For the eighth time, NASA landed on Mars. What enters the view of Mars? _ Fortune Eastern Network



Insights will be used for the next two years to collect and recover rich data to distinguish how Mars forms, improve the understanding of Martian nucleus, the size and thickness of the crust, and determine the internal temperature of Mars. In turn, the formation of the Earth and other rocky planets in the solar system is reproduced.

This is my first photograph of Mars. The legal lens cover has not yet been recorded, but I can not wait to show you my new home. NSA's official InSightTwitterThe first image captured by InSight on Mars was released and the text was released.

On May 5, 2018, the insight was released from Wendenberg's California Air Force Base. After six and a half months, 300 million miles of interplanetary flight, the Insight was around 2:40 on November 26th, the US Eastern Time. More than 12,000 miles per hour reached the peak of the Mars atmosphere.

The next landing process was joked by NASA and described as "exciting seven minutes". Since the entire landing process relies entirely on pre-calculated and programmed programs, the back NASA could not remotely control the inspection at that time.

Eventually, Insight landed in the middle of the plane of the northern hemisphere on Mars, near the Martian Equator, 373 miles from the Mars landing site of curiosity. Interestingly, the timing of the curiosity launch took place on November 26, seven years ago.

Explore the interior of Mars

"Three legs, one hand" after measuring 360 kilograms of insight, two disc-shapedSolar energyThe panel develops and gives insights as a wing. After confirming the health of the Insight, the robotic arm will deploy the instrument on the surface of Mars. A NASA official said it would take 2-3 months for the device to function.

This time, Insight mainly brought three devices. The first is the seismograph of the internal structure of the French (SEIS), which is very sensitive and can test the field movements that are smaller than the radius of the hydrogen atom. Scientists expect to see at least 12 or even 100 vibrations in this mission, and the results will help scientists to determine the depth, density, and composition of the core, mantle and crust from Mars. In addition, the heat flow and the detector of physical properties (HP3) provided by the German space agency, the rope probe can penetrate deep under the surface to measure temperature changes and heat sources. The third rotational and internal structure detector (RISE) provided by NASA JPL (Jet Propulsion Laboratory) based on the revolution and rotation of Mars has caused the detector's position to change to reveal the characteristics of the core of Mars.

Successful landing of Insight also brought a new surprise.

With the launch of the insight, there are two 36.6cm * 24.3cm * 11.8cm Mars Cube One miniature cubic satellites. Even though they only have the size of the "handbag", they play a huge role. They are called "Walley" and "Eve". Both satellites provided signal services in real time, when Uves landed, and NASA engineers could understand the detailed landing process of the Insight. This also marks the first time people have used microsatellite technology in interplanetary navigation, which engineers consider to be a low cost alternative to larger, more complex planes.

Fill another gap

In November 1962, the Soviet Union launched the Mars 1 detector, which was considered the beginning of human research on Mars. As the eighth detector for successful landing on Mars, the Inspectors wore a different mission from the past. Unlike previous detectors, Insights should not move around, but remains in depth in the direction of performing the first human exploration mission on Mars.

Insights will be used for the next two years to collect and recover rich data to distinguish how Mars forms, improve the understanding of Martian nucleus, the size and thickness of the crust, and determine the internal temperature of Mars. In turn, it "reproduces" the formation of the Earth and other rocky planets within the solar system. "The reason why we study Mars is not only better to understand Mars, but the Earth itself," said Bruce Bannertte, Insight's chief researcher.

James Green, director of NASA's Planetary Science Department, said: "Earth's territorial tectonic activity has destroyed most of the early history, but much of Mars, about one-third of the Earth, remains almost static, which provides scientists Geological Time Machine ". Bruce Bannertte also elaborated on this point of view, basically using Mars as a time machine, returning tens of millions of years after the formation of the country. Understanding what makes a living earth, and what makes the empty Mars.

Scientists believe that Mars can have life and liquid water. If this can be confirmed, human beings will open up a new living space. From July 15, 1965, "Mornar 4" flew over Mars and returned the surface to Mars. At the beginning of the first picture, the NASA Mars Survey did not stop. Recently, NASA announced it will launch the Mars Rover in 2020, landing on the Jerez crater, which is used to be a 30-mile lake. NASA hopes to find signs of life.
