>Mars probe marks first step'天問一號'首次軌道修正China's Mars probe Tianwen-1 successfully carried out its first orbital correction Sunday morning, according to the China National Space Administration (CNSA). 據國家航天局消息，北京時間8月2日，中國火星探測器"天問一號"成功實施了首次軌道修正。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. 當日早7時，"天問一號"3000牛發動機工作20秒完成了軌道修正，並繼續飛向火星。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.此次軌道修正前，"天問一號"已在太空中飛行逾230個小時，距地球約300萬公裡，所有系統均狀態良好。The probe will undergo several orbital corrections in a more than six-month journey to Mars, said the CNSA source. 國家航天局表示，在6個多月前往火星的旅途中，"天問一號"將進行多次軌道修正。The Mars probe is expected to reach the red planet around February 2021. 預計"天問一號"火星探測器將在2021年2月前後到達火星。After entering the orbit, it will spend another two to three months surveying the candidate landing sites before landing.進入軌道後，"天問一號"還會在著陸前花兩三個月對候選著陸點進行考察。

>US move angers TikTok users美欲封禁TikTok引爭議The TikTok community is pouring out its frustration over the possible ban by the US government and is expressing support for the company on social media. 美國政府可能實施的封禁在TikTok社區引發強烈沮喪情緒，大批網友在社交媒體上聲援TikTok公司。The app has gained in popularity during the COVID-19 pandemic, since many view it as a source of entertainment and education. 這款應用程式在新冠肺炎疫情期間走紅，許多人將其視為娛樂和教育的來源。Many young TikTok users are so desperate to keep the app around that they launched a movement called "saveTikTok" on social media. 許多年輕用戶太想留住TikTok還在社交媒體上發起了"拯救TikTok"運動。TikTok star Griffin Johnson tweeted on Saturday that it had given him "a lot of friends & memories that I will forever be thankful for". TikTok明星博主格裡芬詹森8月1日發布推文稱，TikTok帶給他太多朋友和回憶，他將永遠感激這一平臺。TikTok CEO Kevin Mayer said in a blog post on Wednesday that the reason his company was under scrutiny was because of its Chinese origins. TikTok執行長凱文梅耶爾在7月29日發布的一則博文中稱，TikTok面臨審查是因為它有"中國血統"。Under the grand framework of China-US strategic gaming, the rise of TikTok is symbolic of the challenge to US dominance in information technology, said Shen Yi, professor and director of the Research Institution of Global Cyberspace Governance at Fudan University in Shanghai. 上海復旦大學網絡空間國際治理研究基地主任沈逸教授稱，在中美戰略博弈的大框架下，TikTok崛起代表了中國正對美國在信息技術領域的優勢發起挑戰，這可能引起白宮的狂怒。"This is likely to cause fury in the White House," he said. Shen said TikTok's success, especially its popularity among the younger generation of American users, stands to showcase a true China to local audiences and could help destroy the "evil China image" that the Trump administration has long been fabricating. "This is a fight for supremacy over discourse and ideology."沈逸表示，TikTok的成功，尤其是在美國年輕一代中流行，將給當地受眾展示真實的中國，這可能幫助打破川普政府長期以來捏造的邪惡中國的形象，這是一場話語權和意識形態領域的戰爭。

>Crew Dragon's splashdown美載人'龍'飛船返回地球The SpaceX Crew Dragon "Endeavour" spacecraft carrying two NASA astronauts parachuted to a splashdown in the Gulf of Mexico off the coast of Florida on Sunday, completing a two-month mission to the International Space Station (ISS). 搭載兩名美國航天局(NASA)太空人的美國太空探索技術公司(SpaceX)奮進號"龍"飛船在完成為期兩個月的國際空間站任務後，8月2日返回地球，濺落在佛羅裡達州海岸的墨西哥灣。When the spacecraft splashed down off the coast of Pensacola, Florida at 2:48 pm EDT Sunday, the SpaceX recovery vessel GO Navigator was waiting at the landing zone. 美國東部時間14時48分，飛船濺落在佛羅裡達州彭薩科拉海岸，SpaceX回收船GO Navigator在著陸區等待。The recovery teams then opened the hatch and retrieved NASA astronauts Robert Behnken and Douglas Hurley, according to NASA live broadcast. NASA的直播畫面顯示，回收小組打開艙門，NASA太空人羅伯特本肯和道格拉斯赫爾利被抬出艙。The return of the test flight with the two astronauts from the ISS marks the first splashdown of an American crew spacecraft in 45 years, said NASA. NASA表示，此次載人試飛任務中，兩名太空人成功從國際空間站返回，這標誌著45年來美國載人飛船首次以濺落方式返回地球。It also wrapped up the test flight for the first commercially owned and operated crewed spacecraft under NASA's Commercial Crew Program.這也代表了NASA商業載人項目下首個由私營企業建造和運營的飛船承擔的載人試飛任務的圓滿成功。
