BEIJING, Aug. 20 (Xinhua) -- China's Mars probe Tianwen-1 has traveled more than 8 million km away from Earth and is functioning normally, according to the Lunar Exploration and Space Program Center of the China National Space Administration Thursday.

As of 11:20 p.m. Wednesday, the Mars probe has traveled 8.23 million km away from Earth. Starting from 10:20 p.m. Wednesday, multiple payloads on the Mars probe, including Mars Magnetometer, Mars Mineralogy Spectrometer and High-resolution Camera, have completed self-check to confirm that they are in normal condition.

Medium and high-resolution cameras will be used for imaging the Mars surface and conducting research on the topography and geological structure of the planet's surface. The Magnetometer will detect the magnetic environment on Mars, and the Mineralogy Spectrometer will be used to analyze the composition and distribution of minerals on Mars.

China launched the Mars probe on July 23, designed to complete orbiting, landing and roving in a single mission, thus taking the first step in its planetary exploration of the solar system.

The Mars probe is expected to reach the red planet around February 2021. After entering the orbit, it will spend another two to three months surveying the candidate landing sites before landing.
