The China National Space Administration (CNSA) released the image Feb. 5, demonstrating that the powerful, high-resolution camera on the Tianwen-1 spacecraft is working properly.
The greyscale image was captured at a distance of 1.36 million miles (2.2 million kilometers) from Mars, according to CNSA.

Within 148 pages, explore the mysteries of Mars. With the latest generation of rovers, landers and orbiters heading to the Red Planet, we're discovering even more of this world's secrets than ever before. Find out about its landscape and formation, discover the truth about water on Mars and the search for life, and explore the possibility that the fourth rock from the sun may one day be our next home.
A labeled version of the image indicates the location of notable features on display, namely Acidalia Planitia (1), Chryse Planitia (2), Meridiani Planum (3), Schiaparelli Crater (4) and Valles Marineris (5).
Tianwen-1, a combined orbiter and rover, has since closed in on the Red Planet and was 683,000 miles (1.1 million km) away on Friday. The spacecraft is expected to enter Mars orbit on Wednesday (Feb. 10). The five-ton spacecraft will burn of its engines to slow the vehicle down enough to be captured by Mars' gravitational pull.
CNSA also stated that Tianwen-1 completed a fourth trajectory correction maneuver Feb. 5 at 7 a.m. EST (1200 GMT, 8 p.m. Beijing time) to ensure the spacecraft is on course for entering Mars orbit.
The spacecraft has traveled 289 million miles (465 million km) during its 197 days in space and was about 114 million miles (184 million km) from Earth at the time of the trajectory correction maneuver. All of the spacecraft's systems are in good working condition, CNSA said.
The great distance between Earth and Tianwen-1 means a communications delay of around 10 minutes. This means the spacecraft will need to carry out commands to start the braking burn by itself, with instructions sent in advance from the Beijing Aerospace Control Center.
After entering orbit, Tianwen-1 will begin to prepare for a landing attempt of the mission's rover. The orbiter will begin imaging the main candidate landing site within the huge impact basin Utopia Planitia, to the south of NASA's Viking 2 landing site, ready for a landing attempt around May.
If the roughly 530-lb. (240 kilograms) solar-powered rover lands safely, it will investigate the surface soil characteristics and potential water-ice distribution with its Subsurface Exploration Radar instrument. The rover also carries panoramic and multispectral cameras and instruments to analyze the composition of rocks.
Meanwhile, the Tianwen-1 orbiter will study the Red Planet's surface with medium- and high-resolution cameras and a sounding radar, and make other detections with a magnetometer and particle detectors.
Tianwen-1 launched in July and will arrive at Mars a day after the United Arab Emirates' Hope mission and a week before NASA's Perseverance rover.
