Advanced NEXT Ion Propulsion System

Advanced NEXT is a NASA-led, high-thrust-to-power gridded-ion propulsion system derived from the NEXT-C flight design. A 2025 NASA conference paper reports 330 mN demonstrated thrust at an 8.2 kW-class system integration test, 2,500–3,400 s specific impulse across the throttle table, and 67% maximum thruster efficiency; development and life/qualification work remain ongoing. This record describes the propulsion system, not a spacecraft installation.

Lineage
  • Note
    Advanced NEXT modifies the NEXT-C flight design's discharge cathode, ion optics, and power-processing unit to increase thrust-to-power capability without significantly changing mass or volume.

    Note
    The NASA NEXT-C source provides the exact predecessor's flight-design identity and keeps the Advanced NEXT lineage edge distinct from NEXT-C's own DART flight heritage.
