SpaceX is developing a low latency, broadband internet system to meet the needs of consumers across the globe. They have a Starlink.com website. Enabled by a constellation of low Earth orbit satellites, Starlink will provide fast, reliable internet to populations with little or no connectivity, including those in rural communities and places where existing services are too expensive or unreliable.
Marcus House has image with 42000 and 12000 satellites around the world and a video describing the latest information.
Starlink is targeted to offer service in the Northern U.S. and Canadian latitudes after six launches, rapidly expanding to global coverage of the populated world after an expected 24 launches. SpaceX is targeting two to six Starlink launches by the end of this year.
Each Starlink satellite weighs 227 kilograms and have krypton ion engines.
SpaceX has deployed 62 Starlink satellites. They plan to deploy 60 more per launch, at a rate of one launch every two weeks beginning in November 2019. In total, nearly 12,000 satellites will be deployed by the mid-2020s and an extension to 42,000. The initial 12,000 satellites are planned to orbit in three orbital shells: first placing approximately 1,600 in a 550-kilometer (340 mi)-altitude shell, then approximately 2,800 Ku- and Ka-band spectrum satellites at 1,150 km (710 mi) and approximately 7,500 V-band satellites at 340 km (210 mi).
Keeping Space Clean
Starlink is on the leading edge of on-orbit debris mitigation, meeting or exceeding all regulatory and industry standards.
At end of life, the satellites will utilize their on-board propulsion system to deorbit over the course of a few months. In the unlikely event the propulsion system becomes inoperable, the satellites will burn up in Earth’s atmosphere within 1-5 years, significantly less than the hundreds or thousands of years required at higher altitudes.
Here are images and information on the collision avoidance systems, ion drives, flat stacking for launch and solar panels.
