Telesat slips first Lightspeed launch by three months

Telesat's first Lightspeed satellites will fly three months late, CEO Dan Goldberg told analysts on October 29, conceding that the launch schedule for the Canadian operator's low Earth orbit constellation "has slipped."

The delay sits with the hardware, not the ride. The first two Lightspeed craft — described as "pathfinder" satellites — are being built by fellow-Canadian firm MDA Space, and they aren't ready. That knocks on to Telesat's reserved slots on SpaceX rockets, with the two pathfinders now expected to launch around June 2028.

The money already committed is considerable. Telesat said that as of September 30 it had invested C$3.1 billion (€1.9 billion) into Lightspeed.

What does the delay mean for the constellation plan?

The arithmetic of the manifest stays intact, just shifted. Telesat has 14 launches booked with SpaceX and will need one more to loft the initial 156 satellites required for the working fleet. The full constellation will eventually number 225 spacecraft.

Once the pathfinders are up, Telesat expects SpaceX to launch batches of 15 Lightspeed satellites every three weeks through mid-to-late 2028. It's a demanding cadence — roughly five satellites a week, sustained for months — and everything depends on those first two birds flying on time.

A three-month slip on a programme of this scale is modest. It's also the second reminder in a year that constellation schedules answer to manufacturers and launch providers as much as to operators.

How did the GEO business perform?

Telesat reported results for the three and nine months ended September 30 alongside the launch news, and the legacy geostationary business is doing what legacy businesses do: shrinking in an orderly fashion.

Quarterly revenue came in at $81 million, down 20 percent — $20 million — from the same period a year earlier. The GEO segment accounted for $79 million of that, a 21 percent drop, or $22 million, versus the third quarter of 2025.

The company attributed the decline to specific, identifiable causes rather than general market drift:

• Non-renewal of a broadcast contract in 2025
• Reduced contracted capacity for a broadcast customer in 2026
• Reduced service to a North American broadband customer
• Removal from service of certain geostationary satellites

Goldberg put a steady face on it. "In our GEO business, we continue to be laser-focused on maximizing the revenue and cash flow from our existing GEO satellite fleet while at the same time taking a highly disciplined approach to cost management," he said.

"Our GEO business has performed consistent with our expectations in the first nine months of the year, and we are reiterating our 2026 GEO revenue [guidance]," the CEO added.

Is the guidance credible?

Reiterating guidance while revenue falls 20 percent looks odd until you read the fine print: the declines came from known contract events, not unexpected churn. Telesat expected the broadcast non-renewal and the capacity reduction. Managing the decline, rather than reversing it, is the stated strategy — milk the GEO fleet for cash while Lightspeed absorbs the capital.

That makes the C$3.1 billion already sunk into Lightspeed the real story. The GEO business funds the pivot; the LEO business is the pivot. A three-month pathfinder delay doesn't threaten that logic, but it does compress the 2028 launch window in which Telesat must execute 15-satellite batches every three weeks to build the initial 156-craft fleet.

The next checkpoint is concrete: MDA Space delivering the two pathfinders in time for a June 2028 SpaceX launch. Miss that, and the every-three-weeks cadence — and the full 225-satellite end state — slides with it.
