SpaceX pushed Starlink deeper into orbit on July 9. B1067 completed its 36th flight and lifted the Starlink 10-42 batch from Cape Canaveral at 5:25 a.m. EDT. The booster’s landing kept its place as the most-flown orbital rocket booster in history.
That flight matters because the constellation already stood at 12,472 launched satellites, with 10,777 in orbit and 10,761 operational. SpaceX is not just replacing capacity one launch at a time. It is building on an operational network that already serves Earth orbit at scale.
B1067 at 36 flights
B1067’s 36-flight mark is the clearest sign of how far SpaceX has pushed booster reuse. The same hardware flew again from Cape Canaveral Space Force Station’s Launch Complex 40, and the Starlink 10-42 payload went up without a visible pause in the cadence of launches. Readers tracking launch reliability get the practical takeaway here: the hardware is being turned around often enough to keep adding satellites while preserving the booster record.
The record is not a marketing label. It is a reuse milestone that matters because every additional flight reduces the need to field a fresh booster for each mission. That lowers the operational burden on SpaceX’s launch system and keeps the launch schedule moving for Starlink deployments.
FCC filing and 100,000 satellites
On July 9, SpaceX also filed with the FCC to operate a next-generation megaconstellation of 100,000 Starlink satellites. Each proposed satellite would weigh roughly 4,400 pounds. The filing signals a regulatory push toward a network that is far larger than the one already in service, and it ties the B1067 flight to a broader buildout rather than a one-off launch.
For users, the important detail is scale. A larger fleet can mean more room to absorb outages, expand coverage, and keep the system supplied with fresh spacecraft. The harder question is spectrum and orbital management, because a filing for 100,000 spacecraft is only the opening step in a regulatory process, not a permission slip.
STARLINK-4621 and reentries
The same operational picture also carries friction. STARLINK-4621 faced a critical conjunction with the defunct SL-18 R/B on Jul 9, 23:44 UTC, with a minimum range of 0.011 km and unity collision probability. Five Starlink satellites are also predicted to reenter Earth’s atmosphere between Jul 10 and Jul 13, 2026, with decay windows of 8 to 17 hours, which puts disposal and collision-avoidance work in the same frame as expansion.
Whether SpaceX plans any specific operational changes or avoidance maneuver for STARLINK-4621 is not answered in the filing or launch record. The immediate story is that the fleet is growing fast, but the same system still has to manage close approaches and end-of-life reentries while it does so.
