FISO: Reducing costs of space exploration with advanced in-space propulsion

The latest presentation to the Future In-Space Operations (FISO) study group is now posted in the FISO Working Group Presentations Archive. Both slides (pdf) and audio (mp3) are available for the talk, Reducing the Cost of Exploration using Near-Term Advanced In-Space Propulsion – Roger Myers, Aerojet – March 13, 2013.

A key part of the proposal is to use slow but highly efficient solar electric propulsion (SEP) systems for cargo and faster but a lot less efficient high thrust chemical (e.g. LOX/LH2) propulsion for crews.
