Problem
Current satellite systems lack the maneuverability required for rapid on-orbit adjustments and relocation, limiting their responsiveness to dynamic mission needs and emerging opportunities in LEO, MEO, and cislunar space. Traditional propulsion systems often constrain a satellite's lifespan and operational flexibility due to limited delta-v capabilities.
Solution
Portal Space Systems offers the Supernova satellite bus, a 500 kg spacecraft engineered for exceptional maneuverability. Supernova's solar-thermal propulsion system delivers ultra-high delta-v, enabling rapid repositioning across a wide range of orbits, including LEO, MEO, and cislunar trajectories. This enhanced mobility allows operators to respond swiftly to tactical demands, optimize asset deployment, and extend mission lifecycles. The Supernova bus supports diverse payload configurations, providing a versatile platform for various space-based applications.
Target Audience
The primary target audience includes government and commercial satellite operators requiring responsive and highly maneuverable spacecraft for dynamic space operations.
