Get Up To Speed on Tiangong-2 Before Launch

Great rundown of Tiangong-2 by Rui C. Barbosa for NASASpaceFlight:

The original plan was for Tiangong-2 to be launched at the end of 2013 or early in 2014. However, following the successful flights to Tiangong-1, China changed the original roadmap.

That path involved the new orbital module being used to test technologies that will be essential to the future Tiangong modular space station, the first module of which – the Tianhe Space Station Core Module – will be launched in 2018.

Having an increased payload capacity, the new Tiangong-2 space station will use its improved living conditions to verify key technologies, such as on-orbit propellant resupply using the new Tianzhou logistics vehicle.

Tiangong-2 is set to launch today. It’s an important mission for the Chinese space program, so keep your eye on it.
