HyPrSpace (France) and Tumbleweed (Austria) Sign Strategic Partnership to Deliver Dedicated European Microgravity Launch Services

June 8, 2026 — HyPrSpace, a French industrial company commercializing suborbital and orbital launch services through a family of launchers powered by patented technology, and Tumbleweed, a European company developing a streamlined flight service for microgravity research and manufacturing payloads, announce the signing of a strategic partnership.

This new milestone comes as Tumbleweed has just made history in Austrian spaceflight with Oasis Alpha, the country’s first commercial satellite.

This agreement frames the collaboration between the two companies to explore new opportunities in the fields of scientific research and microgravity manufacturing. It notably aims to combine the launch capabilities developed by HyPrSpace with Tumbleweed’s payload solutions and flight platforms.

A Partnership to Develop Sovereign Suborbital Services Dedicated to Microgravity

HyPrSpace and Tumbleweed aim to implement competitive, high-frequency suborbital launch services to meet the growing demand of the microgravity market.

Tumbleweed will leverage its expertise in microgravity missions, a field at the core of its business. The company is notably developing Pod, its containerized system designed for scientific experiments and equipment, as well as Oasis, its low-cost orbital platform built to provide in-orbit operations and return to Earth.

For its part, HyPrSpace will work on developing suborbital services for the systems developed by Tumbleweed through its Baguette One launcher. This complementarity paves the way for the development of offerings tailored to the specific needs of hosted missions.

“We are thrilled to take this new step with Tumbleweed. This partnership aims to approach launch not only as access to space, but also as a service designed around the needs of customers and their payloads. By leveraging Tumbleweed’s microgravity expertise, we want to develop with Baguette One sovereign European suborbital solutions adapted to the needs of scientific research and space manufacturing,” says Sylvain Bataillard, CSO and Co-founder of HyPrSpace.

Preparing the Orbital Deployment of Tumbleweed’s Free-Flyer Vehicles

Beyond suborbital services, this partnership paves the way for collaboration around the future orbital deployment of Tumbleweed’s free-flyer vehicles using launchers designed by HyPrSpace.

This new milestone marks the beginning of an operational collaboration between the two companies, encompassing missions ranging from suborbital to future orbital services.

“This collaboration with HyPrSpace marks a new step in the development of our microgravity flight services. To make these services more accessible, it is essential to think about the payload, the flight, and the launch together. By combining HyPrSpace’s launch capabilities with our Pod and Oasis solutions, we aim to explore a more integrated and sovereign approach to microgravity missions, from suborbital flights to the future orbital deployment of our free-flyer vehicles,” says Guillaume Brault, Co-founder and CTO at Tumbleweed.

About HyPrSpace

A French industrial company, HyPrSpace commercializes suborbital and orbital launch services through a family of launchers powered by patented hybrid propulsion technology.

This disruptive, inherently dual-use innovation provides a concrete response to Europe’s space and defense ambitions, through robust, competitive, and sovereign solutions.

The technology has been successfully tested during three full-scale engine test campaigns at the DGA Missile Testing facilities in Gironde.

The first liftoff will take place from metropolitan France, marking a historic first in the French space adventure.

About Tumbleweed

Founded in 2024 and based in Vienna with an office in Delft, Tumbleweed develops plug-and-play space logistics solutions, making access to space as easy as mailing a package.

Through its Pod technology — a modular payload container — and Oasis, an autonomous orbital platform capable of returning experiments to Earth, the company aims to reduce space access lead times from several years to just a few months.
