I'd gladly trade for those Space mice and give NASA the ones we've had in our basement. We've never found ours to be picky eaters.

Ohhhh.... And here I thought they were checking the food for mice and found the mold, not that they were checking the food for the mice...
Webcast on this page.
Statistics for this launch, if successful.
65th Falcon 9 launch.
33rd landing
20th launch of the year
9th new booster of the year (12 reused flown)
2 more launches pending for the year.

90% go weather probability for 5th. I'll be at LC-39 gantry tomorrow. Mice food, or no mice food.
Looking good: SpaceX on twitter:
"Falcon 9 and Dragon went vertical early this morning ahead of today’s resupply mission to the Space Station. Dragon is loaded with more than 5,600 pounds of cargo; all systems and weather are for go for launch at 1:16 p.m. EST, 18:16 UTC."

The booster was lost. Some failure just before the landing burn.
1st landing failure on a F9 booster in over two years.
It looked like some sort of aerodynamic failure. Once the booster went wrong the systems couldn't compensate for the instability.

Looks like an uncontrolled rotation began just before they cut the video feed. Glad they were able drop it in the ocean.

You could see what the failure was on the telecast before they cut away. One of the grid fins got stuck at a fully tilted angle and the booster literally began to spin in a circle (the land below was rotating).
Honest to god, as I was watching the booster come down, I was idly thinking that the SpaceX engineers have done a really good job at programming the controls of the booster for a landing. However, I was wondering if their programming was flexible enough to work when a component failure, like a grid fin, occurred. Since the booster has grid fins, cold gas thrusters, and a gimbled rocket engine, in theory you could overcome one component failure by overloading the other components. A human pilot in such a scenario would have been trained in simulators for such emergency situations and how to land the rocket under failure scenarios.
I guess I got my answer :-(

Gives new meaning to using ‘flight proven’ booster. Perhaps they will be preferred to new ones

I scrolled back in the webcast before it ended and did these screen captures, from just before the stage started spinning out of control to a second before the webcast stopped the camera feed from the stage. The first image is during the re-entry burn and at that point everything appeared to be nominal at T+ 06:56.
After re-entry burn shutdown, stage appears to be stable, cold gas thrusters operating, at T+ 07:13.
Stage appears to be losing control at this point, rotating in a way I’ve never seen at this point in the landing process, T+ 07:24.
At T+ 07:31 the stage is spinning wildly. I found it rather terrifying to watch. In fact it seemed unreal, I had to remind myself this was a live feed and was really happening. It appeared that it could hit land, and not in a good way. The webcast commentators were silent.
A few seconds later at T +07:34, the stage is now maybe 10 seconds from touchdown, a second after this point the camera view from the stage was ended. Then I heard some cheers and applause from the audio feed of the employees at Hawthorne outside the control room and I thought maybe somehow the stage made a successfull landing, thought that seemed improbable. Finally the webcast commentator said the stage “made a water landing” and I breathed a big sigh of relief. Best possible outcome at that point.
