Regarding the new gear (ladder); when OCISLY was returning with the F9, OCISLY was boarded (this was heard on the radio, apparently) by some SpaceX personnel just off Canaveral harbor. Some of these are speculated to have been VIP types, and thus high up in the company. They, even moreso than general SpaceX crew, would tend to be unaccustomed to the normal methods for ship to ship boarding - jumping/climbing. I also suspect that Cameron D is right regarding a safety inspector, especially if said inspector was aware that OCISLY had been boarded by novices (Novices at boarding ships at sea). That's a very different thing than being boarded only by a tug crew. 

In general, changes like this are what I expect to see for the ASDS; small changes based upon operational experience.

I'll also make a purely speculative (based in no evidence) prediction for another such change; a tarp for the lower portions of the F9 will be added to OCISLY's gear (it it hasn't already) and used to protect the F9 engine area from spray during transit.

off shore crew transfer

IMHO, it's a bit soppy really.  What's wrong with using a rope ladder?  Either that or they should learn to jump just like everyone else..  ::)


Horatio Hornblower certainly would not have approved. I recall he had pretty strong disdain for use of the bosun's chair. A sailor uses the ropes only. Ahh...I need to read those books again.

Patrick O'Brian 's Aubrey–Maturin series (Master and Commander, etc) is way better IMO; spend your time on those instead.

But we're way off topic.

I disagree with both those statements: (a) that there was any suggestion they use a bosun's chair and (b) that Patrick O'Brian's series comes anywhere close to CS Forester's..

But we're way off topic.

..but on this I do agree.  Here's hoping something happens soon - before we all go overboard!  :)

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.

The most important question for OCISLY is, have they renewed the 4-leaf clover?

Yup it is there :)

The be quite honest, given the years of valuable arm-chair engineering design critique NSF has provided (in this thread alone) I'm a bit surprised no-one has yet scrawled "We love NasaSpaceFlight" right beside it...  Hell, they know we're looking!!!
 
..and on that note, I'm even more surprised SpaceX hasn't chosen to deliberately install some obscure urban artwork on deck someplace just to give us something else to feed on.  ::)

Is the plan to eventually leave the ASDS on station and transfer the booster to a horizontal cradle on a GO ship with a crane?

None of the three different helper ships is even remotely big enough to do that.

There has been prior discussion of many variants on this approach.

Be aware... that getting the "beanie cap" swinging from a crane lined up with the top of the stage...
...while both the stage and crane are moving about on the open seas...
... will be almost 'mission impossible'...  :P
It took a long time with the crane on dry land and the stage on a ship in port...  :-\
Just saying...  ;)

See the discussion about 10 pages back about active stabilization for cranes.   Offshore energy development in the North Sea has advanced the state of the art.   Doesn't look cheap, though; until the launch rate increases it likely won't save them any money over bringing the barge back to port.

So that got me looking at my phone.  Its black with a flat screen.  When I lay it down face up it has some resemblance to an ASDS.  Perhaps someone could market a case that has bow angle, containers, blast wall etc., and an app that puts the circles and "X" on the screen?

Shapeways probably has a case design that would fit whatever phone you have. Add the containers/blastwalls and the other bits to the model and do a multi-color print. Then all you need is a screen wallpaper to match. No app needed. Can probably hire out the design work for not too much - Low detail and not too much of it. Plenty of reference photos to work from, Too.

Id buy one, if it was IPad size. It could be more detailed, as there would be more room to work

So now I've got interest in two of them in two sizes and one of them is potentially a paying customer.  Hmm...

I want one... or two. I have two Galaxy S5s

spawn a subthread? somewhere in the modeling/recreation section? we can carve out the posts, if desired. PM me.

Elsbeth III speed plot from Reddit user robbak:

http://i.imgur.com/846I7uy.png?1

The dip at the "4 May" tick mark is about 96 hours after leaving port and likely represents the "drop off" operation where EIII cut OCISLY loose at the landing zone.

So they reached the LZ about 24 hours before the planned launch time.

This might be mission update level, but when in doubt as they say, notification option under free services at Marine Traffic is "Sailing in high winds", you set the speed (I'm using 30 knots), which apparently includes areas beyond the coastal receivers.

Those high winds were probably the last storm front passing through.

Fortunately, winds near the LZ are at 20 knots now and falling. By midnight they are forecast to be 13 knots, so the weather for landing will be near perfect.

(The above are not the exact landing coordinates, but close enough for weather purposes)
