After a six-month tour of the world, InSight Mars will be on the NASA mainland, climbing through the space at 12,300 meters, and # 39; going into the tight martian atmosphere of Monday to start a six-to-half-minute rupture to the surface, breaking a billion dollar mission to examine the hidden inside of its & red planet.

"InSight does not have less than a better understanding of the birth of the Earth, the birth of our planet we are going to do, and we will do it by & # 39; go to Mars, "said Principle Investigator Bruce Banerdt.

On Earth, plate tectonics and mantle have always changed into the deepness of their planet, and # 39; including its history and its development. But Mars is a smaller planet and much more active than Earth, which preserves "fingerprints" of the foregoing processes.

"By mapping these boundaries, the different different sections of the interior of the planet, we can then develop a better understanding of how the planet was created and how Our planet has come as it can be where we can live and play and have a good time for the West … So we'll go to Mars. "

Final correction planning was planned on Sunday afternoon to influence InSight; attack and ensure that it would land on a wide range called Elysium Planitia.

But as it comes to Mars, a total of InSight climbing 90 million miles will be far beyond direct management – or help – from Earth engineers. In fact, it will take 8.1 minute radio signals to make the route to the Jet Devulsion Laboratory in Pasadena, California, where scientists and engineers are concerned to wait to find out if the boat- space is successfully done to surface.

"We did everything we do, we did everything we can think to make sure we're successful," said Tom Hoffman, the InSight project manager. "But you do not know what's going to happen."

Inside the inside of a "rubbish" flying wing and protected by a heat shield, InSight starts around 1947 GMT on Monday, and # 39; Trying to make a sustainable trout up to 7.4 times the Earth's Earth's strength while it is fast to slow down and down; Heated up to about 2,700 Fahrenheit degrees.

Four minutes later, at a height of 7.5 miles and now moving at 928 meters high loud, there will be a 39-foot parachute; solved, sold by 15,000 pounds per square degree to move their craft to 295 mph or so.

The useless heat shield is now removed, showing the bottom of the stream to the environment, and 10 seconds later, it displays its three trips and locks it.

Two seconds later, about one minute before it takes away, an InSight look-up radar will be applied, a higher volume and a level of specialization vessel and a & # 39; Feeding that data to the land flying computer.

Finally, less than a thousand above the surface and discharge at about 134 meters, InSight will be discharged from its & # 39; console and a parasite will drop free of charge by itself.

One second after that, twelve rows will be fired up, each generating about 68 pounds of length and length; as they hit 10 times in the second place, and # 39; move to spacewash to one side so that they can. Falling the plenty and fall.

By generating the speed of the horizontal and its. slowing to about 5 miles, it is expected that InSight will drop on Elysium Planitia on 1954 GMT, about 2 p.m. a local time on Mars.

At least five minutes later, after waiting for the dust to put the thrush up to the ground, two InSight world sun divisions will appear to begin the recycling of batteries the sea. The drawings attracted around 1,300 watts of Earth power, but at Mars, with a very dusty atmosphere, they direct only 300 to 600 or so.

The induction, sequencing and experimenting series was measured simultaneously with the NASA Orbiter NASA destination, which is scheduled to record the UHF telemetry on radio from Insight when it goes to the surface. That data will be stored on board the orbiter and will be returned to the Earth about three hours after replacing.

Returning data from two probation spaces called Mars Cube One – MarCO – A and B launched by InSight will be back back in May. They are the first "CubeSats" called an interplanetary voyage and are the main flying controllers who can follow InSight.

Unlike the much more advanced Orbiter Report Mars, the Marco spacecraft, which costs around $ 18.5 million for the construction, a radio device that can be given in UHF signals from InSight and taking them Back to Earth often at band X-races.

"If it works, the two Marco spaceships will add the data for InSight access, output and output almost as it happens, which will be very cool for the MarCO team and the InSight team have to prove what is going on with the landlord as quickly as possible, "said Anna Marinan, manager of the Mars Cube One project at JPL .

However, InSight – a & # 39; Stand for the search within the use of Seismic Studies, Geodesy and Heat Transport – a & # 39; adding "tone" with a computer back to Earth seven minutes after a contribution to identify its overall health.

But detailed telemetry does not fit until the Orbiter Mars Reconnaissance yields data that is stored three hours after its output; circulated. Confirmation of the sunshine exercises that are commonly used will be given back by the orbit of Mars Odyssey about five and a half hours after landing.

"I'm all very curious and extremely stupid at the same time, as everything we have done so far makes us feel comfortable and we'll be able to # 39; landing on Mars, "said Hoffman. "But everything has to go really. Mars may always throw us a bend."

But if it works, InSight pays with its first detailed overview of inside Mars, and # 39; Providing long-term answers to questions about how the planets collected when the solar system was associated with a cloud of debris for 4.5 billion years ago.

InSight is equipped with two main instruments: the Seismic Experiment Within Structure – SEIS – seismometer, provided by French space organization, CNES, and Heat Stream and Corporate View – HP3 – provided by Aerospace Group Agency, DLR. Both instruments cost European spouses of around $ 180 million.

To work correctly, both instruments must be depressed to Mars surface with a robot and both need a limited range of raids, a rock near the base of the man. The Elysium Planitia website has been selected as it just gives it.

"As insurgent engineers, we are really enjoying this site," said Rob Grover, an InSight, landing and landing intake manager on Elysium Planitia . "It's flat, there are not many rocks, it's a very safe place for land."

External cameras engineers will use to explore the location around their spacecraft to make sure that the tools are placed in the best place.

But it will not be fast.

"It's a kind of movable courage, slow motion compared to many of our previous things," said Banerdt. "It will take us two or three months, at least, to reduce our instruments. We need to check the area in front of our spaceship, make sure we do not add the instruments down on a rock or in a hole or something like that.

"And then we are very, very careful about how we put the instruments down … So it's going to take us a month or two that we can reduce the seismometer and Another month to heat down the heat and go down to the surface. We may look early in the spring when we are going to start "Bring back that kind of science from Mars."

The seismometer is capable of detecting motions less than the scope of a haemomer, to the wild quakes of remote marsquakes, meteor strikes and even the marine floods caused by two small winter trips, Phobos and Deimos , mapped inside the structure of the planet.

The probe gives an uneven heat to its depth to a depth of up to 15 feet to measure the temperature of changes and, by generating out, make sure what heat it is; flow out of deep depth below.

In third research, a detailed analysis of radio signals from within Mars will provide a chance for scientists to be able to; Determine what the direction of a polar bear has on how it is slow, no precesses, as a result of the basic broadcasting in the interior. From these numbers, they hope to maximize size, density and participation; heart.

The aim of scientists is to help understand how the solar planets of the solar system – Moody, Venus, Earth and Mars – have been created and how they have become a different world we see today.

"The hot season is enough to be melted," said Banerdt to reporters last week. "The surface of the sun is watering. Mars is very cold today, but it's a good place to land in Earth for a holiday. We would like to be aware of why one plan is going one way and another plan will go another way. These answers are in detail about the structure that is created very early in the history of the planet. "

On Earth, this structure has been "a type of climbing built, both with plates of teethonean and a striking knock," he said. "And so, the evidence has been removed from the earliest processes."

But on Mars, the Earth's size is flattened where there is no plate plate and rotary tectonics working, there is evidence of the early history of the planet still preserved in the inner interior.

"These processes do all this happen in the first ten million millions of years," said Banerdt. "We would like to be able to understand what has happened, and these objectives are in the structure of its plan that will be established in those early years."
