We're building the mobility infrastructure for the next generation of space. Safe, scalable, and sustainable propulsion technologies enabling resilient operations across commercial, institutional, and defense missions.
As orbital operations become increasingly dynamic and mission-critical, propulsion can no longer be an afterthought. We are building the next generation of space mobility solutions that enable satellites to maneuver, adapt, and operate efficiently throughout their entire lifecycle. By combining sustainable propellants, rapid manufacturability, and mission-focused design, we help unlock a safer, resilient, more agile, and more accessible future in space.
Our product family -WaterCube, WaterCube+, and OrbitRev - is redefining in-space mobility through sustainable propulsion technologies and mission support services. Designed to streamline spacecraft deployment and operations, our solutions reduce integration barriers, accelerate time-to-orbit, and unlock greater operational flexibility for commercial, institutional, and defense missions alike.

WaterCube is a sustainable water-based propulsion system for CubeSats and SmallSats, designed to deliver reliable in-space mobility with unmatched operational simplicity. Leveraging non-toxic propellant, additive manufacturing, and a modular architecture, WaterCube enables orbit raising, station keeping, collision avoidance, and deorbiting while reducing integration effort, testing complexity, and mission risk.
The world's first dual-mode water-based propulsion system, combining hydrolytic and electrothermal propulsion in a single architecture. Designed to unlock higher performance and mission flexibility, WaterCube+ delivers sustainable in-space mobility for the next generation of commercial, institutional, and defense spacecraft.
OrbitRev is a mission planning platform that maximizes the value of satellite propulsion systems throughout their lifetime. By combining orbital mechanics with high-fidelity propulsion models, it enables accurate maneuver design, simulation, and execution. The platform optimizes fuel consumption, extends mission lifetime, increases payload availability, and improves return on investment.

About Capsule
Every industry has a moment when the questions in the room start to change. For years, satellite propulsion has forced engineers into an uncomfortable trade-off: choose performance, and accept a longer, costlier path to flight โ or choose speed, and accept a system that compromises on what the mission actually needs in orbit. At the 40th Annual Small Satellite Conference in Salt Lake City this August, it became clear that the industry is done accepting that trade-off.
๐๐ก๐ซ๐๐ ๐๐๐ฒ๐ฌ, ๐๐ง๐ ๐๐๐๐ฎ๐ซ๐ซ๐ข๐ง๐ ๐๐ฎ๐๐ฌ๐ญ๐ข๐จ๐ง
From August 24 to 26, our CEO Francesco Marino represented Capsule Space at the ITA Pavilion inside the Salt Palace Convention Center, meeting with the system integrators, operators, and investors who are shaping the next generation of small satellite constellations. Conversation after conversation, a pattern emerged. Nobody was asking whether green propulsion was a good idea. They were asking something more specific โ and more demanding.
Can it scale across a constellation, not just a single spacecraft? Can it be trusted to perform reliably once it's in orbit, with no second chances? And can it be tested and validated fast enough to keep pace with today's compressed satellite programs?
Scalability. Reliability. Speed of testing. These aren't abstract wishes โ they are the practical constraints that decide whether a propulsion system ever makes it onto a real mission. And they are the exact problem WaterCube and WaterCube+ were built to solve.
๐๐ฎ๐ข๐ฅ๐ญ ๐๐จ๐ซ ๐ญ๐ก๐ ๐๐จ๐ง๐ฌ๐ญ๐ซ๐๐ข๐ง๐ญ๐ฌ ๐๐ก๐๐ญ ๐๐๐ญ๐ฎ๐๐ฅ๐ฅ๐ฒ ๐๐๐ญ๐ญ๐๐ซ
WaterCube is our green, water-propellant propulsion system, designed from the outset around a simple premise: a satellite platform shouldn't have to choose between doing propulsion right and doing it fast. Water propellant means a system that is safer to handle, easier to integrate, and free of the regulatory friction that comes with more hazardous, conventional propellants โ without giving up the performance a real mission needs once it reaches orbit.
That combination is what turned heads in Salt Lake City. It is also what has carried WaterCube from a ground-tested concept to a flight-proven milestone in a remarkably short window. This October, WaterCube will fly aboard a Falcon 9 launch for its In-Orbit Demonstration (IOD) โ the moment a propulsion system stops being a promising idea on a test bench and becomes proven technology in the environment that actually counts.
๐๐ก๐ ๐๐จ๐ซ๐ค ๐๐๐ก๐ข๐ง๐ ๐ญ๐ก๐ ๐๐จ๐ง๐ฏ๐๐ซ๐ฌ๐๐ญ๐ข๐จ๐ง๐ฌ
None of what happened at the ITA Pavilion was possible without the months of work that preceded it. Every question Francesco fielded, every technical conversation, every moment of interest from a potential partner or investor, was built on the quiet, exacting work of the engineers and technicians who have spent the past year taking WaterCube through design reviews, qualification testing, and flight model integration.
That is the part of deep tech that rarely makes it into a headline: the iteration, the testing cycles, the small adjustments that compound into a system ready to fly. Salt Lake City was where that work became visible to the wider industry. October, with the IOD, is where it becomes proof.
๐๐ก๐๐ซ๐ ๐๐ ๐๐จ ๐
๐ซ๐จ๐ฆ ๐๐๐ซ๐
The response in Salt Lake City confirmed something we already believed, but it's different to hear it validated directly by the people who will decide what flies on the next generation of satellite platforms: the market is actively looking for propulsion that scales, that can be relied on in orbit, and that doesn't force a mission timeline to bend around a testing bottleneck.
We built WaterCube for exactly that market. And with WaterCube+ already in development under an ESA contract, and WTC-6DOF and OrbitRev advancing multi-directional control and mission software, the roadmap ahead is built on the same principle: propulsion should meet the mission where it is, not the other way around.
If you're building a satellite platform and propulsion is still an open question in your design, we'd like to talk โ ideally before your next design review.

In the frame of the ESA investor forum in December 2024, we won the sustainability pioneer award for the best pitch on sustainable space technologies
The road to START Summit Milano pitch event is a student-organised competition for early stage startups. We won the event twice, which allowed us to take part with a free booth to the San Gallen START Summit, one of the largest early-stage startup events in Europe.
ESA has awarded a 600k Euro worth TDE contract for the development of a disruptive propulsion system (WaterCube+) for cubesats and smallsats. We are the Prime Contractors of the Consortium, with Politecnico di Milano DAER SPLab and ReActive - Powder Technology srl, as Subcontractors.
The Encubator grant (25k Eur) has been awarded by Camera di Commercio di Milano to further develop the WaterCube solution for sustainable space mobility. It allowed us to attend TEF accelerator and improve our awareness in the sustainability field.
The MUSA grant (25k Eur) has been awarded by Regione Lombardia to further develop the WaterCube solution for sustainable space mobility.
We successfully completed ESA BIC Milano incubator sponsored by ESA and Regione Lombardia. It allowed us to further mature the development of WaterCube from a simple proof of concept to an actual flight model.
