迈尔沃尔德说，迈因策尔回应称大型望远镜并非为观测如此接近地面的点而设计。但他指出，智利的那架却是为此设计的。
Myhrvold said Mainzer responded that large telescopes were not designed to point that close to the ground. But the one in Chile is, he noted.
为了更好地了解，实际上到底有多少具有潜在危险的小行星，迈因策尔和她的同事们，最近使用了在2009年升空的WISE望远镜，进行了一次最新的调查。
To get a better sense of how many potentially dangerous asteroids might actually be out there, Mainzer and her colleagues did a new survey with the WISE telescope, launched in 2009.
“不过，非常重要的是必须注意到，小行星数量少并不意味着没有，”迈因·策尔警告说。
"However, it's very important to note that fewer does not mean none," Mainzer cautions.
迈尔·沃尔德说，迈因·策尔认为用地面望远镜无法探测地球轨道以内的小行星，因为它们离地平线太近了。
Myhrvold said that Mainzer argued that a ground-based telescope could not detect asteroids within Earth's orbit because they would be too close to the horizon.
