China’s Tianwen 1 orbiter and Zhurong rover are as soon as once more lively at Mars following a communications blackout attributable to the sun interfering with radio indicators despatched from Earth.
Tianwen 1 and Zhurong had been in standby mode for a couple of month, since mid-September. With the Earth and Mars orbiting at reverse sides of the sun and all three our bodies nearly completely aligned, communications with the Red Planet had been successfully blocked by interference from our star’s charged particles.
The China Lunar Exploration announced (Chinese) on Thursday (Oct. 21) that the orbiter and rover had reestablished communications and resumed science and exploration actions.

Both Tianwen 1 and Zhurong are lively ahead of first anticipated, because the spacecraft had been anticipated to be past the attain of communications till the tip of October. This estimate was seemingly conservative as this was the primary time China has operated Mars spacecraft throughout a once-every-26-month solar conjunction. (Tianwen 1 is China’s first Red Planet mission.)
Zhurong had lined a total of three,878 ft (1,182 meters) earlier than occurring standby for the solar conjunction, Sun Zezhou, Tianwen 1 chief designer with the China Academy of Space Technology (CAST), told Chinese media earlier this month. Zhurong landed in Utopia Planitia on May 14 and rolled onto the floor per week later, having remained in orbit since February after Tianwen 1 arrived at Mars.
Zhurong additionally returned a panoramic view of its environment forward of occurring standby, displaying the world will probably be exploring.
Things will likely be altering for each Tianwen 1 and Zhurong within the coming weeks. In early November, the orbiter will finish its function as a devoted relay satellite for Zhurong, because the rover has completed its primary mission. Tianwen 1 has been passing over Zhurong’s place as soon as each Martian day, or sol, to relay information from the rover to Earth, however it would now shift its orbit to start international mapping and evaluation of the Martian floor and subsurface with its suite of seven science devices.
While Tianwen 1 will nonetheless present relay providers, a European satellite might additionally step in to assist transmit Zhurong’s information throughout lots of of thousands and thousands of miles of space. The European Space Agency’s (ESA) Mars Express, which launched in 2003, is planning to carry out a set of 5 checks with Zhurong in November.
Mars Express will try to obtain information from Zhurong after which retransmit the knowledge to Earth, James Godfrey, Mars Express spacecraft operations supervisor at ESA, informed Space.com. However, Mars Express will not be capable to ship instructions to Zhurong, because the rover’s message-sending capabilities are restricted to channels that Mars Express cannot monitor.
In the meantime, Zhurong will proceed its journey south from the touchdown platform that safely delivered it to the floor.
A brand new paper printed in Earth and Planetary Science Letters on geomorphologic exploration targets led by Ye Binlong of the University of Hong Kong) and Qian Yuqi of the China University of Geosciences identifies fascinating targets for evaluation by Zhurong. These embody mud volcanoes and options that will have been fashioned by actions of subsurface water and ice.
Zhurong’s ground-penetrating radar is anticipated to supply “fundamentally new perspectives” on potential subsurface Martian water ice, the authors declare. Underground water wouldn’t solely have implications for potential life, however would even be a strategic pure useful resource for future crewed Mars exploration. NASA’s Perseverance rover can be searching for water reserves underneath the Martian floor utilizing its personal ground-penetrating radar.
A preprint science paper about Zhurong’s progress to date reveals that the rover has been overlaying overlaying on common about 33 ft (10 meters) and as much as 66 ft (20 meters) per sol for the primary 60 sols, relying on terrain and science duties, additionally detailing the route planning and autonomous drive elements of Zhurong’s operations.
The paper additionally reveals among the options within the touchdown space and rocks displaying proof of being weathered. Expect Zhurong to proceed returning new pictures, findings and science information because it makes fast progress south.
