Space-technology innovator NewOrbit Space has unveiled AURA, a breakthrough in electric-propulsion technology designed to sustain operations in ultra-low Earth orbit (ULO). This next-generation propulsion engine embodies the company’s vision to open new frontiers in satellite operations and orbital infrastructure. By merging flexible architecture, multi-propellant capability and exceptional energy efficiency, AURA represents a decisive step toward enabling satellites to operate closer to Earth than ever before by unlocking faster data transmission, lower latency and enhanced imaging capabilities.
AURA Propulsion System
The AURA propulsion system is a unified architecture engineered specifically to address the demanding challenges of very low Earth orbit (VLEO) missions. At its core lies the AURA-X engine, a xenon-driven propulsion system capable of delivering high specific impulse performance with unmatched stability and reliability. The AURA-A variant introduces an air-breathing propulsion concept that can utilize atmospheric particles with primarily nitrogen and oxygen as propellants. This dual-configuration capability marks a groundbreaking advancement in propulsion adaptability, allowing spacecraft to switch between propellant types depending on mission requirements and orbital environment. The system integrates all essential components including thruster, cathode, propellant-management modules and onboard control electronics into a single compact unit. This integrated design not only simplifies system architecture but also boosts overall efficiency. Laboratory tests indicate that the xenon-powered AURA-X achieves a specific impulse of up to 4,500 seconds, while the air-breathing AURA-A demonstrates performance levels reaching approximately 8,700 seconds, setting new standards for high-efficiency propulsion.
The AURA propulsion architecture can be reconfigured for xenon propellant, atmospheric intake, or future propellant options without the need for extensive hardware modifications. This future-proof design reduces lifecycle costs and ensures long-term adaptability for evolving mission needs. Operating in ultra-low Earth orbit presents unique aerodynamic and environmental challenges particularly the continuous drag caused by residual atmospheric particles. AURA’s high-efficiency thrusters provide the necessary thrust to compensate for this drag, ensuring sustained orbital stability and longer mission durations even in this dynamic regime. By enabling satellite operations in lower orbits, spacecraft can naturally de-orbit faster at the end of their lifecycle, drastically reducing the buildup of space debris. This supports the growing international push toward responsible orbital behavior and debris mitigation. Satellites equipped with AURA can capture higher-resolution imagery, deliver low-latency communications and enable direct-to-device connectivity for next-generation broadband and IoT applications. The system also opens new avenues for atmospheric sensing, climate monitoring and Earth science missions enhancing the overall value of space-based data services.
The AURA propulsion platform is designed for a wide range of orbital missions, offering versatility across scientific, commercial and government applications. For Earth observation missions, AURA empowers satellites to capture unprecedented levels of detail from ultra-low altitudes, improving spatial resolution and data quality. In communications, its low-latency advantage supports emerging direct-to-device connectivity services, helping bridge the digital divide across underserved regions. The system is equally suited for sustainable satellite constellations that prioritize rapid deorbiting, low-environmental impact and extended operational lifespans. The adaptable design allows mission planners to configure propulsion systems for varying orbital altitudes, ensuring optimal performance for both short-term technology demonstrators and long-term infrastructure networks.
