[amsat-bb] Water as Primary Method of Spacecraft Propulsion

NASA has just awarded a launch and a construction grant to Cornell University for a CubeSat designed to orbit the moon. Launch is scheduled for 2019. The core spacecraft technology involves a water electrolysis propulsion thruster which Cornell has been working on since 2009.

Makes me recall an article I read many years ago ...
