Build a powerful enough laser, and you can shine it into space. Aim it well, and you can blind satellites.
Megaconstellations of satellites will visually clutter the night sky, disrupting astronomical research. And the environmental damage caused by these satellites is still unknown.
Ten small satellites were launched from 11km above Earth’s surface.
The shift toward mega-constellations is a challenge for global space governance.
So long as small satellites are in low Earth orbit – and most likely they will be – the Earth’s “vacuum cleaner” will clean them up.
Back of the net! Litter-picking mission will leave space junk caught up in a web.
Just about anyone can get a tiny, cheap satellite into orbit these days. As we consider how to deploy them responsibly, inspiration comes from an amateur community of enthusiasts.
