SpaceX F9 : Starlink v0.9 : May 23, 2019 - DISCUSSION

I have got to say, the Falcon 9 is a beautiful bird.

The long lean proportions are great.

What is with the pulsing of the protective sheet over the Mvac?  I have never seen that before.

It's not doing it about about 2 min after however...

Dead freaking center

To me it looked like looped video.

Here in North Carolina, I finally saw an F9 fly. The second stage looked like a comet going by. Even saw the bright, very bright, reentry burn of the first stage......I have to say it........SQUEEEEEE!!!!!

Hope you take some pretty pictures.

I really hope they use starlink to relay video from the droneships. While the suspense of landing burn success is fun and all I just want to see it land without the cutouts.

Happens often since SpaceX started covering the MVac plumbing with Mylar. I seem to notice it on every launch. I think there’s a vent underneath that captures and slowly releases purge gas (GOX tapped off the propellant feedline perhaps?)

[MKremer]

I'm not sure even a phased array antenna would keep a signal lock with the violent shaking an engine firing 50m away causes.

Looks like we have a slow BBQ roll going on

That's awesome. I tried watching from southeast Virginia, but I didn't know precisely where to look and there was a bridge sort of in the way. Will have to try again...

Southeast and low, I would think

[Robotbeat]

Did you see it? If it was clear, the stack should've been visible...

No this was different.  It was a perfectly timed pulsing of the Mylar cover.  What's even strange is that you could see the same pulsing on the bottom of the sat stack in the video....I've watched a lot of launches from SpaceX...never seen the perfect pulsing before....strange....

At what time?

[CJ]

That was one heck of a light show with the grid fins right after the entry burn, up until loss of video.

I wonder of this was their most difficult landing yet, at least for block 5 (due to the high mass of the payload)? I can;t recall seeing the ASDS this far out before. To be honest, I would not have been surprised had this landing failed. I'm also wondering if this was a 3-engine landing.

I am hoping that the sat deployment goes well, and that there is video.

It starts are t+ 2:58-3:29.  You can see the same "pulse" on the bottom center of the sat stack at t+3:30

From where I was, it surprised me how high up it was. Second stage was around 40-45 degrees above the horizon and reentry burn seemed about 25 degrees.

[Roy_H]

Does anyone know why the graphic showing the second stage shows 2 orbital paths?

Those thruster pulses are cold.
