Telesat books all 225 Lightspeed satellites on SpaceX rockets
What happened
LightShed's Walter Piecyk asked Goldberg directly whether Telesat's expanded launch manifest is contracted, citing SpaceX having "stopped taking third-party bookings beyond '28." Goldberg: "to launch the 225 satellites, we estimate we need 15 rockets. We already have 14 under contract with SpaceX." Three previously surplus rockets held against the original 156-satellite plan were absorbed by the 69-satellite expansion, leaving a one-rocket gap; "we've been in touch with our friends at SpaceX. They've agreed to make that rocket available to us. We're getting the launch services agreement in place." He committed to all 225 satellites being launched by end-2028 and gave no non-SpaceX alternative, calling Falcon 9 "the right launch vehicle for Lightspeed" on reliability and cadence grounds. Separately, on whether spectrum could be added to the satellites: "these first 225, we're done… the design is done, the hardware has been ordered and satellites are already at MDA's new factory," with band additions or hosted payloads possible only on a next-generation Lightspeed.
Read-across for SES
The launch-bottleneck thread's core claim is that global launch supply, not manufacturing or spectrum, gates every non-SpaceX constellation through ~2028 — including SES's own meoSphere and mPOWER manifests. This is the first primary-text datapoint that separates two things the desk had been treating as one: SpaceX's booking freeze covers commercial *rideshare* (Transporter/Bandwagon), and does not currently extend to dedicated Falcon 9 sales to a rival Western LEO operator — SpaceX agreed to sell a 15th rocket to Telesat inside the frozen window. That is a more permissive supply picture than the thread has assumed, and it is worth SES modelling against its own 2029 meoSphere launch requirement. The offsetting read is dependency: a 225-satellite allied-sovereign constellation carrying Canadian military Ka traffic is 15-for-15 dependent on a single US commercial provider, with no hedge named — the same structural exposure Europe's IRIS² sovereignty argument is built to avoid, now visible in a NATO-ally program. The thread's falsifier (a non-SpaceX provider flying ≥1 dedicated LEO-constellation mission/month at ≤2x F9 rideshare rates) remains untripped and, on this evidence, is not close.
As the brief filed it
[AGE: 18h] Telesat confirms all 225 Lightspeed satellites launch on SpaceX Falcon 9 — 14 of 15 rockets contracted, SpaceX agreed to sell the 15th — first primary evidence that SpaceX's rideshare booking freeze past 2028 does not extend to dedicated launches for a rival Western constellation.
