en.Wedoany.com Reported - US-based SpaceX recently conducted two consecutive Starlink satellite launch missions, sending 53 broadband communication satellites into low Earth orbit within two days, continuing to expand the Starlink satellite internet infrastructure composed of in-orbit satellites, inter-satellite laser links, ground stations, and user terminals.
On July 9, SpaceX launched a Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida, sending 29 Starlink satellites into low Earth orbit. The rocket's first stage subsequently landed on an autonomous drone ship at sea, and the satellites completed orbital deployment.
One day later, SpaceX executed the Starlink 17-48 mission from Space Launch Complex 4E at Vandenberg Space Force Base in California, sending another 24 satellites into low Earth orbit. The Falcon 9 first-stage booster used for this mission completed its 35th flight, and the satellites separated and deployed after launch.
The two missions deployed a total of 53 satellites, allowing SpaceX to continue increasing the number of in-orbit nodes in the Starlink network. Unlike terrestrial mobile communication networks that rely on base stations and fiber optics to expand coverage, low Earth orbit satellite internet requires continuous deployment of satellites across multiple orbital layers to provide uninterrupted communication capabilities as satellites pass over different regions.
Starlink's infrastructure is not limited to in-orbit satellites. The network architecture disclosed by SpaceX also includes an inter-satellite laser mesh network, satellite ground stations, optical communication equipment, spectrum resources, and receiving terminals for fixed and mobile users. Satellites are responsible for receiving and forwarding data in orbit, inter-satellite laser links connect different satellites, and ground stations handle data exchange between the satellite network and the terrestrial internet backbone.
Continuously increasing the number of satellites can raise the density of satellites available simultaneously over a single area and enhance network capacity for broadband communications, mobile communications, and remote area access. After new satellites are deployed, they must undergo orbital adjustments, equipment checks, and network integration before becoming fully operational nodes in the Starlink communication system.
In the first half of 2026, SpaceX deployed 1,589 Starlink satellites, up from 1,489 in the same period in 2025, an increase of 100 satellites. In the full year of 2025, SpaceX deployed a total of 3,180 Starlink satellites. Based on the launch pace in the first half of 2026, the company continues to expand its low Earth orbit communication constellation through high-frequency launches.
As of mid-2026, SpaceX has launched over 12,400 Starlink satellites cumulatively, with nearly 11,000 still in orbit. Since some early satellites need to be retired or deorbited, the company must not only add new orbital nodes but also continuously launch satellites to replace aging equipment, maintaining constellation size and network coverage.
The deployment of 53 satellites in two days continues SpaceX's model of batch-building low Earth orbit communication constellations using Falcon 9 rockets. The July 9 mission launched from the U.S. East Coast, and the July 10 mission launched from the U.S. West Coast, with both launch sites sharing Starlink satellite deployment duties to shorten the interval between missions targeting different orbits.
SpaceX currently primarily uses Falcon 9 for Starlink constellation missions. The company plans to deploy next-generation Starlink V3 satellites using the larger-capacity Starship system. The new satellites will be equipped with higher-capacity communication equipment and laser links, but the timeline for full-scale batch deployment still depends on Starship testing, launch licensing, and satellite system validation progress.
From a construction perspective, the Starlink low Earth orbit communication infrastructure is simultaneously advancing satellite manufacturing, batch launches, orbital networking, laser link connections, and ground network access. With these 53 satellites now in orbit, the focus of Starlink network construction will remain on increasing the number of in-orbit satellites, supplementing orbital capacity, replacing early equipment, and improving connections between satellites and ground communication systems.
