A look at Mars InSight at Nasa to Mars! Science



After a seven-month, 300-mile mile, Nasa's Mars InSight's certification arrives at its destination and descends to the center of the center; red planet.

The laird came to rest on the dusty surface shortly before 8pm on Monday afternoon after a beautiful stretch that began when the spacecraft entered the Martian atmosphere at 12,300mph and finally finished minutes by The survey set on the ground, its quiet quiet South-

Confident scientists were welcome, arrested and arrested at the Nasa Jet Propulsion Laboratory in California when their home names are in place; come into the planet. "It was intense, you could feel the feelings," said Jim Bridenstine, administrator of Nasa. "What day for Nasa?"

The site in InSight, the Elysium Planitia, is one of the most polluting places in the foreign world: a wide range of flat lakes that the US space group says "the largest car park more on Mars ". But there is a landscape, of course, and hopefully quiet, just what is needed on InSight for its purpose of mapping within its plan.

"This is our first chance to look deep inside another planet, look at the structure and find out why it came to end as he did, "said Rain Irshad, head of the body's devolution systems at RAL Space in Oxfordshire, and one of a number of UK Experts in the InSight instrument.

The $ 814m (£ 633m) will draw on an instrument series to explore the shape and measurement of the planet's heart, grasp and crust. Due to that data, scientists hope to learn how Mars – and another rocky world – is created at the beginning of the 4.6bn solar system.

There is a danger to Mars screening, whether they should be & # 39; land, to leave or to; travel, only 40% of the campaigns. Nasa is the only spam that has been away from Mars. coming down, recently in 2012 when the rover Curiosity was circulated to the surface of "crane sky". In 2016, the European Spanish Party tried to try to put her own case on Mars, but Schiaparelli closed her back down the rockets too quickly and, fall into the ground.

You must have the InSight outside to & # 39; Play in an accurate way to safely connect. Shortly after he hit the tight atmosphere of Martians, he let down a parachute, and then he removed his heat shield and restored back-trusters to pull off his descendants. Confirms that InSight lasted what Naasa words were "the seven minutes of terror" and influencing the way back to Earth through the cube satellites to carry out the test to its destination.

InSight, which stands for Internal Investigation using Seismic Studies, Geodesy and Heat Transport, and & # 39; using three instruments to monitor Mars. A seismometer used by a mechanical device will be used as an ear to the ground and listening to an audio that will be made when rock subterranean stones passing each other on geological fault lines. These help waves will be avoided around their & # 39; planet and can show essential information about their structure.

Misleading scientists expect InSight that anything from a dozen to 100 Marsquakes will size 3.5 or more over a two-year mission against them. The seismometer is less likely to find vibrations less than a diameter.

"The most important question is the Mars that is seismically active," said Niall Bowles, a world scientist at Oxford University, who worked on the spacecraft. "We have indirect evidence for surface scratching, for example by looking at boulders falling down slopes in images from orbit, but & # 39; InSight is the first aim of putting a seismometer just on Mars's surface.

"The Marsquakes Assessment provides information on the structure within Mars and we hope to show more about how its planet has been created. Why is Mars smaller and lower density than Earth and Venus? ? It shows that the creation of Mars and the development was different in a different way from the Earth process or some of it in the early solar system that prevented Mars from to grow bigger. "

Another device, a heat circuit, will dig 5m to the ground and its; The extent to which heat rises through the planet. In the third test, scientists use the confidence of antennas outside to monitor their situation by making it so accurate that they can find out what Mars a & # 39; move on its database. The page size reflects the base size of its page; planet and whether it is flawed or hard.

The heart of the head of the earth is moving downward; Creating the magnetic range that has a life shield from harmful radiation, and its; Help you to stop the atmosphere with high energy fragments in the sunshine. Historically, Mars lost the magnetic range, and much of the atmosphere, causing the temperature of the fire and exposing the surface to rigorous radiation. InSight can explain how, Irshad said.

"Are there situations under the surface that could cause life to go down there to live?" She said. "If it disappeared under the surface, the future campaigns could be found in it."
