"It was so intense, you could feel the emotions"


For about a whole year "InSight" was on the road, now the NASA robot landed on Mars. A device on board should provide initiatives in its interior. It comes from Germany.

The first mill in space was made of plush. When the space shuttle "Endeavor" for its last flight dropped in 2011, Astronaut Andrew Feustel was given the "small mole" of Czech signature Zdenek Miler in his luggage. More than seven years later, another mole made it in space. This time it consists of a hammer, mechanical springs and an electric motor. The device came on Monday on Mars – and is there to run as soon as possible in the interior of the planet.

The "Mars Mole," or the researchers called her name, is the official name HP3 ("Heat Flow and Physical Properties Package"). The research instrument was developed by the German Aerospace Center (DLR). The HP3 is still on board in InSight (inter-fleeting exploration of seismic surveys, geodetic and half-transport), which sends the US space Nasa to Mars to a 485 million kilometers journey in May. On Monday, "InSight" was successful on the Red Planet.

"A wonderful day"

It was the first Mars landing of Nasa since Curiosity & # 39; 2012 – an exceptionally difficult maneuver. Only 40 percent of all earlier Mars launch missions worldwide were successful in NASA. The scientists responded thus like InSight & # 39; achieved his goal. "What a wonderful day for NASA," said American space service Jim Bridenstine, who was in the control center. "It was so intense that you could feel the emotions." Only seconds after launching, US Vice-President Mike Pence had telephoned him.

"The whole mission wants to discover the interior of Mars," declares Tilman Spohn of DLR, which teaches the HP3 experiment scientifically. It is about learning more about the structure of planet and the dynamics of its surface. The marmolol will help with measuring the temperatures and the leverage of the bottom. "Every planet is mainly a hotmelt engine, and the drainage of such a machine is a measure of what the engine is doing in that – we measure waste water and make use of models of formulation. "

Site for Mars mole

Landed is "InSight" in the plane Elysium Planitia north of & nbsp; the Marsjers Equator. It is a region that is largely flat and free from larger stones and stones. Previous Mars missions have not yet investigated this area. The still active NASA rover "Curiosity" is at a distance of 500 kilometers – and is therefore the closest. Unlike him, however, "InSight" will not move but remains at the location.

Even though all of the system's landings are discussed, the search for a suitable location for the mole mole in & quot; begins; the direct environment. In a robot connected to "InSight", HP3 will get there. "At the location we have three to seven meters of loose material in the ground," says Matthias Grott of DLR. This was important for HP3 development for seven development. "If we get a great stone and stand, then it's over."

Data of Earth

Apart from the marshal design, not a few of her puppies, but rather a mini-rocket: a 40-centimeter long stick, which is the foreground. In return of 50 centimeters, each he has to penetrate into five meters deep. An electric drive, full automatic hammer mill makes it possible. With "InSight", HP3 is connected to a cable, so the researchers can measure the heater in the underground. If everything goes well, the mole must send data to the Earth for two years.

In addition to HP3, another instrument will be launched on Mars – and German researchers have also worked on the work. The DLR and the Max Planck Institute for Solar System Research in Göttingen were involved in the development of a seismometer. It must measure grounds and possibly Marsjers. Although long-term series of measurements can already be executed on a month, this has not yet reached Mars.

Geophysical processes of a desert funnel

Spohn and his colleagues consider the mission important because it can make our conclusions about our own planet. "When earthquakes, through the other planets, we have speculated how special the earth is," says Spohn. "Science is a good deal of comparison." Thus, through the geophysical processes of Mars' desert deserts, the development of & quot; the earth will be better understood.

The estimated 650 million dollars "InSight" mission started in 2016. Due to a reliable research instrument, the launch was replaced by two years. The design of 360-kilogram Lander is based on the spacecraft "Phoenix", which has landed on Mars in 2008 and has included several months.

The location and the reactions you follow can follow:

A sequel to "InSight" is already in the beginning blocks: In 2020, the rover "Mars 2020" has been set up, a kind of new version of "Curiosity".
