New Satellite Engine Could Use Earth’s Atmosphere as Fuel To Stay in Orbit Indefinitely

Summary by Sci Tech Daily
A satellite engine that uses atmospheric gases as fuel shows promise in laboratory tests and modeling, but its performance on a mission remains unproven. Choosing an orbit for a satellite involves balancing benefits and drawbacks. Very Low Earth Orbit (VLEO), which spans roughly 100 to 450 km (62 to 280 miles) above Earth, offers several [...]

Satellites in low orbits have a massive problem with atmospheric friction. A new concept for plasma engines could now solve this challenge in an unexpected way and drastically prolong operation. read more on t3n.de

A new satellite engine that uses atmospheric gases as fuel presents promising results in laboratory tests. The technology, developed by Francesco Romano during his doctorate at the University of Stuttgart, can allow satellites to remain in low Earth orbit indefinitely, without the need for a conventional propellant supply. Development of the Roman propulsion engine investigated a system known as electric propulsion that breathes atmosphere (ABEP…
