DLR Marsmaulwurf HP3 before landing with NASA InSight mission



DLR: November 19, 2018
For all Martians, do not forget next week …
It is said that this is the deepest deeper, that has got deep technology on another body, The HP3 (Heat Flow and Physical Property Package) developed and built at the German Aerospace Center (DLR) will penetrate the Mediterranean soil up to five meters below & the NASS mission InSight and measure the temperature and The thermal layer of the substrate there, This insight into the inside of Planed Red helps to better understand the formation and evolution of bodies like Earth. On November 26, 2018, at 20:53 European Central Time (CET), the landing has planned in the plain Elysium Planitia to the north of Mars mediator. At the same time, the voltage rises, where a precursory provincial search touches down within a 140 kilometer landing elipation and where the appropriate location can be found for the experiment Historic Mars on the landing site. So far, heat flu measurements have only been made so far on the Moon as part of the Apollo 17 mission, where the astronauter Eugene Cernan and Jack Schmitt spent hand drill by hand in depth up to three meters.

"Our Mars pig is doing well on board InSight on the last kilometers to Mars," said the scientific director of the HP3 experiment, Prof. Tilman Spohn of the DLR Foundation for Berlin-based Planetary Research. "The checks during the journey did not reveal any inconsistencies and now we are waiting time but confident that we will be in a few days."

Spohn and other DLR scientists will be land on November 26 at NASA Jet Propulsion Laboratory (JPL). Also on the site are employees of the DLR Cologne Consumer Center for space experiments, which are directly related to the Mole Management Order operations team. "By encouraging we're pulling, by selecting the induction point on the Martian surface to the complete penetration of a Japanese soil, we will work directly with US colleagues at the control center in Pasadena / California, "says HP3 operations manager, Christian Krause.

Currently the HP3 experiment restraint has been scheduled for January 2019. The Rammsonde will then work in small steps up to five meters deep. Marble sea hammers have a 50 centimeter sequence, these can be cut again and again by measurements and checks. The search uses a fully-powered and fully automatic hammer mechanism and draws a flat cable that has detection equipment behind it into the Martian soil. "As we do not know what unexpected – for example because of tighter rocks – we expect us underground, we are very careful and intend to reach the target depth in several weeks until March 2019", adds Spohn. In addition, as part of the HP3 experiment, an infrared radiometer, a called radiometer, which will become active soon after landing, will measure the temperature in the Martian surface of & # 39 ; r clean platform. In comparison, both data sets give the chance to end the heat flow of the planet.

Landing on "parking"

In order to reduce the risk of the mission, engineers and scientists have chosen a large volcanic complex of the Elysium south-east landing area, in the plain Elysium Planitia, which is mainly flat and stone-free and larger rocks. This deliberate monoton of the landing site by focusing on measurements in the Martian underground, means NASA researchers are now talking to a "seat" belt on many "parking". But even there, first of all, we need a detailed analysis of the land environment. Once this has been done, a robotic arm will establish the Seismic Experiment for Internal Structure (SEIS) first, where DLR is associated with science and has built in an international consortium under CNES French space agency guidance. The seismometer records Marsquakes waves and the effects of a meteorite that travels through the planet. This is followed by the abolition of Mars Mole HP3, developed and built in DLR. InSight's landing platform also hosts the American RISE experiment (Rotation and Inside Structure), which will record fluctuations in the Mars polar axis.

Moving beat at 1500 degrees Celsius

Before the measurements can start, InSight must survive the critical landing period about 7 minutes (EDL, Access, Drop and Land). At 20:47 CET on November 26, 2018, the search engine will penetrate the Mediterranean atmosphere at the bottom angle. The protective shield protects up to about 1500 degrees Celsius within three minutes. The friction with the Mediterranean atmosphere slows down the scanner until a parachute opens 12 kilometers above the ground, where the landowner grows on the surface of the planet. After its separation at 1200 meters height, InSight, which has been scanned by machines, sets forward. Contact the spacecraft during their flight to March and during mission operations NASA's Deep Space Network 70 meter antenna will be in California, Australia and Spain. The NASA Mars Recognition Orbiter and Mars Odyssey 2001 spacecraft flew over the InSight landing site twice a day and serves as exchanges for Earth traffic.

From March read the history of the earth

InSight is an unusual geophysical observation that has not existed in the solar history research history. The main scientific task is to investigate the planet and the structure of our adjoining planet. The mission is to investigate the development, structure and physical properties of the crust, the mantle and the core and draw conclusions for the formation and development of every body similar to the ground. Mars is a perfect destination, as it is easy to reach and a relatively ideal object to the ground.

The geophysical processes carried out after the formation of a metal core inside Mars and the rocky mantle were overwhelming and a fall slower faster than on Earth. In Mars, so, probably until today, fingerprints & # 39; the retention processes, which once formed the core, a mantle and a ridge in the planet similar to Earth. The researchers hope to better understand the evolution of the Earth to life development, even when compared to the vicinity of Mercury, Venus and Mars, as well as looking at the rock planets on other stars. The researchers are curious if they are – as in the interior – a hot, dirty core is still a Mars center and is it, unlike the Earth, even is totally melted, as some hypotheses suggest. "With this model," said Spohn, who developed this theory with American colleagues in the 1990's, "we could easily explain the absence of a magnetic field in the Mars today."

HP3 Tool on NASA InSight mission

The InSight mission is hosted by the Jet Propulsion Laboratory (JPL) of Pasadena, California, on behalf of NASA Science Directorate. InSight is a mission of the NASA Discovery Program. DLR contributed to the mission of the HP3 experiment (Heat Flow and Physical Property Package). The DLB Foundation is a scientific instruction, where the experiment was also developed in conjunction with the DLR institutions for space systems, optical sensor systems, space aviation and astronomy training, lightweight construction and similar adaptation, System dynamics and management engineering as well as robotics and mechatronics. In addition, industrial partners are taking part: Astronika and CBK Space Research Center, Magson and Sonaca as well as Astro- a Feinwerktechnik Adlershof GmbH. Scientific partners are the ÖAW Institute for Space Research and Kaiserslautern University. HP3 will be implemented by Center for Space Experiments (MUSC) in Cologne.
