Experts from the Federal Office of Civil Protection (FOCP) were quickly able to clear up the situation: according to them, the fast-moving, highly luminous celestial spectacle on Tuesday evening was a Starlink satellite that entered the Earth’s atmosphere over Switzerland and was visible in the south-west. The Space Situational Awareness Centre of the German Armed Forces provided the FOCP with this information, said a spokesperson.
Starlink satellites belong to Elon Musk’s aerospace company SpaceX. They are designed to make fast internet available everywhere and fly at an altitude of around 500 kilometres. SpaceX is by far the largest operator with more than 5,000 Starlink satellites in Earth’s orbit, with around 42,000 planned. According to the company, Starlink satellites pose no threat to public safety.
In several cities in Baden-Württemberg, people called the police because they had seen the glow in the sky at around 9.30 pm.
According to the US space agency NASA, inactive satellites or other space debris at an altitude of less than 600 kilometres fall back to earth within a few years. They usually burn up on re-entry into the atmosphere. Millions of pieces of debris are currently flying around the earth as space debris. In addition, according to the European Space Agency ESA, there are more than 12,500 satellites orbiting the planet – many of which are no longer functional.
This can also pose a threat to space travel. The Chinese space station “Tiangong” was hit by space debris months ago and had to be serviced. The International Space Station (ISS) also has to dodge debris time and again.
