SpaceX Launches 81 Satellites on Major Rideshare Mission

  • 2 hours ago
  • 4 min read



Early Tuesday morning, SpaceX successfully sent another large group of satellites into orbit, continuing its busy launch schedule for 2026.


A Falcon 9 rocket lifted off from Vandenberg Space Force Base in California at 3:12 a.m. EDT on July 7, carrying 81 separate payloads.


The launch marked the 17th mission in SpaceX's Transporter program, which allows multiple organizations to share the cost of a single rocket launch. The company also operates another rideshare program called Bandwagon, which has completed four missions so far.


Together, the previous Transporter and Bandwagon launches have delivered more than 1,800 satellites and other payloads into Earth orbit. The very first Transporter mission, launched in January 2021, still holds the world record for the largest number of payloads launched on a single rocket, carrying 143 satellites.

This latest mission transported a wide variety of spacecraft, including CubeSats, microsatellites, hosted payloads, and orbital transfer vehicles. Some of these transfer vehicles will release their satellites into different orbits at a later stage, making the mission even more versatile.


One of the most significant spacecraft aboard the rocket was CAS500-4, a South Korean Earth-observation satellite weighing approximately 500 kilograms (1,100 pounds). It is the fourth satellite in South Korea's planned CAS500 constellation, which is designed to monitor forests, farmland, and other environmental conditions from low Earth orbit.


Meanwhile, the Falcon 9's reusable first-stage booster successfully completed another landing, touching down on SpaceX's drone ship "Of Course I Still Love You" in the Pacific Ocean only 8½ minutes after liftoff. This marked the 11th flight for that particular booster, highlighting the company's continued emphasis on rocket reusability.


After separating from the booster, the rocket's upper stage continued carrying the payloads toward low Earth orbit (LEO). The deployment process began roughly 50 minutes after launch.


Transporter-17 became SpaceX's 79th Falcon 9 launch of 2026, underscoring an exceptionally active year for the company. Nearly 80% of all Falcon 9 missions this year have focused on expanding the Starlink satellite network, SpaceX's global broadband internet constellation.


The mission demonstrates not only the growing demand for affordable satellite launches but also the increasing importance of rideshare missions in making space more accessible for governments, research organizations, and commercial companies around the world.
