SpaceX's Falcon 9 Launches Starlink Group 10-29: Expanding Global Connectivity
On July 30, 2025, SpaceX successfully launched its Falcon 9 rocket from Cape Canaveral Space Force Station in Florida, deploying 28 satellites as part of Starlink Group 10-29. This mission marks another milestone in the company's ambitious effort to build a vast satellite constellation for global broadband internet. The launch, occurring under clear skies, saw the first-stage booster land precisely on a droneship in the Atlantic Ocean, underscoring SpaceX's reusable rocket technology.
The primary objective of this mission is to bolster the Starlink mega-constellation, which aims to provide high-speed, low-latency internet to underserved regions worldwide. Each of the 28 satellites weighs approximately 300 kilograms and is equipped with advanced laser communication systems for inter-satellite links, enabling data transfer without relying solely on ground stations. These satellites operate in low Earth orbit (LEO) at about 550 kilometers altitude, offering improved coverage and reduced signal delay compared to traditional geostationary satellites. Payload capabilities include handling up to 100 Mbps download speeds for users, with the potential for upgrades via software updates. This batch contributes to Starlink's goal of seamless connectivity for remote areas, maritime vessels, and aircraft, while also supporting emergency communications in disaster zones.
At the heart of the mission is the Falcon 9 Block 5 rocket, SpaceX's workhorse launch vehicle. Standing 70 meters tall with a diameter of 3.7 meters, it features two stages powered by Merlin engines: nine on the first stage for liftoff and one vacuum-optimized Merlin on the second for orbital insertion. The rocket can deliver up to 22,800 kilograms to LEO, making it ideal for deploying multiple satellites in a single flight. Key technical specifications include its reusability features, such as grid fins for controlled descent and landing legs on the booster. The Block 5 variant, introduced in 2018, incorporates enhancements like improved heat shielding and stronger thrust structures, allowing for up to 10 reuses per booster with minimal refurbishment.
Falcon 9's performance history is impressive, with over 300 successful launches by mid-2025 and a success rate exceeding 98%. Reusability has drastically cut costs—from an estimated $60 million per launch to around $30 million—enabling frequent missions. Notable achievements include the first booster reuse in 2017 and the record-breaking 20
