Transporter-18 to Launch 130 Payloads from Vandenberg

SpaceX is preparing the Transporter-18 rideshare mission for liftoff from Vandenberg Space Force Base in California. The Falcon 9 rocket will carry 130 small satellites, among them two methane-monitoring spacecraft for GHGSat and the first satellite ever built by Canada's NordSpace.

Transporter-18 is slated to launch on 2026-10-01, with a backup window on 2026-10-02. The mission will fly from Space Launch Complex 4E aboard a Falcon 9, delivering 130 payloads to orbit. Forty-one of those payloads are designed for later separation, and two spacecraft incorporate reentry vehicles.

GHGSat's latest pair, C18 and C19—named Eleanor and Aidan—were constructed by SFL Missions in Toronto using the NEMO platform, each massing about 15 kilograms. The company specialises in tracking methane leaks from orbit. Its previous pair, built by Spire Global and flown on Transporter-17, recorded initial methane detections within weeks. The two new satellites are expected to separate roughly 55 minutes after liftoff.

NordSpace's debut satellite, Terra Nova, serves as a dual-use defence and commercial demonstrator, assembled at the company's Space Systems Lab in Markham, Ontario. The spacecraft uses an in-house platform, propelled by an electric thruster, and carries a camera with an NVIDIA processor that analyses images on board. This setup enables it to track objects in space and detect wildfires. Berlin-based launch services provider Exolaunch arranged its flight, and Terra Nova will be released about four minutes after the GHGSat satellites.

Two further Canadian CubeSats, Ex-Alta 3 and PRESET, could also be aboard Transporter-18, though their inclusion is not yet certain. Both are financed through the Canadian Space Agency's CubeSats Initiative in Canada for STEM (CUBICS) and have been manifested by Exolaunch under a CSA arrangement. PRESET's official launch date is listed as 2027, suggesting it may be reassigned to a later flight.

Rideshare missions like Transporter-18 drastically reduce the cost of reaching orbit, giving startups and national programmes an affordable path to test hardware that can later be adapted for lunar exploration. NordSpace's electric propulsion and on-board AI image processing are examples of technologies that lunar orbiters or landers could eventually use. GHGSat's persistent methane monitoring strengthens Earth-system data, which supports sustainable space policy. The Canadian Space Agency's use of commercial rideshare for its CUBICS CubeSats also illustrates how governments leverage these flights to advance space technology.

SpaceX's Falcon 9 rocket has become a workhorse for small satellite launches from Vandenberg's Space Launch Complex 4E, a site that has hosted numerous rideshare flights under the Transporter programme.

A backup launch opportunity is reserved on 2026-10-02.
