More surprising was the success of the launch, which makes North Korea the tenth member of the world’s “Space Club” (the ninth member was Iran, which successfully launched its Safir rocket in 2008). The Unha-3, a three-stage rocket weighing 92 tons, follows the Unha-2, which failed spectacularly in 2009, so the evident progress that North Korea has made in its missile technology in such a short period has shocked governments around the world.
更令人意想不到的是导弹发射成功，朝鲜第十个加盟全球“太空俱乐部”（2008年伊朗成功发射萨菲尔火箭后第九个加盟）。继Unha-2之后的Unha-3是重达92吨的三级火箭，2009年Unha-2在发射时曾遭遇惨败，因此朝鲜导弹技术在如此短期内的显著进步令各国政府深感震惊。
