As of Friday morning, the Tianwen-2 probe had been operating smoothly in orbit for over eight days, reaching a distance of more than 3 million kilometers from Earth, according to the China National Space Administration (CNSA) Friday.

中国国家航天局在周五早上表示，截至当天上午，天问二号探测器已在轨平稳运行逾8天，距地球超过300万公里。

The CNSA also released an image captured by the probe, showing one unfolded solar panel.

该局同时公布了探测器拍摄的太阳翼展开实拍图像。

China launched its first asteroid sample-return mission, Tianwen-2, on May 29, an endeavour to shed light on the formation and evolution of asteroids and the early solar system.

我国于5月29日发射首个行星采样返回任务“天问二号”，旨在揭示小行星及太阳系早期的形成演化机制。

The Tianwen-2 mission aims to achieve multiple goals over a decade-long expedition: collecting samples from the near-Earth asteroid 2016HO3 and exploring the main-belt comet 311P, which is more distant than Mars.

本次任务计划通过为期十年的深空探测实现多个目标：采集近地小行星2016HO3的样本，并探索比火星更遥远的主带彗星311P。

To meet the power demands during the deep-space voyage, the Tianwen-2 probe is equipped with circular, flexible solar panels.  

为满足深空航行中的能源需求，天问二号探测器配备了圆形柔性太阳翼。
