天问一号飞運騎遊達达3亿 ….As of 17th  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 ……. 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………

 The medium-resolution camera, high-resolution camera, and spectrometer in the payload will pre-select the topography and landforms of the low-latitude landing area such as the southern Utopia Plain. , Sand and dust weather, etc. to conduct detailed investigations to assess the feasibility of the Martian environment and landing timing……

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…..

 

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.
