Marble Sat-1 to Fly Laser Downlink Terminal on First Mission

Earth observation operator Marble Imaging, satellite manufacturer Reflex Aerospace, and optical communications specialist Odysseus Space announced on October 21, 2026 a joint mission to deploy space-to-ground laser communications aboard Marble Sat-1. The spacecraft, named Morgana, is scheduled to launch in the first quarter of 2027 and will use optical downlink technology to accelerate data delivery for European Earth observation.

High-resolution Earth observation payloads generate large data volumes, and operators face throughput constraints when downlinking via conventional radio-frequency channels, which typically operate between 1 and 2 Gbps. Optical communications bypass these spectral limitations using narrow, interception-resistant optical beams that operate outside international radio spectrum licensing regimes. The deployment operationalizes concepts outlined by Odysseus Space on how laser communications resolve orbital data transfer bottlenecks to enable scalable space infrastructure.

Shifting to managed Laser Communication as a Service enables Marble Imaging to lower data retrieval costs by a factor of ten while securing high-volume data streams for civil monitoring and defense intelligence. The satellite platform, manufactured and integrated by Reflex Aerospace, recently passed flight qualification and vibration testing. The platform builds upon manufacturing lines supported by Reflex Aerospace's 50 million euro Series A funding and earlier demonstration partnerships between Marble Imaging and Reflex Aerospace.

The spacecraft carries Odysseus Space's Cyclops-DTE terminal, delivering transmission speeds up to 10 Gbps and daily throughput of at least 1 terabyte of imagery. The service is provided on a subscription basis with no upfront hardware expense and manages pass planning through to data delivery. It is supported by planned access to 50 optical ground stations within five years.

Leadership emphasized the dual throughput and security advantages of optical links. "Laser communication unlocks the downlink speeds needed for the massive data volumes of next-generation Earth observation satellites, while offering inherently more secure data transfer, critical in the current environment," stated Robert Hook, Chief Executive Officer of Marble Imaging.

Morgana serves as the pathfinder for Marble Imaging's planned constellation of more than 20 very high-resolution satellites delivering hourly planetary analytics. The companies position the mission as a step toward scalable space infrastructure that resolves conventional downlink bottlenecks while securing high-volume data streams for both civil monitoring and defense intelligence.

Following its early 2027 launch, Marble Sat-1 will conduct a six-month in-orbit demonstration phase before beginning commercial operations.
