China to launch grab-and-go mission to the moon this month

The Changa 5 mission, initially delayed in 2017, is set to launch on November 24th. It involves an unmanned mission package launched by a Long March 5 rocket. The package includes four vehicles: an orbiter, a lander, an ascender, and a reentry capsule. The orbiter will guide the mission to the moon, where the lander and ascender will collect rock samples. The ascender will return the samples to the orbiter, which will then bring them back to Earth for reentry.
