One more tidbit just came through. Accuracy was about 4 miles from target.
4 miles from target for both halfs, or just recovered one, or just the one that wasnt recovered?

I think they are only fitting recovery hardware on one half right now.

Obviously (?) they can improve accuracy in the future. My question was: is it good enough now to start trying to avoid wetting the fairing? Unless they've already firmly decided not to pursue mid-air capture in any circumstances, it seems like they've cleared the blockers from the critical path for that option.

A hovercraft could cover 4 miles in a few minutes, it could also self inflate a "bouncy castle". Probably not good in rough seas though.

They could just use a speedboat with a winch on the back.
Hook on the the para-foil harness and bring it back like a para sailor.

This startling, state of the art digital rendering, along with the screen name "Does It Float" gets a like and a comment.

Any updates on the fairing yet? has it been spotted ? it seems like everyones really tight lipped at the moment about it

Go Searcher still hasn't shown up on AIS.  The SES-10 fairing is sitting under tarps next to the Spacehab building, here are some crappy driveby pics I got after the first NROL attempt:

Edit: Go Searcher is back in port.

some decent photos of the fairings for F9-FE (Full Expend)

http://forum.nasaspaceflight.com/index.php?topic=42846.msg1677217#msg1677217

the 3rd photo in the set shows a bit of the inside of the male-latch fairing, which i believe is the half that has been used in the recovery attempts

i think the missing section of black square might be the same as this piece seen in the new photo.

also, counting the squares at the base, we wouldnt be able to see the chute bags in this photo if they were there or not

Is there already an accepted abbreviation for this? If not, I don't see what's wrong with this. How else are new abbreviations established?

Why do we need an abbreviation for "expendable?"

mostly joking, sorry lol. But it would be interesting if there turns out to be expendable launch scenarios with/without fairing recovery.

Let SpaceX decide. We'll try to tease it out and once we do, use it. But making up our own seems a bad idea to me.

Elon posted a video of a fairing post-separation on Instagram:

It's from the SES-10 mission.

From my Instagram feed, Elon posted:

We did recover the fairing. It has onboard thrusters for positioning in space during reentry and a GPS guided parachute is deployed once it enters the atmosphere

I like the idea that they built a cheap but heavy fairing .... knowing that eventually they would reengineer it with more expensive but lighter materials... more expensive ONCE, yes,  but since now it's recoverable (the mass savings is used for whatever the recovery mechanism is), actually LESS expensive iff they mostly get it back.

they were thinking ahead.

People focus on SpaceX changing plans but they miss that they also have been taking the long view here for a long time.

Also I don't see the need for a lot of heat shielding (said upthread a lot).... These have very low density so terminal velocity is low.

Not sure why I was reading page 30 of this thread earlier this week... but this is contradicted by the video below. Elon explicitly says it's engineered to optimize for mass and claims it may even be the "lightest-weight fairing of its kind."

I think the key words here are "of its kind".

You do realize that this is a 7 yr old video, right? And this was YEARS before the first fairing actually flew, and by that point it had changed a lot. According to people knowledgeable on this forum, the actual flying fairing (not that early prototype) is not the lightest fairing of its kind. It may be the cheapest, but not the lightest.

Worse ... it's a NINE year old video.  It was uploaded (by whomever) in 2010, but was actuully shot in mid 2008.  He refers to Falcon 1 flights 3 and 4 in the future.
