TransMIT GmbH is working on the Atmosphere-breathing propulsion concept for over 15 years. The number of theoretical and experimental campaigns that has been performed in this time cover various thruster sizes and power ranges, compatible neutraliser designs, operation at Earth and Mars low orbit environmental gas compositions, investigations on relevance of the Atmosphere-breathing propulsion on-ground testing as well as trials of the orbital particle flow reproduction, finally system level global relationships to envelope design requirements and challenges were always amongst the topics of interest. This paper is the summary of company experience and lessons learnt together with current understating on challenges ABEP development introduces, requirements it sets and best at authors opinion ways to approach ABEP thruster technology selection and design.    «
