U.S. robot rover Spirit, a geologist at the nature of the job, he lost a hard struggle for survival on Mars! NASA is evening at 19 o'clock our time, and officially announced he is giving up on further efforts to save the rover. We tried everything that was in our power over the past eight months. We did not succeed. Spirit is now going through the last week before the performances strong winter in the southern hemisphere of Mars, where it is located.
But that does not mean that the Spirit is dead now, and now, said Doug McCuistion, director of NASA's Mars Exploration Program. Over the next four weeks engineers and mission planners will try to prepare for the weak rover Mars long winter. He now receives only about two hundred watts of power your solar panels (nominal capacity of over 800W) and will soon reach the lower critical limit of only 100-odd watts, you must be in hibernation. The remaining days of the life of NASA's Spirit will use as a stationary research station, and success in the draw that was almost within reach of past days ..
Attempts to pull the rover out of sand traps into which he fell in May last year have yielded no results for months. Moreover, the rover is more and more ukopavao instead of getting out. However, the last trials showed a significant improvement! Rover is built from the ground and several inches of progress made by driving backwards. It's a shame that we have still a few weeks time, hope to pull it out this time they were justified, considered by NASA.
Spirit was originally intended to hold on Mars for three months, the deadline is exceeded for more than five and a half years and had come to an end. Robot geologist has found evidence of the former existence of water on Mars, and one of the most important discovery is considered to be the discovery of some fine sand structures on the Earth is we can not produce in the laboratory. What an irony it is precisely this discovery apparently stood head. When the battery power falls below a critical threshold, the NASA rover to sleep. Months would pass without any way of communication with Earth, and if it ever occur. Spirit arrived at the end of his career.
To determine if indeed a miracle and very sick (read: corrupt) Spirit survives the winter, the spring would pull its continued operations. But such a scenario is virtually unheard of.
Meanwhile on the other side of the planet, Spirit's twin Opportunity is in good condition and continues to study the plan. And the two spacecraft orbiting Mars just listen to radio signals in the hope that it will hear a faint signal with the resurrection of Mars Phoenix Lander's Mars where ice was too heavy for winter survival.
