SpaceX has announced that F9 flights 14 & 15 will attempt "solid surface" landings. Where will that "solid surface" be? (These will be Cape launches).

Do we know the payloads?  That will help.

Now shown as Orbcomm and CRS-5.

And Ed, you pointed out in another thread the mention of landing on a "floating launch pad," so that does open the door to the notion of a barge landing attempt with the barge anchored near shore. Which might be easier for SpaceX to get approval for at this point than an attempted landing on Cape terra firma.

Edit: corrected "Cape" per Jim.  ;)

Orbcomm OG2 and TurkmenSat 1 according to Wikipedia.
Orbcomm OG2 and CRS-5 according to SpaceX's manifest.

I hear those things are awfully loud. It glides as softly as a cloud. What's it called? Monowhale!

Orbcomm OG2 and CRS-5 according to SpaceX's manifest.

I think the Wikipedia editor that interprets the statement that way is wrong - TurkmenSat 1 weighs 4.5 tonnes and goes GTO so it would definitely require high performance, definitely not a candidate for the landing attempt flights. I have make the changes at Wikipedia so that it would fit with SpaceX's manifest as well as the press release wording.  ;)

Wikipedia more likely correct, I would think, since TurkmenSat probably a low-energy mission that should leave plenty of margin for boostback.

Nope, TurkmenSat is a 4.5 tonne comsat going to geostationary - far from being a low-energy mission. In fact Turkmenistan originally asks the Chinese to launch it (on their most powerful rocket right now - the Long March 3B - would have happened next month if the plan was followed), until ITAR revisions caught up with satellite producer Thales Alenia Space and it can't be launched by the Chinese!  ::)

Thanks, GalacticPenguin, mistaken assumption deleted.  ;)

So, where will they attempt landing? On Cape terra firma, or on a barge?

Edit: corrected to "Cape" per Jim  ;)

FYI, they are not landing nor do they launch from KSC.  The launch and landing sites are on the Cape.  KSC=/ Cape

Are there any disused oil platforms with helipads in a location that could be used?

Duly noted. Now, since we have your attention, where will they try to land?

Speculation on this forum has been that the following two areas are contenders for early landing attempts. (see image)

Think it more likely at location B IMO. Is that LC-46?

If they options, would it depend on launch trajectories? Sometimes SpaceX heads to the equator, sometimes they head northeasterly. I would think the shortest distance is the best option all else equal.
Watch out for those pesky corners, they have teeth.

I seem to recall that the master plan map showed a planned circular landing pad north of the LC-39 complex. I think that's the area that Lars_J marked "A" on his map above. Has work started on that pad yet?

It will be a long time before anything launches or lands northo of LC39.  It's a swamp, a protected national park swamp.

There is plenty of developed land at CCAFS that hasn't been used in decades.  Easy access to roads back to SpaceX facilities.

I was watching a YouTube montage last night of launch failures. It is curious to me that we've become so nervous of a nearly empty returning stage, with a flight termination system when back in the glory days fully loaded vehicles use to put on all kinds of fireworks.

I wish we could just grow a pair and go for it.  Worst case range safety blows it up.

I was just rereading the statement released by SpaceX with the video and was struck by this sentance.

Quote
At this point, we are highly confident of being able to land successfully on a floating launch pad or back at the launch site and refly the rocket with no required refurbishment.

Assuming they fly the core back and land somewhere at the Cape and it's now already there needing "no required refurbishment".........

They wouldn't be planning to.......

Naaahhhhh.....

Would they?

I have simply observed that SpaceX likes to move much faster with their testing than others generally do.

They don't skip steps, but they move fast.

Perhaps, if they get a core to return to the Cape, they will leave it there and relaunch it.

I doubt they could do it with a paying payload, but I could see Elon loading a dummy paylod and launching it just to show he could.

EM is on record as saying they'll land a core on land this year and relaunch a used core next year... so yah, that's what's happening.

Note: I suspect the returned core(s) will undergo re-testing at McGregor until they're sure of launch integrity
