Sienna Technologies, Inc, proposes to develop a robust, long life, catalytically ignited thruster that can perform multiple cold starts at low preheat temperatures (

Present and future NASA missions, including the Asteroid Redirect Mission and efficient cargo delivery to mars, require a substantial increase in lifetime for ion engines and Hall thrusters. This has ...

Ultra-high-temperature ceramic (UHTC) composites hold great potential for use as leading edges and nose tips in hypersonic and atmospheric re-entry vehicles. UHTC composites must be joined to themselv ...

ABSTRACT:This Small Business Innovation Research Phase I project will develop a vacuum compatible, high gradient insulator (HGI) based on low SEE yield aluminum nitride (AlN) ceramic with high surface ...

High order mode (HOM) absorbers are very important to stable operation of accelerators. It has been very difficult, especially for superconductor radio frequency (SRF) accelerators, to find a suitable ...

NASA missions for planetary exploration require high power, long-life Hall thrusters. However, thruster power and lifetime are limited by the erosion of plasma channel walls. Current plasma channel i ...

The development of an advanced green monopropellant propulsion system could have significant benefits to a wide range of NASA space missions, from deep space satellites to manned space vehicles. Howe ...
