The NSF Fleetcam was not

The NSF Fleetcam was not showing west coast until pretty recently, so it missed the beginning of the ballast tank filling which caused Might Servant 1 to get low enough in the water so that now the main deck is entirely awash.  I think it has a way farther down to go before the barge is in enough water to float.  Sometime soon, I think they'll hook up a tug and just move the barge away.  At least one tug is already on scene.

I personally missed most of

I personally missed most of the primary evolution as the landing barge floated off the heavy lift ship and was towed to dock.  So I was happy to get a second chance, which takes a lot less time than live viewing.

NSF has posted to Youtube a highlights video which in thirteen minutes shows material including:

1. The barge on the lift ship on arrival at Long Beach
2. Pretty and very detailed overhead video of the barge on the lift ship before unloading
3. The lift ship going down in the water as ballast is added
4. Tugs urging the barge to move off the lift ship
5. Tugs moving the barge on to land

There are ads at the beginning, and some in the middle.  

Disclosure: this has nothing to do with Einstein, and not much to do with space flight.  I just found it intriguing, and thought you could decide for yourself whether to spend any time with it.

Astra, abort after liftoff.

Getting up is not easy.

That was one strange-looking liftoff.  It power-slid sideways for a remarkably long time.

It is a 5 engine bird, which must normally take off with T/W right near 1.25.  So when one engine stopped producing power 1 second after liftoff, T/W was almost exactly 1.0 until enough fuel burned off to get things going.  Eventually it got up to about 40 kilometers, but "a day late and a dollar short" so they called a terminate.

Strange looking is an understatement.  Range safety should have called for terminate at that point.  Then again being a test flight maybe the safety parameters had not been exceeded yet so someone wanted data.

Looked at their previous launch and no slide, just up, so I think failure was at T-0.

I did notice just before engine shutdown the vehicle was not stable and was pitching back and forth.  Also it tumbled almost immediately after shutdown and pieces of the rocket were pealing off just before they cut the feed.

Quite nasty.

Sideways rocket ? I can do that all day long* in Kerbal Space Program. :-)

{ "approaching nominal trajectory" is my best case }

Cheers, Mike.

* recurrently that is. BTW does anyone else play KSP ?

SpaceX is targeting a five-hour launch window on Wednesday, September 15, opening at 8:02 p.m. EDT 

 for launch of the Inspiration4 mission – the world’s first all-civilian human spaceflight to orbit – aboard SpaceX’s Falcon 9 rocket and Dragon spacecraft from historic Launch Complex 39A at NASA’s Kennedy Space Center in Florida.

The young girl going on that flight nicknamed 'Nova' is SUPER SUPER smart!!! She's a cancer survivor and a Physicians Asst right now.
