The reasons for the two crises in The Wandering Earth 2

The two crises in "The Wandering Earth 2" are the space elevator crisis in 2044 and the moon crisis in 2058.

During the space elevator crisis, due to unknown reasons, the mission of a large number of drones in the Gabon base was changed from protecting the space elevator to destroying the space elevator, which eventually led to the crash of the "Ark" space station. The crash of the space station caused a disaster in the Gabon region. Countless lives were lost.

During the lunar crisis, due to unknown interference, the three planetary engines at the lunar base were continuously overloaded, causing the moon to deviate from its orbit and crash into the earth. If the moon passes a certain critical point, widespread species extinction and irreversible geological disasters will occur on the earth.
