The invention discloses a microwave detonation dual-mode space thruster. The microwave detonation dual-mode space thruster comprises a propellant supply system, a high-thrust propelling module and a micro-thrust propelling module, wherein the high-thrust propelling module and the micro-thrust propelling module are sequentially and coaxially arranged from inside to outside; the high-thrust propelling module comprises an injector, a plasma ignition combustion-supporting device, a detonation chamber, an exhaust nozzle and the like. The micro-thrust propulsion module comprises a microwave supply system, a magnetic pole, a gas collection cavity, a discharge chamber and a grid electrode; the microwave supply system comprises a microwave connector and an antenna; the antenna is a cylindrical antenna, and a convolution cavity is formed between the antenna and the magnetic pole; outer-layer electrons in electrical substance molecules in the convolution cavity do convolution motion in the convolution cavity, and when the convolution angular frequency is equal to the microwave frequency, resonance occurs. The microwave discharge technology, the plasma combustion-supporting technology and the pulse detonation combustion technology are fused, efficient and convenient switching of working modes is achieved through circuit regulation and control, the thruster can meet the strict requirements of large thrust, high specific impulse, long service life and the like, and the thruster can be applied to diversified space tasks.
