    China's Tianwen 1 Mars probe had traveled 300 million kilometers as of Tuesday morning, according to the China National Space Administration. The administration said in a statement that the spacecraft1 was in good condition.

    By Tuesday morning, the robotic probe had flown 116 days in an Earth-Mars transfer trajectory2 toward the red planet, about 63.8 million km away from the Earth, it noted3.

    截至11月17日,“天问一号”已在地火转移轨道上飞行了116天,距离地球约6380万千米,仍在奔向火星的途中。

    The spacecraft is programmed to reach the Martian gravitational field in February and then begin to prepare for landing, which is expected to take place in May.

    “天问一号”计划于2021年2月到达火星引力势场,开始做降落的相关准备,预计2021年5月着陆火星表面。

    After the landing, it will release a rover to conduct scientific exploration.
