This paper proposes solid propellant microthruster
array (SPMA) as an interesting choice for pico- and nanosatellites.
can provide a maximum of 1 mN thrust with 5 [micro]N thrust resolution.
A microwave microplasma microthruster
(3MT) design is discussed here to present a printable thruster that is simple, cost-effective, and light weight.
In contrast, Lozano's microthruster
design adds little to a satellite's overall weight.
in El Segundo, Calif., says the microthruster
design stands out among satellite propellant systems for its size and low power consumption.
It has the same size and mass as its predecessor but carries fewer mirrors (845) to accommodate two microthruster
nozzles and 31 optical retroreflectors that enable tracking by the International Satellite Laser Ranging Network.
This year, Hoffman's team made microthruster
nozzles for positioning satellites with a propulsion-induced nudge that Cox calls the "gnat sneeze."
Micronozzles, resonant beam structures, piston valves, and arrays of high aspect ratio structures have been fabricated for space microthruster
Small devices that emit neutrons could also be used as 'microthrusters
in miniature spacecraft', said the team
Other possible roles include pressure and acceleration sensors and satellite microthrusters
