Was it as recently as seven years ago that two tiny prototypes called Tintin A and Tintin B slipped quietly into low-Earth orbit? Today, SpaceX passed the astounding milestone of 10,006 Starlink satellites launched, confirmed by astrophysicist Jonathan McDowell, one of the quickest buildouts of any space-based infrastructure in history.
On October 19, two Falcon 9 rockets took off hours apart from opposite coasts of the United States Cape Canaveral in Florida and Vandenberg Space Force Base in California adding 56 more satellites to the constellation. The launch in California carried the 10,000th spacecraft, prompting a celebratory comment from SpaceX’s launch director: “From Tintin to 10,000.”
Go Starlink, go Falcon, go SpaceX. Each group of 28 satellites was released to an altitude of approximately 260 kilometers prior to making plasma engine burns to get to their operational altitude of 535 kilometers.
Its operational constellation is now at 8,664 functioning satellites, 7,448 of which are already in final orbital location. That’s as many as 70% of all operational satellites in orbit, by European Space Agency estimates, highlighting SpaceX’s leadership in the industry. Its subscriber count has also passed 7 million worldwide, and its network is being set up to support direct-to-smartphone connectivity with the use of $17 billion worth of purchased spectrum rights in order to extend mobile coverage.
The latest Starlink generation, the V2 Mini, has solar arrays measuring 30 meters tip-to-tip and weighing less than 600 kilograms. They represent a major improvement from the first-generation V1 model but will be replaced shortly by the Starlink V3 platform. The V3 satellites, up to 2,000 kilograms, in weight, will provide gigabit connectivity and bring 60 terabits per second of downlink capacity to the network more than 20 times that of a V2 Mini launch. Being too big and heavy for Falcon 9, they will be deployed on the Starship rocket, which will deliver 60 V3 units on each mission from next year.
SpaceX’s satellite lifecycle management is as extreme as its launch rhythm. Every Starlink is built to last five years in operation, then it does a controlled deorbit burn so that it disintegrates totally in the atmosphere. McDowell has seen one to two Starlinks reentering per day on average in 2025, a number that will increase to five per day as the constellation expands. Though the burn-ups present no physical threat to humans, there remains scientific examination into whether and how materials that are vaporized during reentry can cause atmospheric effects.
Along with its satellite growth, SpaceX is expanding the limits of reusability for rockets. The launch from Florida was the 31st mission for a single Falcon 9 booster, a record for the company, while the booster for California’s mission had completed its 11th mission. With more than 20 Falcon 9 boosters in regular rotation, the engineers are now certifying them for as many as 40 flights each, a feat that can change the dynamics of cost-effectiveness in orbit transport. Operations in recovering them are still very accurate: both boosters landed on autonomous drone ships in position in the Atlantic and Pacific oceans.
The tempo of operations is unrelenting. SpaceX’s 2025 launch count for Falcon 9 now totals 132 missions, tied with last year’s record, with a number more planned before the year’s end. With Falcon Heavy flights included, the business’ 2024 total hit 134 launches the most of any single rocket family in a calendar year. With the upcoming shift to Starship for V3 launches, the size of future missions will dwarf present capability, both in terms of payload and network footprint.
