On the morning of July 15, at China’s Wenchang Space Launch Site, the Long March-7 Yao-10 carrier rocket successfully launched the Tianzhou-9 cargo spacecraft.

The spacecraft's takeoff created a stunning visual spectacle in the night sky known as the “space jellyfish.”

As the rocket ascended, its exhaust plume formed a distinctive umbrella-shaped cloud high in the atmosphere - a large, glowing head with a trailing smoky tail - resembling a giant jellyfish swimming slowly across the sky.

This phenomenon, often referred to as a “rocket cloud,” results from a “twilight effect” — the rocket exhaust interacting with light in the upper atmosphere under specific conditions, producing mesmerising patterns.

About three hours after launch, Tianzhou-9 successfully docked with the rear port of the Tianhe core module of China’s space station.

7月15日清晨，中国文昌航天发射场。长征七号遥十运载火箭成功发射天舟九号货运飞船，顺利将其送入预定轨道。此次发射任务不仅标志着中国航天事业迈入新阶段，更在夜空中上演了震撼的“太空水母”的视觉奇观。

随着火箭升空，其尾部在高空形成了独特的伞状云团，头部膨大、尾部拖曳长烟，宛如一只巨大的水母在夜空中缓缓游动。

这种现象被称为“火箭云”，是火箭与大气层相互作用产生的“暮光效应”。当火箭在特定条件下发射时，其尾焰与大气层中的光线相互作用，形成类似水母的美丽轨迹。

天舟九号货运飞船在发射约3小时后，成功对接于空间站天和核心舱后向端口，实现了中国货运飞船3小时交会对接模式的常态化实施。

天舟九号上行物资装载重量创新高，约为6.5吨，包括航天员系统乘员物资、空间站系统平台物资以及空间应用系统、航天医学实验领域与航天技术实验领域实验样品和设备设施等。
