NASA has unveiled a design plan for its latest rocket, the most powerful since the Saturn V that took U.S. astronauts to the moon in the 1960s, the New York Times reports. This rocket should be the backbone of future space exploration missions, including visiting asteroids and Mars, that will be increasingly important in coming decades. The rocket is expected to cost $10 billion over the next five years, and a crew capsule and launching pad would add another $8 billion. The rocket will be able to lift 70 metric tons to low-Earth orbit, and should see its first unmanned test flight as soon as 2017. Future versions will be even more powerful, although plans will, of course, depend on future budgets.
