天问一号飞運騎遊達达3亿 …….As of 26th   March 2021, CNSA – China National Space Administration– ESA – European Space agency Belt and road initiative mars mission…first Mars exploration mission, Tianwen- Martian Probe One ……. With the China National Space Administration released two sideways images of Mars in the southern and northern hemispheres taken by my country’s first Mars exploration mission, Tianwen-1. In the image, Mars has a “crescent” shape with clear surface texture. The Tianwen-1 probe flew to a distance of 11,000 kilometers from Mars and used a medium-resolution camera to take a panoramic view of Mars. At this time, because the probe is in the sky behind the Mars side (to face the sun as the front), two “sideways” images are obtained. At present, the Tianwen-1 probe has been in orbit for a month, and the high-resolution camera, medium-resolution camera, mineral spectrometer, Mars energy particle Analyzer, ion and neutral particle Analyzer, magnetometer and other loads have been turned on one after another. , Carry out exploration of Mars and obtain scientific data.

The southern hemisphere image was taken by the Tianwen-1 medium-resolution camera on March 16, 2021, Beijing time. At this time, the orbital height of the orbiter was about 11,200 kilometers.

The northern hemisphere image was taken by the Tianwen-1 medium-resolution camera on March 18, 2021 Beijing time. At this time, the orbital height of the orbiter was about 11,500 kilometers.

Tianwen-1 is currently in the mooring orbital phase, and all seven orbiter payloads have been powered on for preliminary scientific exploration, to achieve stable communication between the Earth and Mars, and to provide signal relay services for future patrols landing on Mars. Every two days, it arrives at a near-fire point, only about 280 kilometers away from Mars………

After 3 months of detailed surveys, the orbiter will undergo a certain orbit adjustment and be separated from the lander/patrol unit. The latter will start an independent Mars landing process of about 7 minutes. Due to the long distance between Mars and the Earth, which leads to a communication delay of tens of minutes, it is impossible for the CNSA crew to control the landing process, and must let the lander complete this “black seven-minute” journey fully autonomously…..

As of 22th March 2021 Monday, The CNSA –China National Space Administration Belt and Road Initiative Lunar Mission……Chang’e-4 successfully awakened completed the 28th day of the work period after the Chinese Lunar New Year – year of the OX  got  back to work  Chang’e 4 completed the 28th day of work……. The Chang’e 4 lander and the “Yutu 2” lunar rover finished their 28th day of work at 2 o’clock on March 21 and at 17:09 Hong Kong – Beijing Time  on March 20, and entered the moon night Hibernate. Up to now, the Chang’e 4 lander and the “Yutu-2” lunar rover have survived 808 Earth days on the moon. The lunar rover travelled about 30 meters during the day and the accumulated mileage was 682.77 meters…

Chang’e-4 completed its 28th day of work, and scientific research revealed the source of the stones in the inspection area

 

The Chang’e-4 lander and the “Yutu-2” lunar rover ended their 28th day of work at 2 o’clock on March 21 and at 17:09 on March 20, respectively, and entered moon night dormancy. Up to now, the Chang’e 4 lander and the “Yutu-2” lunar rover have survived 808 Earth days on the moon. The lunar rover travelled about 30 meters during the day and the accumulated mileage was 682.77 meters.

Researchers systematically analysed the detection data obtained by Chang’e-4, and obtained a series of scientific results on the mineral composition of the landing area, the history of topographic and geological evolution, the degree of lunar soil space weathering, and the shallow underground structure. Recently, the research results of the State Key Laboratory of Remote Sensing Science, Institute of Aerospace Information Innovation, Chinese Academy of Sciences, were published in the international journal “Journal of Geophysical Research: Planets”. By analysing the spectral characteristics of the stones in the inspection area, the scientific research team concluded that the stones are likely to originate from the ancient Finsen impact crater, and the spatial distribution characteristics indicate that they are freshly exposed impact crater spatters. These rocks were originally buried in the lunar soil after being sputtered by the Finsen impact crater. Later, they were exposed on the lunar surface due to the impact and excavation of the spatter from the Vega impact crater.

 

A number of studies revealed that the Chang’e-4 landing area was covered by spatter from the Finsen impact crater formed 3.5 billion years ago. After a long period of evolution, these spatters formed a layer of fine-grained lunar soil about 12 meters thick. During the 3rd and 13th day of the month, the “Yutu-2” lunar rover found more rocks in the inspection area (Figure 2). The “Yutu-2” lunar rover obtained the spectra of two representative rocks and a panoramic image of the surrounding landforms through detailed in-position detection.

The results of the spectral comparison show (Figure 3) that the spectral absorption characteristics of the rocks are closer to those of the Finsen impact crater material, but are quite different from the spectral absorption features of the basalt inside the von Karmen impact crater. This shows that these rocks are not native basalts, and they are most likely derived from the spatter of the Finsen impact crater.

The rocks discovered by the “Yutu-2” lunar rover during the 13th day of the month are mainly distributed around an impact crater. The overall density of the rocks gradually decreases as the distance from the impact crater increases, and some rocks are distributed in chains along a specific direction (Figure 4). The spatial distribution characteristics of the rocks indicate that they are sputtering from the current impact crater. The impact crater has an elliptical shape with a northwest-southeast direction along its major axis. The continuous (micro) meteorite impacts and the thermal expansion and contraction caused by the temperature difference between day and night caused the exposed rocks on the moon to gradually shatter and disappear within tens of millions of years. The large number of rocks remaining around indicates that the impact crater is a fresh impact crater, and the exposure time of these rocks is relatively short.

Research results have shown that a sputtering pattern of the Vega impact crater located in the northwest of the landing area just passes through the area near the landing site, and secondary impact craters formed by spatters are often seen in the splashing pattern. In the inspection area of “Yutu No. 2”, several fresh impact craters at the meter and sub-meter level with fragmented materials inside and around it can indeed be observed (Figure 5). Based on the inference of the long axis direction of the elliptical impact craters, these fresh impact craters should be secondary impact craters formed by the sputtering of the Vega impact crater.

Based on the above analysis, this study believes that the stones observed by the “Yutu-2” lunar rover actually originated from the ancient Finsen impact crater. They were originally buried in the lunar soil in the landing area. Later, they were impacted by the spatter of the Vega impact crater. Excavated and exposed to the moon’s surface. The dating of the Vega crater reveals that these rocks have existed on the lunar surface for about 16 million years (Figure 6).

Previously…..   天问一号飞運騎遊達达3亿 …….As of the afternoon Chinese Lunar New Year festival week holidays afternoon 4th March 2021, CNSA – China National Space Administration- ESA – European Space agency Belt and road initiative mars mission…first Mars exploration mission, Tianwen- Martian Probe One released three high-definition Mars image maps taken by China – People’s Republic of China first Mars exploration mission Tianwen-1 probe, including two full-color images and one color image……

The panchromatic image was taken by a high-resolution camera at an altitude of about 330 kilometers to 350 kilometers from the surface of Mars, with a resolution of about 0.7 meters. In the imaging area, small ring craters, ridges, sand dunes and other landforms on the surface of Mars are clearly visible. The diameter of the largest impact crater is about 620 meters. The color image was taken by a medium-resolution camera, and the picture shows the north pole of Mars.

Starting on February 26 2021, Tianwen-1 has carried out scientific exploration in the parked orbit, and scientific payloads such as the orbiter high-resolution camera, medium-resolution camera, and mineral spectrometer have been turned on one after another to obtain scientific data. The high-resolution camera on the orbiter is equipped with two imaging detectors, which can realize linear array push-broom and area array imaging, and carry out fine observation of topography and landforms in key areas. The medium-resolution camera has the functions of automatic exposure and remote control of exposure adjustment, and can draw global remote sensing image maps of Mars to detect the topography and changes of Mars Tianwen No.1 probe shoots high-definition Mars image…..

Black-and-white or color photos are related to the shooting mode. The high-resolution camera photos are taken by the linear array push sweep method when the detector is running on a large elliptical orbit. They are divided into full color, color, and custom. The full-color (i.e. black and white) image is the clearest, the data volume is the largest, and the scientific value is the highest. The definition of a color image is a quarter of that of a full-color image. After the image fusion processing of panchromatic and color mode, a clear and beautiful color image will be obtained. The medium-resolution camera has only one static shooting mode, which is to use the “gaze” shooting mode, so that the camera has been “gazing” at a certain area, and the overall resolution will be relatively low.

Mars moored orbit on the day. The probe will run on the berth orbit for about three months, and all seven orbiter loads will be turned on and scientific exploration will begin. At the same time, the medium-resolution cameras, high-resolution cameras, and spectrometers in the payload will conduct detailed investigations of the topography, landforms, sand and dust weather in the pre-selected landing area, and prepare for landing on Mars.

Since its successful launch on July 23, 2020, the Tianwen-1 probe has been in orbit for 215 days and is currently 212 million kilometers away from the earth. On February 10, 2021, the probe entered the ring fire orbit, implemented the far-fire point orbit plane maneuver on February 15, and implemented the second near-fire brake on February 20. The current equipment is in normal state and various flight controls Work is proceedingly normally.
