A rocket carrying six satellites built by Airbus SE and partner OneWeb blasted off from French Guiana on Wednesday, the first step in a plan to give millions of people in remote and rural areas high-speed internet beamed down from space.

A successful launch could mark a new era in the satellite services industry. Companies like Elon Musk¡¯s SpaceX, LeoSat Enterprises, and Canada¡¯s Telesat are working to enable data networks with hundreds or even thousands of tiny satellites that orbit closer to Earth than traditional communications satellites, a radical shift made possible by leaps in laser technology and computer chips.

The growth in satellites will spur demand for rocket launch services, and a handful of venture-backed rocket companies are developing smaller boosters to deploy the smaller satellites at lower cost.
