About
The BHT-20K is Busek’s highest power thruster to date, offering over 100 times the power of the company’s first Hall thruster. Using an innovative 2.8 cm center-mounted cathode and a highly mass-efficient magnetic circuit design, the BHT-20K delivers outstanding specific impulse and thrust in a lightweight, compact package. Tested at the Arnold Engineering Development Center (AEDC) and NASA Glenn Research Center, it has demonstrated throttling from 5 kW to 22 kW input power, targeting high-power missions to the Moon, Mars, Venus, and beyond.
