Isn't that Elsbeth III moored outboard of the GO twins in Jim's post #751?

Yup, that's her.

Public reports elsewhere that launch has slipped until the 5th, which makes OCISLY departure probable early Sunday morning.

Just wanted to say thanks to CameronD for having the patience to inject some realism into this discussion. As someone who works at sea I find some of the more outlandish questions and suggestions hilarious and/or exasperating.

SpaceX have got this right- off the shelf dynamic positioning system, barge, tug. Repeat as necessary for multiple recoveries.
Waiting for joy and raptor

Dumb question ya'll


Can someone say just how far the tugs are stationed away from the drone ship during a landing attempt?

Many thanks in advance.

Not a dumb question at all. The answer is: a few miles. Someone here is bound to have an exact number of miles for you.

Are the Go * ships which I know have bow thrusters able to self park or do they need tugs?

From the CRS-8 update thread;
Wow - SpaceX just tweeted a 360 degree video of the stage landing on OCISLY. You have to view it on YouTube, but if viewed with smartphone you can move your phone around to adjust viewing angle...





wasn't there water being sprayed on deck during the landing on previous attempts? I don't see them doing this in the newest video.

...water is life and it is out there, where we intend to go. I believe that this nation should commit itself to achieving the goal, before this decade is out, of landing a man or machine on a body such as the Moon and harvest a cup of water for a human to drink or process into fuel for their craft.

Thanks for the explanation of how the 3D view works.  I watched the video from a desktop yesterday and was puzzled by the 3D description.

As for the water spray, yes, that's been known from the previous overhead video.  One take on it is that they only used the water on the first few times because they were reacting to the deck doom scenarios posted on NSF and the proposed solutions.  Now that they see they don't need it they know not to take advice from NSF postings.  They'll probably go with engineering analysis from now on.   ;D

FYI you can click and drag on the video when using a desktop to look around...

IIRC, when examining the FCC permits for transmission, the support ships are positioned roughly 10 (statute?) miles from the ASDS.

Now that Space X have proven their accuracy for landing  on ASDs, I wonder if they will be allowed to stand off at a much closer distance. 10 miles distance now seems way over the top for safety constraints.

I don't know for a fact but I think the safety concern is the IIP of debris and/or the rocket if something goes horribly wrong.
Space is not Highlander.  There can, and will, be more than one.

Camera operator is on point with Ocisily views.

What is the yellow apparatus at the starboard rear of OCISLY? Seems like it has two vertical bars in back, a cylinder inside, and perhaps a ladder on the deck side? It seems to be overhanging the stern slightly.

I noticed that thing too, I think it may be new. Got good screen shots of it, but don't think I can post them for IP reasons. On the other hand, it is not an angle we usually see Ocisly from.

Kind of like watching paint dry...slow transit of Ocisly and tug...


......Aaannnnd we are done...web cam now showing another ship...hopefully the next time we see Ocisly there is another Falcon 9 standing tall on her deck....

I saw nothing on Marinetraffic for EIII today or yesterday when the three ships were splashing around the harbor.  Kinda odd considering Marinetraffic has a receiver bolted to Fishlips.  I only see one current hit and no path / track from EIII on Vesselfinder.  Is anyone seeing better with the other services?
