A sweeping review of NASA’s human spaceflight program has concluded that the agency has an unsustainable and unsafe strategy that will prevent the United States from achieving a human landing on Mars in the foreseeable future.
The 286-page National Research Council (NRC) report, says that to continue on the present course under budgets that don’t keep pace with inflation " is to invite failure, disillusionment, and the loss of the longstanding international perception that human spaceflight is something the United States does best.
A major argument against returning to the moon was that it didn’t pencil out — that there wasn’t nearly enough money dedicated to the program. If the goal is a human landing on Mars, the current strategy won’t work.
" Absent a very fundamental change in the nation’s way of doing business, it is not realistic to believe that we can achieve the consensus goal of reaching Mars," Mitch Daniels, the former Indiana governor and co-chair of the committee, said Wednesday morning in an interview.
A 2009 committee appointed by Obama urged NASA to keep its options open while investing in spaceflight technology and letting the commercial sector handle routine trips to low Earth orbit. But the NRC reviewers argue that NASA and its international partners should focus on the "horizon goal" of Mars and do whatever it takes to get there, step by step, avoiding changes in strategic direction.
NASA officials, aware that critics see the agency as adrift, say they have already been moving in the direction advocated by the NRC. Their strategy targets Mars, just as the NRC report now demands, they say. " All this work will eventually enable astronaut missions to Mars," NASA Administrator Charles Bolden said in a recent NASA white paper.
"NASA’s been doing some work, and has been doing some thinking over the last six months, that is in alignment with what the NRC says the top-level goals are," said Greg Williams, a NASA deputy associate administrator.
But Williams was cool to the suggestion of a return to the moon, saying the airless moon offers little help in developing the kind of descent and landing techniques needed on Mars, which has a thin, troublesome atmosphere.
The NRC committee probed the philosophical question of why we send people into space to begin with. The committee concluded that the purely practical, economic benefits of human spaceflight do not justify the costs but that the aspirational nature of the endeavor may make it worth the effort.
According to Mitch Daniels, reaching Mars______.
选项
A、lacks funding from the business world
B、is a project that has made great achievements
C、is a generally accepted objective
D、will change the country in various ways
答案
C
解析
本题是细节题,要求考生理解第四段中Mitch Daniels说的关于到达火星的这一段,这段的大意为:国家(目前)在做事的方式上缺少根本性的改变,(而一味地)认为我们可以完成到达火星这一大家共识的目标是不现实的。关键点:...the consensus goal of reaching Mars.
