SpaceX Targets Two California Launches as Orbital Technology Advances

Two planned Falcon 9 launches from Vandenberg Space Force Base in California are set to deliver military communications satellites and Starlink spacecraft into orbit, while separate experiments launched earlier in October test technologies for space-based computing and wireless power transmission. The missions highlight SpaceX's expanding launch schedule and the infrastructure challenges facing emerging orbital data centers.

According to the Desert Sun, the first launch opportunity was scheduled for October 10, 2026, no earlier than 12:29 a.m. Pacific Time, following three scrubs of a military satellite mission initially targeted for October 5. A second Falcon 9 launch was planned for October 12 between 4 p.m. and 8 p.m. Pacific Time, with backup opportunities available the following day if either mission was postponed.

The military mission carries 21 Tranche 1 satellites for the Space Development Agency. The October deployment represents the fourth batch in a planned layered network that will eventually include 154 satellites, providing global military tactical communications and missile defense capabilities by 2027, according to the Desert Sun.

The second mission is scheduled to deploy 27 Starlink satellites, marking the first Starlink launch from Vandenberg since September 19. Both flights use the Falcon 9, a two-stage rocket that has become a central vehicle for SpaceX's launch operations in California and Florida.

Separately, SpaceX's September 28 Starship test flight marked a major milestone when the company's giant launch vehicle reached orbit for the first time and deployed 26 Starlink V3 satellites, according to Space.com. However, the vehicle still faces technical requirements before it can support routine commercial operations and crewed lunar missions.

One major challenge is recovering Starship's upper stage, known as Ship. SpaceX has successfully caught its Super Heavy booster with the launch tower's mechanical arms on three test flights, but it has not yet attempted to catch Ship, which stands 171 feet (52 meters) tall. Space.com reported that Elon Musk raised the possibility of attempting a Ship catch on Flight 15, although the company had not announced an official mission profile or launch date.

Another requirement is transferring propellant between spacecraft in orbit. Such refueling would allow Starship missions to carry enough fuel for journeys to the Moon and Mars. Space.com reported that estimates for a lunar landing campaign range from eight tanker flights to 15 or 20, illustrating the scale of the refueling effort required.

NASA's Artemis program also creates a deadline for crew-capable systems. The agency plans to launch Artemis III in mid-2027, when its Orion crew capsule is expected to dock with Ship in Earth orbit. By Artemis IV in 2028, Ship must be ready to support astronauts traveling to the lunar south pole. NASA has also indicated that Blue Origin's Blue Moon lander could serve on Artemis III or Artemis IV if Starship is not ready.

Meanwhile, the October 1 Transporter-18 rideshare mission carried three experimental payloads aimed at solving technical problems for orbital data centers, according to Payload. The projects investigate laser-based power transmission, artificial intelligence computing in orbit, and the transfer of energy between spacecraft.

Cowboy Space's Reason-1 is designed to test whether solar power can be transmitted to Earth using an infrared laser. The company hopes to attempt a demonstration as soon as late October, targeting a ground test area measuring 10 to 20 meters across and aiming to deliver 30 to 100 watts. Its planned Reason-2 mission, targeted for the first half of 2027, is expected to use the same laser technology to transmit data from H200 graphics processing units.

Google's Project Suncatcher is testing whether artificial intelligence chips can operate reliably in orbit using solar power. Developed with Planet Labs, the refrigerator-sized satellite carries four Trillium tensor processing units and approximately 1 kilowatt of solar power. According to Payload, Google reported that ground tests showed the chips could withstand radiation equivalent to five years in orbit, although occasional silent errors and overheating remain challenges.

Google's research envisions future satellites carrying 50 to 100 kilowatts of computing capacity and communicating through laser links. Its analysis estimates that, if launch costs fall to $200 per kilogram, putting a kilowatt of solar power into orbit could cost about $810 annually. The company suggested that this level could become possible by the mid-2030s if Starship reaches approximately 180 launches per year.

The third Transporter-18 experiment, Star Catcher's Protostar, is intended to demonstrate power transfer between spacecraft. The system will deploy a CubeSat and direct measurable energy toward its commercially available solar panels, testing technology that could help supply electricity to orbital computing systems.
