航天：奧巴馬在肯尼迪航天中心發(fā)表演講

Space. What parts of it are we going to explore? How much money are we going to spend to get there? President Obama has a new strategy that answers those questions. He talked about it in a speech at the Kennedy Space Center yesterday. The president says he is 100 percent committed to NASA and its mission. He’s proposing that the agency get an additional $6 billion over the next 5 years, with a goal of sending humans to Mars by the 2030s. But under this plan, what you won’t see is this: people walking on the moon. President Obama’s strategy would cancel plans to send astronauts back there. He says, “We’ve been there before. There’s a lot more of space to explore.” Buzz Aldrin, one of the first men to walk on the moon, agrees with the president. But Aldrin’s NASA crewmate, Neil Armstrong, the first man to walk on the moon, disagrees. He’s part of a group of astronauts that have criticized the president’s plan. Other NASA officials argue that the proposal could cost thousands of people their jobs. The president believes it’s a way to move forward.
