Mars probe marks first step '天问一号'首次轨道修正
China's Mars probe Tianwen-1 successfully carried out its first orbital correction Sunday morning, according to the China National Space Administration (CNSA).
The probe conducted the orbital correction at 7 am (Beijing Time) after its 3,000 N engine worked for 20 seconds, and continued to head for Mars.
Before the orbital correction, the Mars probe had traveled more than 230 hours in space, and was about 3 million km away from the Earth. All the systems of the probe were in good condition.
The probe will undergo several orbital corrections in a more than six-month journey to Mars, said the CNSA source.
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.
