SES Beams CEO Video Over Laser Link in meoSphere Pathfinder Trial
SES transmitted CEO Adel Al-Saleh's video over a bidirectional laser link from Rennes to a Mynaric terminal on K2's GRAVITAS satellite, validating optical tech for its meoSphere MEO network.
Networks & InfrastructureWhy it matters
- SES transmitted CEO video over a bidirectional laser link, announced November 5, 2026
- Link ran from Cailabs' ground station in Rennes, France, to a Mynaric CONDOR terminal on K2's GRAVITAS Mega-class platform
- Rocket Lab closed its acquisition of Mynaric in April, making the terminal hardware Rocket Lab's
- Thales Alenia Space supported assembly, integration, testing and operations; SES built the automation software
- The Pathfinder 1 team will next test longer link durations and higher speeds ahead of future Pathfinder missions for the meoSphere MEO constellation
The story
Satellite operator SES has transmitted video messages from CEO Adel Al-Saleh over a bidirectional laser optical link between a ground station in Rennes, France, and a payload in orbit, the company announced on November 5, 2026. The demonstration, branded Pathfinder 1, used a Mynaric CONDOR optical terminal in space and a Cailabs optical ground station on the ground.
The orbital end of the link flew on K2's GRAVITAS mission, which runs on K2's Mega-class satellite platform. SES designed, developed and operated the optical mission itself, and wrote automation software that made the demonstration possible. Thales Alenia Space handled system assembly, integration, testing and operations support.
One ownership detail matters for the supply chain. Rocket Lab completed its acquisition of terminal maker Mynaric in April 2026, so the optical hardware on this link is now Rocket Lab's. SES has effectively demonstrated a future procurement route through one of the space sector's most acquisitive primes.
Why the test matters for SES
The commercial point is not the video itself. It is the validation of optical, or laser, communications for SES's next-generation meoSphere network, a fleet of medium Earth orbit satellites now under construction. Radio-frequency links face spectrum constraints and interception risks; laser links offer high-capacity, narrow-beam transport that is harder to intercept and needs no spectrum licensing in the conventional sense.
SES called the test an important milestone in meoSphere's development. "The achievement validates a critical technology that will support future high-capacity, secure and flexible connectivity services," the company said in a statement.
SES framed the wider ambition in measured terms. "The successful demonstration reinforces SES's ability to design, develop and operate advanced optical communications technologies that will support the evolution of its meoSphere network," the operator stated. "By leveraging optical communications, meoSphere is expected to enable more flexible, resilient and secure data transport while supporting growing demand for high-capacity connectivity."
What does this change for customers?
Nothing immediately. No meoSphere service exists yet, and SES published no throughput figures, link durations or data volumes from the trial. What the test changes is confidence in the architecture: SES has shown it can close an optical link from its own payload to a commercial ground station in an operational setting, using automation software it built in-house.
Carmel Ortiz, SVP of MEO Programs at SES, positioned the result as evidence of method rather than a single stunt. "This Pathfinder 1 achievement validates our vertically integrated, iterative approach to developing next-generation space capabilities," Ortiz said. "Together with our partners, we have successfully and repeatedly transferred data between space and the ground, demonstrating the performance of optical communications in an operational environment. Each milestone brings us closer to realising the optical architecture that will help power our future meoSphere network, delivering greater flexibility, security, and capacity for our customers' most demanding connectivity requirements."
The word "repeatedly" is notable. Sustained, repeatable links, not one-off captures, are the hurdle that separates optical demonstrations from deployable network technology.
What comes next
The Pathfinder 1 team will continue testing with three stated goals:
- Extend link duration
- Push link speed and performance
- Feed results into future Pathfinder missions
Those follow-on missions will advance the optical networking technologies that SES intends to underpin the meoSphere constellation. SES has not published dates for the next Pathfinder flight or for meoSphere service introduction, so the timetable remains the open question as the program moves from validation toward build-out.
