This startup wants to wipe space clean
With sticky satellites no less.
According to the European Space Agency, about 129 million pieces of debris are currently orbiting Earth. 34,000 of these are 10 cm wide or larger. Each one has the potential to damage one of the 2,300 active satellites that run humanity’s science, communications and navigation.
Inspired by prospects of future space travel, Vlad Sidnikov saw the need to prevent debris collisions. He founded StartRocket to develop the Foam Debris Catcher, a number of small satellites that catch junk with jets of polymer foam. The foam traps the debris, eventually burning it in the Earth’s atmosphere upon reentry.

This isn’t the first space related venture of Sidnikov. In January 2018, US-New Zealand company Rocket Lab launched the Humanity Star, a geodesic satellite engineered to be visible from Earth.
The Humanity Star lead Sidnikov to the idea of orbital billboards: massive displays of satellites visible from Earth. However, the backlash against both Humanity Star and Sidnikov’s own space advertising made him reconsider. Rather than polluting the night sky, he decided to do the opposite.
His next venture would become StartRocket. Sidnikov engaged a team of space and chemical industry experts to develop the foam technology, aiming to launch a first satellite by 2022 to test the behavior of the polymer foam in space. If it meet expectations, then a first functional Foam Debris Catcher could be launched in 2023.
Other methods to clean up space have been proposed, such as satellites with nets and harpoons, but Sidnikov claims the Foam Debris Catcher is much more safe and affordable. “It’s basically a 3D printer latched on to a satellite.”
Criticism
Some concerns were raised over the offensive potential of the Foam Debris Catcher — whether it could accidentally or deliberately bring down active satellites. It would not be inconceivable for civilian and scientific technology to have military potential. After all, the Space Shuttle had the capability of plucking satellites out of orbit.
