Hrmmm, looks like my pick is pretty close - if the criteria is where the pad of the left leg sits. :)

Out of fairness and to avoid cheating, I suggest that either Octograbber not be allowed to participate in future landing bingos, or that the initial landing point be used. :)

My sincere thanks to Helodriver and NSF for this landing bingo, on this very historic flight.

Its a shame Musk companies are known to be good with software. If this was a Boeing project it might be worth trying to hack Octograbber's controls, and drive it and F9 to the correct "landing" coordinates .... on second thoughts that might result in opposite movements until the propellant batteries were dangerously expended!

Even if it's a fixed game, there is still a certain level of randomness. Because there's two competing forces at work.

1. The individual who setup Falcon9 Stage 1 landing guidance and control tables.

2. The individual who setup the drone-ship which exact coordinates to hold.

So, with a simple algorithm, if you know which square each of them took (and under which pseudonyme) you know which square the rocket will actually land on.

I agree it's getting far too predictable ( Hitting the bullseye with every launch.) Let's make it more difficult.
On the the next one you have to chose 5 spots and predict the rocket center and the leg locations.
Of course you can only predict 3 leg locations if you specify the falcon will be leaning. ;)

Overly complicated. If you assume intact landing, you only need 2 points to fix down 2d translation and rotation. So center + leg number one
leg number 2-4 follow from that. Even if it goes so squat that the leg-diameter increases to the point it reaches different squares , those 2 points cover that, you get x coordinate, y coordinate, rotation angle and leg diameter.

How do we number the legs though. A good reference point is the racetrack on the side of the rocket. Clockwise or counter clockwise?

As always, helodriver gets the final say, but I'm thinking anything in the vicinity of K25 looks to be in the running.
Launches attended: Worldview-4 (Atlas V 401), Iridium NEXT Flight 1 (Falcon 9 FT), PAZ+Starlink (Falcon 9 FT), Arabsat-6A (Falcon Heavy)
Pilgrimaged to: Boca Chica (09/19 & 01/22)

Do we have a plot of winning squares? We should be able to calculate the odds of each square and increase the payout proportionally.

Octograbber covers like 16 squares but my submission of J-27 appears to be in there.

The Worm Has Returned!

Sailing in tall and proud aboard OCISLY, B1058.1 bearing the iconic NASA Worm logo, The arrival the successful return of NASA Crew Launch and the successful first flight of this brand new Block V booster.

As befitting a mission of such importance and profile, many onlookers and space photographers met the fleet, providing a plethora of high quality video and images from multiple angles making bingo judging a simpler process this time.

Helicopter shots taken by Ben Cooper and John Kraus were coupled with sea level shots by Julia Bergeron, Chris Gebhardt and Stephen Marr for triangulation with known ASDS features. The on board ASDS corner camera was also of great help, with the position I initially determined from a video screencap immediately after landing being exactly the square confirmed by the port arrival pix.

Combining these various images allowed determination of positional and rotational orientation of B1058.1 to a high degree of accuracy. So without further ado, K-25 is the winning spot chosen by mdspacefan!

K-25 please

Congratulations mdspacefan on your victory! Prizes will be on the way!

Brass ring for @pb2000 who correctly predicted/called the winning square after landing :)

Congratulations to the winner @mdspacefan, and well - to all of us, because we're all winners on this one.  Way to go SpaceX and NASA!

Sure it wasn’t L-25??
It was on the line coach!
Oh well 😁 congrats to mdspacefan from your grid-board neighbor!!

Nah, if anything it was closer to J-25... maybe need a recount? :D
