The recent talks between President Donald Trump and Chairman Kim Jong-un in Hanoi failed when the U.S. overplayed its hand. In his New Year speech Kim had already warned that he was ready to take a "new way" if such a problem would occur. As we wrote:

History shows that North Korea has always gamed out such talks. It is always prepared to let them fail and it is ready to take the next step whenever that happens. The "new way" may well allude to some new weapon that North Korea is ready to test. Cruise missiles are a possible candidate.

There are no cruise missiles (yet) but a satellite launch that is supposed to pressure Trump to come back to the table:

Commercial satellite imagery from March 6 of North Korea's Sohae Satellite Launching Station (Tongchang-ri) indicates construction to rebuild the launch pad and engine test stand that began before the Hanoi Summit has continued at a rapid pace. Given that construction plus activity at other areas of the site, Sohae appears to have returned to normal operational status.
