Can anyone pick out Elon in a still image of the SpaceX control room?

Was that the first time the NASA TV live feed tracked the first stage, rather than the second, post sep?

Just remember people, this is all about ISS supply, not about recovery.

Who am I kidding.

Body language of the three controllers in Hawthorne didn't look happy.

Agreed hands on heads...no celebration in the crowd if you will...

Yup, hands on heads at MCC...looks like no cigar on landing...

Ascent successful. Dragon enroute to Space Station. Rocket landed on droneship, but too hard for survival.

The more detached attitude is that its only a failure if you don't learn something...and its a lot easier to be detached as a spectator.

felt like i was watching a repeat of the control room video from last time lol

might be fun to see them side by side

My hope, based on a hunch, is that they may need a redundant, perhaps optical radar lock, as oceans tend to move up and down. A shutdown of +/- 10 feet is not the greatest engine-off condition.

They were using landing radar on the F9R Dev test vehicle at McGregor and presumably are doing so on the flight vehicles.

Or, for preference, coming back to a known stable landing zone...on land.

So twice now the precision is good enough to hit the barge (or where it was supposed to be) - dry land doesn't have the z-axis movement to worry about.

Who am I kidding.

I guess there would be more people cheering here if the Dragon had "punched" the ISS and the 1st stage had docked perfectly with the barge.

Anyway, makes me wonder if pilots taking remote control of the First Stage (from some 5 km horizontal distance to the barge) wouldn´t help at all.

I think you are on your own with that one.

I was writing something related to first stage landing technical hurdles that SpaceX has already retired, but clearly something is missing.

What technical hurdles are left to solve?

Intact landing on ASDS.

I think the problem could have been that the drone ship suddenly moved up in some way...
