“Curiosity” Mars probe landing will experience “7 minutes of terror”
According to United States media reports on July 11, Rover “curiosity”-August 5 will be landing on Mars, landing is not easy, however, any mistake can cause all previous efforts in vain. United States NASA (NASA) recently introduced the 7 minutes before landing, in a video that may occur, and refer to this period as “7 minutes of terror”.
According to this called the arrival of Mars’s challenge: “curious” 7 minute video introduction of terror, when the probe arrived at Mars, it must, within 7 minutes will be reduced from about 20,900 kilometers per hour to 0 in order to steadily landed. And because Mars to Earth of long distance signal transmission, researchers at the program on the planet will endure the grueling 14 minutes before you can know whether the probe’s landing was successful or failed.
In the painful process of waiting in the successful completion of a series of actions required, including the use of a parachute slowing, lit a rocket ready for landing, and stopped at the crater it carefully so as not to generate such as dust clouds.
Engineer lifulini said: “even if one of the things that has done just right, it will come to an end. ”
All the preparatory work and scientific equipment there may be a long wait in exchange for “one chess mistakes full set all bets are off”, this inevitably makes people feel horror.
Suspense surrounding events attracted wide public attention, video viewing on the network has more than 36,000, is constantly increasing.
However one of the head of the California Academy of Sciences Morrison Planetarium Cook is confident, he said, “has so many things can go awry, but NASA engineers are not likely not taken into account. They got used to accomplish the impossible tasks, so that night I will pray in silence, in front of the computer waiting for the results, hope will be a perfect ending. ”
“Curiosity” corresponding things, Rover cars, weighing 900 kg, provide impetus to nuclear fuel, plutonium, carry a range of advanced scientific instruments, in November last year from the United States, Florida, launched, mainly for exploration of Mars in the past or present existence of environments suitable for life. The project with a total investment of us $ 2.5 billion, is by far the most expensive of the Mars exploration project.
