Well, they've got about a 15-day mission in prospect. And I just clean get away. It's about a nine-minute ride to their initial orbit. After about two minutes, the other strap-on boosters that you see at the bottom of the rocket, they'll come away and then the main course stage then will separate and then they'll go with their upper stage. They'll lift them to a height of a couple of hundred kilometers above the earth, but over the course of the next 40 hours or so, they will have to raise that orbit up to about 335 kilometers and that'll bring them then towards Chianggong-1. This is the space lab that they launched a couple of years ago. It's a single module and it's a test. It's a demonstrator of the space station that they hope to build at the end of this decade. They're much bigger construction. This will have three or four modules all interlocked. It'll be serviced by robotic vehicles just as we see with the International Space Station. But it'll... It's a learning curve for the Chinese here. They have to understand how you do this. Things that the Russians, the Soviets had learned, the Americans have learned Europeans, the Japanese, Canadians. They have learned how to do this over the past 40 years. And the Chinese are in a process of catch-up here and they're having to run fast to catch up.
