A mole pulling on the red plant | TIME ONLINE


What does Mars look like inside? How big is the planet's core? How is he? To date, m & # 39; no answers to these questions. The probe Insight, conducted by the agency & # 39; the Nasa space & # 39; USA, now has the task of providing new knowledge and, incidentally, violates record. Tonight at 20:54 German time, the device is to land on the Red Planet, remains & # 39; in & # 39; place and dig for months on the planet. B & # 39; this way, the researchers want to better understand how rocky planets formed in our solar system four & # 39; and a half billion years ago and why it developed so b & # 39; a different way.

If everything goes as planned. Concerns: In the history of international missions to Mars, more than one in two failed. The hope: Nobody knows better to land on the Red Planet by Americans. 20 German time clock transmit landing of Nasa here alive.

A "in a larger parking lot & # 39; Mars". At least this is how the authority describes the area & # 39; landing in Elysium Planitia plains southwest of the large volcanic complex complex. Which is surprising: M & # 39; there is absolutely nothing to see there – the & # 39; now, it was necessary to look at the special structures closely as possible. But there is little stones or rocks greater, no sloping and no sink, robot & # 39; & # 39 x descent, is likely to stop by & # 39; safe way. Insight is 550 kilometers from the landing spot of curiosity, about 2,600 kilometers from 8,400 kilometers from Spirit and Opportunity.

Not much going on, too much sun: Zone in Elysium Planitia plain is seen as a suitable place for landing. The blue and green regions in & # 39; this map are lying areas, high red and yellow terrain.

Since the beginning of & # 39; in January, one has to create the plan "the deepest, always b & # 39 technique, man, hole on another celestial body", said in a press of the Aerospace Center Press German (DLR). Means: you want to dig up to five meters deep. The significant responsibility for record drilling should be HP3, which was developed by the DLR employees The pack Heat Flow and Physicality, Because of his skills also affectionately called "Mole".

Braking is at least until March 2019

The equalize device & # 39; hammer 50 centimeters into the rock, then stop by DLR. So it & # 39; be measured and monitored devices before in the top 50 centimeters deeper. The probe uses a fully automatic mechanism and the side face of facing & # 39; electricity and pulls a flat cable equipped with & # 39; measuring sensors behind in the Martian soil, also says. B & # 39; & # 39 collaboration with, others newly developed devices, will measure the internal temperature and use sismometru to record earthquakes, meteorite impacts and all other movements shake Mars.

The good old acquaintances help transfer the collected data to Earth. The Mars Reconnaissance Orbiter spacecraft Mars Odyssey and 2001 flying over the landing site twice daily and serve as relay stations, ie radio stations, for data traffic.

"Since we do not know what surprises – for example due to tougher rock – jistennewna underground, go b & # 39; great attention and plan to reach deep target in & # 39; number & # 39; weeks to March 2019, "said Tilman Spohn from the DLR Institute for Planetary Research in & # 39; Berlin message.

Because Insight is titgħawwex only, but also answer many scientific questions (how tall she Marskern, x & # 39; consist of, is liquid or solid, as is the crust thick, as is active Mars, how kill off the meteorites?), the mission has a total of & # 39; & # 39 two years; land. Billion dollars, equivalent to about 880 million euros, spent people responsible for the & # 39; now.
