fear debris from man-made device will hit the people, despite NASA's calculations show that a person is likely the meteorite hit just 1/3.200 .Mathematically speaking, it means you are likely debris fell on the only 1 / 21 trillion, while the possibility of lightning is 1/60.000 you.
NASA's UARS satellite crashed into the earth. |
But not the world record of never being someone's debris hit the satellite people. In 1997, Ms. Lottie Williams was a piece of the Delta II rocket the size of a soft drink fell on the shoulders in Oklahoma, USA. Fortunately she was unharmed after the accident that rare.
UARS satellite equipment is made of NASA's largest free-fall to Earth in 32 years. In 1979, deflected Skylad satellite orbit and crashed into the earth. Experts predict it will fall to South Africa but in fact, it flew into the Indian Ocean and western Australia. But there are no reports of injuries.
UARS welcome return this time can be seen as a rehearsal, because as expected, the German Rosat telescope size and greater weight will fall to Earth in November. Rosat giant lens will actually be a threat to people where it falls.
UARS is the space shuttle Discovery to orbit in 1991, with the task of measuring the number and atmospheric research. In 2005, UARS has officially expired and was abandoned after 15 years of NASA since its launch. Weighing more than 5 tons, UARS can not burn out as friction with the atmosphere in the process of return. So predicting where the falling debris of UARS has become urgent task for scientists to minimize potential damage to humans.
