• According to Janhunen et al. (2015) the E-sail could make asteroid mining feasible by providing essentially free logistics in the solar system outside of Earth’s magnetosphere. After finding a suitable water bearing asteroid, a mining unit is could be sent by the E-sail to extract the water from asteroid soil.
  • This can be done by heating the material and letting the evolving water vapour condense in a cool container. When full, it is separated from the mining unit and transported with an E-sail in to the orbit of Mars or Earth where it is split into hydrogen and oxygen and liquefied. The liquid hydrogen/oxygen (LH2/LOX) fuel can be used to fill the tanks of manned vehicles travelling between Earth and Mars.
  • The Electric solar wind sail facilitated Manned Mars Initiative, EMMI, could provide a fundamentally new, economically sustainable way to approach manned Mars flights.
