Designs on Moon

Later this year NASA plans to launch its first new missions to the moon in more than 35 years. The goal: To scope out likely spots to land and create a habitat where astronauts can stay for longer than the Apollo program ever dreamed.

But therein lies the controversy: Mars, with its potential stores of oxygen and water, has the highest potential for long-term human habitation. The moon, even in NASA’s manned spaceflight plans, isn’t supposed to be the primary destination for humans’ return to space. Some scientists are asking why we are working so hard to return to a place where we’ve already set foot.
NASA’s plans suggest that the lunar habitat is, to some extent, meant to be a kind of stepping stone, a field laboratory where scientists can test out new technologies, investigate how to mine the surface and figure out how to keep humans alive in the harsh lunar environment. It’s a classroom and staging ground before taking the much bigger and more dangerous leap to Mars.
Meanwhile, the moon is no longer the finish line in a race between two superpowers; instead, other nations are joining in. In addition to the U.S. and Russia, China, Japan, India and other nations have announced plans or have already launched missions of their own to assess and stake a claim in the new era of the space race.
When we last set foot on the moon in 1972, no one imagined it would be more than three decades before we would return. Plans to return humans to the moon are under way - but will the moon be a stepping stone to Mars or a destination all its own?
