Criticism of human space flight comes from many quarters. Some critics point to the high【W1】______of manned missions. They contend that the National Aeronautics and Space Administration has a full slate of tasks to accomplish and that human space flight is draining【W2】______from more important missions. Other critics question the scientific value of sending people into space. Their argument is that human space flight is a(n)【W3】______"stunt" and that scientific goals can be more easily and satisfactorily accomplished by【W4】______spacecraft.
But the actual experience of astronauts and cosmonauts over the past 40 years has decisively shown the merits of people as【W5】______of space. Human capability is required in space to install and maintain complex scientific instruments and to conduct field exploration. These tasks take advantage of human【W6】______experience and judgment. They demand skills that are unlikely to be automated within the foreseeable future. A program of purely robotic exploration is【W7】______in addressing the important scientific issues that make the planets worthy of detailed study.
Many of the scientific instruments sent into space【W8】______careful emplacement(放置)and alignment(排列)to work properly. Astronauts have successfully deployed instruments in Earth orbit and on the surface of Earth’s moon. In the case of the【W9】______telescope, the repair of the originally flawed instrument and its continued maintenance has been ably accomplished by space shuttle【W10】______on servicing missions. From 1969 to 1972 the Apollo astronauts carefully set up and aligned a variety of experiments on the lunar surface, which provided scientists with a detailed【W11】______of the moon’s interior by measuring seismic(地震的)activity and heat flow. These experiments operated flawlessly for eight years until shut down in 1977 for fiscal rather than technical【W12】______.
Elaborate robotic techniques have been envisioned to allow the remote emplacement of instruments on planets or moons.【W13】______, surface rovers could conceivably install a network of seismic monitors. But these techniques have yet to be【W14】______in actual space operations. Very sensitive instruments cannot tolerate the rough handling of robotics deployment. Thus, the【W15】______versions of such networks would very likely have lower sensitivity and capability than their human-deployed counterparts do.
【W14】

答案
demonstrated
解析
此处是指,these techniques能否使用已经得到证明,应用动词的被动语态。故答案为demonstrated。
