Por que devemos explorar a Lua?
Porque ela pode nos dar mais uma fonte de energia.
A potential gas source found on the moon's surface could hold the key to meeting future energy demands as the earth's fossil fuels dry up in the coming decades, scientists said Friday.
Mineral samples from the moon contained abundant quantities of helium 3, a variant of the gas used in lasers and refrigerators as well as to blow up balloons.
"When compared to the earth the moon has a tremendous amount of helium 3," said Lawrence Taylor, a director of the US Planetary Geosciences Institute, Department of Earth and Planetary Sciences.
"When helium 3 combines with deuterium (an isotope of hydrogen) the fusion reaction proceeds at a very high temperature and it can produce awesome amounts of energy," Taylor told AFP.
"Just 25 tonnes of helium, which can be transported on a space shuttle, is enough to provide electricity for the US for one full year," said Taylor, who is in the north Indian city of Udaipur for a global conference on moon exploration.
