Can you believe that at exactly 13:16 GMT (T-0) SpaceX tweeted "Are you excited about the future of spaceflight". Hilariously bad timing
Congrats China!ISS will always be my favourite space station, but Tiangong is cool too
Shortly after TG-1 seperation, video seemed to indicate the vehicle ignited its own engines. Is that indeed what happened?
In this image the launch time looks like 1316:03.507UTC... Any help?

To make sure there is no thrust imbalance? But then S1 does have 4 engines, too, 4 engines should rather help to level these.Separation of the boosters takes place at T+155s and first stage separation takes place at T+159sOK, but why? I mean: it's an additional separation event and I don't think these 4 seconds will make a significant difference in payload/delta-v so there has to be some reason why they add a complex separation mechanism.

Mir, ISS, Tiangong: incidentally, how difficult would it be to have three stations at the same inclination ? Would that cause any issues ?
More precise orbital parameters:Perigee: 200.046Apogee: 346.854Inclination: 42.757Orbital period: 89,7 minutes
Photo suggests there is at least one backup for TG-1... or are these the three labs planned, already integrated?
