Eighth time when NASA landed on Mars. What are the data that fill the gaps on Mars? _ Fortune East Network



Insight will use the next two years to gather and return rich data to determine how Mars was formed, to improve understanding of Martian core size, shell thickness and bark, and to determine Mars' internal temperature. On the other hand, the creation of Earth and other rocky planets within the solar system is reproduced.

This is my first photo on Mars. The dust cap of the lens has not yet been received, but I can not wait to show you my new home. NASA InSight OfficialTwitterThe first shot taken by InSight on Mars was released and the text was published.

On May 5, 2018, Insight was launched from Vandenberg Air Base in California. After six and a half months, a 300 million mile interplanetary flight was Insight around 26:40 on November 26th in US Eastern Time. More than 12,000 miles an hour reached the summit of Mars.

The subsequent landing process was joked by NASA and described as "Exciting seven minutes." Given that the entire landing process relied solely on pre-calculated and programmed programs, NASA's back could not at this time have remote control.

Eventually, Insight appeared in the middle of the plane in the northern hemisphere of Mars, near the Martian Equator, 373 miles from the Mars of Curiosity. Interestingly, the time of commencement of curiosity happened on November 26, 7 years ago.

Explore the interior of Mars

This time Insights acquired three devices. The first is a French-made internal SEIS that is highly sensitive and can test ground movements that are smaller than the radius of the hydrogen atom. Scientists expect at least 12 or even 100 earth vibrations in this mission, and the resulting data will help scientists derive the depth, density and composition of the Martian core, shells and bark. In addition, the Heat Detector and Physical Properties Detection (HP3) provided by the German Space Agency, the cable probe can penetrate deep beneath the surface to measure temperature changes and heat sources. The third Rotational and Internal Design Detector (RISE) provided by the NASA JPL (Jet Propulsion Laboratory) based on the revolution and rotation of Mars caused a change in the position of the detector to reveal the properties of the Martian core.

Insight's successful landing brought another surprise.

At the start of the survey, there are two miniature cubic satellites measuring 11.6 cm (12.6 cm) and 24.8 cm (11.8 cm). Although they only have the size of a briefcase, they play a huge role, they are called "Walley" and "Eva." Two satellites provided real-time signal relay services when immigration landed, and NASA engineers on the ground were able to understand the detailed landing process in the preview. This also means that for the first time people use microsatellite technology in interplanetary navigation, which engineers see as a cheap alternative to larger and more complex aircraft.

Fill the next space

In November 1962, the Soviet Union launched the "Mars 1" detector, which was considered the beginning of a human Mars survey. As the eighth detector successfully landed on Mars, Insights carried a mission other than the past. Unlike previous detectors, Insights statistics may not wander, but they will remain in depth to conduct the first reconnaissance mission to Mars.

Insight will use the next two years to gather and return rich data to determine how Mars was formed, to improve understanding of Martian core size, shell thickness and bark, and to determine Mars' internal temperature. On the other hand, it "reproduces" the formation of Earth and other rock planets within the solar system. "The reason why we are studying Mars is not only to better understand Mars but also Earth itself," said Bruce Banerdt, chief investigator for Insight.

James Green, director of NASA's Planetary Sciences, said: "Earth's crust tectonic activity has destroyed most of the early history, but most of Mars, about one-third of the Earth, remains almost static, giving scientists the Geological Engine of Time." Bruce Banerdt view, basically using Mars as a time machine, which has returned to the tens of millions of years after the birth of the Earth. Understand what makes the living Earth and what makes the empty Mars.

Scientists believe that Mars can be life and liquid water. If this can be confirmed, human beings open a new living space, and since July 15, 1965, Sailor 4 has flown to Mars and returned to Mars. At the beginning of the first image, NASA did not show up on Mars. NASA has recently announced that it will launch the Mars rover in 2020 and land on a lake crater, which was previously a 30-mile lawn. NASA hopes to find signs of life.
