Examined and listened to Mars. The first results of InSight


For the first time the person heard wind sounds on the Red planet. Record was "unplanned pleasure", speak in NASA. The interplanetary station NASA InSight in two weeks on Mars examined itself and vicinities and also wrote down the fluctuations generated by the Martian wind. InSight is in search of the place on the Red planet where it is possible to establish a seismograph and the tool for drilling of the five-meter well as the main task of the device is studying of a subsoil of Mars. The correspondent.net tells details. The first sounds of Mars on December 1 December InSight sensors wrote down "the low-frequency roar caused by wind gusts" which blew from the northwest on the southeast with a speed from five to seven meters per second. As the project manager Bruce Banerdt told, record of this noise was "unplanned pleasure". Noise of the Martian wind was written down by SEIS seismograph. As is well-known such devices are used for measurement of earthquakes. InSight seismograph which is still not used directly could register fluctuations of panels of solar batteries from wind. Except a seismograph for registration of the fluctuations caused by wind on Mars the air pressure sensor was also used. Liquid water on Mars. As made discovery "Urgently: people never heard a wind sound on Mars up to this point! Listen to the sounds of Mars which are written down by InSight when the Martian winds twisted our landing module. It is better to listen in earphones or with a subwoofer", - the director of NASA Jim Braydenstayn wrote to Twitter. As the seismograph is still fixed on the building of the platform, all InSight is one big ear reacting to fluctuations of the Martian air. However soon the seismograph by means of a robotic hand will be established on the surface of the planet and will not be able to write down fluctuations of the landing platform more. Examined himself and vicinities of Mars After landing to the Red planet on November 26 InSight successfully deployed solar panels and transferred the first pictures to Earth. They showed that the device is in small, the shock crater which is filled up with sand and dust, and is a little inclined sideways. Scientists did not find the large stones and other obstacles capable to interfere with work of a drill and observations of marsotryaseniye. The last two weeks members of a mission test devices and the systems of the station. So, already dipped a 2.4-meter robotic hand of IDA (Instrument Deployment Arm). On it the IDC camera (Instrument Deployment Camera) which will help scientists of NASA to choose places for placement on soil of devices is fixed. The sensor of pressure recorded air pressure drop. Scientists assume that falling was caused by the "dust devil" (the air whirl which is kicking up dust, sand and stones from a surface) passing pobliizost. Besides, InSight sent photos of Mars and Earth before landing. Mars, in process of approach of the device InSight: The researcher of a subsoil of Mars the Last time of NASA started the device to Mars in 2011, it was the rover Curiosity which works still. InSig
