近日，海外社交平台出现一则所谓“中国空间站造假”的谣言，称中国天宫空间站相关视频画面中一杯装满水的杯子未在失重环境中漂浮。“德国之声”20日发布事实核查报道，对此谣言予以辟谣。
The German broadcaster Deutsche Welle has debunked a rumor circulating on overseas social media that claims a video from China's Tiangong space station was fabricated. The false claim is based on a screenshot of a water-filled cup not floating in microgravity.
其中一则广为传播的质疑网帖截图
据环球时报记者核实，这张截图来自2021年12月9日的“天宫课堂”第一课。当时，神舟十三号航天员王亚平、翟志刚和叶光富在空间站进行太空授课，课程内容被翻译成多种语言并向全球传播。
The image was in fact taken from the first lesson of Tiangong Classroom on Dec 9, 2021, where Shenzhou-13 astronauts Wang Yaping, Zhai Zhigang, and Ye Guangfu delivered a live science lesson later broadcast worldwide.
对于为何水杯和水没有在失重环境中漂浮，中国航天科技集团等多家权威机构曾解释说，水杯为了便于实验而被固定在操作台上；而杯中液体之所以不会飘散，是由于水的表面张力在发挥作用。
To refute the rumors, the China Manned Space Engineering website later released a behind-the-scenes video showing an astronaut securing the cup with adhesive strips and squeezing water into it through a straw. Floating droplets confirmed the weightless environment.

尽管中国方面此前已对此作出了详细的说明，但在部分反华账号的煽动下，这一谣言于本月初再次在多个海外社交媒体平台传播，误导了海外网民。
Although China had already provided a detailed explanation, the rumor resurfaced on multiple overseas social media platforms earlier this month, misleading users.
对此，德国航空航天中心发言人安德里亚斯·舒茨、不来梅大学专家安杰尔·平格尔向“德国之声”证实，他们从专业角度可以确认视频内容不存在造假。专家们提供了一张视频截图称，中国空间站进行实验时，被放入水中的乒乓球并未漂到水面，这正是微重力环境下的正常表现。
A spokesperson from the German Aerospace Center and an expert at the University of Bremen confirmed to Deutsche Welle that the video showed no signs of fabrication. They noted that a table tennis ball placed in water did not rise to the surface, which is consistent with microgravity conditions.
