For Sunday, all eyes will be back on Mars

Only a few bodies in our solar system could be scientists
pre-seismological measurements; long-term series of measurements are available –
next to the earth – so far only from the Moon. And Mars? Like 1975 with Viking 1

Seismometers have also become scientific instruments.
However, the meters did not have direct contact with the ground, but they were rigid
connected with landing units. Therefore, the data is primarily data

"Meaningful seismological measurements are still on Mars
"says Ulrich Christensen, director of the Mak Planck Institute, fr
Exploration of solar systems and team member team seismometer InSight,
SEIS Instrument (Seismic Experiment for Internal Structure) by InSight

The instrument, developed under the guidance of France's space agency CNES
and was piggibacked on the platform's platform platform for landing.
However, after landing, the InSight robot arm needs to mount the measuring device to
Put the ground. The type of hood, which is covered in the second step,
serves as protection of wind and temperature.

Researchers are assuming that the Marcuses appear less and more
worse than their earthly colleagues. The reason might be
Finally, the most modern layer of Mars has long since separated from him
The tectonic plates existed. However, first of all, the movements on Earth are what solves them
at the border of the board shake. Mak Planck researchers hope for SEIS
not only knowledge of the current geological activity of Mars.

Seismological measurements also provide an opportunity to learn more about
the inner shell structure and the composition of the planet for experience.
Considering that seismic waves do not spread to the surface of the planet
but also through his interior. At the boundaries between
they are rejected and reflected by different layers. When and where
The wave then comes to the surface telling us what the conditions are
found inside, "explains Christensen.

First of all, it is interesting to what extent are the "inner values" of Mars
different from those on Earth. Is it made of other materials? How accurate they are
to get the layers? And is it – like in the case of the Earth – liquid?
Iron core? "We want to understand how Mars has changed from its origin
developed – and why it is so clean of today
makes a difference, "says Christensen.

Unlike many seismometers, earthquakes on earth usually
shot in the composite, Mars seismometer is a unique fighter. "SEIS can

explains Marco Biervirth, project manager SEIS at Mak Planck fr
Solar research system. "To compensate for this deficiency, they are required

the other is that the instrument is exactly horizontal on an uneven and stony state

Another measuring instrument InSight is HP3 (Heat Flov and
