Detector "Insight"

Scientists with red shirt models caught nervously on the big screen, and showed a keen insight for success.

"400 meters, 300 meters, 200 meters, 80 meters from the ground …" When the landing was able to return sound "哔 哔" (indicating that the detector was still "alive, b & # 39; his health" ), researchers pursued in the Cheering, hugging, applauding … Celebrating humans b & # 39; different ways again & # 39; other, after six years, managed landed in & # 39; Mars once & # 39; other. This man has been focusing on and detects the red planet for nearly 60 years.

Researchers of the Center Commands celebrated the "Insight" b & # 39; & # 39 landed in success; Mars

"Today, we have completed eight landing b & # 39; & # 39 success in; Mars in human history. We will Shifting astronauts to the moon and then Shifting astronauts to Mars." Insight "will provide valuable scientific information before show to Mars." NASA Director Jim Bridenstine said excited after landing b & # 39; success.

NASA reported that 14: 52: 59 EST 26 & # 39; November (time & # 39; Beijing in 3: 52: 59), the probe "Insight" Mars ends with & # 39; success in & # 39; Mars. This is the August 5, 2012 "Curious" Rover b & # 39; success landed in & # 39; Mars, detectors man again & # 39; other b & # 39; landed success on the surface & # 39; Mars.

"There" drum sound "underground, we need studying the interior of & # 39; Mars'

When it comes to project & # 39; exploration & # 39; Mars in the United States, most people think about the Mars rover, like Opportunity and Curiosity, seen frequently in the media in & # 39; in recent years, especially Opportunity, which has life & # 39; design & # 39; only 3 months. I stayed & # 39; for 11 years, not only have achieved fruitful results, but also created a world record for "accidents" on Mars – lasted more than 40 kilometers and ran marathon & # 39; "Mars".

The United States began the launch of Mars probe "Sailor 4" in 1964, and continued exploration of & # 39; Mars for more than 40 years, and have gained a large number of & # 39; results & # 39; detected. As with most crops from Mars, the US is still on Mars.

The expert & # 39; the space Pang Zhihao Yu told News that although we have been exploring & # 39; Mars for the first time in & # 39; & # 39 decades, years, we know little about the internal structure of & # 39; Mars. Previously, the total number of & # 39; & # 39 explorations; Mars performed by humans was to review the overall camps, surface, atmosphere and magnetic & # 39; Mars. The "Insight" detects the interior & # 39; Mars for the first time, equivalent to "scanning of the first physical exam in & # 39; 4.5 billion years" on a CT scan.

"Insight" will perform the first human task & # 39; discovery & # 39; Mars inside.

The first word "know people know someone 'is also applicable to the field of exploration of deep space. For a planet to discover, if you know only the earth and its atmosphere, it knows only her face and can not understand the core of & # 39; its interior. Yang Yuguang, deputy chairman of the International Transport Committee & # 39; the Astronawtiku Space, said the news: "Send a few detectors to move around the planet or on the ground. The Kepler 452b exoplane , although similar in size and size to Earth, still unable to know whether a rocky planet, not to mention the interior of the Earth structure. Therefore, to fully understand planet, has the identification of the structure interior of the Earth. "

According to information published before NASA, "Insight" mainly performs two major scientific tasks: first, to determine the actual Martian geology as discover the scale, frequency and geographical distribution of internal seismic activity & # 39 , Mars and frequency of meteorite impacts on the surface of & # 39; Mars. The level & # 39; tectonic activity; the second is to study the formation and evolution of terrestrial planets by investigating the structure and activities of internal & # 39; Mars. press

According to the task, the researchers developed six survey items: determine the size, composition and physical state of the Martian core, determine the thickness and the Martian crust structure; The size, speed and geographical distribution of seismic activity; Measuring the rate of impact of a meteorite on the surface of & # 39; Mars.

Bruce Bennett, the principal project "Insight", told Nature that despite the long history & # 39; exploration & # 39; Mars, mostly, there were some scratches in the surface of the Earth. "For 35 years, there has been a" drum "which comes from the land. We studying the interior of & # 39; Mars", said Bruce Bennett.

"Deepen the understanding of the World neighbors"

The "Insight" was b & # 39; 5 success & # 39; May this year. After launching, took 485 million kilometers, which lasted more than six months. The "Insight" is linked by & # 39; inseparable way to Lander "Phoenix" which issued on Mars in 2008. Therefore, some media also refer to the "Insight" as "Phoenix" 2.0. The "Insight" using the detector platform of Phoenix, so "Insight" is very similar to the Phoenix detector in appearance, but is partly adjusted to the task. The "Insight" is & # 39; about 5.5 meters long and is about the size of & # 39; small car with & # 39; & # 39 mass; 350 kilograms. In addition, there are two circular solar panels can be used as paper fans.

Steps to upload & # 39; b & # 39; success on Mars

"The first 'Phoenix' landing on the Arctic plains & # 39; Mars and achieved many results related to freezing, water and soil frozen the Arctic plain. More than 5% & # 39 ; water, Dewdrop on the feet & # 39; landing, found the features of & # 39; water. "said Zheng Yongchun, a researcher at the National Astronomy Observatory & # 39; Chinese Academy of Sciences and planetary expert.

According to previous reports the average & # 39; the United States, the site location & # 39; landing was & # 39; four & # 39; years. The coordinates & # 39; the final descent were selected: 4.5 ° latitude & # 39; north and longitude 135.0 & # 39; east. Because the land is flat, m & # 39; there is no channel, and plenty of sunshine to ask the solar panels. In addition, the site & # 39; landing is & # 39; 600 kilometers from Mars "Curious", and can & # 39; communicate with five orbital probes & # 39; Mars currently active. To ensure the needs of & # 39; the parachute guard during the process & # 39; landing, the point & # 39; landing should be less than 2.5km under ġeojose Martian. And drill hole & # 39; 5 meters deep.

"Since 1965, we studied Mars from orbit and the surface to understand weather, atmosphere, geology and chemistry of surface & # 39; Mars", said Lori Glaze, Director Assets of the Department of Science Planetary in NASA Scientific's mission. Recall that "Now, as NASA prepares to send human explorers deeper into the solar system, will eventually explore the interior of & # 39; Mars and deepen our understanding of the Earth's neighbors."

To enhance understanding of the World neighborhood, the "Insight" will carry three different scientific loads, including two instruments provided by Europe, designed to jisaminaw the heart in deep red planet. Includes sismografu equipment, value detectors geothermal flow and equipment & # 39; detection & # 39; 'Rotation and internal structural test ". The equipment of the seismograph and the value of the geothermal flow detectors were developed by France and Germany, respectively. In addition to the three types of & # 39; & # 39 devices; discovery & # 39; above, is equipped with & # 39; both cameras to measure pressure, temperature and wind speed & # 39; Mart. Material.

"Use & # 39; sismografi to discover waves & # 39; earthquakes inside, an earthquake inside Mars are natural earthquakes, and some are earthquakes caused by internal activities & # 39; Mars. Some asteroids and meteorites will affect to Mars to cause some vibrations. " Zheng Yongchun introduced Said, "The propagation of seismic waves will reflect the signal. According to the interpretation of the signal, you & # 39; obtaining data & # 39; the internal structure and composition & # 39; Mars. Problems like the basement. "

"The earthquake is a very important tool for us to understand the internal Earth, Mars inside and inside the Moon." Yongchun Zheng added.

The flow of heat detector is mainly to measure the temperature and gradient & # 39; certain facial fund & # 39; Mars. By multiplying the temperature gradient of the measured substance and the thermal conductivity of the substance, it is possible to calculate the heat flux through the core of the heat flow per unit area. Situation.

According to relevant data, the heat flow can & # 39; is used to understand the release of internal energy. The release of energy is achieved by deleting & # 39; internal radioactive elements, and b & # 39; as assessing internal heat & # 39; Mars. The initial situation & # 39; you & # 39 Mars; deducing b & # 39; pattern, such as a radioactive elements in & # 39; at that time, and how much heat inside the current Mars, and the question is about the history of internal thermal evolution and structure internal & # 39; Mars. Layers.

In short, the sismometri used to find the stratification of the internal structure of & # 39; Mars, while the heat flow meter is a thermal history & # 39; inside & # 39; Mars.

"Another example of & # 39; international cooperation in the exploration of deep space"

The "Insight" project is a project & # 39; in-depth exploration of & # 39; international cooperation. "This achievement represents the wisdom of the United States and our international partners and shows the dedication and perseverance of our team", said the Director of the NASA Jim Briddenstein. CNN reported that after the visit of & # 39; success & # 39; "Insight", the President of the United States Peng Si called to congratulate to the whole team.

On the detector "Insight", the seismograph was developed by France, and the detector heat flux was developed by Germany, and these two are two of the most important instruments of the detector.

"Insight" in the text

"The landing b & # 39; success in & # 39; Mars has established the foundations for work & # 39; future exploration. If the project is completed b & # 39; successful, then" Insight "will become another example & # 39; international cooperation in the exploration of deep space. " Pang Zhihao believes.

Of & # 39; worth mentioning that the mission "Insight" will also use two mikrosatelliti to provide experimental in & # 39; real-time signals & # 39; relevance to the World during the phase & # 39; landing. This is also the first time in the mission of deep space to use "Star Micro Satellite"

Both mikrosatelliti used in mission "Insight" called "Mars One Cube" and will be launched with "Insight" and embark on a journey to Mars. When the "knowledge" landed in & # 39; Mars, they fly past Mars and transmit data & # 39; landing of the "number & # 39; awareness" to the satellite of -devjazzjoni Earth. According to NASA, "Mars One Cube" is like satellite relay of the landing detector "Insight", which can & # 39; greatly improve the efficiency of the transmission signal & # 39; "Insight". Explore further interstellar missions of the solar system.

"Mars Cube One" is just a pilot project, and therefore the communication relays can not rely on "two brothers". Yang Yuguang said: "As the mission & # 39; & # 39 release;" Insight Number ", Mars Reconnaissance Orbiter adjusted the orbit to meet the number of & # 39; Insight received in 2016. You & # 39; help the" Insight Number "is calibrated in orbit, as" Providing Orbit a & # 39; accurate descent, and personally witness 'knowledge' in Martian atmosphere and process & # 39; landing, store and record data.
