    "China's Tianwen-1 probe performs orbital adjustment around Mars"

    http://www.xinhuanet.com/english/202..._139744513.htm

    China's Tianwen-1 probe on Monday performed an orbital maneuver around Mars after it became the country's first spacecraft to explore an extraterrestrial planet.

    A 3000N engine was ignited at 5 p.m. (Beijing time) to ensure the probe's trajectory passes the poles of Mars. The periareion, the point in the orbit that is closest to Mars, was adjusted to 265 km, according to the China National Space Administration (CNSA).

    The spacecraft will perform several more orbital adjustments to enter a parking orbit, said the CNSA.

    "China Mars Orbiter/Lander/Rover – Ready for Red Planet Probing"

    https://www.leonarddavid.com/china-m...lanet-probing/

    Now circuiting Mars, China’s Tianwen-1 spacecraft is slated to perform systematic checks of onboard equipment. The craft used its 3000 newton engine on February 15 to place it into a polar orbit around the Red Planet.

    Tipping the scales at 5 metric tons, Tianwen-1 – consisting of an orbiter, lander, and rover — will perform several more orbital adjustments before placing itself into a parking orbit from which the orbiter will perform an initial survey of candidate landing areas.

    "Tianwen 1 probe enters preset parking orbit"

    http://www.chinadaily.com.cn/a/20210...d0baaa9f0.html

    China's Tianwen 1 robotic probe entered its preset parking orbit above Mars on Wednesday and will fly in this orbit for about three months before releasing its landing capsule, said the China National Space Administration.

    The spacecraft, which has entered a crucial stage in China's first interplanetary exploration mission after seven months of lengthy space voyage, conducted its third near-Mars deceleration maneuver at 6:29 am and then moved into an orbit with a perigee of about 280 kilometers, the administration said in a brief statement.

    "Three candidate names for China's Mars rover come out after global poll"

    http://www.chinadaily.com.cn/a/20210...d0baac2d4.html

    Three possible names for China's first Mars rover have come out after a 40-day global online poll.

    "Zhurong," a fire god in ancient Chinese mythology, tops the list while "Nezha," a beloved Chinese mythological figure, and "Hongyi," which means having a broad and strong mind in Chinese, ranked second and third, respectively.

    The China National Space Administration in January unveiled a list of 10 selections for the name after a global naming campaign that kicked off in late July 2020. Netizens at home and abroad were invited to vote on 10 candidates from Jan 20 to Feb 28.

    Starting Tuesday, a panel of experts will also vote for the final candidates. The administration will decide the top three names based on public voting and expert opinions.

    Same LM-5 Chang Zheng 5 rocket as Tianwen 1 is going to launch to Neptune? https://spacenews.com/china-to-launc...-solar-system/ 'The project somewhat echoes NASA’s Voyager missions'. The Chinese-Russia Moon plan? There is currently “no ESA stance” on the China-Russia International Lunar Research Station. https://spacenews.com/esa-cnsa-heads...e-space-plans/ 'Zhang stated that both China and Russia want the ILRS to be open to cooperation from all nations, including ESA.'

    As I understand Asian countries in the East they have this Good and bad luck legend thing about dates and names, while they are modern countries that have a lot of technology and follow science, they inside these modern groups still do have their numerology and superstitions. I done silly stuff that triggers superstitions without know it, seen it myself drank a beer down and then sticking chopsticks vertical in a bowl of rice. Do this and you will be surrounded by shocked looks on their faces like they are watching a horror movie, because it reminds them of their gravestones or funeral service. It's like how some parts of the West had this thing about black cats even today it takes four to six days longer for black shelter cats to get a home or people have this '13' thing, its unlucky even though the crew of Apollo 13 returned safely home. S.Korea, Japan and China are notorious for naming stuff while keeping in mind old traditions, the Japanese Kaguya and Hayabusa were named after launch, its probably a tradition that will continue for some time.

    "Zhurong on course for historic journey"

    https://www.marsdaily.com/reports/Zh...urney_999.html

    If it touches down safely on the red planet and works as planned, the Tianwen 1 rover will be the sixth such vehicle deployed on Mars, following five predecessors launched by the United States.

    If the semi-autonomous craft functions efficiently, it will work for at least three months and undertake comprehensive surveys of the planet.

    The rover, recently named Zhurong after an ancient god of fire, is 1.85 meters high and weighs about 240 kilograms.

    "Tianwen-1 ready for Mars touchdown amid high confidence as landing window opens"

    https://www.globaltimes.cn/page/202105/1223485.shtml

    In the wake of China's successful launch of the Tianhe core cabin, the first section for the country's first space station, into planned orbit, stargazers from all over the world have now turned their heads once again to Mars, looking forward to the event of China's Tianwen-1 probe's upcoming landing somewhere in the southern part of a vast plain known as Utopia Planitia on the Red Planet.

    Aiming to achieve “orbiting, landing and roving” all in one mission, China's Tianwen-1 probe, which managed to smoothly reach Martian parking orbit in February, has entered crucial touchdown stage. The probe will land on the Red Planet at a selected time between early Saturday morning and Wednesday, the China National Space Administration (CNSA) announced on Friday afternoon.

    A lot of social media buzz on places like twitter. There are rumors on social media it has landed. It will have already entered the Martian atmosphere.
    You have the 'SevenMinutesOfTerror' passed, then communication with the Chinese Orbiter and then travel time between Mars and Earth for the signal.
    I guess we'll see if everything is in one piece when the Chinese State media finally releases some official statement.
    A social media account called 'SKLPlanets-Macau' says Landing point: 109.7 E, 25.1 N, less than 40 km from target location in Utopia Planitia.
    A number of amateur radio guys seem to have posted messages where they claim to have tracked the signal. It's all together in one piece and landing nominal? Nothing from Xinhua, CCTV / CGTN or HK media or Macau media. Emily Lakdawalla Planetary Society posted links to people she considers to have reliable info.

    A Chinese blogging website with a Peoples-Daily news account said the Chinese Rover would try to land on Mars' Utopian plains.

    Congratulations China Orbiting and landing on Mars on your first try

    "China's Zhurong rover makes history with Mars landing"

    https://www.channelnewsasia.com/news...space-14813910

    China's Zhurong rover touched down on Mars early on Saturday (May 15), state media reported, a triumph for Beijing's increasingly bold space ambitions and a history-making feat for a nation on its first-ever Martian mission.

    The lander carrying Zhurong completed the treacherous descent through the Martian atmosphere using a parachute to navigate the "seven minutes of terror" as it is known, aiming for a vast northern lava plain known as the Utopia Planitia.

    The mission "successfully landed in the pre-selected area", state broadcaster CCTV said, while the official Xinhua news agency cited the China National Space Administration in confirming the touchdown.

    It makes China the first country to carry out an orbiting, landing and roving operation during its first mission to Mars - a feat unmatched by the only other two nations to reach the Red Planet, the US and Russia.

    Good for them. Though actually the USSR was the first to land on Mars, but it was only just a barely successful landing. Mars 3 landed in 1971, and sent a signal back for about two minutes and stopped, never to be heard from again. Probably a hard landing. Mars 2 just crashed.

    China lands its Zhurong rover on Mars. BBC coverage of the landing

    China has successfully landed a spacecraft on Mars, state media announced early on Saturday.

    The six-wheeled Zhurong robot was targeting Utopia Planitia, a vast terrain in the planet's northern hemisphere.

    The vehicle used a combination of a protective capsule, a parachute and a rocket platform to make the descent.

    The successful touchdown is a remarkable achievement, given the difficult nature of the task.

    Only the Americans have really mastered landing on Mars until now. All other countries that have tried have either crashed or lost contact soon after reaching the surface.

    Chinese President Xi Jinping congratulated the mission team's "outstanding achievement" in a special message.
    "You were brave enough for the challenge, pursued excellence and placed our country in the advanced ranks of planetary exploration," he said.

    The robot officially landed at 07:18 on Saturday, Beijing time (Friday 23:18 GMT), according to state media.

    It took 17 minutes to unfold its solar panels and send a signal back to Earth.

    What is China’s Tianwen-1 Mars mission?
    https://www.scmp.com/news/china/scie...1-mars-mission

    Spacecraft to Mars, consisting of an orbiter, deployable camera, lander and the Zhurong rover. A few days after landing, the lander is designed to deploy the rover Zhurong, which is designed to explore the surface for 90 sols.

    Must article - Macau University of Science and Technology
    https://www.must.edu.mo/en/news/33991-article07232155-e
    "Tianwen-1" carries 13 scientific payloads that will help reach the main scientific goals, which include: (1) Study the morphology and geological structure of Mars. This will be achieved by detection of the global topographic features, obtaining high-precision morphological data of typical areas, and carry out research on the genesis and evolution of Martian geological structures; (2) Research on the surface soil characteristics and water ice distribution on Mars. This will be accomplished by identification of Martian soil types, weathering and deposition characteristics and its global distribution, search for the presence of water ice, and researching the layered structure of Martian soil profiles; (3) Research on the composition of Mars surface material. This will be performed by surface mineral composition analysis to determine the rock types and the secondary minerals that are present on the surface of Mars; (4) Study the environmental characteristics of Mars, including the ionosphere and surface climate. This will be achieved by researching the ionospheric structure in the Martian space environment, measuring the surface temperatures, pressures, and wind fields of Mars to track seasonal changes in surface weather; (5) Research the early geological evolution, present day magnetic and gravitational fields, and the internal structure of Mars. This will be accomplished through studying the characteristics of the Martian magnetic fields and researching the internal mass distribution and gravity fields of Mars.
