Hubble Network has become the first company in history to establish a Bluetooth connection directly to a satellite — a critical technology validation for the company, potentially opening the door to connecting millions more devices anywhere in the world.

The Seattle-based startup launched its first two satellites to orbit on SpaceX’s Transporter-10 ride-share mission in March; since that time, the company confirmed that it has received signals from the onboard 3.5mm Bluetooth chips from over 600 kilometers away.
