A year ago, on February 19, 2025 at around 4:45 a.m., bright dots with long tails could be seen in the sky in northern Germany. A discarded second stage of a Falcon 9 rocket from Elon Musk’s space company Space X had spectacularly entered the Earth’s atmosphere. Due to the friction of air molecules, the rocket stage was braked sharply at an altitude of 100 to 80 kilometers before it broke apart into numerous pieces of debris that eventually burned up as points of light in the sky.
