The United States space agency Nasa has landed a new robot on Mars after a seven minute dramatic attack to the surface of the Red Planet.

The InSight auditor's objective is to study the deep interior of the world, and to make it the only planet – apart from Earth – examined in this way.

There was a confirmation of touchdown at the queue at 19:53 GMT.

Anxious amount came to an end when the robot is home to a series of updates on its fall.

Nasa's mission management at the California Jet Propulsion Laboratory (JPL) triggered when InSight became apparently safe on the ground.

The agency's chief administrator, James Bridenstine, celebrated the so-called "incredible day". President Trump congratulated him to offer his congratulations, he told reporters. JPL director Mike Watkins said that the success should remind everyone that "doing science must be bold and we must be auditors."

InSight now sits on an extensive level field, Elysium Planitia, close to Red Planet's media. Before landing, Nasa was called the largest car park on the Mars ".

The first picture of this landscape came back very quickly, within minutes. He showed a rough scene, fishing of the circumstances of the robot.

The image was taken through the transparent lens cap of a camera that has located at the bottom of the banks. The dust that started in the fall hid much of the scene, but it was still possible to make a small rock, one of the viewer's feet and the sky on the horizon.

Better pictures will be taken in the next few days.

Like all previous attempts to land Mars, race Insight to the surface – the first attempt since 2012 – was a time-related relationship.

Step by step and meter per meter, the robot reported its progress.

He had gone to the atmosphere faster than bullet high speed, using the combination of heat heat, parachute and rockets to bring it to lightly stop.

The key to the ongoing survival of InSight now on the strict face of Mars is to use its solar panels, which are reserved for the fall.

The robot must start to generate power to operate its systems and to heat up sub-zero temperatures that continue on the Red Planet.

Only when these concerns are taken carefully can Nasa start thinking of an InSight scientific mission.

InSight: Mission of the heart of Mars

One of the major achievements in the InSight mission to date has been the role that has emerged from the two small broadband libraries sent to Mars along with the robot lander.

Here are the small spacecraft, of the name MarCO A and B, which transferred the applicant's signals back to the Earth during the rotation to the surface. They both cost less than $ 20m and their technologies are now sure to be much more prominent on future inter-volcanic journeys.

And as if they were highlighting their abilities, the small satellites also made a picture of Mars.

"With all the data returned by InSight during its exciting, collapse and landing (EDL) successfully – what you will see before you get an image taken around 4,700 miles from March, about 10 -15 minutes after EDL itself, "MarCO explained the main engineer Andy Klesh.

What's different about the InSight mission?

This will be the first scanner to present his investigations to understand inside Mars. Scientists want to know how the world has built – from its core to a movie. InSight has three experimental experiences to achieve this goal.

The first is a package of Franco-British seismometers that will be raised on the surface to listen to "Marsquakes". These vibrations will reveal where rock layers are and what they are doing.

A German-led "mole" system will grow up to 5m to the floor to take the temperature of the planet. This will give a sense of how active Mars is.

And the third experiment will use radio transmissions to determine accurately how the planet looks at its axis. Proxy project scientist, Suzanne Smrekar, uses this phrase: "If you take raw eggs and eggs that have cooked and you will turn them out, they are squeezed & Differently because of a liquid distribution in the interior. And today, we do not know properly if the core Mars is fluid or firm, and how big that core is .InSight give us this information. "

Why do we need to know this?

Scientists understand very well how the interior of the Earth has structured, and have some good models to describe the beginning of this architecture at the birth of the Solar System more than 4.5 billion years ago. But the Earth is one data point and Mars will give researchers a different perspective on how rocky planets can be embodied and evolved over time.

InSight's chief scientist, Bruce Banerdt, said: "The little details on how planets evolve and what we think make the difference between space like the Earth where you can go on vacation and get there, and place like Vine where you'll burn in seconds or places like Mars where you'll freeze to death.
