According to NASA, this instrument will allow scientists to understand the internal structure of Mars, having studied the fluctuations of soil
Automatic interplanetary station Mars InSight first established on Mars seismic sensor. This was reported on its website, the National Directorate of the USA on Aeronautics and space research (NASA), noting that this is the first such device mounted on the surface of another planet,reports TASS.
“Station InSight placed the first device on the surface of Mars, thus fulfilling one of the main tasks of his mission, – noted in management. – Obtained new images show that the seismometer on the ground”.
According to NASA, this instrument – Seismic Experiment for Interior Structure (SEIS) will allow scientists to understand the internal structure of Mars, studied the ground vibration or the so-called marsotryaseniya. Analyzing the way seismic waves travel through the shell of Mars, researchers hope to determine the depth and composition of each layer.
“Using the seismometer on the surface is how to attach the phone to your ear, – said a leading designer SEIS Philip Lognonne from the Paris Institute of Earth physics and University Paris VII them. Diderot. – We are thrilled that we have the ability to “listen” to seismic waves from the surface of Mars, and out of his depth”.
Device that measures marsotryaseniya was produced by the French National centre for space studies (CNES), with the support of several international scientific centers. In the coming days, the InSight team will work to calibrate the seismometer that is placed on the surface of the red planet with an inclination of a few degrees. The first measurement, you will be able to make and transmit to the Ground only after installation in the correct position.
“The schedule of the planned activities of the mission performed even better than we hoped, – said the head of the Mars InSight project Tom Hoffman. – Successful placement of a seismometer on the surface is a wonderful gift for Christmas.”
The wind on Mars
1 Dec station for the first time could record and send to Earth the noise of the wind on Mars. The atmospheric pressure sensor and the seismograph recorded the noises caused by the vibrations, which “created the wind over solar panels” station. Its speed ranged from 5 m/s to 7 m/s, blew from the North-West to South-East.
NASA has posted a record and advise everyone to use headphones or even a sub-woofer (speakers that reproduce low frequency sounds) to better hear the sounds.
