The launch succeed when the Tianhe solar panel is fully extended. China is a powerhouse in solar energy, the solar panel used by CSS is very efficient. When it's completed, they'd generate close to power of the ISS.

There is a backup copy of Tianhe core module dubbed Tianhe-2. Since Tianhe is successfully launched, Tianhe-2 is expected to be launched as an extension to the basic CSS configuration at later date.
Aside from the core module and two space lab, there was originally a Hubble class telescope installed in Mengtian lab. Now the telescope is separated into a companion module Xuntian flying alongside CSS. Xuntian telescope can dock with the CSS for maintenance.
