Starlink lanserar internet från rymden 2020

Starlink is a satellite constellation being constructed by American company SpaceX, for a new space-based Internet. The constellation is built off a custom low-cost, high-performance satellite bus and ground transceivers. SpaceX also plans to sell satellites for military, scientific or exploratory purposes. SpaceX has deployed 62 satellites as of May 2019 and plans to deploy 60 more per launch, at a rate of one launch every two weeks beginning November 2019. In total, nearly 12,000 satellites will be deployed and later possibly up to 42,000 satellites. The additional 30,000 satellites were added to the plan in 2019 after FCC submitted an application on behalf of SpaceX with ITU. The 12,000 satellites are planned to orbit in three orbital shells by the mid-2020s: initially placing approximately 1,600 in a 550-kilometer (340 mi)-altitude shell, subsequently placing 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). The total cost of the decade-long project to design, build and deploy such a network was estimated by SpaceX in May 2018 to be on the order of US$10 billion. Concerns have been raised about the long term danger of space junk resulting from placing thousands of satellites in orbits above 1000 km where orbit decay times are measured in thousands of years.Product development began in 2015, and two prototype test-flight satellites were launched in February 2018. A second set of test satellites and the first large deployment of a piece of the constellation occurred on 24 May 2019 (UTC) when the first 60 operational satellites were launched. Initial commercial operation of the constellation could begin in 2020.The SpaceX satellite development facility in Redmond, Washington, houses the research, development, manufacturing and on-orbit control operations for the satellite Internet project.
