In the future, so many cores coming back and forth will mean master threads will be best. But for this one, the historic "booster that could", we should give it a standalone thread.

Second launch and landing:
https://www.nasaspaceflight.com/2017/03/eva-astronauts-prepare-iss-crew-vehicles/

Its first landing:
https://www.nasaspaceflight.com/2016/04/spacex-dragon-rtf-falcon9-launch/

The previous time it sailed into Port Canaveral:
https://www.nasaspaceflight.com/2016/04/falcon-9-first-stage-port-canaveral-asds-big-plans/

--

This thread will be for updates on positions and estimated time of arrival to help spotters. Remember to link, link, link any info (like marine traffic info) and photos etc. And of course, I'm sure that Port Canaveral webcam guy still has a fit over screenshots, so don't.

Ideal scenario is members of the main SpaceX communities - here, Facebook and Reddit (I know there's massive crossover) - deploy as many folk as possible and between us all we'll get some good coverage.

ASDS appears to be on her way.

Last 4 SAT AIS Positions have headings back toward the cape.

And this is a good reminder that just because one of your fellow space enthusiasts occasionally voices doubts about the SpaceX schedule announcements or is cautious about believing SpaceX has licked a problem before actually seeing proof that's true, it doesn't mean they hate SpaceX.

It's been almost 7 hrs since marinetraffic shows a Sat-AIS update
(did see the one Terr-AIS reported earlier and 2 Sat-AIS after that).
Was waiting until a more recent update, but here is the latest I have.
Hopefully Sat-AIS will update for this evening's projections.

Finally got another Sat-AIS with the fastest speed yet.  The other 9 last reported speeds are all over 8 hours old.

two more recent Sat-AIS data points came in and she's moving even faster.

So what is the average and max speed from marinetraffic?
I just have the free version of marinetraffic and can't see the numbers.
With ELV best efficiency was the paradigm. The new paradigm is reusable, good enough, and commonality of design.
Same engines. Design once. Same vehicle. Design once. Reusable. Build once.

One more data point since the last report here, a bit slower than previously.
Last Terr-AIS speed was 4.4, and Sat-AIS shows she's moving faster than this.
The user agreement with marinetraffic doesn't allow me to repost Sat-AIS specific details.

Pictures of the recovered fairing being returned to port now on the ASDS support ship activities thread:

Fairing is under a large tarpaulin but there are some glimpes around the edges.

The first of those photos shows what looks like some obvious tearing around the edges of what would be be fairing half separation plane. Not sure if that's repairable type damage in the context of reuse someday or not. Still an impressive feat to recover something so large essential intact.

remember, bouncy castles... no fairings should touch salt water... etc. This is a pathfinder, not the real deal. AFRS[1] comes next...

If this is tearing it could either be due to impact, wave action, or water intrusion into the honeycomb, or even damage trying to lift a large awkward item onto the aft deck... Bouncy castle obviates all that (but needs an AFRS[1]  unless they've REALLY increased precision of parafoil steering)

1 - Automated Fairing Recovery Ship, you heard it from me first :) but it's a logical acronym choice.

I don't see a crane on the recovery vessel so likely this was dragged onto the deck. Could be some damage from that also. Did I hear that the chute didn't open fully or something? That would mean the fairing also impacted the sea a lot harder than they liked. Still this is progress!

Where did you hear that the chute didn't open fully? Interesting rumor. I though parafoils were all or nothing, if they don't deploy correctly you have no control authority at all, or very little....

Edit: Here it is: http://forum.nasaspaceflight.com/index.php?topic=37727.msg1662235#msg1662235

This might need moving, not sure where, but this is fairing and the thread is for OCISLY for this mission. I guess? I'll ask Chris. Probably makes sense to have fairing for THIS mission and stage for THIS mission in one thread. PM or report to mod to discuss.

Another Sat-AIS datapoint.  Moving along at a better rate.
These projections should be read as "vicinity of the port"... what
happens when they get close is up to them & the port
(cruise ships, HMS nuke subs, waiting for Elon etc). 

When Terr-AIS data becomes available (~20nm from a land receiver?),
then I'll leave it to others cover the last bits.

My apologies, was reporting UTC instead of EDT for times.
Luckily, leetdan made me aware of this mistake.
Note projected times in previous message are corrected.
