A short video of the launch. They deploy the module into a very low orbit and it then self raises into its final orbit. It has side boosters at launch. Unlike US rockets the side boosters have liquid propellant engines. The US uses solid boosters. Liquid boosters are superior to solid, they produce much less vibrations.
For those with lots of time a long version with a lot of explanations, popular science style. I did not watch it, I admit.
