On December 6, 1999, following a failed connection with NASA’s Mars Polar Lands who planned to land in the South Pole of Mars, NASA had to admit that this massive exploration program, along with a staggering $ 165 million soup. This means that in less than three months, two Mars spacecraft were bad luck. Although the cause of the error has not been ascertained, the Mars Climate Probe that burned over Mars on September 23 was purely a low-level mistake: the manufacturer used the British system, but NASA scientists thought it was a metric system , So that it landed at a height of 60 km - at that altitude, the atmosphere of Mars has been quite dense, the spacecraft can not withstand the severe friction ...
