techcrunch.com Jagmeet Singh 2025-07-31 19:12:21

The startup is tackling a persistent problem in space communications. Satellites frequently go offline during parts of their orbit due to dead zones — periods when they are not in the line of sight of a ground station

This has become more evident in recent weeks, when we saw a pair of rocket launches carrying top-secret military payloads, the release of a mysterious object from a Russian mothership in orbit, and a sequence of complex formation-flying maneuvers with a trio of satellites nearly 400 miles up. In isolation, each of these things would catch the attention of Western analysts. Taken

But before quantum advantage drastically changes information technology as we know it, researchers have yet to address the many hurdles that are preventing quantum computers from entering into the mainstream.
