The skies above Earth are filling fast. With hundreds of thousands of satellites planned by China, SpaceX, and Blue Origin, the radio frequency bands that allow them to communicate are under increasing strain. The congestion is already causing interference that disrupts Earth imaging and astronomical research. One European start-up believes it has found a solution: Astrolight, a Lithuanian space-tech company, is developing laser-based communication systems that can transmit vastly more data, immune to interference, and potentially unlock a new era of high-speed, secure satellite connectivity.
