Elon Musk's internet from space: 60 new SpaceX satellites bring US service closer

Elon Musk’s SpaceX on Monday launched 60 more Starlink satellites into low Earth orbit, bringing the company’s Starlink satellite broadband internet service closer to its planned mid-2020 go-live date for the US and Canada. 

The Monday launch of SpaceX’s Falcon 9 rocket from Cape Canaveral Air Force Station, Florida, is one of six more launches required to deliver coverage to North America. It was the second Falcon 9 launch carrying a payload of 60 Starlink satellites.  

SpaceX launched the first 60 “production design” Starlink satellites in May, representing a small fraction of the 12,000 the Federal Communications Commission has approved Starlink to operate in space. Starlink may one day have as many as 30,000 Starlink satellites in operation.

Elon Musk has said Space X needs about 400 satellites to provide “minor” coverage and 800 for “moderate” coverage of North America.

The rocket company will be able to launch a global Starlink satellite broadband service after 24 additional launches, at which point the North American service is scheduled to be available. With 30 launches, SpaceX would have 1,800 Starlink satellites.    

Each compact Starlink satellite weighs 573lb (260kg) and features a solar array for power, an ion thruster propulsion system, navigation sensors, and four powerful antennas for beaming internet to Earth. 

The 60 satellites onboard the Falcon 9 on Monday were released about an hour after liftoff into a 174-mile-high (280km) orbit and then, using the onboard propulsion system, were moved into their operational position. Their orbit is lower than the May batch, which lacked the equipment necessary to create a mesh network

SpaceX says it has upgraded the design of the satellites since May to increase spectrum capacity and maximize their use of the Ka and Ku bands. 

SpaceX promises to provide fast, reliable internet to areas with little or no connectivity, such as poorly served rural communities. 

Assuming SpaceX meets its mid-2020 target, it could be ahead of the FCC’s $1.98bn Connect America Fund (CAF) II rural broadband program, which ISPs are rolling out over the next 10 years

According to Microsoft, 162 million people across the US, mostly in rural areas, don’t have access to broadband speeds. The FCC estimates that number to be just 21 million.

SpaceX hasn’t determined pricing yet, but one group of consumers it will target are those who currently pay $80 for a poor broadband service, SpaceX chief operating officer Gwynne Shotwell said last month.   

SpaceX and the US Air Force Research Laboratory have demonstrated a 610Mbps connection to the cockpit of an inflight US military C-12 twin-engine turboprop aircraft. But the plan is to deliver to 1Gbps per user with low latency, projected to be around 25ms.

SpaceX will also require users to install a “beautiful” user terminal, but it’s not known yet whether it will be a standalone device or serve as a cable modem/router.
