The eighth time NASA landed on Mars What is the content of Insight in Mars? _ Eastern Fortune Network



Insight will use the next two years to collect and restore rich data to illustrate how Mars formed, increase understanding of the size of the Mars core, mantle and crust thickness, and determine the internal temperature of Mars. In turn, the formation of Earth and other rocky planets in the solar system is reproduced.

This is my first photo on Mars, the lens dust cover hasn't been taken, but I can't wait to show my new home. NASA Official OfficerTwitterThe 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, California. After six and a half months, 300 million miles of interplanetary flights, Insight around 14:40 on November 26, US Eastern Time. More than 12,000 miles per hour reaches the peak of the Martian atmosphere.

The next landing process was joked by NASA and described as "Thrilling Seven Minutes." Because the entire landing process relies entirely on programs that have been calculated and programmed, the rear NASA cannot control the view from a distance at this time.

Finally, Insights landed in the middle of the plain in the northern hemisphere of Mars, near the Mars equator, 373 miles from the landing site of Mars Curiosity. Interestingly, Curiosity's launch time occurred on November 26, seven years ago.

Explore the inside of Mars

"Three feet, one arm", after weighing 360 kilograms of insight, two disc-shapedSolar energyThis panel opens and strengthens insights such as wings. After health insight is confirmed, the robotic arm will spread instruments on the surface of Mars, NASA officials say that it will take 2-3 months for the device to operate.

This time, Insight mainly brought three devices. The first is the internal structure of a French-made seismograph (SEIS) that is very sensitive and can test the motion of the soil that is less than the radius of a hydrogen atom. Scientists hope to see at least 12, or even up to 100, ground vibrations in this mission, and the resulting data will help scientists deduce the depth, density, and composition of the core of Mars, mantle and crust. In addition, heat flow and physical property detectors (HP3) provided by the German Space Agency, rope probes can penetrate far below 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) are based on the Martian revolution and rotation, causing the position of the detector to change to reveal the characteristics of the Mars kernel.

The successful landing of Insight also brought another surprise.

With the launch of insight, there are two 36.6cm * 24.3cm * 11.8cm Mars Cube One cubic miniature satellite. Even though they only have the size of a "suitcase", they have played a big role. They were named "Walley" and "Eva." Both satellites provide real-time signal relay services when the Insight lands, and NASA engineers in the field are able to understand the detailed landing process of Insights. This also marks the first time humans have used microsatellite technology in interplanetary navigation, which engineers consider a low-cost alternative to larger and more complex aircraft.

Fill in another gap

In November 1962, the Soviet Union launched the "Mars 1" detector, which was seen as the beginning of human Mars exploration. As the eighth detector that successfully landed on Mars, Insights brought a different mission from the past. Unlike previous detectors, Insight does not need to roam, but remains in a deep direction to carry out the first human exploration mission on Mars.

Insight will use the next two years to collect and restore rich data to illustrate how Mars formed, increase understanding of the size of the Mars core, mantle and crust thickness, and determine the internal temperature of Mars. In turn, it "reproduces" the formation of Earth and other rocky planets in the solar system. "The reason we study Mars is not only to better understand Mars, but also the Earth itself," said Bruce Banerdt, chief investigator of Insight.

James Green, director of NASA's planetary science department, said, "Tectonic tectonic activities of the earth have destroyed most of the early historical sightings, but most of Mars, about a third of the Earth, remains almost static, giving Engineers geological time. describes this point of view, basically using Mars as a time machine, returning to tens of millions of years after the formation of the earth. Understand what makes the earth alive, and what makes Mars barren.

Scientists believe that there might be life and liquid water on Mars. If this can be confirmed, humans will open up new living spaces. On July 15, 1965, "Sailor 4" flew over Mars and returned the surface of Mars. At the beginning of the first image, NASA's exploration of Mars did not stop. Not long ago, NASA announced it would launch Mars rover by 2020, landing on Jezero Crater, which used to be a 30-mile lake. NASA hopes to find signs of life.
