Insight will use the next two years to collect and return rich data to determine how Mars is formed, improve understanding of the basic size of Mars, thickness of the mantle and 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 photo on Mars. The dust cover of the lens has not yet been removed, but I can't wait to show you my new home. Official representative of NASA InSighttwitterThe first image taken by InSight on Mars was released and the text was published.
On May 5, 2018, Insight was launched from Vandenberg Air Force Base in California. Six and a half months later, 300 million miles of interplanetary flight, the Insight was around 2:40 pm on November 26, US Eastern Time. More than 12,000 miles per hour reached the summit of the atmosphere of Mars.
The subsequent landing process was ridiculed by NASA and described as "Thrilling Seven Minutes." Since the entire landing process was completely based on pre-calculated and programmed programs, on the back of NASA it was not possible to remotely monitor understanding at this time.
Eventually, Insight landed in the middle of a plain in the northern hemisphere of Mars, near the Martian equator, 373 miles from the landing site of Mars of Curiosity. Interestingly, the launch time for Curiosity happened on November 26, seven years ago.
Explore the interior of Mars
“Three legs, one hand”, after weighing 360 kilograms of insight, two discsSolar powerThe panel unfolds and gives insight, like a wing. After the Health Insights is confirmed, the robotic arm will deploy the instrument on the surface of Mars. A NASA official said that it would take 2-3 months to operate the device.
This time, Insights basically brought three devices. The first is a seismograph of the French-made internal structure (SEIS), which is highly sensitive and can experience ground movements that are smaller than the radius of the hydrogen atom. Scientists expect to see at least 12 or even up to 100 earth vibrations in this mission, and the data will help scientists determine the depth, density, and composition of the Martian core, mantle, and crust. In addition, a heat sensor and physical property detection (HP3), provided by the German Space Agency, a rope sensor can penetrate deep beneath the surface to measure changes in temperature and heat sources. The third rotation and internal structure detector (RISE) provided by NASA JPL (Jet Propulsion Laboratory), based on the translation and rotation of Mars, caused the position of the detector to change to reveal the characteristics of the Martian core.
The Insight's successful landing also brought another surprise.
With the launch of epiphany, there are two miniature cubic satellites 36.6 cm long * 24.3 cm * 11.8 cm. Mars Cube One. Although they only have the size of the "portfolio", they played a huge role. They are called "Walley" and "Eve." Two satellites provided real-time signal relay services when the Insights landed, and NASA’s ground engineers understood the detailed Insights landing process. It also means that for the first time, people used microsatellite technology in interplanetary navigation, which engineers consider to be a cheap alternative to larger and more complex aircraft.
Fill another space
In November 1962, the Soviet Union launched the detector "Mars 1", which was considered the beginning of human intelligence on Mars. Since the eighth detector successfully landed on Mars, Insights performed a different mission than the past. Unlike previous detectors, Insights do not need to move, but stay in the depths to complete the first mission of human intelligence on Mars.
Insight will use the next two years to collect and return rich data to determine how Mars is formed, improve understanding of the basic size of Mars, thickness of the mantle and crust, and determine the internal temperature of Mars. In turn, it "reproduces" the formation of the Earth and other rocky planets in the solar system. “The reason we study Mars is not only to better understand Mars, but also in the Earth itself,” said Bruce Banderdt, principal investigator for Insight.
James Green, director of NASA's planetary science department, said: "The tectonic activity of the earth's crust destroyed most of the early history, but most of Mars, about one third of the Earth, remains almost static, which gives scientists a geological time machine." Bruce Banderdt also elaborated on this point of view, mainly using Mars as a time machine, going back to tens of millions of years after the formation of the Earth. Understand what makes the living earth, and what makes the desert Mars.
Scientists believe that there can be life and liquid water on Mars. If this is confirmed, people will open a new living space. From July 15, 1965, the Sailor 4 flew over Mars and returned the surface of Mars. At the beginning of the first image, the NASA Mars study did not stop. NASA recently announced that in 2020 it will launch a Mars rover march, landing on the crater Jezero, which used to be a 30-kilometer lake. NASA hopes to find signs of life.
