FCC has approved SpaceX's application for radio transmissions for stage recovery operations. ASDS position for the landing attempt:

28 6 53 N
73 38 32 W

This is 11 nmi east (and a bit south) from its position for the JCSAT-14 landing, with a net increase of 10 nmi from the Cape.

https://apps.fcc.gov/oetcf/els/reports/STA_Print.cfm?mode=current&application_seq=71189&RequestTimeout=1000

Expecting Saturday evening departure based on latest launch date.

New image of OCISLY taken on May 16th, appear to show 25 circular holes that are new. People over on R/SpaceX think they are either hold down points or cameras
Were visible on deck during CRS-8 return coverage as well.

Yup. Definitely not new. And most decidely not part of a water deluge system.
My WAG is that they are radar reflectors to help the stage zero in on OSICLY.

Elsbeth III has just moved to OCISLY.
May be time for a new recovery thread.

I wonder how frequently SpaceX plans on repainting OCISLY's deck?  It now bears the blast and scour marks from two recoveries in a row, pretty much erasing the "X" and wiping out about a quarter of the yellow ring.  Heck, pretty soon, we won't have a good way to determine who won landing bingo, since there won't be much paint left on the deck to calibrate the landing spot accurately...

Elsbeth III just notified port they are setting out to sea with OCISLY.

5 days ahead of launch, right on schedule for GTO missions.

I have faith that the relentless, unceasing addicts at NSF will rise to the challenge

Hate to say it, but they have been there all along. I've even commented on them in the past.

Now that they have all the press footage they need, I'd imagine not too often. It's harder to weld on a primed & painted deck, so if you can handle a small amount of rust (most of which would be wiped back to bare metal by the exhaust anyways) I can't see why they'd bother.

..and there will always be ways to determine who won landing bingo.
With sufficient thrust, pigs fly just fine - however, this is not necessarily a good idea. It is hard to be sure where they are
going to land, and it could be dangerous sitting under them as they fly overhead.

Could someone split the posts about the ASDS model to their own thread? I think all the information that we need to make a scale S1 for the model ASDS.
Where can I apply for SpaceX fanboy?.

There's (already) a modeling thread on this forum, with info on both ASDS and S1 models.  I recommend the AXM paper model of S1-with-legs-deployed, myself.

The Go twins set out from Port Canaveral this morning about half an hour ago.

Not sure if barges handle tropical storms well?

Surface wind forecast at the LZ for Thursday evening: 23 knots with gusts to 31 knots.

Probably no worse than CRS-8 landing conditions were.

Good... part of the landing test series needs to be... push it hard into high landing crosswinds...
CRS-8 showed it can do it... once... (lean into that wind)...  :)
Can it do it twice?... ???
Can it do it in a 60+ knot gale?...  :-\
Gotta find those envelope edges folks...  8)

I think the worry is more about what could happen on the 4-5 days it will take to get back to shore. They have operated the barge in high seas before, during the Discovr landing attempt I think, so it is not totally foreign to them.

this is a great place to see tropical development http://tropic.ssec.wisc.edu/
http://nhc.noaa.gov

and for detailed wind and shear use this link http://www.spc.noaa.gov/
http://www.spc.noaa.gov/exper/sref/ for gif sequence of Wind and shear

I understand wind is a concern for landing -- what about rain or dropping through a thunderhead?

Could this be an ASDS Rainout?

I expect they'll land the stage whether or not the ASDS happens to be underneath it.  It's a free test.

And the only way they'd move the ASDS is if it couldn't take the sea state (or if conditions made the tow operation hazardous to crew).  They're clearly not afraid of aiming the stage at the ASDS.
