BEIJING, Feb. 5, 2021 -- Photo released by the China National Space Administration CNSA shows the first image of Mars captured by Mars probe Tianwen-1 from a distance of 2.2 million km. China's Mars probe Tianwen-1 conducted its fourth orbital correction Friday night, according to the CNSA.    The probe carried out the orbital correction at 8 p.m. Beijing time, aiming to ensure that the probe achieves a sound planned rendezvous with Mars.    The CNSA also said the probe had captured the first image of Mars from a distance of 2.2 million km.    The probe has traveled about 197 days in orbit, flying about 465 million km. It is currently 184 million km from Earth and 1.1 million km from Mars. All probe systems are in good working condition, the CNSA said. (Photo by Xinhua via Getty) (Xinhua/Xinhua via Getty Images)

国家航天局日前宣布,我国首次火星探测任务「天问一号」探测器已顺利完成地火转移段第四次轨道中途修正,以确保按计划实施火星捕获。「天问一号」在距离火星约 220 万公里处拍摄到的火星图像也已经顺利传回,这是中国的首幅火星图像,标志着中国航天史上的又一座里程碑。截止到目前,天问一号已在轨飞行约 200 天,距离地球约 1.84 亿公里,距离火星约 110 万公里,飞行里程已达到约 4.65 亿公里,探测器各系统现在都状态良好。

从航天局给出的对比图中可以看到,包括阿茜达利亚平原、克律塞平原、子午高原、斯基亚帕雷利坑,以及最长的峡谷 — 水手谷等火星标志性地貌在图像中都清晰可见。如果不出意外的话,「天问一号」将于 2 月 10 日进入火星轨道,探测车则会在五月着陆乌托邦平原。实际上,早在 2011 年时,我国就曾希望借俄罗斯火箭之力将自己打造的首颗火星探测器「萤火一号」送往火星。但因为火箭芯片的设计问题,最终该任务并没有成功。十年之后,中国自己的航天技术已经有了长足的进步,天问一号如果能顺利完成此行,对我国接下来的航太发展应该能起到很大的激励作用吧。
