"Mole of Mars" traveled as researchers call the InSight, traveling to 485 million kilometers to reach the red planet on Monday. He will have a mission toInvestigate Martian interior; to investigate the composition of the soil and the processes that develop under its face. It will also measure the temperature and capacity of the planet's inner tier.
Tilman Spohn, the scientific director of the experiment, explains that "every planet in a thermal machine is in principle, the residual heat generated by that type of machine is a measure of the work carried out by the engine, we measure that residual heat and develop accounting models for forming the planet. "
Studying Mars would help to better understand our planet.
InSight will be land in the area Elysium Planitia, to the north of Martian boats. The region is quite flat and free of stone and large stones. Marsh trails have not yet studied that part of the planet from the surface. The nearest device is to roll NASA "Ashamed" and it is about 500 kilometers away. Unlike "Wonder", the InSight will not move, but will stay in the wharf.
As soon as the module is secured, the search for a "mole" option will start. A robotic arm that carries "InSight" will pick up the HP3 up there. "In the landing site with (between three and seven meters) free material on the ground," said Matthias Grott of the DLR. It's important, because HP3 has designed to eradicate sand. "If we find a big stone and we can not continue, it's over," it warns.
In fact, HP3 does not have the appearance of a pig only from a small rocket: a 40 cent long dial that ends in a point. It will dig in 50-centimeter parts to a depth of five meters. For this he has an electronic and automatic hammer mechanism. The device has the InSight wires so that scientists can measure the flow of underground heat. If everything goes well, it will send data to the Earth for two years.
Another device will also be used, a seismograph that will measure earthquakes and possible earthquakes on Mars. In the Moon and measurements of this type have been made for years but Mars has yet to achieve it.
For Spohn and for colleagues, this mission is important to draw conclusions about our own planet. "As the inhabitants of the Earth, we have seen how special this is when we have investigated other blanets," he said. "Science is a good part of comparison."
The InSight mission, which has costed some 650 million euros, it should have really started in 2016. But due to problems with one of the instruments, the withdrawal had to be delayed for two years. The design of the 360 kilogram module has mainly based on Phoenix spacecraft, which led to Mars in 2008.
Today he arrives at Mars after a six-month trip through space.
Here is the first module of US space agencies on Mars since Craffdeb in 2012 and researchers are nervous. According to NASA, only 40 per cent of all the trips launched in the Red Planet world are successful. The European Space Agency (ESA) suffered an example of how difficult it is to go on the neighboring planet in 2016: Schiaparelli scored an accident during the computer-based approach to a computer failure. This Monday, NASS will not be the only one who will follow InSigh landing, "because it will be broadcast live for everyone.
Although he has not settled again on the Martian soil, the robot is already in succession. In 2020 the rover Mars 2020 will begin, a kind of better version of Curiosity.
