NASA spacecraft designed to detonate & # 39; under the surface & # 39; Mars issued in the Red Planet on Monday after a journey of & # 39; six-month, 482 million kilometer and dangerous descent & # 39; six minutes through rose-hued atmosphere.
The flight controllers Laboratory Propulsion of Jet NASA f & # 39; Pasadena, California, felt from their seats and opened in screams, applause and props as the news arrived that the plant & # 39; of & # 39 Insight; three feet had touched on the red planet.
"No fault", stated chief engineer & # 39; JPL, Rob Manning.
"This is what we really ttamaq and imagined f & # 39; & # 39 in our minds; our minds", he said. "Sometimes things work in your favor."
Pair & # 39; small satellites emerged from Insight since their departure & # 39; May provided virtually updates in & # 39; real time of the supersonic descent of the spacecraft through the red skies. The satellite also handed portrait & # 39; fast surface & # 39; Mars.
The image was blurred with spaces & # 39; debris on the camera coverage. But that quick look at the vision showed a flat surface and ramliż b & # 39; a few grains – just what scientists had hoped. Images come much better in the hours and days ahead.
"What a relief," said Manning. "This is really fantastic." He added: "It never looks."
The Insight spacecraft reached the surface after going from 19,800 km / h to zero in & # 39; six minutes flat, using the & # 39; parachute brakes and engines to reduce speed. The radio signal confirming the landing took more than eight minutes to cross the nearly 160 million km between Mars and Earth.
It was the ninth NASA attempt to drop in & # 39; Mars since the Viking probes & # 39; 1976. All but one of the stages & # 39; the airline U.S. Earlier, successful.
NASA last landed on Mars in 2012 with Rover Curiosity.
Across America & # 39; America, were living in video & # 39; coins, planetary and libraries, as well as Times Square in New York.
"The landing on Mars is one of the most difficult jobs that people should do in planetary exploration," said left leading scientist & # 39; Insight, Bruce Banerdt. "This is a difficult thing, is something so dangerous that there is always a chance that something could quite inkomperabbli & # 39; go wrong."
Mars was the cemetery a large number of & # 39; space missions. S & # 39; now, the rate of & # 39; success in the red planet was only & # 39; 40 percent, and took a flight & # 39; orbital flight and landing of the United States, Russia and other countries since 1960.
However, the United States attracted seven & # 39; & # 39 Mars landing; success in & # 39; the last four & # 39; decades, without counting Insight, b & # 39; only one & # 39; touchdown.
No other country has been able to set up and operate spacecraft on the dusty red surface.
Insight was traveling to Elysium Planitia, plain near the Martian equator that hopes Insight hopes is so flat as a parking lot in & # 39; Kassachusetts with little, if any, rocks.
This expedition is the rock collection. Instead, the stationary artillery & # 39; 360 kilograms will use its robotic arm & # 39; 1.8 meters to place mechanical mole and sismometru on the ground.
The automatic hammering mole will crawl five meters & # 39; below to measure the internal heat of the planet, while listening seismometru & # 39; possible options.
But getting those instruments into force will take several months, because NASA scientists first have to assess the health of the spacecraft and the area of landing.
Nothing like this has been attempted before on Mars, Earth almost 160 million kilometers from Earth.
No Lander lasted more than several inches, and no sismom never worked on Mars.
By examining the interior of & # 39; Mars, scientists want to understand how the planets rock of our solar system formed 4.5 billion years ago and why it turned out so different – cold and dry Mars, Venus and Mercury burning hot , and Earth hospitable to life.
"We're trying to go back in time to the early stages of & # 39; outside the planet", said Banerdt. "The fingerprints & # 39; of & # 39; those early processes m & # 39; are only here on Earth."
However, Insight m & # 39; has no ability to detect life. This allowed in & # 39; hand future rovers. The mission & # 39; Mars NASA in 2020, for example, will eventually collect rocks brought back to Earth and analyzed for evidence & # 39; ancient life.
