HELSINKI — China is preparing to launch its Tianwen-1 Mars orbiter and rover next week with the rollout of the mission’s Long March 5 launch vehicle.
The roughly 878-metric-ton heavy-lift Long March 5 was vertically transferred to its launch area at the coastal Wenchang Satellite Launch Center late Thursday Eastern. 
The rollout indicates that China will launch Tianwen-1, the country’s first independent interplanetary mission, next week.

Final examinations and tests will be conducted before the launch, according to Chinese media. No launch date was announced, instead reports stated liftoff will take place between late July and early August.
Previous Long March 5 launches have seen a six-day period between rollout and launch. This suggests the launch will occur around July 23.
If successful the spacecraft will arrive at Mars in February 2021. The rover, inside an entry vehicle atop the orbiter, will remain attached to the orbiter in Mars orbit for 2-3 months before the landing attempt, a paper published in Nature this week confirms.
“The vertical transport of the rocket to the launching area has shown that we have made good preparations for the launching mission. We will stick to the strict and careful working attitude in the coming days,” Ge Xiaochun, chief engineer at the China National Space Administration, told Chinese media.
“The Mars probe is the first step of China’s planetary exploration project. The coming launching mission has been highly recognized and supported by the international community. We hope to contribute Chinese wisdom, ideas and solutions to the world for peaceful use of the space,” Ge said.
Tianwen-1 orbiter and rover
The Tianwen-1 orbiter carries seven science payloads. It is equipped with a high-resolution camera comparable to HiRise on board NASA’s Mars Reconnaissance Orbiter. It also carries a medium-resolution camera, subsurface radar, mineralogy spectrometer, neutral and energetic particle analyzers and a magnetometer. The orbiter, designed to operate for one Mars year, or 687 Earth days, will also play a relay role for the mission rover.
The roughly 240-kilogram solar-powered rover is nearly twice the mass of China’s ‘Yutu’ lunar rovers. It will carry a ground-penetrating radar, multispectral camera and a Laser Induced Breakdown Spectroscopy instrument. Other payloads will analyze the climate and magnetic environment. The rover will attempt to land in a southern section of Utopia Planitia where it is designed to operate for 90 Mars days.
The Institute for Space Research of the Austrian Academy of Sciences assisted in the development of the orbiter’s magnetometer. The L’Institut de Recherche en Astrophysique et Planétologie under French space agency CNES was involved in the Laser Induced Breakdown Spectroscopy instrument. Additionally, the European Space Agency’s Estrack ground stations will provide support during the early launch phase. Argentina space agency CONAE also has an unspecified role, according to logos present on the payload fairing.

Long March 5
The Long March 5 was delivered on a roughly 30 by 20-meter launch platform, with a 70-meter-tall umbilical tower. Rollout from the assembly building to the launch area took two hours. 
This will be the fourth Long March 5 mission. The second, in July 2017, failed due to an issue with the rocket’s first stage engines. The launcher was subsequently grounded for over 900 days while the issue was being isolated and addressed. The third mission in December 2019 was a high-stakes return-to-flight, success of which cleared the way for the Tianwen-1 launch.
The Long March 5 is part of a new generation of Chinese launch vehicles which use combinations of liquid hydrogen or kerosene fuel with liquid oxygen. These both expand China’s launch capabilities but could also eventually replace the older, hypergolic Long March rockets.
The 5-meter-diameter Long March 5 core stage is powered by two YF-77 hydrolox engines. Each of four 3.35-meter-diameter side boosters are powered by a pair YF-100 kerolox engines.
The Long March 5 is capable of delivering 14 metric tons to geostationary transfer orbit, 8.2 tons to trans-lunar injection, or 6 tons to trans-Mars injection. Tianwen-1 has a mass of around 5 tons.
The fifth Long March 5 is expected to launch the Chang’e-5 lunar sample return late this year. The second launch of the Long March 5B, a variant for LEO launches, will then launch the core module of the Chinese Space Station as soon as early 2021.

Chinese Spacecraft Poised for First Mars Mission
Tianwen-1 will attempt to send an orbiter, lander and rover to the Red Planet, a historically difficult destination

By Ling Xin on July 15, 2020[img=590x0]https://static.scientificamerican.com/sciam/cache/file/A6FAF033-5F01-462F-BB841B3B56FE01A0_source.jpeg?w=590&h=800&86995B81-6309-4608-83B1870134B82297[/img]

With a five-meter-wide, 57-meter-tall rocket waiting to blast off from China’s southern island of Hainan, the nation is quietly making final preparations for its first independent trip to Mars. When the launch window opens in mid-July, Chinese scientists will strive to send a probe to a planet that confused their ancestors with its constantly changing brightness and position in the sky.
The spacecraft, called Tianwen-1, or the “Quest for Heavenly Truth,” will carry 13 scientific instruments to examine the Red Planet from orbit and on its surface. Tianwen-1 will examine how water ice is distributed on Mars, as well as the planet’s physical evolution and its habitability over time. The mission—consisting of an orbiter, lander, and rover—is “the most ambitious thing one could do on a first attempt,” says John Logsdon, a space policy expert at George Washington University.




[*]TROUBLING TRACK RECORD
[*]



[*]The odds of a flawless mission are daunting: Of humanity’s dozens of attempts to orbit or land on Mars to date, only about half have succeeded. After some high-profile setbacks, NASA has deployed five landers, four rovers and multiple orbiters that have brought the world to life for scientists and the public alike. But China’s spacefaring experience beyond Earth orbit has been limited to several robotic moon missions and an orbiter that piggybacked on a failed Russian mission to the Martian moon Phobos in 2011.

Two major risks confront the five-metric-ton Tianwen-1, Logsdon says. First, China’s most powerful heavy-lift rocket, Long March 5, has only launched three times—including a major failure in 2017, when the rocket started to malfunction shortly after takeoff. It took more than two years for scientists to fix Long March 5’s core-stage-engine problem and score a successful flight in late 2019. Its track record makes observers nervous, however.
Second, Tianwen-1’s lander must navigate the challenging Martian atmosphere, which is thick enough to overheat the probe but too thin to decelerate it sufficiently. The spacecraft’s entry, descent and landing technology uses a heat shield, a parachute and a retro-engine to slow its descent, an arrangement resembling that of earlier U.S. missions. Yet when the vessel is just 100 meters above the surface, it will pause, take snapshots of the area and quickly calculate the best landing spot. Then it will shift horizontally to center above that spot and carefully touch down with the lander’s four legs.
In November 2019 China tested this part of the landing procedure, which the nation had previously used successfully in its moon landings, in the province of Hebei. Foreign officials were invited to watch the test on-site. It was the last major public event for Tianwen-1, however. Since then, the China National Space Administration (CNSA) has kept a low profile, and mission scientists have declined or ignored nearly all interview requests.

[*]Should Tianwen-1 land successfully, its research could illuminate new aspects of Mars. For instance, both the orbiter and the rover are equipped with a ground-penetrating radar to chart geologic layers under the surface. The radar on the orbiter can “see” as deep as a few thousand meters, whereas the instrument on the rover has a shallower view but sharp centimeter-level resolution. “China’s main goal [with these radars] is to explore the water-ice layer” under the planet’s surface, says Wlodek Kofman of the Institute for Planetary Sciences and Astrophysics of Grenoble in France.
[*]Tianwen-1’s ability to measure Mars’s magnetic field excites Jim Bell of Arizona State University, principal investigator of the main camera on NASA’s Perseverance rover. One prevailing hypothesis is that the Red Planet used to have a global magnetic field like Earth's, he says. When its smaller molten iron core cooled down, however, Mars gradually lost this shield, exposing the world to solar wind and radiation, thinning its atmosphere and dooming any water that might have flowed on its surface. Since 2014 NASA’s Mars Atmosphere and Volatile Evolution (MAVEN) mission has found ample evidence to support this scenario, but scientists crave a fuller picture. “Tianwen-1 will be very useful in providing more evidence from a different orbit and from the ground,” Bell says. He hopes the Chinese team will share data with the international community piecing together the environmental evolution of Mars.

Tianwen-1 will aim to land in the southern part of Utopia Planitia, a largely flat area between 25 and 30 degrees north of the Martian equator. Geologists have long suspected that this region is covered with ancient mudflows, pointing to stores of bygone water. “It’s an interesting place to investigate potential past subsurface habitability,” says Alfred McEwen, a planetary geologist at the University of Arizona.


[*]The rover’s chance of finding water beneath Mars might be limited by its latitude, McEwen notes. Because it draws its power from solar panels, it must stay near the equator. Today water ice below the planet’s surface, most researchers believe, remains mainly at higher and cooler latitudes.
[*][*]Tianwen-1’s reliance on the sun compelled its team to design hardy instruments, says Rong Shu of the Shanghai Institute of Technical Physics at the Chinese Academy of Sciences. “Since our rover does not have radioisotope power, all the instruments need to endure temperatures as low as –90 degrees Celsius while at rest, and they operate in the temperature range of –40 to –30 degrees C,” he adds.

The rover's payload includes the Martian Surface Component Detector (MarSCoDe), whose design was led by Shu. Similar to ChemCam on NASA’s Curiosity rover, MarSCoDe can fire short laser pulses to vaporize the surfaces of rocks from a few meters away. The instrument will “sniff” the ionized gas produced by these mini blasts and determine the type and quantity of chemical elements in the rocks.
Tianwen-1 is expected to reach Mars in February 2021. It will spend about two months in a parking orbit, waiting for the best timing and surface conditions to land. China’s expanding radio telescope network of tracking and receiving stations will sustain communications between Earth and the probe.

ADVERTISEMENT
Already, Chinese scientists are preparing for more missions in the Tianwen series, including ventures to return rock samples from Mars and an asteroid, to perform a flyby of Jupiter and to explore the margins of the sun’s vast heliosphere. But if Tianwen-1 reaches Mars as planned, Logsdon says, “it will put China in the space exploration business in a big way.”

[Image: 139219481_15949878401561n.jpg]China’s Long March 5 rocket prepares for rollout from an assembly building to its launch pad July 17 at the Wenchang Space Launch Center on Hainan Island. Credit: Xinhua
China’s heaviest rocket has rolled to its launch pad for liftoff Thursday with the country’s first Mars landing mission, an ambitious attempt to place an orbiter around the Red Planet and a robotic rover on the Martian surface in early 2021.
The Chinese mission, named Tianwen 1, is the second of three probes taking aim on the Red Planet this month, when Mars is properly positioned in its orbit around the sun to allow a direct journey from Earth. Such launch opportunities only come about once every 26 months.
A Mars orbiter named Hope developed by the United Arab Emirates in partnership with U.S. scientists successfully launched Sunday aboard a Japanese H-2A rocket. NASA’s Perseverance rover is scheduled for liftoff from Cape Canaveral on an Atlas 5 rocket July 30.
The UAE, Chinese and U.S. missions are all due to arrive at Mars in February 2021.
A Long March 5 rocket is set for liftoff with China’s Tianwen 1 mission some time between 12 a.m. and 3 a.m. EDT (0400-0700 GMT) Thursday, according to public notices warning ships to steer clear of downrange drop zones along the launcher’s flight path.
Chinese officials have not officially publicized the launch date. Chinese state media outlets have only reported the launch is scheduled for late July or early August, and officials have not confirmed whether the launch will be broadcast live on state television.
The launch will be the first operational flight of China’s Long March 5 rocket, the most powerful launch vehicle in the country’s inventory. Ground crews at the Wenchang Space Launch Center on Hainan Island — China’s newest launch site — transferred the Long March 5 rocket to its launching stand Friday for final pre-flight checkouts.
China has launched four Long March 5 rockets since the heavy-lift launcher debuted in 2016. Three of the four missions have been successful, including the last two test flights.
The Long March 5 will aim to send the Tianwen 1 spacecraft away from Earth on a seven-month trip to Mars. The ambitious mission is China’s first probe to another planet, following a series of progressively complex robotic expeditions to the moon.
Most recently, China has landed two rovers on the moon, including the first to explore the surface of the lunar far side. The next Chinese lunar mission, named Chang’e 5, is scheduled for launch late this year on a mission to return samples from the moon.
China kicked off development of the Mars mission in 2016.
It will be the country’s second attempt to reach Mars with a robotic probe, following the Yinghuo 1 orbiter, which was stranded in Earth orbit after launch as a piggyback payload on Russia’s failed Phobos-Grunt mission.

“Benefiting from the engineering heritage of China’s lunar exploration program, the Chinese national strategy set Mars as the next target for planetary exploration,” wrote Wan Weixing, chief scientist of China’s Mars exploration program, in a paper published this month by the science journal Nature Astronomy. “China’s first Mars mission is named Tianwen 1, and aims to complete orbiting, landing and roving in one mission.”
Wan died in May after a long illness.
Chinese officials announced the Tianwen name for the country’s planetary missions in April. The name Tianwen comes from the work of ancient Chinese poet Qu Yuan, meaning “quest for heavenly truth,” according to the China National Space Administration, or CNSA, the country’s space agency.
“The country’s first Martian probe will conduct scientific investigations about the Martian soil, geological structure, environment, atmosphere, as well as water,” CNSA said in a statement.
The entire Tianwen 1 spacecraft weighs about 11,000 pounds, or 5 metric tons, fully fueled for launch, according to the mission summary in Nature Astronomy.
Assuming a successful launch this month, the spacecraft will enter orbit around Mars in February 2021, eventually settling in a loop around the Red Planet ranging between 165 miles (265 kilometers) and nearly 7,500 miles (12,000 kilometers) over the Martian poles.
As soon as next April, the lander and rover modules will detach from the orbiter to begin a descent through the Martian atmosphere. The prime candidate for the Tianwen 1 mission’s landing site is in Utopia Planitia, a broad plain in the northern hemisphere of Mars where radar soundings from orbit have indicated the presence of a reservoir of ice containing as much water as Lake Superior, the largest of the Great Lakes.
The Tianwen 1 rover weighs about 529 pounds, or 240 kilograms, nearly twice the mass of China’s Yutu rovers on the moon.
The orbiter is designed to operate for at least one Martian year, or about two years on Earth. The solar-powered rover, fitted with six wheels for mobility, has a life expectancy of at least 90 days, Chinese officials said.
[Image: tianwen1.jpg]Artist’s illustration of the Tianwen 1 orbiter and rover at Mars. Credit: CNSA / Chinese Academy of Sciences / Nature Astronomy
Chinese scientists say the Tianwen 1 mission will perform a global survey of Mars, measuring soil and rock composition, searching for signs of buried water ice, and studying the Martian magnetosphere and atmosphere. The orbiter and rover will also observe Martian weather and probe Mars’s internal structure.
The orbiter’s seven instruments include a:
  • Medium-Resolution Camera

  • High-Resolution Camera

  • Mars-Orbiting Subsurface Exploration Radar

  • Mars Mineralogy Spectrometer

  • Mars Magnetometer

  • Mars Ion and Neutral Particle Analyzer

  • Mars Energetic Particle Analyzer
The Tianwen 1 rover is cocooned inside a heat shield for a fiery descent to the Martian surface. After releasing from the orbiter mothership, the lander will enter the Red Planet’s atmosphere, deploy a parachute, then fire a braking rocket to slow down for landing.
“Tianwen 1 is going to orbit, land and release a rover all on the very first try, and coordinate observations with an orbiter,” Wan, the late chief scientist for China’s Mars program, wrote in Nature Astronomy. “No planetary missions have ever been implemented in this way. If successful, it would signify a major technical breakthrough.
“Scientifically, Tianwen 1 is the most comprehensive mission to investigate the Martian morphology, geology, mineralogy, space environment, and soil and water-ice distribution.”
The rover’s six science payloads include a:
  • Multispectral Camera

  • Terrain Camera

  • Mars-Rover Subsurface Exploration Radar

  • Mars Surface Composition Detector

  • Mars Magnetic Field Detector

  • Mars Meteorology Monitor
Tianwen 1 is a Chinese-led project, but scientists and support teams from several countries have agreed to provide assistance on the mission.
Scientists from the Institut de Recherche en Astrophysique et Planétologie in France helped develop a Laser-Induced Breakdown Spectroscopy instrument on the Tianwen 1 rover. Scientists from the Space Research Institute at the Austrian Academy of Sciences contributed to the magnetometer on the Tianwen 1 orbiter and helped calibrate the flight instrument.
Argentina is home to a Chinese-owned deep space tracking antenna that will be used to communicate with Tianwen 1 after launch. The European Space Agency has agreed to provide communications time for Tianwen 1 on its own worldwide network of deep space tracking stations.
[Image: 139219481_15949878395221n.jpg]Logos for the European Space Agency, the French space agency CNES, Argentina’s space agency CONAE, and the Austrian Research Promotion Agency (FFG) are installed on the Long March 5’s payload fairing. Credit: Xinhua
When it takes off, ten liquid-fueled engines will power the Long March 5 rocket and Tianwen 1 off the launch pad with nearly 2.4 million pounds of thrust.
The Long March 5’s flight path will take the rocket east from Hainan Island over the South China Sea, where it will drop its four-strap on boosters — each powered by two kerosene-fueled YF-100 engines — around three minutes after liftoff. Unlike launches from China’s inland spaceports, missions originating from Wenchang follow trajectories over the sea, allowing rockets to jettison stages over water rather than over land.
Two YF-77 engines on the Long March 5’s core stage will burn super-cold liquid hydrogen and liquid oxygen propellants for nearly eight minutes. During the first stage burn, the Long March 5 will jettison its clamshell-like payload fairing once the launcher climbs above the thick, lower layers of the atmosphere.
Two restartable hydrogen-fueled YF-75D engines drive the Long March 5’s second stage. The second stage engines are expected to perform two firings before deploying Tianwen 1 on its trajectory toward Mars.

China launches ambitious Tianwen-1 Mars rover mission
By Mike Wall - Space.com Senior Writer 11 hours ago
Tianwen-1 is China's first fully homegrown Mars mission.


[Image: EdllA7rXgAAGrZ4-678x381.jpeg]
China's first fully homegrown Mars mission is on its way to the Red Planet.
The Tianwen-1 mission launched atop a Long March 5 rocket from Hainan Island's Wenchang Satellite Launch Center this morning (July 23) at 12:41 a.m. EDT (0441 GMT).
Tianwen-1 consists of an orbiter and a lander/rover duo, a combination of craft that had never before launched together toward the Red Planet. The ambition of Tianwen-1 is especially striking given that it's China's first stab at a full-on Mars mission. (The nation did launch a Red Planet orbiter called Yinghuo-1 in November 2011, but the spacecraft flew piggyback with Russia's Phobos-Grunt mission. And that launch failed, leaving the probes trapped in Earth orbit.)
"Tianwen-1 is going to orbit, land and release a rover all on the very first try, and coordinate observations with an orbiter," team members wrote in a recent Nature Astronomy paper outlining the mission's main objectives. "No planetary missions have ever been implemented in this way. If successful, it would signify a major technical breakthrough."
Related: Here's what China's Tianwen-1 Mars mission will do

Taking the measure of Mars
If all goes according to plan, Tianwen-1 will arrive at the Red Planet in February 2021. The lander/rover pair will touch down on the Martian surface two to three months later somewhere within Utopia Planitia, a large plain in the planet's Northern Hemisphere that also welcomed NASA's Viking 2 lander in 1976.
The solar-powered rover will then spend about 90 Martian days, or sols, studying its surroundings in detail. (One sol is roughly 40 minutes longer than an Earth day.) It will do so with six different science instruments, which the Nature Astronomy paper identified as the Multispectral Camera, Terrain Camera, Mars-Rover Subsurface Exploration Radar, Mars Surface Composition Detector, Mars Magnetic Field Detector and Mars Meteorology Monitor.
The orbiter will eventually settle into a polar elliptical orbit that takes it as close to the Martian surface as 165 miles (265 kilometers) and as far away as 7,456 miles (12,000 km). The spacecraft will relay information home from the rover and collect science data of its own using seven science instruments: two cameras, the Mars-Orbiting Subsurface Exploration Radar, Mars Mineralogy Spectrometer, Mars Magnetometer, Mars Ion and Neutral Particle Analyzer and Mars Energetic Particle Analyzer.
China's Mars mission includes orbiter, lander and rover

[*]The lander apparently will not do any substantive science work, serving as a delivery system for the rover. That wheeled explorer, by the way, tips the scales at about 530 lbs. (240 kilograms), making it twice as heavy as China's line of moon-exploring Yutu rovers.
Overall, Tianwen-1 aims to take Mars' measure in a variety of ways.
"Specifically, the scientific objectives of Tianwen-1 include: (1) to map the morphology and geological structure, (2) to investigate the surface soil characteristics and water-ice distribution, (3) to analyze the surface material composition, (4) to measure the ionosphere and the characteristics of the Martian climate and environment at the surface, and (5) to perceive the physical fields (electromagnetic, gravitational) and internal structure of Mars," mission team members wrote in the Nature Astronomy paper. 
The paper also explained the mission's name: Tianwen means "questions to heaven," and it was taken from the title of a poem by Qu Yuan, who lived from about 340 to 278 BCE.

Summer of Mars
Tianwen-1 was the second Mars mission to get off the ground in the last four days. 
The United Arab Emirates' Hope orbiter launched on Sunday (July 19) to study the Martian atmosphere and climate, streaking into space from Japan atop an H-2A rocket. Like Tianwen-1, Hope (also known as the Emirates Mars Mission) is historic: It's the first interplanetary mission ever developed by an Arab state. 
And the summer of Mars isn't over yet. NASA's next Mars rover, the 2,300-lb. (1,040 kg) Perseverance, is scheduled to lift off on July 30. 
This clumping of launches is dictated by orbital dynamics; Earth and Mars line up properly for interplanetary missions for just a few weeks once every 26 months. (The European-Russian ExoMars rover was supposed to join the launch party this summer, but it suffered technical issues and now must wait until 2022.)







Tianwen-1 - Origin of China's Mars mission name explained


[*]Perseverance, the centerpiece of the $2.7 billion Mars 2020 mission, will hunt for signs of ancient life inside the 28-mile-wide (45 km) Jezero Crater, which harbored a lake and a river delta billions of years ago. Perseverance will do other work as well, including collecting and caching samples for future return to Earth. Mars 2020 will also demonstrate new technologies, such as the first helicopter to ply alien skies and a device designed to generate oxygen from the carbon dioxide-dominated Martian atmosphere.
All three of these missions are scheduled to arrive at the Red Planet in February 2021. So when the summer of Mars comes to an end, we'll still have a Red Planet winter to look forward to.

Rover has solar panels and not radioactive insides which is what is needed for LONG TERM existence on MARS whether it is Elon Musk or anyone else we cannot live there without NUCLEAR power in some form or another.

ANY rover people carried vehicles CANNOT run efficiently without NUKE energy.

Dust Devils and VAST winds make this a priority.

Astrophysicists investigate the possibility of life below the surface of Mars

Although no life has been detected on the Martian surface, a new study from astrophysicist and research scientist Dimitra Atri at the Center for Space Science at NYU Abu Dhabi finds that conditions below the surface could potentially support it. The subsurface—which is less harsh and has traces of water—has never been explored. According to Atri, the steady bombardment of penetrating galactic cosmic rays (GCRs) might provide the energy needed to catalyze organic activity there.

Atri investigated the biological potential of galactic cosmic-ray-induced, radiation-driven chemical disequilibrium in the Martian subsurface environment; the results are published in the journal Scientific Reports.
There is growing evidence suggesting the presence of an aqueous environment on ancient Mars, raising the question of the possibility of a life-supporting environment. The erosion of the Martian atmosphere resulted in drastic changes in its climate: Surface water disappeared, shrinking habitable spaces on the planet, with only a limited amount of water remaining near the surface in form of brines and water ice deposits. Life, if it ever existed, would have had to adapt to harsh modern conditions, which include low temperatures and surface pressure, and high radiation.
The subsurface of Mars has traces of water in the form of water ice and brines, and undergoes radiation-driven redox chemistry. Using a combination of numerical models, space mission data and studies of deep-cave ecosystems on Earth for his research, Atri proposes mechanisms through which life, if it ever existed on Mars, could survive and be detected with the upcoming ExoMars mission (2022) by the European Space Agency and Roscosmos. He hypothesizes that galactic cosmic radiation, which can penetrate several meters below the surface, will induce chemical reactions that can be used for metabolic energy by extant life, and host organisms using mechanisms seen in similar chemical and radiation environments on Earth.

"It is exciting to contemplate that life could survive in such a harsh environment, as few as two meters below the surface of Mars," said Atri. "When the Rosalind Franklin rover on board the ExoMars mission (ESA and Roscosmos), equipped with a subsurface drill, is launched in 2022, it will be well-suited to detect extant microbial life and hopefully provide some important insights."

China's Mars probe photographs Earth en route to Red Planet

China's first Mars probe has beamed back a photo of the Earth and the Moon as it heads toward its destination, the country's space agency said Tuesday.
The image, which shows the two celestial bodies as small crescents in the empty darkness of space, was taken 1.2 million kilometres (746,000 miles) away from Earth three days after the Tianwen-1 mission was launched on Thursday, the China National Space Administration said.
China joined the United States and United Arab Emirates this month in launching a mission to Mars, taking advantage of a period when Mars and Earth are favourably aligned.
The mission, given a name that means "Questions to Heaven," aims to enter Martian orbit seven months after the launch and release a small rover to study the planet's surface.
It's the latest milestone in Beijing's space programme, which has sent two rovers to the Moon and set up a satellite navigation, Beidou, to rival the United States' GPS.
The National Space Administration on Tuesday said Tianwen-1, which has left Earth's gravitational field, "is currently in good flight conditions, has balanced fuel and is operating normally."
The rover had by Tuesday traveled least 1.5 million kilometres from Earth, the agency said—just a fraction of the 55 million kilometres it must traverse before it reaches Mars.
