Editing Resistojet rocket (section)

== Advantages ==
Many satellite missions necessitate an ability for minor alterations in trajectory even after the craft has been inserted into orbit. Most satellites use [[Monopropellant rocket|monopropellant]] rocket motors or [[cold gas thruster]]s for such orbital adjustments. Both methods, however, suffer from some limiting drawbacks: Hydrazine, the most commonly used monopropellant, is highly expensive and due to its volatile nature unsuitable for smaller satellites that are sent to space as secondary cargo. Cold gas thrusters, while utilizing relatively cheap, inert and therefore "safe" gasses like nitrogen, suffer from low [[specific impulse]] in comparison to monopropellant motors. Resistojets are designed to bridge the gap between these two methods of propulsion, offering the safety of an inert propellant coupled with specific impulse nearing that of hydrazine.<ref>{{Cite journal|last=Gibbon|first=Dave|date=2002|title=The Development of a Family of Resistojet Thruster Propulsion Systems for Small Spacecraft|url=https://digitalcommons.usu.edu/cgi/viewcontent.cgi?referer=&httpsredir=1&article=1769&context=smallsat|journal=Surrey Space Centre, University of Surrey|volume=|pages=1|via=}}</ref>
