The Air-Breathing Helicon Plasma Thruster, a thruster utilizing ambient air which is suggested to support small spacecraft on very low Earth’s orbits, has been tested successfully. Using a retarding field energy analyser and Langmuir probe, the specific impulse have been confirmed for operating conditions of 1.5 mg·s −1  of air, 50 mPa gas pressure, 120 W of radio-frequency forward power at 13.56 MHz, and a maximum axial magnetic field of 200 G at the 200 km attitude. The inductively coupled plasma and ion beam formed have been characterized axially, and the measured beam velocity is about 1100 km·s −1  for these conditions.
