The article states that North Korea had a successful test launch of a solid-fuel missile, which is harder to detect by foreign parties. It further explains that liquid-fuel rockets must load the fuel separately, and that the carriers that carry the liquid can be seen by satellites; the solid-fuel missiles, however, don't have this issue, and can be fired much more secretively, making them harder to prepare for overall. Japanese Prime Minister Shinzo Abe called the launch a challenge to the world, and will bring it up at the upcoming G-7 summit in Italy.
