Insight ho … began to investigate possible human settlements

On the 26th, at 04:54 (local time), the shock was launched at the static propulsion (JPL) static propulsion laboratory. NASA's "InSight" rocket finally landed safely on the "skin" of Mars. The landing site was the plain of Elysium, near Mars Equator. It was not just JPL. People who watched the landing at Times Square in Manhattan, NY, were also enthusiastic.

NASA TV has clearly communicated the interviews of JPL researchers participating in this mission. Rob Manning, senior engineer at JPL, is "flawless", "That's what we really hope and imagine in our minds – it's really fantastic." Vice President Mike Fence, who heads the National Commission from the United States space, has qualified as "eighth time the United States landed on Mars and the first mission to explore the deep interior of Mars".

This is the eighth time that NASA has sent a probe to Mars, as Fens said, but it's the first mission to explore below the surface. InSight is an abbreviation for "indoor exploration using seismic surveys, geodesy and heat transport", which stands for internal exploration using seismic surveys, geodetic and thermal transport. Insight plans to harness geothermal heat and seismic waves by digging at depths of 5 meters with a robotic arm in the Elysium Plain near the enemy landing site. Because it is a fixed probe, it does not move to the point of landing.

What can we know from 5m exploration? A researcher from the Korean Institute of Aeronautics and Space (KAERI) said: "If we penetrate up to 5 meters below the surface of Mars, we can explore the variation the geothermal temperature of Mars by 1 meter. " "I can see how active it is."

The "degree of activation of the Mars Core" of Insight is a clue to whether life can live on Mars, which is considered a powerful colonization in the future. Choi Ki-hyeok, researcher in charge of the project, said: "The elements of the planets circulate when the movement of the Earth is generated by nuclear activation." The fact that life can live in abundance on Earth is due to the movement of the Earth for hundreds of millions of years. "He said.

Atmospheric conditions, which are essential living conditions, are also determined by the nucleus. The "magnetic field" of a planet that occurs when the iron component rotates in the nucleus must be able to retain the atmosphere. Choi explains that the state of the atmosphere of Mars can be apprehended more precisely depending on the composition and level of activation of the kernel.

Insight will use its SEIS seismic and HP3 thermal sensor to detect geothermal and seismic activity over the next two years to determine the state of Mars "planet." We also plan to investigate whether Mars is liquid or solid by measuring the "wobbling" that occurs when Mars rotates using two RISE X-band antennas.

There is also an interpretation that this geological study on Mars has begun the direct preparations for the human exploration of Hwaseong. Hwang Jin-young, a researcher, said: "The X space and other space companies having already formulated the construction plan for the Hwaseong settlement, they can be considered a preparation for this operation." According to Hwang, Hwang is able to optimize the "residence module" on which astronauts can search. On the other hand, preparations for such human exploration by Hwaseong have been made possible through an extremely difficult landing process called "entry, descent and landing (EDL)".

The atmosphere of Mars is so thin that it only accounts for 1% of the Earth's thickness and it can not expect a natural reduction in speed due to friction with the atmosphere. Insight, flying at a speed of 17,994 km / h, had to reduce the speed to zero by exceeding an atmosphere of 128 km long on Mars in 6 minutes and 30 seconds. To pbad this course with a success rate of about 40%, Insight is rated to overcome the "seven minutes of fear".
