According to the news on July 28, SpaceX, a US space exploration technology company, did not carry out any launch activities in July this year, but it plans to return to normal in August, launch Falcon 9 rockets from California and Florida, and start deploying the star chain Internet satellite to a new orbit < p > < / P > < p > according to several sources, SpaceX is preparing for at least two satellite chain launches in August. The company will launch Falcon 9 rocket at Vandenberg space force base in California as early as August 10. The second Falcon 9 rocket launch is planned to be carried out in Cape Canaveral in mid August to put the star chain satellite into orbit < p > this will be SpaceX's first launch since June 30. In the company's full launch plan, this is an unusually long interval. In the first half of this year, SpaceX launched 20 Falcon 9 rocket missions, mainly for the company to deploy its own star chain network. SpaceX's most recent satellite launch mission took place on May 26 < p > analysis by Jonathan McDowell, an astronomer at Harvard Smithsonian Center for Astrophysics, shows that since then, SpaceX has activated hundreds of star chain satellites previously put into orbit, increasing the number of satellites in operation from about 950 to more than 1300 < p > more than 200 other satellite chains are in orbit 341 miles (550 kilometers) above the earth and drift to their intended operating positions at an inclination of 53 degrees to the equator < p > SpaceX has obtained regulatory approval from the Federal Communications Commission (FCC), and can eventually launch and operate up to 12000 Internet relay satellites. The early stage of SpaceX's satellite chain Internet included the launch of 4408 satellites into five "orbital shells" in low earth orbit < p > to date, SpaceX has launched 1740 satellite chain satellites, including retired prototype satellites, more than the sum of all other commercial satellite projects. Most satellites are launched into 53 degree inclination orbit, which is the first of the five orbital shells that SpaceX plans to complete the full deployment of satellite chain Internet < p > with more than 1500 active satellites in this orbital shell, SpaceX is transitioning to a new stage of satellite chain deployment plan The completion of the first orbital shell of the < p > Star chain Internet will enable the network to provide high-speed and low latency Internet services to low latitudes such as the southern United States. Some satellites are deployed in the first orbital shell, which can initially serve the northern United States, Canada, Europe and high latitudes in the southern hemisphere. SpaceX is currently providing temporary Internet services to test users in the United States, Canada, the United Kingdom, Germany, New Zealand, France, Austria, Belgium and the Netherlands < p > the satellite chain mission scheduled to be launched from Vandenberg next month is called "Starlink 2-1", and these satellites will begin to fill new orbital shells. SpaceX's application to the FCC shows that the landing platform of its Falcon 9 rocket booster (i.e. unmanned recovery ship) will be placed in the Pacific Ocean off the coast of lower California. This position indicates that the target of the launch is an orbit inclined by 70 degrees < p > SpaceX submitted a similar application to the FCC for launching the satellite chain satellite in Cape Canaveral in August. It shows that SpaceX's unmanned recovery ship will be parked in the Atlantic Ocean, which is consistent with the rocket trajectory tilted 53.2 degrees. After the launch in mid August, there will be more satellite chain satellite launch missions. SpaceX is expected to launch the satellite chain from Vandenberg on average once a month next year, and the launch of Cape Canaveral will also be carried out regularly < p > SpaceX has not disclosed what design changes have been introduced into the next-generation satellite chain, which is produced at its Redmond, Washington facility. The fully loaded Falcon 9 rocket can carry 60 first generation satellites into orbit in each mission, but it is unclear whether this number will change in future flights < p > in January this year, Elon Musk, CEO of SpaceX, said that from 2022, SpaceX would introduce laser inter satellite links to all satellite chains. He said on twitter that the satellite chain satellites entering polar orbit this year will be upgraded. SpaceX launched 10 satellite chains during its carpool mission in January, sending them into a polar orbit of 97.6 degrees. Last month, three other satellites were launched into similar orbits during a carpool mission < p > these satellites have the characteristics of laser inter satellite links, allowing satellites to transfer data and Internet traffic to each other without routing through ground stations. This upgrade will enable SpaceX to provide Internet connection services near the poles and other areas without ground stations（ Small) < / P > < p >
