The fruits of the previous moon expeditions have provided scientists with astounding information and insights. Over the years, this information has helped shape technological advancements in fields as diverse as biology, geology, astrophysics and chemistry.
In 2018 -- or so says this 2007 documentary -- astronauts will once again set foot on the lunar surface, with the goal being to ultimately establish a presence on Mars and beyond. Astronauts, scientists and engineers will use the moon as a training ground to develop and refine the technologies that such an ambitious vision demands.
