Space Solutions Overview
Our solutions include “bolt on” propulsion modules as well as application-specific spacecraft capable of semi-autonomously performing entire missions.
Rapid Orbital Mobility Bus
- Parabilis’ Rapid Orbital Mobility Bus (ROMBUS) propulsion module provides high-impulse thrust for satellite translational maneuvers, and can be used for initial orbit insertion, rapid orbit rephasing, threat/collision avoidance, and targeted re-entry at the satellite’s mission end of life. The low-cost ROMBUS design consists of a safe, green hybrid propulsion system utilizing rubber (HTPB) or acrylic (PMMA) for fuel, and nitrous oxide (N2O) as an oxidizer. The basic configuration is a single, centrally located motor nested within the oxidizer tanks. Two cold gas thruster triads use the N2O as propellant for low-thrust maneuvers and attitude control to augment reaction wheels or to dump momentum from reaction wheels.
Orbital Cargo Return Tug
Parabilis is developing Orbital Cargo Return Tug (Orbital CaRT), a reusable, semi-autonomous orbital transport vehicle ideal for placing reentry capsules on a precise re-entry trajectory. This vehicle will have sufficient thrust and Delta-V capability to place a capsule with its cargo on a re-entry trajectory, re-boost to the original orbit, rephase and repeat the process with more cargo capsules. This system will enable the economical return of in-space manufactured goods in a timely manner and is also fully capable of performing a wide range of other common orbital maneuvers.
