 The United States launches insight first to explore Marss heart


The insight task, called internal exploration through seismic survey, geodesy and heat conduction, is the first to study the mission of the interior of Mars. It is also an important part of the unmanned Mars exploration project in the United States. It is designed for two years. Scientists hope to understand the size, composition and physical state of the Martian core, the geological structure, and the internal temperature and seismic activity of Mars through the insight. The Mars probe is equipped with two collapsible solar panels, which are about 6 meters wide after the launch. The insight is equipped with three main scientific instruments, namely, seismological instrument, temperature measuring device and rotating and internal structure experiment instrument. The windproof seismological meter is very sensitive enough to perceive the ground motion of the radius of the hydrogen atom, to record the shock waves caused by the Mars shock or the impact of the meteorite; the temperature measuring device can measure the heat of the release of the Mars core by hammering to 3 meters or more deep underground, and rotating and internal structure is real. The instrument can be used to assess the disturbance generated by the rotation of the Mars axis through the radio transmission between Mars and the earth, so as to provide clues for the size of the Mars core. In addition, the two twin mini satellites, named by the cartoon star Wali and Eva, will go together with the insight to become the first of the cube satellites to enter interplanetary space. They will direct the remote telemetry results back to earth when the insight is landing. The cost of the two satellites is about $18 million 500 thousand. The insight was originally planned for launch in March 2016. However, due to the lack of vacuum sealing in the main sensors of its seismological instrument, the launch was delayed. A previous statement issued by the US space agency said the insight had a budget of $675 million, but the redesign of the seismological instrument and the delay in the mission resulted in the cost of more than $993 million.
