Today's press conference announcing the confirmation of water on the Moon highlighted the fact that water is not only present at the lunar poles, where it has been suspected to exist in perpetually shadowed craters, but also (in lesser quantities) in the soil all over the Moon. This confirmation of lunar water is being called a "game changer" in terms of enabling human activities, including providing fuel for spacecraft.
In a separate media event today, more confirmation of the presence of water on Mars was discussed. It turns out that the Viking 2 lander, which arrived on Mars in 1976, may have been inches away from discovering ice under the Martian soil.
