Mars: Nasa Earthed InSight Robot to Inspect Interior of Planet

InSight quickly returns first image from Elysium Planitia

The US space agency Nasa bought a new robot in Mars after a seven-minute dramatic fall on the surface of the Red Planet.

The InSight probe seeks to examine the deep interior of the world and to turn it into a single planet outside the world examined in this way.

The confirmation was received at 19:53 GMT.

He ended an anxious wait for the robot to compensate for a series of updates on which he landed.

NASA's mission in the Jet Propulsion Laboratory in California (JPL) was clear when InSight was safe.

James Bridenstine, chief executive of the agency, congratulated what he called "a magnificent day". President Trump told reporters that he began to offer congratulations. And Mike Watkins, director of JPL, said success should remind everyone "we have to be brave to do science, and we have to be an explorer."

InSight now sits on a vast plain plain known as Elysium Planitia, close to the equator of Red Planet. Before the landing, Nasa called it "the largest parking spot in Mars".

The first picture of this view came back in minutes in very short time. The robot spotted the environment, the fish eye showed the view.

The image is taken from the semi-transparent lens cap of a camera placed at the bottom of the vehicle. The dust accumulated on the top of the stage concealed most of the scene, but it was still possible to remove a small rock, one of the legs of the probe and the sky on the horizon.

Better photos will be taken in the coming days.

The race against Insight's surface – like all attempts at landing on Mars – was the first attempt – a tense relationship since 2012.

At the stage of the stage and up to a meter of meters, the robot returned the progression.

He entered the atmosphere into a soft stop, faster than a high-speed bullet, with a combination of heat shield, parachute, and rockets.

The key to InSight's continued survival on Mars' hard surface is the distribution of stacked solar panels for landing.

The robot should definitely start to operate its systems and generate power to heat the equipment at temperatures below zero on the Red Planet.

Just considering these sudden concerns, Nasa can begin to think about the scientific mission of InSight.

InSight: Quest, the heart of Mars

One of the major achievements of the InSight mission so far has been the role of satellites in the size of two briefcases sent to Mars along with the robot lander.

It was this mini spacecraft called Marco A and B, which transmitted the signals of the probe back to Earth when plunging into its surface. The pair costs less than $ 20 million, and it's clear that these technologies are much more prominent in future interplanetary missions.

And as if to highlight his talents, the small satellites photographed Mars.

"After seeing all the data back successfully during InSight's exciting entry, descent and descent (EDL) sequence, we've got about 4 thousand 700 miles from Mars, about 10-15 minutes after the EDL." is an image taken, "explained Marco chief engineer Andy Klesh.

What is different from the InSight task?

This will be the first probe dedicated to investigating the interior space of Mars. Scientists want to know how the world was built – from its core to its shell. InSight has three main attempts to achieve this goal.

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

A German-led "mole" system will nest up to 5 m above ground to get the planet's warmth. This will give you an idea of ​​how active Mars is.

And the third experiment will use radio transmissions to precisely determine how the wave on the axis of the planet is mocked. Suzanne Smrekar, an assistant project scientist, uses this analogy:, If you take a raw egg and a cooked egg and rotate them, they shake differently due to the distribution of the inner liquid. Mars is liquid or solid and how big is the nucleus. InSight will give us this information. "

Why should we know that?

Scientists understand very well how the internal structure of the Earth is structured and have some good models that define the beginning of this system up to 4.5 billion years before the birth of the Solar System. However, the Earth is a data point and Mars will give researchers a different perspective on how a rocky planet can evolve and evolve over time.

InSight chief scientist Bruce Banerdt said: "The little details in the evolution of planets are what we create the difference between a place like the Earth where you can go on vacation and tan, and a place like Venus where you will burn in seconds.
