NASA has made it clear they want astronauts back on the Moon in 2024, and now, they are zeroing in on the Red Planet -- the US space agency confirmed that it wants humans to reach Mars by 2033. Jim Bridenstine, NASA's administrator, said Tuesday that in order to achieve that goal, other parts of the program -- including a lunar landing -- need to move forward more quickly. "We want to achieve a Mars landing in 2033," Bridenstine told lawmakers at a congressional hearing on Capitol Hill.
