SpaceX launches 60 mini satellites in quest for global internet coverage

WATCH: SpaceX's Falcon rocket successfully launches 60 satellites on fourth flight

SpaceX launched 60 mini satellites Monday, the second batch of an orbiting network meant to provide global internet coverage.

The Falcon rocket blasted into the morning sky, marking the unprecedented fourth flight of a booster for SpaceX. The compact flat-panel satellites — just 575 pounds (260 kilograms) each — will join 60 launched in May.

SpaceX founder and chief executive Elon Musk wants to put thousands of these Starlink satellites in orbit, to offer high-speed internet service everywhere. He plans to start service next year in the northern U.S. and Canada, with global coverage for populated areas after 24 launches.

Last month, Musk used an orbiting Starlink satellite to send a tweet: “Whoa, it worked!!”

“These boosters are designed to be used 10 times. Let’s turn it around for a fifth, guys,” company’s launch commentator said.

This also marked the first time SpaceX used a previously flown nose cone. The California-based company reuses rocket parts to cut costs.

Stacked flat inside the top of the rocket, the newest satellites were going to manoeuver even higher following liftoff, using krypton-powered thrusters. SpaceX said there was a potential problem with one of the 60 that could prevent it from moving beyond its initial 174 mile-high (280 kilometre-high) orbit. In that case, the faulty satellite will be commanded to re-enter and burn up harmlessly in the atmosphere.

Each satellite has an autonomous system for dodging space junk. In September, however, the European Space Agency had to move one of its satellites out of the way of a Starlink satellite. SpaceX later said it corrected the problem.

SpaceX is among several companies interested in providing broadband internet coverage worldwide, especially in areas where it costs too much or is unreliable. Others include OneWeb and Jeff Bezos’ Amazon.
