天问一号传回首幅火星照片
Tianwen-1 sends back its first photo of Mars
The reporter learned from the China National Space Administration (CNSA) that at 20:00 BJT on February 5, China's first Martian probe Tianwen-1 had completed its fourth orbital midway correction to ensure Mars capture as planned.
Up to now, Tianwen-1 has been in orbit for about 197 days, 184 million kilometers away from the Earth, 1.1 million kilometers away from Mars, with a flying distance of 465 million kilometers. The spacecraft's systems are in good condition. Earlier, Tianwen-1 acquired its first image of Mars at a distance of about 2.2 million kilometers. (Yang Lu)

China’s Tianwen-1 probe beams back 1st PHOTO of Mars during historic mission
5 Feb, 2021 16:32
The space race is heating up once again after China’s Tianwen-1 Mars probe beamed back its first image of Mars amid the country’s historic first trip to the Red Planet.
The image arrived some six months after the craft blasted off from China’s southern Hainan island in July 2020.
The black-and-white picture was taken around 2.2 million kilometers (1.4 million miles) from Mars or around 184 million kilometers from Earth some 197 days into its mission, according to the China National Space Administration (CNSA). [So far the probe has a flying distance of about 465 million kilometers.]
The unmanned Tianwen-1 is expected to enter Mars’ orbit later this month and will attempt a landing on the Red Planet’s Utopia Planitia in its northern hemisphere in May, where it will deploy a rover.
This rover is currently pencilled in to conduct a 90-day survey mission in what would be another historic first for the mission and for the world, as it would mark the first time in history a country managed to orbit, land and deploy an exploratory rover in its inaugural mission to the Red Planet.

China readies Asia’s largest reflector antenna to receive data from its first Mars mission (2021-02-04)
China's 70-meter-wide steerable reflector antenna has completed its operational checks and is ready to receive signals from the country's Tianwen-1 mission, which is expected to enter the orbit of Mars next week.
The construction of the massive radio telescope to service the maiden voyage of China’s mission to Mars began in 2018 in the country’s northern region of Tianjin. It was finished just in time for the spacecraft's approach to the Red Planet.
The new dish antenna, which was put in service on Thursday (February 4th), is composed of 1,328 high-precision panels covering an area equal to ten basketball courts, according to local media reports.
Its dish has a diameter of 70 meters – unparalleled in Asia – though it's still 30 meters smaller than the world's largest steerable antenna at the Green Bank Radio Telescope in the American state of West Virginia.
China had been using three antennas with diameters of 35 to 50 meters in Beijing and Kunming. But they weren't strong enough to assure quality reception of data from Mars, currently more than 180 million kilometers away from Earth.
The Martian orbit takes it as far as 400 million kilometers away from Earth when the two planets swing to opposite sides of the sun from each other. Crucially for the project, China can now link all four of the country's telescopes to maximise their capabilities.
Tianwen-1, which was launched in July 2020, is scheduled to reach the gravitation field of Mars and perform breaking maneuvers on February 10, one day before the eve of the Chinese New Year.
The ambitious project by the China National Space Administration (CNSA) aims to deploy a Mars orbiter and rover on its surface. If the landing of the vehicle is a success, China will become the second country to successfully operate a rover on Mars after the US.
The Chinese scientists plan to use the Tianwen-1 mission to search for evidence of past and current life on the planet, explore its soil and atmosphere, characterize water distribution and draw maps of the Martian surface, among other things.

From stromgade @stromgade on 2021.02.06:
TJS-6 image from Chinese TV confirming it is indeed a missile warning satellite:
It is identical to TJS-2 and TJS-5, it has cameras with a very optical field with a large diameter and a very wide field given the angle of the speakers.
In other thread, someone posted a question to the OP:
Question: "If I understand correctly, you need 4 satellites in GEO and 2 in HEO for global coverage. Why both in HEO?" (HEO = highly elliptical orbit)
Answer: "To cover the North Pole, we cannot see the North Pole from the GEO orbit."

Why will it take 3 months for it to attempt a landing on Mars after getting to Mars? Why so long?
From what I know, the American and Japanese mars probe that launched about the same time will be landing before May. Any reason about this ?

Good name.胡锡进

中国宣布4日在本国境内成功进行了一次陆基中段反导拦截技术试验。老胡认为这次试验来得非常及时，彩！
Hu Xijin on Weibo (2021-02-04):
China announced that it has successfully conducted a ground-based mid-course anti-missile interception technology test in its territory on Thursday. Lao Hu thought the experiment could not have come at a better time.
Admiral Charles A. Richard, head of the US Strategic Command (STRATCOM), on Tuesday (02 Feb) urged the US to rethink its approach to deterring China and Russia, including considering the "realistic possibility" of nuclear war. To put it simply, he is asking the US to carry out nuclear blackmail against China and Russia, using "nuclear war" to deter China and Russia, especially to intimidate China.
Lao Hu is willing to regard China's successful test as a strong response to the arrogant clamour of the above-mentioned US commander, although China has said in the statement that the test is "not aimed at any country".

NOTE:
To certain PDF Mods,
Be BRAVE and be Logical and STOP being a SLAVE of You--Know--Who.
STOP blocking n deleting my posts.
Yes, Great question.
The reason for 3 months waiting time for TIANWEN-1 is to
completely survey Mars surface, and to find the most Optimum
and the Best Landing point for the TW1 Rover given the
EXTRA fuel available because the PRC CHN * Solar Tech + Battery Tech
are performing way more efficient in Cold Space environment.
Thus, basically use 1 step to defeat the Vxrmxn
Undisputed Snakes 2 steps.

@Han Patriot ,,
Again as usual, your LAME answer indicate such

Way too many mainland Chinese are way too ( ”跪霉” + ”崇霉” )
worshiping as in ... a SLAVE worshiping its MASTER,
to the point of extremely embarrassing to all other normal ASIAN.
No wonder, because of this
( ”跪霉” + ”崇霉” ) worshiping as in ... a SLAVE worshiping its MASTER
way too many PDF mainland Chinese selfishly FAIL to support other posters
and my posts where we always defend PRC CHN.

Chill numb nuts, it's a fact only US landed so far, I was correcting him that Japan did not land.

China urged to create biggest radar system to save Earth from asteroid strike
Chinese scientists and military researchers outline plan for several radio dishes as ‘responsibility to mankind’.
China has several large telescopes in coastal areas, such as the 65 Tianma telescope in Shanghai, but Li and colleagues said local residents might protest against running such a facility in densely populated areas.
Developed areas also had more air traffic and communication networks were susceptible to interference when the radar was on, they said.
Another candidate site considered by researchers is the FAST telescope in Pingtan, Guizhou. It has a 500-metre-wide radio dish, the largest in the world. But upgrading Fast to a planetary radar had many technical challenges, according to Li.
These issues made Xinjiang the most promising candidate site. The autonomous region in western China has low population density – among the lowest in the country.
Several advanced antenna arrays are already up and running there. In Qitai, a county less than 200km (125 miles) from Urumqi in Xinjiang, a 110-METRE STEERABLE TELESCOPE – nearly 60 PER CENT WIDER than Goldstone – is under construction and expected to be finished by 2023.
The planetary radar can also monitor other targets such as space debris. It will be a DUAL-USE FACILITY serving both military and civilian purposes. The design, construction and operation will be led by the Chinese military with collaboration from civil institutes such as the National Astronomical Observatories under the Chinese Academy of Sciences, according to a Beijing-based astronomer informed about the project.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Hahaha, I have never read about the Qitai giant telescope...even much bigger than the US' largest one in Goldstone, and suddenly popped up an article saying the need for a planetary radar to track asteroid... yet China has been half-way building one
sounds like an explanation is given afterwards. 
And I am still trying to fathom the size of the telescope having DISH diameter of 110 meters... and steerable...
