The relationship between space exploration and politics is a complicated one. The President is the only person who can pick a major goal like going to the Moon, but proposals that big have to go through congress for funding. To make sticking to big goals more complicated, each incoming president has the power to change major decisions made by his predecessor in space. With a president having two terms in office, it’s more likely his vision for space will be realized but it’s far from a sure bet. It’s possible that Obama’s second term will get us closer to seeing NASA’s mammoth SLS rocket flying the Orion spacecraft to the Moon, but history tells us that the constant rotation in the White House has a way of stopping big ideas before they get started.
