Why are Starlink's space lasers such a big deal?
Without lasers, a satellite has to send your data straight back down to a ground station it can see. No ground station in range, no internet.
Starlink skips that step. 1. Each V2 Mini satellite carries 3 lasers that talk directly to other satellites. 2. More than 24,000 of these lasers are up there now, forming one mesh around the planet. 3. Each link runs at up to 200 Gbps. SpaceX says hardware next year moves that to 400. 4. Data can hop from satellite to satellite until it finds a ground station, even on the other side of an ocean.
That's why it works on a cruise ship in the middle of the Pacific, and why it kept working in Spain and Portugal when the whole power grid went down in April 2025.
Smarter laser routing also cut 30 to 40 ms of latency in Asia and Africa in 2025.
