Space X Launch & Landing Control

Is that new?

It's their control facility, they just added "landing" post-ORBCOMM

That fact on the webcast about the new flame trenches allowing testing of reused stages at the cape was kind of nice to hear about!

What's this?

This will be the first RTLS with clear skies.

I am expecting incredible landing footage.

The simulation is still showing stage 2 to be at SLC-40.

Let me guess: The tracking transceiver is still in its shipping box in the HIF?

Arrggghh, was hoping the ground tracking shot would be kept on for the whole 1st stage trip! Never mind, another good mission (so far!).

Same here. This would've been an incredible sequence. Also, one that flat earthers would have a real hard time debunking; ]

This one was pretty fantastic but I still think NROL-76 had better, near-continuous footage of the first stage all the way from launch to landing.

This is the first technical webcast SpaceX has done in a while, isn't it?

The NASA TV coverage had a pretty good tracking cam on the way down, like NROL-76.

I hate to have a repeat of the "calipers" but there was most definitely a washer flying around at the end of the NASA TV replays during Dragon separation! No way it was ice this time IMO.

Yes I think it is the first technical webcast in a while.... I was surprised to see it...

Also I thought it was charming that one of the presenters shared that CRS-6 was her first mission as an employee. The company is growing big time, that wasn't that long ago...

Nah, they just forgot to grab the second stage on the way to the pad--you know how it goes when it's the morning of a big event, you forget the little things. That's why they had to fly the first stage back to go pick it up. And you just know traffic at 51.2deg inclination'll be a nightmare by the time they're back in the air...

Congrats to the SpaceX team on the smooth launch and landing. After 45 days of waiting and a No-Launch November (surprisingly, SpaceX has never done a launch to orbit in November), it's nice to see the Falcon spread her wings again!

... because ice never forms in toroids?

Rewind and actually watch it.

Love that NASA burnback and landing footage.

A big round of congratulations to all of those pad-rats, welding techs, cable runners, concrete workers, etc, etc, involved in bringing SLC-40 back to operational status after AMOS-6. I know it was a long and arduous process. I hope a well deserved Christmas holiday begins today.

Two issues from the coverage:

1) On the launch replays from NASATV, the LC40 camera on the tip of the lightning mast showed what appeared to be a large red rag come off of the vehicle (I think from somewhere around Dragon) and flutter past in the clouds of exhaust. FOD?

2) Periodically during the technical SpaceX broadcast they went to an aerial image of LC40 from the southeast. It appeared to be a still image, but would have been an incredible angle on the launch. What was this image? (and comment - if they can have a drone in the air to film the landing, why not also use it to film the launch? They did this to great effect with the hops at McGregor, when will we get to see that perspective for an orbital launch?)

It's a video fed from an animation--normally that animation shows a track of the second stage and first stage telemetry overlaid on a globe, which zooms in and rotates to show it. For some reason this flight, the second stage tracker never updated to leave LC-41 (data glitch or something feeding the animation), thus it showed a static image of the pad area and hence my joke a page or so back.

Maybe it's just me, but one of the coolest things about this video of Stage 1 entry and landing is that S1's downward-looking camera shows its own contrail from ascent, clearly, from about 28:45 to 29:45. As the Landing Burn starts, the contrail is obscured...but it's almost as if it passes near or through the contrail.
