The probe InSight puts an important instrument on Mars



The first of & # 39; the first missions of & # 39; a mission has been set up.

Lots of readers' messages on November 26, 2018, in & # 39; e media or even in direct internet transport, to see the landing of the InSight probe on Mars. The problem is a cut-off of Interior Exploration with seismic surveys, surveys and transports.

Without a literary translation: The InSight probe, practically the first of those that landed on the Mars Flat, will investigate the interior of the planet fundamentally.

It is a NASA mission, or US, but with a broad involvement of European research institutions. International to one degree or another is actually a norm for all space probe. In this case, however, part of European scientists and technology is particularly marked.

The first middle

InSight has now realized an important milestone in preparing for large research program experiments. While global research, meteorology, as well as Mars's rotation and interior on radio signals that do not transmit it to earth, are practically from the public moment of landing.

The milestone is based on the successful location of SEIS (seismic experiment for interior structure) seismometer besides the problem. SEIS provided a special robotics search on a rare selected site at & nbsp; & nbsp; & nbsp; Premiere in the Irish astronautics.

Advantage of a distance

The seismometers already had the Viking 1 and 2 probes that landed on Mars in 1976 and worked there until 1980 or 1982. The position of these devices in the landing module itself was not proven. They were over-exploited by other problem systems.

As a result, another solution was chosen for InSight. SEIS and the second large-scale experiment, a Heat Flow and Physical Properties Probe Heat Detector (HP3) that reaches a record depth of 5 meters, are set next to the module. Close but far enough to keep the problem going.

Christmas party

In the case of SEIS, the site was found on December 19, 2018. The robot puts a seismometer directly in front of the module, at a distance of 1,636 meters. Be pleased at the spot as the best in terms of all criteria. Thomas Hoffman, NASA's InSight Project Chief: "Safe seismometer mounting was a wonderful Christmas celebration for us."

"The seismometer's position is as important as the InSight-facing self on Mars. The seismometer has the highest priority of any problem. We need to have our own function to meet three-quarters of our research goals, "Bruce Banerdt of the NASA Laboratory of Pasadena, Calif.

Seismic "Motorcycles"

The Seasonometer is to follow the motions in Mars cortex, "marsotrasenia". However, they work on a photographic flash that shines on the interior of the planet. From the transition of the seismic waves through the individual inner layers, the structure and composition of the layers can be dispensed with.

"To a seismometer right on the surface is a situation like your phone to honor your ear. We are set up to be in the best position to capture all the seismic wells of deep in Mars," said Philippe Lognonne. SEIS, scientific physicist at the Institute of Earth Sciences and Diderot University in Paris.

Great little focused

Despite all the efforts to place the seismometer on a flat spot, the device is called 2 to 3 arc-shaped steps. Fortunately, it can be fixed. The first data of the seismometer begins to begin after earth after its tuning. The full tuning of the device will take several weeks.

Above the seismometer, a wind and whole ship will also be installed to stabilize the environment around the sensor. The location of the HP3 Heat Detector on the surface will be completed for termination in January 2019. On the east side, on the same distance as a seismometer.

Currently, the first seismic data is expected to be expected. "We look for a singular candle when we get data from the InSight seismometer on Mars. I have a bottle for this occasion hidden," Bruce Banerdt said.

Next to American and French, participants in scientists and technicians from Germany, Switzerland, Great Britain, Poland and Spain are on an InSight mission. Specifically, SEIS supplied France. It is not known whether this country has given Bruce Banerdt a great vacation of juice hunting.
