NASA In-Space Chemical Propulsion TIM

Future missions beyond Low Earth Orbit will require the development of highly reliable propulsion systems to ensure mission success. Various in-space propulsion systems are being considered in support of the Space Launch System Exploration Upper Stage, Human Landing System, Lunar Gateway, Mars Sample Return, Mars architecture studies, as well as other deep space missions and high risk/high reward technology demonstration missions. The purpose of this meeting is to bring the in-space transportation community together to discuss mission propulsion requirements, efforts to increase in-space propulsion technology readiness levels, plans for current and future missions, and emerging technologies for satellites and low cost small launch technologies. This forum will be conducive to sharing ideas and needs for future in-space propulsion development.

NASA Marshall Space Flight Center is conducting an In-Space Chemical Propulsion Technical Interchange Meeting on Wednesday and Thursday, 28 - 29 September 2022, at the Jackson Center in Huntsville, Alabama. NASA has committed significant effort towards understanding future in-space propulsion needs and development of in-space chemical propulsion roadmaps along with starting technology development. This TIM is intended to share the results of these efforts, to encourage organizations with similar interests to share their work/ideas, and provide insight into future development plans.
