Researchers at the University of Stuttgart have developed a new atmosphere-breathing electric propulsion system designed to enable satellites in Very Low Earth Orbit to stay in orbit indefinitely without carrying conventional propellant.[^1]

Francesco Romano, a researcher at the University of Stuttgart, developed the engine which scoops atmospheric gases, converts them into plasma, and expels them to counteract drag.[^2]

The work was filed mid-day on September 28, 2026.

In unrelated research filed the same day, researchers at China's Xihang University conducted an exergy analysis of a PVT-assisted air-source heat pump system for cold climates.[^3]

The tested PVT-assisted heat pump system achieved exergy efficiencies ranging from 41.2% to 49.3% across ambient temperatures of -10°C to 10°C.[^4]
