Kreios Space to Test Air-Breathing Propulsion in VLEO on NanoAvionics Satellite
Spanish startup Kreios Space announced on August 4th its intention to perform the first demonstration of its air-breathing electric propulsion (ABEP) system in a very low Earth orbit (VLEO). This test flight will utilize a satellite bus provided by NanoAvionics. The ABEP technology aims to leverage residual atmosphere in VLEO to generate thrust, potentially offering a more sustainable propulsion solution. VLEO, typically defined as orbits below 300 kilometers, presents unique challenges due to increased atmospheric drag. Kreios Space's technology seeks to address this by using the atmosphere itself as a propellant source. The demonstration is a significant step for the company in validating its innovative propulsion concept in a real space environment. Successful testing could pave the way for future VLEO missions that require precise station-keeping or maneuvering capabilities.
This planned demonstration by Kreios Space highlights the ongoing innovation in satellite propulsion systems, particularly for operations in very low Earth orbits. The ABEP technology, by utilizing atmospheric gases, presents a novel approach to propellant management and potentially reduces launch mass and cost. However, the increased atmospheric drag at VLEO altitudes necessitates robust station-keeping capabilities, and the efficiency and reliability of ABEP in sustained operation remain key areas for validation. The success of this demonstration could influence future mission architectures for Earth observation and communication constellations, especially as orbital debris mitigation and sustainable space operations become increasingly critical considerations over the next decade.
