The U.S. should aim for the moon, not asteroids or Mars, say space veterans Robert Walker, former chairman of what is now the House Science, Space and Technology Committee, and Scott Pace, director of George Washington University’s Space Policy Institute. The U.S. should talk to other nations about partnering in space, they say. And, Pace said, "[w]hen you do that, you don't hear we want to go to Mars next week. You will not hear asteroids. You will see a willingness to work with the United States. But the one thing they could do, which is return to the moon with the United States, has really been left on the cutting room floor."
