Insight soon returned its first images from the Elysium Planitia

The agency & # 39; space & # 39; US NASA's new robot landed in & # 39; Mars after dramatic passed & # 39; seven & # 39; minutes on the surface of the Red Planet.

The Insight probe aims to study the interior deep in the world, and make it the only planet – aside from the World – examined by & # 39; this way.

Confirmation & # 39; touchdown came on a box 19: 53 GMT.

It ended anxious waiting which the radio series home robot & # 39; updates about his lineage.

The mission control & # 39; NASA in the Jet Propulsion Laboratory of & # 39; California (JPL) emerged in cheers when it became clear that Insight was safe on the ground.

The main administrator & # 39; agency, James Bridenstine, celebrated what they called "best day". President Trump was home to offer his advice, he told the journalists. And the director of JPL, Mike Watkins, said that success has reminds everyone that "to make science we should be bold and we should be explorers."

Insight is now a large, flat plain known as Elysium Planitia, near the equator of the Red Planet. Before landing, Nasa has been dubbed as "the largest park on Mars".

The first picture & # 39; this landscape came very quickly, within a few minutes. He showed a look of & # 39; the area of ​​& # 39; the robot.

The image was taken by the translucent lens cap & # 39; camera positioned on the side of & # 39; under & # 39; landing. The dust began in much discouraged descent from the scene, but it was still possible to make a small shelf, one of the probe feet and the sky on the horizon.

Best photos will be taken in the coming days.

Like any attempt & # 39; previous landing at & # 39; Mars, the race & # 39; Insight to the surface – the first attempt since 2012 – was tense affair.

Step by step and meter b & # 39; m, the robot reported back its progress.

It was entered by a bullet faster atmosphere b & # 39; high speed, using a combination of & # 39; escape & # 39; heat, parachute and rockets to bring itself to a gentle stop.

The key to the continued survival of & # 39; Insight now on the harsh surface & # 39; Mars is the deployment of its solar panels, which were stowed for descent.

The robot absolutely must begin generating power to operate its systems and heating equipment in & # 39; below zero temperatures persist on the Red Planet.

Only when these immediate concerns into account & # 39; & # 39 Nasa can; start thinking about the scientific mission & # 39; Insight.

Insight: core mission & # 39; Mars

One of the great achievements in the mission Insight & # 39; now was the role played two satellites & # 39; portfolio as sent to Mars along with & # 39; the ispiżer the robot.

Were these mini-spacecraft, called Marco A and B, which registered the probe signals back to Earth during the plunge feet. The duo cost less than $ 20m and their technologies are now sure to appear much more prominent interplanetarji on future missions.

And to underline their capabilities, the small satellite picture taken & # 39; Mars as well.

"After successfully bring all data back from Insight during the exciting sequence entry, descent and landing (EDL), what you see before you images taken roughly 4,700 miles from Mars, about 10-15 minutes after EDL itself "engineer Andy Klesh.

S & # 39; is different from Insight mission?

It will be the first probe to devote its investigations to understand the interior of & # 39; Mart. Scientists want to know how the world is – at its core to its crust. Insight has three main experiments to achieve this goal.

The first is a package of & # 39; sismometri Franco-British will be removed on the surface to listen "Marsquakes". These vibrations reveal where they are and where they made the rock layers.

System & # 39; mole run by German vacated to 5 m into the ground to take the temperature of the planet. This gives a sense of & # 39; as Mars is still active.

And third experiment uses radio transmissions to determine b & # 39; very accurate way the planet is similar on its axis. The deputy scientist project Suzanne Smrekar use this analogy: "If you take raw eggs and cooked eggs and you spinhom, they wobble b & # 39; a different way because the distribution of the liquid inside. And today we really do not know if the heart & # 39; Mars is liquid or solid, and how big that heart. Insight will provide us with this information. "

Why we should know it?

Scientists understand well how the interior of the Earth is structured, and have some good models to describe the beginning of & # 39; this architecture birth of the Solar System more than 4.5 billion years ago. But the World is one data point and Mars will give a different perspective on how researchers can rocky planet & # 39; fitting and evolve over time.

The chief scientist of & # 39; Insight Bruce Banerdt said: "The small details about how planets evolve are what we think make the difference between a place like Earth where you & # 39; to go on holiday and get a tan, like Venus and place where you'll burn in & # 39 seconds or a place like Mars where you'll freeze to death.
