On Thursday's Backchat we're talking about China's latest space mission.

The Shenzhou-16 spacecraft has successfully docked with Tiangong space station after sending China's first civilian into space.

And as they're orbiting around the earth around 400 kilometres above the surface, the crew will carry out all sorts of experiments – from quantum physics and further verifying Einstein's General Theory of Relativity, to even probing the origins of life.

What's the significance of this latest milestone in China's space programme? How fast is China's aerospace technology developing? And how long will it take before we can send a HongKonger into space?

After 9:45am, we'll look at efforts by the WWF and the Chinese University to revive Hong Kong's corals.
