Look at those thrusters fire, I can see why hovering below station requires so much propellant. It almost looks like the Draco testing footage at McGregor.

andre working outline

I'm listening to Andre and looking at the camera/tracking output as shown on NASA TV, and the two don't seem to match up to me. It seems like he means "radius" when he says "diameter"... $:-\$

Dragon was "puffing" away quite merrily there once the Earth got dark behind it!

The ACS/RCS is quite an active little system, doing small thrusts every second or so.

-MG.

MEgan calling up that VVO thinks the cameras all look good, hopefully will get movement soon.

Are they still evaluating sensor data ?

He may have been looking at a different camera. I don't know which camera number we're seeing. I've heard #7, #9 and #10 called down. There's a "3" in the extreme upper-left corner of the display that might be the camera number, but that's a WAG.

I don't see that. Are you mistaking the strobe for thruster firings?

If something changes, it'll be posted. So yes.

Is it me or there are a LOT of stars visible on the background?

teams analyzing thermal imagers and cross checking with lidar, retreat command was a success

That wouldn't be a good sign as the camera is looking down at Earth. You're seeing hot pixels most likely.

Not stars but rather dead pixels in the CCDs of the cameras casued by long-term radiation exposure.

per PAO, making sure thermal spotters agree with lidar

Chris Bergin · « **Reply #196 on:** 05/25/2012 10:57 am »

Plenty of time for this evaluation too.

I thought dead pixels would show as dark. At best these would be hot pixels. Even if they showed up as saturated pixels, they should be very bright then.

should start again soon
