After exploring Mars for greater than a 12 months, China’s Tianwen-1 area probe has efficiently taken pictures overlaying your complete Pink Planet, China’s Nationwide Area Administration (CNSA) introduced on June 29.


Tianwen-1, which interprets to “quest for heavenly fact”, consists of six separate spacecraft: an orbiter, two deployable cameras, a lander, a distant digicam, and a Zhurong rover.

The photographs in query have been taken by the orbiter whereas circling Mars 1,344 occasions, capturing pictures of the Pink Planet from each angle whereas Zhurong explored the floor. Within the assertion, CNSA stated the probe has now accomplished all of its duties, which included taking medium-resolution pictures overlaying your complete planet.

Tianwen-1 was launched on July 23, 2020, amidst the turmoil of the COVID-19 international pandemic. What’s distinctive about this mission is China was making an attempt to develop into the primary nation to efficiently ship an orbiter and rover to Mars on the primary attempt. 

Upon profitable orbital insertion and touchdown, Tianwen-1 grew to become a historic victory for each the CNSA and area exploration. Earlier than Tianwen-1, the one two profitable missions to ship each an orbiter and lander to Mars have been NASA’s Viking 1 and a pair of missions in 1975.

Previous to that, the Soviet Union had tried this feat with their Mars 2 and three missions in 1971, and Mars 6 in 1973. Mars 2 was an outright failure with the lander being destroyed and the orbiter sending again no information. On Mars 3, the orbiter obtained roughly eight months of information and whereas the lander touched down safely, it solely returned 20 seconds of information. On Mars 6, the orbiter produced information from an occultation experiment, however the lander failed on descent.

Throughout its time exploring the Pink Planet, Tianwen-1 confirmed a Mars we have come to each love and admire: dusty dunes, protect volcanoes, influence craters, and even the north pole.

Whereas the orbiter was taking these superb pictures, Zhurong was gathering information and details about Mars’ geological construction, environment, atmosphere, and soil.

Total, the probe has collected 1,040 gigabytes of uncooked scientific information, which the CNSA stated has been processed by scientists again on Earth and handed over to researchers for additional research.

Whereas the probe entered Mars’ orbit on 10 February 2021, the Zhurong rover did not contact down on Mars till Could 14 of that very same 12 months. It landed in Utopia Planitia, present residence of NASA’s Viking 2 spacecraft which landed within the huge Martian plain in 1975.

In June 2022, Zhurong efficiently discovered hydrated minerals in sediment relationship to Mars’ most up-to-date geologic interval that are possible related to groundwater. Hydrated minerals embody substances comparable to olivine, pyroxene, and feldspar that have been possible altered as they built-in water into their chemical buildings.

Sadly, Zhurong needed to enter its dormant mode beginning on 18 Could 2022, on account of dropping temperatures through the Martian winter, together with poor sand and dirt situations. This dormant mode ensures the long-term survivability of the rover, which is able to reawaken someday in December.

Whereas Tianwen-1 makes China solely the third nation to efficiently land a spacecraft on the floor of Mars, the European Area Company (ESA), India, and the United Arab Emirates have efficiently despatched their respective spacecraft to orbit the Pink Planet.


Tianwen-1 additionally demonstrates China’s robust aspiration to discover Mars, because it not too long ago introduced plans to return Mars samples to Earth in 2031, a full two years sooner than NASA and the ESA.

Together with their formidable robotic missions, the CNSA introduced final 12 months that they plan to ship its first crewed mission to the Pink Planet in 2033 with a aim to ship common missions to Mars and ultimately construct a base there. This 2033 timeframe is in stark distinction to NASA, who introduced earlier this 12 months that they plan to launch astronauts to Mars within the late 2030s or early 2040s.

China appears very severe about human area exploration, as their Tiangong area station at the moment homes three astronauts on six-months stays, with the most up-to-date crew arriving simply final month.

The place will area exploration take us within the coming years? Which nation will land the primary people on Mars? Solely time will inform, and this is the reason we science!
