Satelliten mit ultra-darkem ‚vantablack‘ Farbe wird nächstes Jahr in den Weltraum einbreiten, um das große Problem zu bekämpfen

>A satellite painted with one of the darkest materials ever created by humans, known as „[Vantablack](https://www.livescience.com/58561-spray-on-vantablack-coating-is-blackest-material.html),“ will launch into space next year to help researchers try and solve a major issue that’s plaguing astronomers across the globe. There are [more than 14,900 satellites orbiting Earth](https://www.livescience.com/how-many-satellites-orbit-earth). But experts predict that, within the next 50 years or so, the number of active spacecraft in low Earth orbit (LEO) [could rise to more than 100,000](https://www.livescience.com/space/space-exploration/how-many-satellites-could-fit-in-earth-orbit-and-how-many-do-we-really-need). This sharp rise is thanks to private satellite „megaconstellations,“ such as [SpaceX](https://www.livescience.com/tag/spacex)’s [Starlink network](https://www.livescience.com/tag/starlink), which already accounts for more than 60% of the total number of spacecraft circling our planet. These machines are causing several problems that scientists are only just starting to properly understand, including uncontrolled reentries, radio signal interference — and light pollution.
