Wow, that Earth really has shrunk in the last couple of minutes.

Sorry Chris (know this is an update thread)

Is this view from Chang'E, or from the 3rd stage? The camera seems to rotate to wherever they want it to? Isn't it body mounted?

This is from 3rd stage

The probe will do some trajectories correction, but I don't think it will use the main engine. I think that this will only be used for the landing.

Probably also LOI right?



I'm not sure. The engine can be used for LOI or they can use the 150N thrusters for a longer burn. I'm not sure if the Trajectory Correction Maneuvers are made with the main engine.

It's cool. This isn't like a SpaceX thread where we've got the barriers up for crowd control! ;)

Great view of Earth!

Probably venting residual propellants has made it tumble.

2000 seconds after launch - and here's what you would get to see out of the window.

These english commentator statements are quote worthy .. "When can we say, that the first stage of the launch is a success ??" "So, does this mean that we are in space ??"

EDIT: on a second thought, for an uninformed observer, questions like these are perfect to get some understanding ..

Very impressive footage!
Even better then on SpaceX's last launch. Almost no loss of signal. Only just now, after it is out of range of the 3rd boat. ESA to take over soon?

It wasn't tumbling, that looked like a pre-programmed maneuver. Could be a collision avoidance maneuver and/or preparation for tank blowdown.

AOS should be in about 27 minutes

The commentary is more speculation then I would expect. Even the expert assumes a lot, or is it language barrier?

Thank you!   I assume that there was no plane change from the parking orbit.

They are very good, although they caught me out twice via my posting of their noted milestones....leading to 15 people posting "no Chris, it's not that" ;D

That was a lot of fun!

Lots of screenshots getting out there on twitter too (no problem if they are taken from this thread. We don't own CCTV ;)) Good to see lots of interest in this mission.

We'll be continuing coverage on this thread and then into landing coverage.
