When they attempt a fairing recovery on this mission, which thread would that be covered in, this one or some other thread?

BTW, just consider if this kind of electronic venue would have been available during the hey day of the Apollo program, can you imagine the conversations then???

My presumption is we'll treat this just like landed stages and their missions... The ASDS thread for particulars of the ASDS involved, the return, etc but some coverage here too such as the unload. Just substitute the Fairing Recovery thread for ASDS...

I hope you guys are prepared for them to do the exact same thing on another mission.

SpaceX expending end-of-life or obsolete boosters on their final mission has been speculated about extensively here. Usually in the context of customers getting expendable performance for flight-proven prices - but if a customer needs a launch ASAP and an EOL or obsolete booster is the first thing available, I wouldn't be surprised at all to see it happen again.

Edit - spelling is hard.

-Mainly directed at those who seem upset that SpaceX is "wasting" a booster
-Not all comments are based on speculation  ;)

What kind of wastrels would dump a perfectly good booster in the ocean after just one use?

Offline Flying Beaver

interesting, this may mean nothing, but on the patch s1 has no legs but has fins....

A press kit for this mission is finally available!

And is performing some kind of (four/nine engine?) boostback burn.  :o

On the mission patch, the lucky clover is out in the ocean. I wonder if SpaceX is hoping for some luck with a recovery experiment?

Is it just me or are those gridfins?

Maybe the patch is accurate and they're trying some entry lifting testing or something along those lines?

That's not very sooty!

We're probably not seeing the RP-1 tank in that photo

EDIT: I was right, but the RP-1 tank is seen in another photo. There is no soot, except for possibly the interstage. Also a visual confirmation of no legs

More to the point - is that a Block 5 interstage or is it just the lighting?

Nope, possibly soot or lighting. Block 5's interstage will be pure black.

Yeah, looks like grid fins.

I'm guessing they're doing a Cassiope-style water landing with grid fins just to get more data and precision.

Why did they clean the stage? Didn't Matt Desch say it wasn't cleaned? Did SpaceX see a lot more drag than they anticipated with CRS-13?

1036 had the entire resource base of Hawthorne, so may have actually been refurbished before 1035, or at the very least had excess intern labour.

I think Elon should charge $100 per square foot for the privilege of washing a F9; at the rate they're recovering them, BFR will be funded in no time flat.
Launches attended: Worldview-4 (Atlas V 401), Iridium NEXT Flight 1 (Falcon 9 FT)

There really isn't a need to post everything in both the Update and Discussion threads.

Would anybody try to land a F9 without legs on a ship structure? (I for sure wouldn't)
How sturdy are those two ships out there?
