Why Does E=MC2?

"If we could build a spaceship that could whisk us into space at speeds very close to light speed, then the distances to the stars would shrink, and the amount of shrinking would increase the closer to light speed we could travel. If we managed to travel at 9.99999999 percent of the light speed, then we could travel out out of the Milky Way and all the way to the neighboring Andromeda galaxy , almost 3-million light years away, in a mere fifty years." - Why Does E=MC2? by Brian Cox and Jeff Forshaw

Very cool but the people on board that ship would still have aged the equivalent of 3 millions years wouldn't they?
