A strange and large streak of light was spotted in the sky on Friday, May 16, 2025. The unusual phenomenon has sparked interest among space enthusiasts. According to SpaceWeather.com, a Chinese rocket launch startup named Landspace launched the ZhuQue-2E rocket from the Jiuquan Satellite Launch Center at 4:12 UTC. The rocket carried six satellites into orbit, including a synthetic aperture radar and multiple space science spacecraft.
The white streak observed later may have been caused by a de-orbit burn or circularization burn for the deploying satellites, as reported by SpaceWeather.com. An investigation into the cause of the mysterious light is ongoing to determine its exact origin and purpose.
