IN-space Propulsion
Your Mission Doesn't End At Orbit.
Once your satellite reaches orbit, the real mission begins. Vaya's in-space propulsion systems provide the sustained mobility, rapid response, and mission flexibility to keep your spacecraft exactly where it needs to be — for the full duration of your mission.
01
ORBIT RAISING
Reach your final operational altitude after launch separation.
02
DEBRIS AVOIDANCE
Rapid maneuvers on short notice, followed by return to station.
03
LIFESPAN EXTENSION
Repeated orbit maintenance to keep your spacecraft operational longer.
04
SAFE DEORBIT
Controlled end-of-mission deorbit in compliance with debris mitigation requirements.
Non-toxic
PROPELLANT CLASS
Non-explosive, storable propellants
ESPA+
STANDARD FITTING
Adapts to ESPA and custom interfaces
∞
RESTART CAPABLE
Reliable multi-burn mission profiles
<5 mo
CLEAN SHEET TO HOT-FIRE
Tailored to your mission, fast
Capabilities
Affordable. Adaptable. Reliable.

SUSTAINED MOBILITY
Long-term storable propellants and robust restart capability provide flexible mobility for the entire lifespan of your spacecraft. Maneuver within your orbit on demand, repeatedly, without range constraints.

DEBRIS & THREAT AVOIDANCE
High thrust enables rapid avoidance maneuvers on short notice. A second burn returns your spacecraft to its original position — minimizing disruption to your mission timeline and operations.

ORBIT RAISING & STATION KEEPING
Raise your orbit after launch separation to reach your final operational altitude, or maintain your station against atmospheric drag for extended mission durations. Precise throttle control throughout.

END-OF-MISSION DEORBIT
Controlled deorbit burns ensure your spacecraft complies with debris mitigation regulations and international guidelines — protecting the orbital environment without requiring a separate propulsion system.

Mission Profiles
From Last-Mile Delivery to Interplanetary Transfer
SMALL SATELLITES
CubeSat and SmallSat Mobility
Compact, lightweight propulsion designed for CubeSat and SmallSat form factors. Provides the orbital flexibility larger satellites take for granted — orbit maintenance, collision avoidance, and controlled deorbit — in a package sized for small missions.
ESPA COMPATIBLE - STORABLE PROPELLANTS - LIGHTWEIGHT
COMMERCIAL OPERATIONS
CONSTELLATION SUPPORT
Maintain precise orbital slots in large constellations. Repeated orbit adjustments, phasing maneuvers, and inter-plane transfers — with reliable restart capability and long-duration storability to keep your constellation precisely aligned.
MULTI-BURN - PRECISION PHASING - LONG DURATION
DEFENSE & NATIONAL SECURITY
RESPONSIVE SPACE
Rapid repositioning, evasive maneuver capability, and threat avoidance for national security spacecraft. Non-explosive propellants mean safer integration, storage, and launch processing — without compromising performance when it counts.
RAPID RESPONSE - THREAT AVOIDANCE - NON-EXPLOSIVE

TAILORED TO YOUR MISSION
Scalable, Custom Propulsion - Fast
Every element of Vaya propulsion — from system design through manufacturing — is built for scalability. Given a spacecraft size and mission profile, we model the required performance, engineer and optimize a design, and additively manufacture a propulsion system optimized specifically for your mission.
01
MISSION MODELING
We model your required performance — delta-v budget, thrust requirements, burn duration — based on your spacecraft and orbit.
02
DIGITAL DESIGN & OPTIMIZATION
Proprietary simulation tools model thousands of engine geometries, autonomously optimizing the design for your exact mission parameters.
03
ADDITIVE MANUFACTURING
3D-printed fuel grain from 99% recycled thermoplastic — non-explosive, manufacturable in custom geometries, and produced on-campus in Cocoa, FL.
04
HOT-FIRE & DELIVERY
Testing at our on-campus facility in Florida, then delivered to your integration team. From clean sheet to hot-fire in less than five months.
