SpaceLocker: Transforming Access to Orbit with Shared Satellite Missions

French startup SpaceLocker has launched its first satellite mission, "Out of the Box," introducing a shared model for space missions that reduces costs and speeds up access to orbit. By allowing multiple payloads to operate on a single satellite, the company aims to make space more accessible, efficient, and sustainable for various users across Europe.

A fast-growing French startup is changing how companies reach orbit. SpaceLocker has launched its first fully owned satellite mission and officially entered the ranks of satellite operators.

The mission, called Out of the Box, marks a major step for the company. It also signals a shift in how space missions can be built, shared and managed.

The announcement comes just one year after SpaceLocker completed its first in-orbit mission, showing rapid growth in a complex industry.

A shared model for space missions

SpaceLocker is introducing a new way to send technology into space.

Instead of one satellite serving one customer, the company allows multiple payloads to share a single satellite. This shared model reduces costs and speeds up access to orbit.

The Out of the Box mission uses a 16U CubeSat that carries five different payloads from European customers.

This approach allows companies to launch their technology without building a full satellite.

Faster, cheaper and more efficient access to orbit

The company says its model delivers clear benefits.

Access to orbit can be twice as fast compared to traditional missions. Costs can be reduced by up to three times, and environmental impact can drop by as much as 40 percent.

These improvements could open space access to a wider range of users, including startups and research groups.

SpaceLocker’s CEO, Théophile Lagraulet, said the goal is to simplify the process.

He compared the model to cloud computing, where shared systems replace individual infrastructure.

A plug-and-play system for satellites

At the center of SpaceLocker’s platform is a universal space port.

This system works like a USB port for satellites. It allows different payloads to plug into the same platform without complex redesigns.

Customers build their own payloads and connect them to the satellite. SpaceLocker then handles the rest of the mission, including integration, launch and operations.

This process removes many of the barriers that have made space missions slow and expensive.
