Anyone got the timing?

Rewind right to +2:18, You can see the explosion start at the FRONT of the craft, and it looks like the Dragon pops off at +2:20.

Dragon in the debris cloud

Anyone know with certainty whether Dragon can parachute safely back, if it remained intact?

Dragon did pop off early in the explosion, Any chances of recovery?

Watching from my home on Merritt Island.
It appeared the Falcon pitched over a bit, broke up then a few seconds later a second break up event.
Was watching with naked eyes, so no details.

Interesting; TVC failure on one or more of the Merlin-1ds, perhaps?

Hypothetically, I suppose so. However, I don't know if the on-board computers are programmed for that contingency.

SpaceX replaying launch report now...

FWIW, I'm sure I also heard a call (twice) that the ASDS had lost data, maybe 30 seconds prior.

Just seen the replay on Sky News. Totally nominal, then it LOOKS LIKE a structural failure up at the region of the second stage, and I think I can see the Merlins still burning for several seconds inside the cloud...

Range confirms loss of vehicle. Lost at 2:19. Not exactly sure what happened.

What was the last call before breakup, Mvac prechill? Looks like the vehicle got engulfed in a LOX cloud from the front. S2 tank/Mvac failure?

BitBanger · « **Reply #192 on:** 06/28/2015 02:39 pm »

Wasn't MVac chilldown announced just prior to the event?

Youtube replay of launch with marker a few seconds before the start of RUD.

edit: sorry seems the marker doesnt work here. It's 23min 34s

Aircraft to be in the area in about six minutes. Debris impacted down range.

Mapperuo · « **Reply #195 on:** 06/28/2015 02:41 pm »

Dragon or atleast a Dragon shaped object is certainly visible JUST before the big failure at 2:34

Earliest frame I could grab of the anomaly.

Agree. I'd expect 1st stage rapid depress to cause quick collapse at that G level and M1d shutdown due to loss of head pressure. Kinda looks like the 2nd stage let go and then the Dragon got thrown away.

meekGee · « **Reply #198 on:** 06/28/2015 02:42 pm »

Two clear pictures:

1: Engines have turned off
2: Explosion in front
3: Engines actually still on

EDIT: Engines off is arguable probably.
EDIT2: I take back the engines-off. Explosion starts at front and works backwards, and is more like rapid expansion of propellant.

Since engines are on, does that mean no FTS? In that case, structural?

Falcon 9 experienced a problem shortly before first stage shutdown. Will provide more info as soon as we review the data.
