How long are those boats out for? How many crew on each? And what is the purpose of each?

somebody correct me if I'm wong but :
Turns out I was not completely right. See Jim's details below.

Elsbeth III is the one that tows OCISLY and carries the "securing the booster" activities after landing, along with Go Quest. Probably also some tracking/comms going on to some degree.
Go Searcher is alegedly the ship that works on the fairing activities. So far we did never see it coming back with fairing on board, though (even debris). So no real clues about its exact missions. I think we, however, have seen it perform some patterns that look like sonar reasearch of areas, that kind of stuff. It may very well be that all 3 ships just look after OCISLY, in reality. We don't know.
As for the crews ... no idea !

Did this article get posted here before?  It appears to have been written shortly after the CRS-8 landing.

Edit, for Kabloona: This is not to say this article has anything in it that we didn't already know at that time.  It was simply an article I hadn't seen before, from a different perspective than our usual here.

It only tows, it does nothing else.  Go Quest has the comms, the people, the equipment, etc for dealing with the booster.

Which appears to have been sourced (almost?) entirely from material researched and reported on this site. Just sayin...nothing we didn't already know. Plus some incorrect statements, ie the F9 and the ASDS do not "talk" to each other.

But, thanks to Capt Jeff for reading NSF.  ;-)

Elsbeth tows the ASDS from the front.  In the harbor they use a line at front and back for better control, as seen on various harbor cams. Although usually a random "on call" tug for the port will do this role, I believe that Go Quest can also do guide the aft if needed, for example when at sea far from port.  This is based on marine track showing "formation sailing"; I don't think we've ever directly seen this.  Perhaps Go Quest is sailing in formation for some other reason.

Go Quest has all the comm gear and manpower to service the ASDS and the landed stage.  You can see the SpaceX containers on its aft deck.

Go Searcher is a bit of a mystery. Its deck is relatively clear, so speculation is that it is helping in recovery tasks, and might in fact be the fairing "searcher".  But for all we know it might be out there simply providing additional crew accommodations or fire-fighting capability or backup or something.  Because of the absence of SpaceX containers aboard, it's not likely to have a direct role in telemetry or comms.

The final element in the fleet is aircraft. Elon's personal jet has gone out to the recovery area in the past to receive telemetry and image the landing.  A NASA plane was also used to do long-range thermal imaging of retropropulsion.  We keep closer tabs on the marine sites than the aviation sites, so it's possible that these (or other) aviation resources have been deployed more often than we think.

Sorry if I sounded too critical. Yes, nice to see others out there are interested.

Nice find!  To add to the incorrect statements list: "enhanced hull rigidity" - to the best of our collective knowledge, they did nothing of the sort.  Nor should they need to.  These barges are extremely sturdy and impressively tough and if they weren't I'm sure SpaceX would have chosen someone else to supply their fleet.

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.

This may have happened as part of their repairs after the SES-9 "hard landing" when they had to replace a section of the deck and presumably some damaged areas underneath.  Alternatively, it could be a misinterpretation of some of that work.

Hmm.. To me, "enhanced hull rigidity" means beefing up the hull in various places from stem to stern - not just the like-for-like deck structural repair we saw.  It would require a complete re-survey of the vessel and I can't see any evidence of this in the ABS records on-line.

I'm not saying it didn't happen, only that I, personally, have not seen any evidence of this in the pics available on-line and, if they did, would be interested to know why.  Agreed it's most likely a misinterpretation of the work done..

Departing Port Canaveral right now - the gizmo is on the deck of OCISLY - four jack stands on a much larger octagonal base right down on the deck - I got a lot of photos on my good camera, but not on the phone, so I'll post a link when I get back at the end of the week if no one else beats me to it. Wanted to send this while still in cell phone range

Ohhh the cruelty.. ;) :P


Even the worst picture on your phone will do... ;D

I posted the link to the photos under the "Roomba" thread in SpaceX General - thought that would be more appropriate than here...

The link to the new photos, for the lazy:

Having given the "other thread" a quick look, I agree it is the more suitable place for kremlinology about how this thing will work.

Same information from the SES-10 thread, but with direct link to MT listing:

OCISLY or at least Elsbeth III left Port Canaveral.

It's pretty awesome that the ASDS is underway and it's become so ho-hum that this thread is barely updating.
