BEIJING — China's Mars rover and orbiter have suspended explorations since mid-September, to wait out a period of sun outage, the China National Space Administration said on Oct 4.

A sun outage refers to a phenomenon when Mars and the Earth move to either side of the sun and the three are almost perfectly aligned. During this period, the solar electromagnetic radiation will increase and disrupt the communications between the probes and the Earth.

The sun outage will end in mid-October, and the two probes will resume communications with the Earth and continue scientific explorations on the red planet, said the administration.

China's Tianwen-1 mission, comprised of an orbiter, lander and rover, was launched on July 23, 2020. The rover Zhurong drove down from its landing platform to the Martian surface on May 22.
