It seems that one of Jupiter’s Moons, Ganymede, has more water than all of Earth’s oceans put together. If that is true, it means that a highly abundant alternative source of water is available for use. The acquisition of this water could be quite expensive, but it could be part of strong industry in water transport and processing. Hydrogen fuel research could expand and the water on Ganymede could be useful to that end. As well, plans for manned Mars exploration and development may have just become more realistic with this huge source of water nearby.
