NASA robot "Insight" ready to land on Mars



[ad_1]

Washington, Berlin, Graz – A look at the structure of & # 39; inside Mars must get the NASA mission "Insight". The provincial probe should be set up on Monday night on the red plant and take their task in the coming months as a geophysical observatory. The Graz Institute for Space Research (IMF) of & # 39; of the Austrian Academy of Sciences is involved in the evaluation data.

The probe NASA mission "Insight" (Internal Exploration using & # 39; Seismic Investigations, Geodesy and Transportation & # 39; Heat) want to go to the bottom of the planet. If everything goes well, the landing, which was launched in & # 39; May, will land in the Elysium Planitia region at the equator north & # 39; Mars around 9 pm after a journey & # 39; about 485 million kilometers. For two years he will perform geophysical investigations on the structure of & # 39; inside & # 39; Mars. The researchers hope to draw conclusions about the early history of the red planet and ultimately the formation of the world more than four & # 39; billion years ago.

On board are scientific instruments that researchers use to study the interior of & # 39; Mars. The latest 2012 Nasa has b & # 39; car success "Curiosity" f & # 39; Mars. The landing on the red planet is considered extremely difficult – only about 40 percent of missions around the world launched earlier in & # 39; March were successful according to NASA.

The building should be explored planet

"Insight" weighs 360 kilograms and completed the journey & # 39; seven & # 39; his month in neighboring planet Earth by 10,000 kilometers per hour. After entering the Martian atmosphere, the item is going to fly with the help of & # 39; braking parachute and missiles. Researchers control the robot from & # 39; control center in & # 39; Pansadena, California.

By & # 39; & # 39 combination; specialized instruments, Insight can & # 39; hear & # 39; deep below the surface & # 39; Mars. Among other things, the pulse rate (seismic), the "fever curve" (planetary heat flow) and reflections (rotational variations) of the planet are examined, as described by the Institute Günther Kargl for Space Research ÖAW. The Austrian researchers are also involved in the mission: the IMF in & # 39; Graz is responsible for evaluating & # 39; part of the scientific data collected during the mission.

First, the check-out the "Flow Heat and Pack & # 39; Physical Properties' (HP3) must be done & # 39; special device that resembles nails with & # 39; Martel built. With its help immerse in the Martian soil. After, f & # 39; December, it will be really interesting to IMF experts: will draw conclusions about the mechanical properties of the soil of the Martian surface on the basis of measurement data recorded on the device enter.

"We meet at least three meters & # 39; land, the deep target would & # 39; five meters", said Kargl to APA. To reach this depth, required 10,000 hit. It will take about two months, "he said. The IMF contribution consists in investigating the mechanical properties of soils, which can be obtained from the behavior of penetration HP3 mole in the Martian soil. The participation IWF has also been supported technically by the Soil Institute of Mechanics and Engineering Foundation of the University of Technology & # 39; Graz and financed by the Austrian Agency for Research Promotion FFG.

In addition, facial manipulations with blade deployment instrument branch are also made to be able to determine more mechanical soil parameters regolith b & # 39; an independent investigation, as called for by the IMF.

After the sign of & # 39; landing "I made it" sent

Currently, Mars is about 146 million kilometers from Earth, the radio signals require about eight minutes to reach the earth stations. "At Insight", sent two small satellites for the first time, flying after a provincial probe and, so to speak, observe the immersion & # 39; "Insight" into the atmosphere and following the landing sequence the first row, without a leg ". as the landing landed safely on the ground, it sends the signal" I made it ".

Since the provincial probe can not communicate directly with the world, existing space probes orbit to jump as relay stations. Due to the geometry of their web, however, can & # 39; there is a delay in the transfer. At the time of landing, the space probes "Renaissance Mars" and "2001 Mars orbiter" are expected to be used.
