2021年2月10日19时52分，中国首次火星探测任务天问一号探测器实施近火捕获制动，环绕器3000N轨控发动机点火工作约15分钟，探测器顺利进入近火点高度约400千米、周期约10个地球日、倾角约10º的大椭圆环火轨道，成为我国第一颗人造火星卫星，实现“绕、着、巡”第一步“绕”的目标，环绕火星获得成功。

首次火星探测任务由地火转移阶段进入火星捕获阶段后，天问一号环绕器携带的中分辨率相机、高分辨率相机、磁强计、矿物光谱分析仪、离子与中性粒子和能量粒子探测仪等载荷将陆续开始工作，对火星开展多维度探测。

自2020年7月23日成功发射以来，天问一号探测器已累计飞行202天，完成1次深空机动和4次中途修正，抵达火星时飞行里程约4.75亿千米，距离地球约1.92亿千米，器地通信单向时延约10.7分钟，各系统状态良好。后续天问一号还将经过多次轨道调整，进入火星停泊轨道，开展预选着陆区探测，计划于2021年5月至6月择机实施火星着陆，开展巡视探测。

China's first Mars probe Tianwen-1 has successfully entered the orbit of the red planet after a crucial "brake" to decelerate and be captured by Mars gravity, according to China National Space Administration.

The administration said that the probe's systems are in good condition and will later shift orbits and begin to detect the preliminary landing areas.

It's scheduled to make a landing on the red planet when the chance comes, around May and June, to begin scientific surveys.

Tianwen-1 was launched by a Long March 5 heavy-lift carrier rocket on July 23. It has flown for 202 days and covered nearly 470 million kilometers on its journey to Mars.

During the time, it conducted a deep-space orbital maneuver and four mid-course corrections to make sure it heads in the right direction to Mars.
