Mars Mole Insight is the exploration of a Japanese soil for NASA


BerlinA Mole for the Japanese soil: When NASA Insight Robot landscapes on Mars's surface as planned next Monday (November 26), the work starts on HP3. The tool, developed by the German Aerospace Center (DLR), is to dig itself as a pig to the ground to be inherent secrets of the Red Planet.

HP3 – known as Marsmaulwurf is kind from its developers – including hammer, mechanical wells and electric motor. "The mission is to explore inside Mars," explained Tilman Spohn of DLR, who is leading the HP3 experiment scientifically.

It's about learning more about the planet's structure and the dynamics beneath its face. The marble fund will help by measuring the temperature and productivity of the soil, says Spohn.

So, Insight is to find Mars secrets

But before that, Mars Mole has to survive the landing on the planet. How trivial this final phase of a trip to Mars, the European Space Agency That has proved in 2016: Your Mars Schiaparelli search declined as a result of a computer error when landing. Missing missions – like many other people:: Just about 40 per cent of all Mars trips launched so far have been successful.

At around 21,000 km / h, Insight will enter the Martian atmosphere on Monday. The waterfront shield must resist a temperature of 1500 degrees. Thirteen kilometers above the surface, then a parachute reveals, which is meant to reorganize the auditor so far so that it can be stolen from the end more or less lightly to ground through its brake pads.

Hell travels with uncertain consequences

Hell is a journey with an uncertain result – it is nerve equivalent and those responsible in advance. They can no longer influence this sensitive period of the mission. All the orders required for the complex processes are programmed to the land and run automatically. Interventions of the control center on the ground are no longer possible – because the signs of a large distance of the land would arrive after a quarter hour on the banks. In the worst case, Insight is then a space junk on Martian broadleaved soil.

If the landing succeeds, the landowner will land in Elysium Planitia to the north of Mars mediator. A region that is mostly flat and free of rocks and larger rocks and has not yet been explored by previous Mars trips. The curiosity of Nasa Rover is still based at a distance of 500 kilometers – and so it's still all Mars instruments closest to the landing site. Unlike it, however, Insight will not move, but it will remain on the landing site.

Once the landowner is safe, the search for a suitable location for Marsh Marsh starts in the surrounding area. A robotic arm attached to Insight will charge HP3 there.

"On the landing site, we expect three to seven meters of loose material in the ground," said Matthias Grott of DLR. This was important because HP3 had planned to displace sand. "If we hit a big stone and get stuck, it's over."

Five meters deep in the Mediterranean soil

Externally, Mole Mars is not reminiscent of its animal names, but instead of a mini rocket: a 40-centimeter rod that taps in the front. In increments of 50 centimeters each it must penetrate to a depth of five meters. A fully automated and electric drive hammer mechanism makes this possible.

With Insight, HP3 has been connected by a cable so that researchers can measure the heat flow in the ground permanently. If everything goes well, the fund should send data to the Earth for two years.

In addition to HP3, another tool will be used on Mars – and German researchers have also worked on it. The DLR and the Max Planck Foundation for Solar Systems Research in Gottingen were involved in the development of a seismometer.

It should measure the soil vibrations and possible Marsquakes. Although a long-term series of measurements could already be held on the Moon, this has not yet been achieved on Mars.

Spohn and colleagues consider the mission important because it allows us to draw conclusions about our own planet. "There's a lot of science in comparison," said Spohn. Therefore, by exploring the geophysical processes of the desert planet, the earth's development can be better understood.

In fact, the tour of around 650 million euros had actually begun in 2016. However, due to a drop-off research tool, the start must have to be deferred by two years. The 360 ​​kilogram Lander design has basically based on the Phoenix space advisor, which led to Mars in 2008 and triggered data for several months.

Insight's successor is already in the starting blocks: In 2020, the "Mars 2020" will be launched, a type of revised version of "Curiosity".
