It's like calling, if you wait a long time, the phone is still silent, then at a moment, no matter how reluctant the heart is, you have to put the phone down and hang up.

That's how NASA engineers and scientists feel on May 24, 2011. On this very day, NASA officially announced that it would end its daily routine call on Mars, which has fallen into

After a long assessment, NASA believes that in the absence of electricity, courage's aging electronic system is likely to have been destroyed in the severe winter cold on Mars, with little hope of resuming communications. In fact, this decision also marks the

Of course, the performance of courage has long been satisfactory to its development team, which is far beyond its original expectation: its original design life was only 3 months, but actually more than 20 times more than that, during which the courage was 7.7 miles on Mars, 10 times the design index. Above!

Courage and its sister rove

At the beginning of the mission, the software failed, but the engineers on the earth succeeded in repairing it remotely. But the most fatal accident of the spirit was in April 2009, when it passed through the sand. The engineer spent 8 months trying to save the courage, but failed.

In its jammed position, courage has no way to adjust its solar panel direction to the sun. As a result, it finally fails to survive the fourth cold winters on Mars. In March 22, 2010, the Spirit sent back the last signal, and then there was no news. The ground did not give up. NASA sent out the courage every day, hoping it could hear and answer, but without result. After more than a year, it was time to let go.



Engineers simulated the situation of courage in the laboratory, trying to find out the solution to the problem. Unfortunately, there was no successful source: NASA

The scientists judged that when courage lost its power, its
