This is not known It's hard to get to Mars, but Nasa has recently headed her InSight Lander. From childhood on, I enjoyed seeing landing and space exercises on TV – a feeling of joy that has always been one another. But he prepared me for a sense of control over the mission he was working on. During the seven-minute silence in InSight, the quietness of the period resembles eternity, and over time, the system engineer Christina Szalei repeatedly used the interview. I will never forget the moment when I announced the "touchdown confirmed".
The InSight mission has been planning for more than 10 years. Among the planetary missions this is a bit of handball. Although many missions are designed to look at the surface or atmosphere of planetary bodies, the purpose of InSight is to explore the deepest surface of the planet – it helps to reveal the secret of how it and other rocky planets came into being.
Lander will perform a number of tools, including seismic meters, heat sink zones, magnetometers and radio receivers. Thermal flow and physical properties study (HP3) dropped fivefps from the surface of the Mars, up to a half of the missions' arm exercises. His measurement shows how quickly he loses heat from the interior of our planet – Mars helps us to understand how the time has cooled.
Rotation and Inner-Substrate Experiment (RISE) significantly reduces earth-borne radios. The difference between the frequency of the first and return signal can be used to determine the speed of InSight Lander Earth, otherwise, the sirens will show that they are moving away from us or from us. We are particularly interested in using speed to tell you how the Mars axis is changing over time. The size of these waves depends on the interior structure, especially on the core of its dense metal. When turning on a flat surface, Mars is weakened with a lot of fluid, rather than a hard boiled egg.
I work on Seismic Experiments for an internal structure of two seismic meters, which is installed in the grinding system at a height of 15 cm above the Mars surface. This experiment is intended to determine the number of seismic activity in Mars. Also, the time of seismic waves reaching the seismometer is the temperature and composition of the internal dispenser.
We now have more than three months to launch and launch the tools. In the next few days, the health of the system will be checked, and the inspector will be able to decide where to place the heat flow and the seismometer. The first picture from the surface suggests that we have landed on a sandy-filled crater, so several variants appear.
In the middle of December, the robotic signature seals the seismic launchers on the piston deck and shoot them. After thorough inspection, the grinding system is used to ensure that seismometers are transverse. By mid-January a shield should be placed on the seismometers to protect them from the elements. Then you can add them and place the heat sink ion.
The heat flux probe begins to return data, which begins at the bottom of the page so we hope to achieve results in the first half of 2019. The radio experiment will take much longer. That's how it is not good to see the noise of the Mars pole next year. It will change in the middle of 2020, and we have to be very comfortable in revealing the secrets of our secrets.
As for the EEIS experiment, when we see an interesting thing about how often a seismic energy exits. We do not know about it now. We know that there are two possible sources of seismic activity: "marquises" that are caused by the effects of meteorite and faults near the surface.
We know that meteorites have often sailed, but the movement of defects is mysterious. By the Earth, Mars has no moving tectonic plates, so it is assumed that the planet's internal cooling will cause a defect movement. However, some of the youngest defects in Mars are formed not by cooling, but by the movement of molten rock. Helps determine the exact causes of the frequency and nature of the mask.
Through its three main experiences, InSight gives a "picture" of the present-day status and the composition of Mars. But this science news is not over. Ultimately, the mission will help us understand 4.5 billion years ago when the solar system is very young.
The main key
That is why. It is determined when the composition of the planet occurs, in the case of Mars, several million years after the sun had risen. Because we are at greater distances from the sun, we think that Mars is made up of diverse, highly volatile materials than Earth. However, it is very difficult to test and develop this idea until Mars's composition is known. Data from InSight provide a key to how the rocky planets in our solar system can be formed and how we can understand other stars.
The composition, temperature, and magnetic fields of our planet are essential for sustaining life on our planet. Thus, although InSight does not aspire to live, four billion years ago, it gives new insight into how the Earth affects its own life.
InSight has already been a great engineering achievement, and the science team now has a great opportunity to use it to unravel the mystery of Mars. We hope you are as excited as we are.
