Spanish aerospace firm Kreios Space has officially announced its upcoming maiden demonstration of air-breathing electric propulsion (ABEP) technology in very low Earth orbit (VLEO), according to SpaceNews. The announcement, made on Aug. 4, outlines a mission intended to validate the company's proprietary propulsion systems while integrated into a satellite bus manufactured by NanoAvionics.
The demonstration aims to operate at the extreme altitudes characteristic of VLEO, where thin atmospheric gases are gathered and ionized to generate thrust. By utilizing this process, Kreios Space intends to sustain satellite operations in orbits that typically suffer from rapid orbital decay due to increased atmospheric drag.
### Technical Mission Parameters
| Specification | Detail | | :--- | :--- | | Announcement Date | Aug. 4 | | Technology | Air-breathing electric propulsion (ABEP) | | Satellite Bus Provider | NanoAvionics | | Operational Environment | Very low Earth orbit (VLEO) |
NanoAvionics, a subsidiary of Kongsberg, will provide the standardized bus to serve as the host platform for the experiment. The partnership signifies a shift toward utilizing commercial-off-the-shelf satellite infrastructure to accelerate the development of specialized propulsion capabilities that could theoretically allow satellites to maintain operational altitudes without traditional onboard propellant storage.
## Why It Matters
The ability to operate reliably in VLEO presents a transformative prospect for Earth observation and high-resolution imaging sectors. Satellites currently operating in higher orbits must compromise on sensor resolution due to distance; operating in VLEO allows for significantly improved data capture. If Kreios Space successfully validates its AEP system, it may lower the barriers to entry for persistent low-altitude satellite missions. This capability effectively reduces the need for heavy, volatile propellant loads, potentially allowing for longer mission life cycles and enhanced maneuverability in an increasingly crowded orbital environment where collision avoidance is mandatory.
