MINISTRY OF TOURISM, INVESTMENTS & AVIATION SECURES HISTORIC AGREEMENT WITH SPACEX TO PROPEL BAHAMAS INTO THE SPACE TECHNOLOGY & TOURISM FRONTIER
[Feb 16]
Quote
SpaceX, a pioneer in space exploration, is currently finalizing mission designs where one of the company’s autonomous drone ships will serve as a Falcon 9 landing location east of The Exumas, offering a spectacle that will be visible only in The Bahamas. This unique opportunity sets the stage for tourists to witness awe-inspiring space events from cruise ships, resorts, and various tourist hotspots, solidifying The Bahamas' position as a key player in the emerging space tourism industry.

In the attached Google Maps the red circle is Exumas, so the landing zone would be the area east of that (in orange).  Currently, Starlink launches from the Cape have to do a right dog leg to avoid a Bahamas flyover.  With this agreement, a flyover would allow a straight ground track (and possibly save fuel by eliminating the Delta-V?)

Will this in theory mean calmer seas more often for an ASDS landing there, and faster transit back, increasing launch availability?

Just a theory, slightly further away means long travel time, but calmer waters allow for safer landing conditions and faster travel return time.  As for increased launch cadence, SpaceX is still limited to two drone ships, and the need to perform RTLS is still needed when drone availability is limited.  The RTLS cost them a few fewer Starlinks Sats, but the Delta-V saving may allow some added Starlinks Sats.  I'll wait for the members with the math skills to do the calculations on this.

Another theory suggests that the fleet heads towards the Bahamas at Exumas and uses a single barge to transport multiple boosters back to Port Canaveral before returning to Exumas. This approach is similar to the one used on the West Coast where a single drone ship docks at Long Beach and heads out for another landing, while a separate barge collects a couple of boosters and then departs for VSFB. The boosters are then dropped off at their port and the barge returns for more.

Do boats have to stay outside the orange delineated area?  If not, how close to the ASDS barge can they approach?  Am I correct in thinking the Bahamas government has all authority to regulate the waters & airways that are territorial to the Bahamas? 

Watching from hotels or any of islands/beaches seems like it will not be impressive.  Landings will be at least 20-60 km away.   

I am guessing somewhere in the agreement the Bahamas is going to regulate this somehow, & also indemnify SpaceX.

So is there a fast transit ship that has to make an appearance soon?

I wonder if they have been looking into landing on an island in the Bahamas?  Would reduce operating costs and launch constraints on sea state.  Although doing so would still require boosters to be shipped back to Florida, so savings might be small.

Cross-post; ASDS landing here did not happen:
Cross-post; launch NET May 1, launch trajectory to the southeast; ASDS landing amidst the Bahamian islands in Exuma Sound the Tongue of the Ocean:
Starlink 4-15 permit request finally showed up, and the drone ship location is a bit interesting.
0598-EX-ST-2022

Since this was filed after the permits for higher numbered flights, I'm wondering if it's the rideshare for Spaceflight.

Probably fill it up anyway so more a case of providing more margin and/or greater possible mass?

The first use of the new landing zone has been noted.  I'll update you with a map when made available.

Yes, I expect that Musk has already acquired one of these islands near the landing area that has a preexisting harbor.  Build a resort with an airstrip. Base one of the ASDS locally at this location and then transfer to a cargo ship for the trip back to the Eastern Range. (as you point out like on the West Coast)  Then the ASDS is only 15 miles from the landing zone. This increases cadence dramatically.

You would hope but maybe not.  I need to do some digging to see what port is available.  Already four launches are using the new landing zone (they didn't wait long to start using the agreement).  I suspect the initial landing will use the same routine with the fleet returning to Port Cavernal.  SpaceX just purchased and offloaded a second crane at that port. So having a port in the Bahamas would require yet another crane.

Yea, What?

Speculation hell.

As promised above I look at all the islands and the only candidates for a preexisting harbor are one at Freeport and 2 at Nassau.  The commercial port at Nassau is perfect, about as large are Port Canaveral. There are numerous small ports for pleasure crafts and yachts in the target area but would have to purchase land for off-load/load ops and dredge out a harbor, build a dock, etc.

If SpaceX intends to offload cores and farings onto a separate barge that ferries them back to Port Canaveral (and that's highly speculative) it would be this one at Nassau.
 
Don't hold me to this, I'm only providing current dock facilities possibilities

I'm sure the new crane and the existing on that SX uses so frequently are both the property of Port Canaveral See also https://www.portcanaveral.com/mhc-2
No one seems to have said this - but Blue Origin is moving into Port Canaveral right next to SX. Maybe they too expect a harbor crane to be available. (Although the brand new crane above the words "Port Canaveral" in this tweet is BO's) https://twitter.com/SpaceOffshore/status/1714004168359198811

Why land on a barge and not on shore?

For armchair rubberneckers who would like to explore the options, a google maps link to the area

https://www.google.com/maps/place/24%C2%B018'56.6%22N+76%C2%B010'36.6%22W/@24.4235032,-76.5651606,214210m/data=!3m1!1e3!4m4!3m3!8m2!3d24.315719!4d-76.17684?entry=ttu

Not a lot of great options for land landing point that also has a decent harbor for barge access and the roads to a wharf, while having the landing point be reasonably isolated.


There is a former airstrip near Freetown

https://www.google.com/maps/place/24%C2%B047'20.6%22N+76%C2%B018'28.5%22W/@24.7876853,-76.3387612,13349m/data=!3m1!1e3!4m4!3m3!8m2!3d24.789062!4d-76.307927?entry=ttu

That has a harbor north of it by a decent access road with a wharf where a barge could dock

https://www.google.com/maps/place/24%C2%B050'07.8%22N+76%C2%B020'32.2%22W/@24.8269521,-76.3544733,9997m/data=!3m1!1e3!4m4!3m3!8m2!3d24.835511!4d-76.342278?entry=ttu

but also what looks like a barge hideaway just south of the harbor that could be used

https://www.google.com/maps/place/24%C2%B049'45.6%22N+76%C2%B020'38.0%22W/@24.827248,-76.3474028,2163m/data=!3m1!1e3!4m4!3m3!8m2!3d24.829333!4d-76.343874?entry=ttu


The Freetown area is closer than Nassau to allow faster cycle time, but no crane. The airstrip is almost but not quite clear of the inhabited area of the harbor from a trajectory perspective.

Yes it has, in the Blue Origin thread, it started when that Twitter post was made last October.

I think a big question I have is whether there will be idiot boaters out for the F9 landings in the same way there were for the first Crew Dragon splashdown along the gulf coast. Landing far offshore in the Atlantic has a way of keeping the riff-raff out. This location is 14-18 miles from various islands all around it.
